To develop the method for enhancing safety and added value in low-graded beef, 2 experiments were conducted using high pressure technology as follows. Experiment 1. Effect of High Hydrostatic Pressure after the Addition of Vegetable Oil on the Safety and Quality of Low-grade Beef Olive and grape seed oil (10% of meat weight) were added into the loin of low-grade beef, vacuum packed, and high pressure (HP, 600 MPa) was applied to investigate the effect on safety against pathogens, penetration of vegetable oil into meat, and enhancement of nutritional aspect. Non-HP (0.1 MPa) without any oil treatment was also prepared as a control. Color L* and b*-value of beef loin was higher and a*-value was lower than those of control after 600 MPa HP. Total aerobic bacterial number was 3 log CFU/g in control but no viable cell was detected in beef with 600 MPa. After 10 days of storage, increase by 3 log cycles was found in the beef without HP. No viable cell was detected in the beef with 600 MPa except for the beef with grape seed oil which was counted as 2.81 log CFU/g. All inoculated E. coli and L. monocytogenes were inactivated by HP and were not detected even 10 days of storage. The beef loin added vegetable oil without HP did not show any difference in fatty acid composition but that of 600 MPa HP treated showed higher oleic and linoleic acid content when olive and grape seed oil was added, respectively. Addition of olive oil showed inhibition of lipid oxidation in beef and sensory evaluation revealed that there was no difference in any parameter. Results indicate that addition of vegetable oil and application of HP enhance the safety of beef loin, change the fatty acid composition in health-befitted way, and obtain desirable texture and inhibition of lipid oxidation (olive oil treatment). This can be one of the good methods to enhance the safety and added-value to low-grade beef. Experiment 2. Effect of High Hydrostatic Pressure after the Addition of Conjugated Linoleic Acid on the Quality of Low-grade Beef Using high pressure (HP) technology enhancement of sensory quality and infusion of bioactive compound into meat was tested as well as the effect of safety insurance. To 2nd grade beef loin, 1) 1% (based on meat weight) of conjugated linoleic acid (CLA), 2) 1% of CLA + 15% of lecithin (based on CLA) (CL), and 3) CL + 1000 ppm of α-tocopherol (CLT) were added, vacuum packaged, and HP treated for 0.1, 300, 450, and 600 MPa. Surface color of the beef was changed as increase of L*-value and decrease of a*-value by HP treatment. pH and cooking loss were increased by increase of HP level. No difference found in fat content but higher CLA contents (18 times cis-9, trans-11 CLA and 206 times trans-10 and cis-12 CLA) were obtained in the beef added with CLA and treated by HP when compared with no pressure treated one. No evidence in inhibition of lipid oxidation by CLA or α-tocopherol. Texture analysis showed decrease of hardness and gumminess by CL + 450 MPa and CLA + 600 MPa. HP with 450 and 600 MPa eliminated aerobic bacteria in sample and this effect continued after 10 days of storage. Sensory panelists could not recognize the color difference between HP treated or not. Higher scores in overall acceptance and willingness to buy was obtained when the samples were treated by CL or CLA with 300 MPa HP. Results suggest that although there are some undesirable change occurred including meat color and lipid oxidation, the addition of CLA followed by HP treatment can be a good method to develop a safer and healthier meat product containing biologically active compounds.

This research is to examine the relative impacts of relational benefits(social, confidential, and special treatment benefits) and core quality(core product and core service quality) on relationship quality(relationship satisfaction and trust) directly and relationship commitment(emotional, behavioral, and temporary commitment) directly and indirectly through mediating roles of in the hotel and food service industry context. In order to empirically investigate the proposed model, the data were collected from 600respondents randomly selected from among the customers who visited the hotel and family restaurant if he or she agreed to participate in the survey. To encourage a higher and quicker response rate, the respondents were offered ball point and discount coupons of the restaurant. The twenty-three hypotheses were analyzed with LISREL 8.5 W. The eight of twenty-three hypotheses were supported. To test unidimensionality of the measures of each construct we employed scale refinement procedure. The results of reliability test with Cronbach's as, and confirmatory factor analysis warranted unidimensionality of the measures for each construct. In addition, convergent and discriminant validity of the measures was warranted from the result of comparisons of correlation analysis and measurement model analysis. The data were analyzed with structural equation modeling with LISREL 8.5 W and SPSS Win/PC 10.0. The result of the overall model analysis appeared as follows:x^(2) =544.85 (d.f.=153, p=0.000), GFI=0.92, AGFI=0.88, RMSEA=0.065, NFI=0.96, CFI=0.97, PNFI=0.70, Critical N(CN)=233.07. Since the result of the overall model analysis demonstrated a good fit, we could further analyze our data. The findings and implications are as follows: First, confidential benefits and core service quality had an effect on relationship satisfaction. Second, social benefits had an effect on trust. Third, special treatment benefits had an effect on emotional commitment. Fourth, relationship satisfaction had an effect on trust. Fifth, trust had an effect on emotional commitment. Sixth, emotional commitment had an effect on behavioral and temporal commitment. Finally, behavioral commitment had an effect on temporal commitment. This study found what factors play in the process of developing commitment from the relational approach and the core service one. That is, the findings specify clearly the mechanism that customers use in understanding of organization-customer relationship in service industries. In this regard, this research was to meet the call of previous studies (Iacobucci et al. 1994; Butcher et al. 2003), which suggest that marketing scholars should focus more on managerially relevant constructs that are associated with firm-customer interaction. For the relationship satisfaction's evaluations, core service quality and social benefits made substantial and significant impact on relationship satisfaction. The results suggest that both concepts should be regarded as the core of relationship-oriented marketing concept and indispensable for gaining a long-term relationship. The finding indicates that core service quality is still significant and substantial driver of customer satisfaction. It shows that improving service quality perceptions leads to higher satisfaction, in turn trust, and ultimately to stronger commitment. In addition, social benefits contribute to explain the relationship of firm-customer in service setting. This implies that social benefits are well placed to provide managers with a useful predictive tool. This also provides insights with managers that customers who maintained a service relationship with a specific service employee are likely to be more loyal. In summary, the findings tell us somewhat about why the customer satisfied. In other words, this study explain that customer's decision for entering into and maintaining a long-term with service firm is driven by their assessment of the core service and the relational aspects such social and special treatment benefits. Thus, the challenge facing service researchers is to investigate which factors influence the strength of the firm-customer relationship. The findings also are likely to support the Iacobucci et al.'s(1994) work, which explained overall satisfaction could be improved by either core quality or the friendly peripherals being good. However, given the size of the parameter estimates of the core service quality- and social benefits-customer satisfaction, it is clear that the strength of core service quality-customer satisfaction is a stronger than one of social benefits-customer satisfaction. This is consistent with the Keaveney's(1995) study that core service failure was the largest category of reason for service switching. It is also interesting to note that satisfaction and trust mediates the effect of social benefits and core service quality on the outcome variables such as affective, behavioral, and contemporary commitment. These results imply that the development of relationships based on trust and commitment(social approach) through combining relational benefits and core quality can be adequate to explain customer-service firm relationships. That is, this study shows that one way to get customer's commitment is engendering relationship satisfaction and trust using combined relational and core quality approach. In other words, the findings indicate that when consumers perceive the service firm to be trusted, they will be willing to emotionally involve in the relationship(affective commitment), will repeat buying(behavioral commitment) and will try to continue the relationship(temporal commitment). However, to get consumers' satisfaction, trust and commitment, service firms should offer relevant relational benefits and core quality.

統一後 北韓土地 私有化 方案에 관한 硏究

정연국 建國大學校 2003 국내석사

One of the most critical parts in preparing unification is how we are going to privatize North Korean land. The following are predicted to happen 1) social chaios 2) excessive amount of unification cost 3) recession of economy 4) disruption of the nation. On the other hand this may have some positive effects such as; 1) easy delivery of unification cost 2) main power of North Korea's development and security 3) opportunity to become economically powerful nation in the 21st century. To facilitate privatization, the most desirable way may be to have North Korea adapt a partial privatization under the boundary of communism just like that of China. However, this is not a realistic approach as we can not predict when we will have reunification on the Korean peninsula. And most of all this is not expectable to the incumbent North Korean regime. Accordingly, the Republic of Korea should continuously conduct and conclude a research and preparation on this matter. First of all we desperately need a research institute that studies privatization of land and goods of North Korea. We should remember the lessons learned from East Germany. East Germany established a institution dedicated to this matter and faced trial and errors. We should take this into consideration and be prepared now for the unification. A basic study on North Korea's government-owned property is also necessary. Meanwhile a long-term land development plan should be established with detailed concrete working plans. I stated some principles with respect to North Korea's land privatization. And the most desirable measure may be applying the non-compensation government-owned land procedure. If the original owner returns the land or if we introduce the compensation of land, this may cause a collective lawsuit or division of the Korean populace. And in this case the Koreans might be regretful of unification, or it will be inevitable to spend enormous amount of money and time for a long term. However, what may come before this is to make special laws or regulations concerning dealing North Korea's government-owned property. Of course this law should draw support and establish common ground among Koreans. According to this law, the North Koreans should first return their land to the government. And then following the needs of the government the scope and range of privatization should be decided. After some suspension period the North Koreans should sell their land to secure cost for unification. Additionally, the dealing of North Korean land should be based on other communist country's cases such as Germany. We should also consider our own uniquenss and our national characteristics. We should conduct various researches As mentioned earlier, the future of the nation depends on how we implement the land system. Real estate or land is the primary resource of wealth and is the basic of human life. To minimize the economic shock and to promote a soon stability on the North side, it is my sincere hope that the study of real estate should become an independent field rather than one branch of Economics. I also hope those who study real estate have an in-depth study on the North Korean real estate issue after reunification.

軍 지휘책임 제도와 운용 공정성이 지휘관의 몰입에 미치는 영향

정연국 수원대학교 2017 국내박사

본 연구는 군의 지휘책임 제도와 운용 공정성이 지휘관의 몰입에 미치는 영향과 운용 공정성의 조절효과를 검증함으로써 각 변인들이 어떠한 인과관계를 통해 지휘관의 몰입에 영향을 미치는 지를 분석하고자 하였다. 연구 대상과 시기는 국방대학교 안보과정 및 석사과정, 합동군사대학 합동참모과정에 수학 중인 현역 장교들을 대상으로 총 271 부의 설문지를 배포하여 265 부를 회수하였고, 결측치와 불성실 응답 등을 제외하고 총 256 부가 분석에 활용되었다. 조사 기간은 2016.12.20.~2017.1.8.까지 설문조사를 실시하였다. 이 연구에서 수집된 자료의 일반적인 통계분석은 SPSS V.22를 활용하였으며, 연구대상자의 일반적인 특성을 확인하기 위해 빈도분석과 기술통계분석을 실시하였다. 측정도구의 신뢰도와 타당도를 검증하기 위해 크론바하 알파(Cronbach’s α) 값을 이용하였고, 지휘관의 이력특성에 따른 종속변수들 간의 평균차이 검정을 위해 일원배치분산분석(One-way ANOVA)을 실시하는 한편, 연구모형에 대한 가설 검정을 위해 구조방정식 모형을 활용하여 확인적 요인분석과 조절효과분석을 실시하였다. 연구의 결과는 다음과 같다. 첫째, 군의 지휘관들은 지휘책임 제도의 명확성이 높다고 인식할수록 몰입도가 높은 것으로 나타났다. 둘째, 지휘책임 제도 운용에 따른 결과의 공정성에 대해 회의적인 인식을 가짐으로써 부대지휘에 있어 걸림돌로 작용하고 있었다. 셋째, 지휘책임 제도요인이 몰입에 영향을 미치는 데 있어 운용 공정성의 조절효과는 유효하지 않은 것으로 나타났다. 넷째, 지휘관들은 계급이 높을수록 지휘책임 제도와 운용에 대한 긍정적인 인식이 높고 몰입도가 높은 것으로 확인되었다. 이상의 연구결과를 통해 다음과 같은 몇 가지 시사점을 도출하였다. 첫째, 지휘책임 제도와 운용 중에서 지휘관의 몰입에 직접적인 영향을 미치는 것은 제도이며, 제도의 명확성이 높을수록 자신의 직무와 조직에 대한 몰입도가 높게 나타났다. 둘째, 지휘책임 제도가 몰입에 미치는 영향관계에 있어 운용 공정성의 조절효과는 유효하지 않은 것으로 나타났으며, 지휘책임제도의 명확성과 운용 공정성 중에서 지휘관의 몰입에 더 큰 영향을 미치는 요인은 제도의 명확성으로 확인되었다. 셋째, 지휘관들은 상위계급일수록 자신의 직무와 조직에 대한 몰입도가 높은 것으로 나타났으며, 소속 군과 계급에 따라 지휘책임 제도와 운용에 대한 인식, 몰입도가 다르게 나타난 부분에 대한 보완 노력이 필요한 것으로 판단된다. 넷째, 현재 군에서 실시하고 있는 지휘책임에 대한 교육이 충분하지 못하며 지속적인 개선이 이루어져야 한다. 이러한 연구결과를 바탕으로 앞으로 군에서는 지휘책임 제도가 존재함으로써 지휘관들의 활동을 위축시키는 불편한 것이 아니라 지휘관들이 오로지 한 방향만 바라보면서 직무에 충실하고 이를 바탕으로 자신이 속한 조직에 대해 긍지와 자부심을 가지도록 도와주는 촉매로서의 역할을 할 수 있도록 제도의 명확성을 향상시키는 한편, 운용의 공정성에 대해 보편타당하게 모두가 공감할 수 있도록 제도를 합리적으로 운용함으로써 지휘부담을 감소시켜 자신의 임무에 보다 적극적으로 임할 수 있도록 환경을 조성하는 데 힘써야 할 것이다. This study verifies the effects of commander responsibility system and operational justice and discovers the effect of commanders’ commitment by analyzing the cause and effect. The subject of studies were students enrolled in the securities course and masters course at KNDU and active duty officers registered at KJSC. A total number of 265 surveys were disseminated and collected and 256 results were used for analysis. Two rounds of surveys were initiated from 20 Dec 2016 to 8 Jan 2017. General statistical analysis was implemented by SPSS V.22 and frequency analysis and technical statistical analysis were used to uncover the general characteristics of the subject. To verify credibility and feasibility, Cronbach’s α was used and correlation analysis was applied to measure the level of correlation among variants and to gauge the vector. A One-way ANOVA was launched to verify the disparity among averages and structure equation mode was implemented for verification factor analysis and fine tuning effect analysis. The results of the studies are as follows. First, it was proved that the more military commander’s command responsibility defined to be clear, the higher the degree of immersion. Second, the hindrance to command was due to the skeptic view on the result of fairness when a commander implemented command responsibility structure. Third, there was no evidence that the operational justice moderates the effects of the commander’s responsibility system on commander’s commitment. Forth, it was verified that the higher the rank of the commander, the higher a positive perception and level of immersion. The following results were drew as an outcome of the study. First, command responsibility system has a direct impact to commander immersion and the more clear the level of the system, the higher the immersion of one’s task and commitment to organization was revealed. Second, the higher the immersion of task and commitment to their organization, commanders have a higher chance to be promoted to higher rank. Third, it is estimated that the disparity on the level of immersion on recognition of command responsibility system and its operations among different sources of commissions, services, and ranks are areas to be improved. ,Forth, the current education on command responsibility is not suffice, and continued improvements are necessary. Based on this study, the command responsibility system should serve not as a hindrance to limit the activity of commanders, but to encourage the commanders to funnel their efforts on their task with loyalty. Based on this, commanders will elevate pride and confidence and operate a fair and transparent operation of the system by establishing common ground among members. In this sense, a condition should be shaped that commanders will reduce burden and will more actively be engaged in conducting their mission.

The objectives of this study are to analyze the technical high school students' general point of views on mechanical drawing and the learning activities, the need and difficulty of the mechanical drawing course, and the drawing skill level and the requirement of the course in industrial fields. This study is also to present the educational devices properly on the mechanical drawing course based on the analysis. And the objects of the survey include students, teachers and engineers in mechanical fields. The results of the survey are as follows; First, according to the general point of views on a mechanical drawing, students, teachers and engineer all together feel the need of mechanical drawing education. The students, however, drop short of the concern about the course. So, the practice should be given much more weigh than the contents of textbook that they can be concerned about the class. Second, from the analysis of the attitude in the process of mechanical drawing class, it shows that most of the teachers rarely or occasionally make the use of wall charts, real articles and audio-visual materials. Teachers should be more concerned about the study of textbook and direct the students to have interest in the learning activities. Third, the survey shows that the difficulty on the mechanical drawing course is great. It is considered that teachers should try to adjust the level of difficulty. Finally, it should be taken into consideration that teachers continue to instruct students how to make out projection drawing or sectional drawing, and to fill up dimensioning through the more practical practice.

정연국 경상대학교 2002 국내석사

The aim of this study is to insure the substantiality of the curriculum of physical education and to make it more complete. For these purposes, this study is focused on the changed contents of the series of the revisions of the physical education by investigating the social background of each period, curriculums, teaching purposes, evaluations and the arrangements of the time. Through this method, we can provide the qualified materials which would allow us to go to the right direction of the physical education as well as learn how the physical education has been changed and developed. The followings are historical comparisons, analysis and synthesis which are based on the articles from the Ministry of Education and Human Resources and leading studies 1. From the first to the third revision of the curriculum had been done according to the demand of the nation and society, with 10 years of periodicity. After the third revision, curriculums have been revised with around 5 years of periodicity. They have been changed periodically and throughly, to reflect the rapidly changing international situation and to satisfy the social and national demands. 2. In the beginning, when the outline of the curriculum had been made, to clear off the influence of the Japanese era was taken as a primary purpose. From the first to the fifth revision, the government took the initiative according to the demands of nation and society. The sixth revision was changed to allow the local administrations to be involved in the revising process. The seventh revision made a landmark in that the revision was done according to the newly introduced curriculum making and implementing process which allows the schools to take part in the revising process itself. 3. The seventh revision focuses on the development of physical strength, leisure, rules, ability of physical expressions, and sound attitudes, while the past curriculums emphasized development, preservation of health, and plays. 4. Throughout the whole revising process, the teaching contents of the middle school have been focused on athletics. Recreation was added at the second revision and the close-order drill and circulating exercises were added at the third revision. In the fifth revision, the teaching contents were divided into three areas such as psychomotor area, cognitive area, and emotional area. In the sixth revision, development of physical strength was emphasized. In the seventh revision, the new concepts such as 'obligation' and 'option' were introduced. In the fourth revision, axis of evaluation has been introduced and has been specified into four sub categories in the fifth revision. At the sixth revision, purposes (of teaching), distribution of marks, types, methods, times and frequencies were specified. At the seventh revision, evaluation-related items, which have to be considered at the real school situations, were specified systematically through the concrete examples. 5. The changes of the standard of the time allotment are like the followings. In the beginning period of the curriculum, the school hours of the physical education changed depending on the situations of the individual schools. At the first revision, two school hours were given. At the second revision the school hours increased to 2 to 4 hours, while from the third revision to the sixth revision it has been kept to 3 school hours. At the seventh revision, despite the importance of the physical education, the school hours decreased to 2 hours.
