김연규 全南大學校 大學院 1983 국내석사

溫暖한 氣候條件으로 因하여 作付體系가 多樣한 南部 地方에서는 前作物의 收穫期 때문에 비교적 移秧期가 늦어 水稻 收量 構成要素의 第l要素인 穗數의 確保가 어렵고, 移秧期가 늦어짐에 따라 出穗期가 늦어 登熟期의 低溫으로 登熟率이 낮아지며 최종적으로 收量이 낮아지는 問題 등이 提起되고 있다. 本 試驗에서는 栽植密度를 달리 했을 때 單位 面積當 穎花數와 이에 따른 登熟率이 어떻게 달라지는가를 檢討하고자 統一系 品種 曙光벼와 一般系 品種 東津벼를 供試하고 栽植密度를 3.3㎡當 50, 70, 90, 110 株의 4水準, 移秧期를 5月 20日, 6月 5日, 6月 20日, 7月 5日의 4時期로 하여 試驗한 바 栽植密度가 增加할수록 最高分蘖期가 빨라지고 有效莖 比率이 直線的으로 減少되는 傾向이었으며 줄기의 굵기에 있어 栽植密度를 增加시킴에 따라 細桿이었고 早植의 경우는 單位 面積當 穗數의 增加로 晩植보다 細稈이었다. 單位 面積當 穗數는 密度 增加에 따라 直線的인 增加를 보였고 移秧의 早晩에 따른 變異의 幅이 曙光벼가 東津벼보다 크며 ㎡當 穎花數 40,000개(曙光) 및 30,000개(東津)에서 高位 收量을 보였다. 또한 密度에 따른 1, 2次 枝梗 및 穎花의 退化는 密植할수록 적어지며 曙光벼가 東津벼보다 그 傾向이 뚜렷하였다. 登熟率은 密度 增加에 따른 變異의 幅이 크지 않았으나 다만 晩植에 있어서는 그 效果가 뚜렷하였다. 收量變異에 있어서 曙光벼는 5月20日에서 6月5日까지 90株/3.3㎡, 6月20日 以後 110株/3.3㎡, 東津벼는 5月 20日에서 6月 20日까지 90株/3.3㎡, 7月 5日에서는 110株/3.3㎡에서 高位 收量을 보였다. This experiment were conducted to study the effect of spacing on the spikelets, ripening rate and yield in the multiple cropping system, south region of Korea. Two rice varieties, Seokwang(Indica x Japonica), Dongjin(Japonica) were transplanted on the spacing 50, 70, 90, 110, hills/3.3m²and transplanted on May20, June5, June20 ,July5. The obtainet Result could be summarized as follows; 1. As increase in planting density, the maximum tillering stage was earlier and the effective tiller ratio was decreased linearly. 2. It was fine culm in the high planting density and in the early transplanting because of increase in. 2 No. of panicles per m². 3. The No. of panicles per m² was increased linearly with increase in planting density, and the variation of No. of panicles per m² according to transplanting periods was greater in Seokwang than in Dongjin, and it was showed high yield when No. of spikelets per m² was 40,000 in Seokwang or 30.000 in Dongjin. 4. The degeneration of primary, secondary branches and spikelets was decreased with increase in planting density ,and there was more significant tendency in Seokwang than in Dongjin. 5. The rate of ripened grains was higher in the high density than that of low density on late season culture. However, it was not significant in the other plots. 6. The optimum spacing to obtain high yield was 90hills/3.3m² when transplanted on May20 and June5, and was 110hills/3.3m²when transplanted on June20 or later in Seokwang. However in Dongjin it was 90hills/3.3m²when transplanted from May20 to June20 and 110hills/3.3m², when transplanted on July 5.

Today’s computing technologies like the Cloud Computing have attracted more and more people to store their private data on Clouds. When people enjoy the advantages that are ease of sharing and cost saving, their concerns about data security also arise. For resolving this, encryption is needed for data saving in un-trusted storage. However, traditional encryption methods are not support fine-grained access control for encrypted data. CP-ABE (Ciphertext-Policy Attribute Based Encryption) is a kind of ABE(Attribute-Based Encryption) that was proposed to resolve the exact issue of fine-grained access control on shared data in un-trusted storage. There is essential issue when directly applying CP-ABE schemes to practical applications. It is user management like user revocation or user addition. In this paper, I proposed a new ABE scheme that the authority can invite new members to join or permanently revoke undesired members dynamically with general expressiveness of access structure.

This research was conducted to find differences between sub factors of career maturity depending on smartphone usage motivation and the effects of smartphone addiction and usage motivation on career motivation, an important development tasks of adolescent times. For this reason, questionnaire survey was conducted on 319 female students from 7th, 8th, and 9th grade in specialized high school located in Gyeongido region’s K city The major findings of this study are as follows: First, on differences across each grade on smart phone addiction and smart phone usage motivation with career maturity, significant difference was seen for smart phone usage motivation. 9th grade showed higher results than 7th grade for total factors and information acquisition in regards to smart phone usage motivation. Smart phone addiction and career maturity showed similar results regardless of the grades. Second, on correlation analysis on relationship between smartphone addiction and smartphone usage motivation with career maturity, discomfort of living/maladjustment, which are sub factors of smartphone addiction hadnegative correlation with career maturity. Moreover, smartphone usagemotivation showed meaningful positive correlation with career maturity. Sub factors of smartphone usage motivation showed positive correlation in order of immediacy, functionality and convenience, information acquisition, service integration, and relations maintenance. Excluding factors of entertainment and leisure, ostentation and trend, the higher smartphone usage motivation, the higher the level of career maturity. Third, looking at effects of smartphone addition on career maturity, discomfort of living/maladjustment, a sub factor of smartphone addiction, showed to have significant negative effects on career maturity, meaning greater the difficulties of everyday life arising from over usage of smartphone, lower the level of career maturity. Fourth, looking at the effects of smartphone usage motivation on career maturity, immediacy and relations maintenance showed significant positive influence on career maturity. This means higher desire to satisfy wanted function unrestricted from time or place, or if the smartphone is used to communicate with various people and sustain close relationships, results in higher career maturity level. On the other hand, using smartphone for ostentation and trend, or tokeep up with social fashions resulted in lower career maturity. Therefore, through this study, it can be established that only discomfort of living/maladjustment out of smartphone addiction had significant negative effects on career maturity and depending on the factors of smartphone usage motivation, there were significant positive and negative effects on career maturity. On this research results, it is hoped that directions to expand positive elements of smartphones on career maturity of youth be presented.

金連圭 全南大學校 産業大學院 2005 국내석사

K시내의 밀폐된 맨홀 15곳을 선정, 공기시료를 채취하여 조성을 분석하였다. 공기 중의 산소 및 질소의 농도는 TCD가 부착된 G.C를 이용하여 측정하였으며, Column온도 60℃일 때 산소는 1.12분에 질소는 1.56분에 검출되었다. 산소의 함량은 하수맨홀에서 19.33%~20.69%, 통신맨홀에서 20.03~20.68%, 그리고 도시가스 맨홀에서 20.53~20.72%로서, 이 중 도시가스 맨홀이 다른 맨홀에 비하여 산소의 농도가 높았고, 맨홀의 크기와는 무관하였지만, 맨홀이 위치한 환경의 영향은 있었다. FID가 부착된 GC 및 GC/MSD를 이용하여 메탄의 농도를 측정한 결과 하수맨홀에서 메탄의 농도는 6ppm~21ppm 이었으며, 맨홀의 하층부보다 상층부공기에서 메탄의 농도가 더 높았고, 맨홀의 깊이가 깊을수록 상층부와 하층부간의 메탄농도의 차이가 크게 나타났다. 그 외 인체에 유해한가스류나, 산소농도는 맨홀의 위치와 관리정도, 시간에 따라 약간의 차이는 있었지만 대부분 지역에서 기준치와 큰 차이는 없었다. Air samples taken from the sewage, cable and gas manholes in K city using air samplers and tedler bags were analysed for the composition of air using a GC(TCD). The retention time of the oxygen and nitrogen at the column temperature of 60℃ were 1.12 min. and 1.56 min., respectively. Contents of the oxygen were 19.33-20.69%, 20.03-20.68% and 20.53-20.72% for the samples taken from the sewage, cable and city gas manholes, respectively. Among the three, the oxygen concentration from the city gas manhole was higher than the others. The effect of the manhole size on the oxygen concentration was negligible compared to the location of the manhole. GC/MS was used to measure the methane concentration in the sample, and the concentration of methane in the sewage manhole was in the range of 6-21 ppm. The methane concentration in the upper layer of the manhole was higher than that in the bottom layer, and methane was not detected from the samples taken from the cable and city gas manholes. From these results, the manhole gas is not dangerous if the manholes are taken care of properly and there are no gas leakage in the city gas manhole.

Relations of Cooperation, Resource Exchange Networks and Performances of Middle School Athletes Kim Yeon-Kyu Department of Physical Education, The Gradute School Hoseo University Asan, Korea (Supervised by professor Kyungng-Sik Kim) The purpose of this study was to investigate the relationship between the cooperation and resource exchange networks of middle school athletes and their athletic performance. In other words, this study was conducted to analyze the structure of the cooperation and resource exchange network of middle school athletes and clarify the relationship between network variables and athletic performance. This study was carried out with the athletes belonging to elite sports teams of middle schools located in C city in South Chungcheong Province in 2016. The number of the sampled teams was four in total, which included two male teams and two female teams. The number of the cases was 47 people in total; the male athletes included 12 volleyball players and 12 handball players, and the female athletes consisted of 9 basketball players and 14 volleyball players. In this study, a survey was conducted using the Name Generator Questionnaire (NGQ). NGQ is a tool for measuring the degree of closeness with each nominated person. In this study, the participants were asked to prioritize the people who were involved in cooperation and resource exchanges. NGQ was constructed to allow the participants to nominate a maximum of three people and the validity of the questionnaire was verified through experts' discussion. With respect to the data analysis, the cooperation and resource exchange network was analyzed using NetMiner 4.2 and the correlations between network variables and athletic performance were analyzed using SPSSWIN. The conclusions drawn from the study results and discussions through the research methods and procedures described above are as follows. First, it was found that the structure of the network of cooperation and resource exchange of middle school athletes was generally constructed as one complete network, and it exhibited the phenomenon that the poor become poorer while the wealthier becomes wealthier; in other words, a small number of athletes were nominated by many other athletes. Second, it was found that informational, social, and material resources were exchanged through the resource exchange networks of middle school athletes, Specifically, informational resources were exchanged in the order of athletic information knowledge, athletic skills, school life, and sports goods purchase in terms of the types of exchanged resources, social resources were exchanged in the order of leisure life, conversation, shopping, and other kinds of sports, and material resources were exchanged in the order of foods, gifts, small sports goods or sports accessories, and living products. Third, the structure of the cooperation and resource exchange network of middle school athletes was found to be partially related to their athletic performance. In other words, the network density for athletic information, athletic skills, and tactical information sharing had a positive relationship with objective athletic performance. On the other hand, the network density of the material resource exchange network had a negative relationship with objective performance. The activity centrality of the network for conflict resolution, tactical information sharing, mutual cooperation, and informational resource exchange had a positive relationship with subjective athletic performance, and the betweenness centrality of the athletic skill network had a negative relationship with subjective and objective athletic performance.

광역권 통근시간 만족도 영향요인 분석에 따른 대중교통 이용 활성화 방안연구

김연규 인천대학교 일반대학원 2022 국내박사

This study analyzed the factors affecting wide-area commuting time and satisfaction for office workers who perform wide-area commuting. First, in the case of commuting satisfaction for wide-area commuting hours by region, commuting time satisfaction was relatively low in the metropolitan area as the average commuting time was high, and commuting time satisfaction was relatively high in the non-metropolitan area as the average commuting time was low. This affects satisfaction by transportation, and even if it takes the same time, satisfaction varies depending on the choice of transportation, and shuttle, commuter bus, and train are higher than commuting time. Office workers who choose city bus are less satisfied even if commuting time is short. Second, as a result of analyzing commuting time and satisfaction by residential area, residents of Seoul and Incheon increased their satisfaction when commuting time was longer than a certain period of time. In addition, in terms of the characteristics of commuting transportation, relative satisfaction is high in passenger cars with less than 60 minutes of commuting time by bus and passenger cars, 60 to 90 minutes of bus, and more than 90 minutes of rail. Third, looking at the characteristics of each transportation access time and waiting time satisfaction, railway satisfaction is the highest even at the same access time, and in the case of passenger cars, the deviation of satisfaction is large even if the access time is the same. In addition, in the case of waiting time satisfaction, the satisfaction of bus means was relatively high even during the same waiting time, and in the case of railways, the waiting time of the subway is relatively long even during the same waiting time. This shows that the higher the level of public transportation service in the metropolitan area compared to the non-metropolitan area, the longer the relative time even if it is the same time. Fourth, as a result of analyzing the factors affecting the satisfaction of commuting time, the longer the commuting time or the lower the satisfaction level is for office workers in the metropolitan area or the more they own a house. However, the longer men, self-employed, and average sleep time, the longer the average morning leisure time, and the longer the number of years of service, the higher the satisfaction. Sleep time and morning leisure time are highly related to fatigue, and men's responsibility as a family, self-employed people don't choose a store location independent of their residence, and the number of years of service increases satisfaction. Fifth, comparing the characteristics of the satisfaction of commuting time in the non-metropolitan area, the metropolitan area has a higher impact on individual and residential characteristics, and the non-metropolitan area has a higher impact on company characteristics, because the location of the residence becomes closer to the workplace. In the future, the government will establish or improve express railways and wide-area buses to reduce wide-area commuting time, and build urban highways to shorten passenger car use time, which will reduce commuting time, but qualitative indicators are more important. In other words, even if commuting time is long, life satisfaction increases, so quality of life is important, and it is necessary to improve commuting time satisfaction rather than simple indicators of commuting time, so both qualitative and quantitative aspects of commuting time need to be improved. 본 연구는 광역통근을 시행하는 직장인을 대상으로 광역통근시간 및 만족도에 영향을 미치는 요인을 분석하였다. 첫째로 권역별 광역통근시간에 대한 통근만족도의 경우, 수도권은 평균 통근시간이 높은 만큼 통근시간만족도가 상대적으로 낮으며, 비수도권은 평균 통근시간이 낮은 만큼 통근시간만족도가 상대적으로 높게 나타났다. 이는 교통수단별로 만족도에 영향을 미치고 있고, 동일한 시간이 소요되어도 교통수단의 선택에 따라 만족도는 상이하며, 셔틀 및 통근버스, 기차일수록 통근시간 대비 만족도는 높게 나타났으며. 시내버스를 선택한 직장인은 통근시간이 짧아도 만족도는 낮게 나타났다. 둘째로 거주 지역별로 통근시간 및 만족도를 분석한 결과, 서울시 및 인천시 거주자는 통근시간이 일정시간 이상 길어지는 경우 만족도는 높아졌다. 또한, 통근교통수단의 특성에서도 버스 대비 철도 및 승용차에서 통근시간대 별로 통근시간이 60분이하는 승용차, 60~90분은 버스, 90분 이상에는 철도에서 상대적인 만족도가 높다. 셋째로 교통수단의 접근시간 및 대기시간 만족도별 특성을 보면, 동일한 접근시간이라도 철도수단의 만족도가 가장 높으며, 승용차의 경우 접근시간은 동일하더라도 만족도의 편차는 크다. 또한, 대기시간 만족도의 경우 동일한 대기시간이라도 버스수단 만족도가 상대적으로 높게 나타났으며, 철도의 경우 배차시간대가 낮아 동일한 대기시간이라도 지하철의 대기시간이 상대적으로 길게 느껴지고 있다. 이는 비수도권 대비 수도권일수록 대중교통 서비스수준이 높아 동일한 시간이더라도 상대적인 시간이 더 길게 느껴짐을 알 수 있다. 넷째로 통근시간 만족도에 영향을 미치는 요인을 분석한 결과, 수도권 직장인의 경우 통근시간이 길어지거나, 주택을 소유할수록 만족도는 낮게 나타났다. 하지만 남성, 자영업자, 평균 수면시간이 길어질수록, 오전평균 여가시간이 길수록, 근속년수가 길수록 만족도는 높아지는 것으로 나타났다. 수면시간 및 오전여가시간은 피로도와 관련성이 높고, 남성은 가족으로의 책임감, 자영업자는 매장위치를 거주지와 무관한 곳으로 선택하지 않는 특성, 근속년수는 직장의 적응 및 습관 등이 만족도를 높이는 것으로 나타내었다. 다섯째로 비수도권의 통근시간 만족도 특성을 비교해 보면 수도권은 개인 및 거주특성에 영향이 높고, 비수도권은 회사특성에 상대적으로 영향이 높으며, 이는 수도권일수록 거주지의 입지환경이 직주근접형과 멀어지기 때문이다. 향후 정부는 광역통근 시간을 줄이기 위한 방안으로 급행철도 및 광역버스를 신설 또는 개선하고, 승용차의 이용시간 단축을 위한 도시고속도로 등을 건설하여 통근시간을 줄이는 양적지표도 중요하지만 통근시간의 만족도를 높이는 질적 지표가 더욱 중요하다. 즉, 통근시간이 길어도 그 시간이 만족스러우면 삶의 만족도 역시 높아지므로 삶의 질이 중요한 시대를 맞이하여 통근시간이라는 단순 지표보다는 통근시간 만족도까지 개선시킬 필요가 있어 통근시간에 대한 질적 및 양적 측면 모두 개선이 필요하다.
