본 연구에서는 특급호텔 조리종사원이 인지하는 직속상사의 코칭 행동이 직무만족도 및 이직의도에 미치는 영향관계에서 LMX의 조절효과를 고찰하였다. 실증연구를 위해 확보된 211개의 표본을 바탕으로 연구모형의 신뢰성, 적합성 등을 검토하였고, 구조방정식 모형을 사용하여 총 3개의 가설을 검증하였으며 모형의 적합도는 χ²=156.316(p<0.001), df=51, CMIN/DF=3.065, GFI=.892, NFI=.912, TLI=.920, CFI=.938, RMSEA=.099 등으로 조사되었다. 연구결과, 상사의 코칭 행동은 직무만족도(β=.578)와 이직의도(β=-.423)에 유의한 영향을 미치는 것으로 조사되었으며, 직무만족도는 이직의도(β=-.254)에 유의한 부(-)의 영향을 주는 것으로 조사되었다. 이러한 결과를 통해 상사의 코칭 행동은 직무만족도를 향상시키고 이직의도를 낮출 수 있다는 결과를 확인 할 수 있었다. 한편, 직속상사의 코칭 행동, 직무만족도 및 이직의도와의 인과관계에서 LMX의 조절효과는 부분적으로 존재하는 것으로 나타났다. The purpose of this study is to understand the influence of supervisor coaching behavior in culinary staff’s on job satisfaction and turnover intent. Based on total 211 samples obtained from empirical research, this study reviewed the reliability and fitness of the research model and verified a total of 3 hypotheses using the AMOS program. The hypothesized relationships in the model test simultaneously by using a structural equation model(SEM). The proposed model provided an adequate fit the data, χ2=156.316(p<.001), df=51, CMIN/DF=3.065, GFI=.892, AGFI=.834, NFI=.9124, CFI=.938, RMSEA=.099. The model s fit, as indicated by these indexes, was deemed satisfactory, thus providing a good basis for testing the hypothesized paths. The SEM showed that the Relational coaching had a positive significant influence on job satisfaction, coaching had a negative significant influence on turnover intent. Also, job satisfaction had a negative significant influence on turnover intent. The moderating effects on lmx and job status do seem to exist. Limitations and future research directions are also discussed.

In recent years, explosive increase in population has been damaging mankind in terms of deprivation of natural resources and more of economical demands. Therefore, we have thought about problems as to counter-balance the increasing population, and reached a resolution of artificial methods of controlling birth. In the past, though now used in some of contraceptive methods, extravaginal ejaculation, condom were commonly used. But recently, pills, IUD and several kinds of operative procedures are quite popular. Though the recent methods are known to be effective compared with the traditional methods, a certain unwanted side effects as well as limited value of usages now must be discussed. On this aspect, we are trying to research for a ideal methods such as symptom free, more of natural way of family planning and try to zero the failure rate. And also it has been suggested that only if those scientific methods of controlling birth can be base on religious concepts of moral being, it will be enlightened. At the Happy Family Planning Clinic of St. Mary's Hospital, we apply Billing's ovulation method to out-patients who want contraception and usually advise them to use it on a self-care basis. For a retrospective study of the presurvey data analysis and use-effectiveness of the ovulation method from April 1, 1975 to Nov., 30, 1975, we have dealt with a total of 1,383 women (urban areas 465, rural areas 918). The results of preliminary survey were as follows; 1) Among 465 women in Seoul areas, the failure rate was 10.3, which signified unplanned pregnancies of 32 women. 27 of the 32 women were pregnant due to the users own failure and the remaing 5 due to the failure of the method. Therefore, the failure of the method accounted for 1.6. 2) Among 918 women in rural areas, the failure rate was 15.2 signifing unplanned pregnancies in 93 women. The cause of the failure in 81 of the 93 women was attributable to the user's own mistake and that in the remaing 12 to the default of the method. Therefore, the failure attributable to the method accounted for 2.0.

반음양환자에 있어서의 성염색체, 성선 및 이소성 요인등이 시상하부-뇌하수체축의 기능에 미치는 영향을 관찰하고저 LHRH 및 estrogen 부하시험을 실시하여 뇌하수체의 기능 및 시상하부의 고유기능인 음성 및 양성되먹이기전의 유무와 반응도를 관찰하여 다음과 같은 결론을 얻었다. 1. LHRH검사결과 모든 반음양환자에서 성염색체, 성선 및 이소성요인(ectopic steroid)들과 무관하게 뇌하수체의 성선자극호르몬의 생산분비기능은 소실되지 않았다. 2. estrogen 투여에 의한 시상하부의 음성되먹이기전은 반음양의 모든 환자에서 성염색체, 성선 및 이소성 요인들과 무관하게 보존되어 있었다. 3. 남성 및 여성위반음양 환자에서의 estrogen 투여로 일어난 시상하부의 양성되먹이기전은 Y-염색체를 가진 환자에서는 모두 나타나지 않았고, 성선 및 이소성 요인에 의한 환자군에서는 제한된 여성형으로 나타났다. 4. 진반음양환자의 estrogen투여에 의한 양성되먹이기전은 성염색체 및 성선의 공존상태와 무관하게 여성형의 반응을 보여 주었다. 5. 이상의 결과로 보아 반음양환자의 시상하부-뇌하수체축의 기능적인 모형은 남성반음양환자를 제외하고는 여성형 또는 제한된 여성형의 기능을 나타내는 것으로 보인다. To evaluate the functional unit of the hypothalamopituitar axis in various groups of intersex luteinizing hormone releasing hormone (LHRH) and estrogen provocation tests were perfomed in the 5 clinically classified groups of intersex. They included four cases of Turner`s syndrome, five cases of feminizing male intersex, six cases of adrenogenital syndrome, three cases of feminizing female intersex and three cases of true intersex. Among them six cases of adrenogenital syndrome were followed up after treatment; three of them manifested normal or spotting mentruation 6 months after steroid therapy. LHRH test, injecting 100μg of LHRH intravenously, were performed according to the procedures proposed by Nillus and Wide (1972) and for the estrogen provocation thest 20mg of premarin, a conjugated estrogen, was used as done by Aono etal. (1978).

본 연구는 육색이 다른 세 품종의 고구마 분말을 첨가한 양갱의 품질특성 및 항산화 활성을 평가하였다. 양갱의 색도는 주황미 첨가 양갱의 명도 및 황색도가 높았으며, 신자미 첨가 양갱의 적색도가 가장 높고 명도가 가장 낮았다. 당도는 54.00~56.33°Brix의 범위로 나타났다. 조직감은 경도에서 대유미를 첨가한 양갱이 1,985.13 g로 가장 낮았고, 씹힘성 및 검성에서는 신자미를 첨가한 양갱이 399.19 및 579.39로 가장 높았다. 총 폴리페놀 및 플라보노이드 함량은 신자미를 첨가한 양갱이 각각 124.81 mg GAE/100 g 및 47.30 mg CE/100 g으로 가장 많았고 주황미, 대유미가 그다음 순이었다. ABTS 및 DPPH 라디칼 소거능은 대유미 첨가 시 나타나지 않았으나 신자미 첨가 시 각각 34.76 mg AAE/100 g 및 70.88 mg AAE/100 g으로 높았다. 관능평가 결과 색, 맛, 식감을 비롯한 전체적인 기호가 신자미가 우수했고 주황미는 낮았다. 이러한 결과를 통해 고구마 고유의 육색을 살려 양갱을 제조할 수 있으며, 씹힘성, 검성, 기능성분과 항산화 활성이 높고 색과 향에서 선호도가 우수한 자색고구마인 신자미가 3품종 중 가장 적합한 것으로 나타났다. This study evaluated the quality characteristics and antioxidant activity of yanggaeng prepared with the addition of three different colored sweet potato powders (Juwhangmi, Sinjami, and Daeyumi). The brightness and yellowness values of yanggaeng with the addition of Juwhangmi were high. The highest redness value was observed in yanggaeng with the addition of Sinjami. With the addition of Daeyumi, the hardness showed the lowest value of 1,985.13 g, and the chewiness and gumminess showed the highest values of 399.19 and 579.39, respectively, with the addition of Sinjami. The total polyphenol and flavonoid contents were observed to have the highest values of 124.81 mg GAE/100 g and 47.30 mg CE/100 g, respectively, with the addition of Sinjami. Also, the ABTS and DPPH radical scavenging activities were observed to be 34.76 mg AAE/100 g and 70.88 mg AAE/100 g, respectively, with the addition of Sinjami. As per the results of sensory evaluation, yanggaeng with the addition of Sinjami had the highest sensory score in overall acceptance, including color, taste and texture, and preference. These results demonstrated that it was possible to manufacture yanggaeng by adding colored sweet potato powders, and the Sinjami cultivar was found to be the most suitable for this purpose.

The edible roots of radish (Raphanus sativus L.) are consumed worldwide. For characterization and evaluation of the agronomic traits and health-promoting chemicals in radish germplasms, new germplasm breeding materials need to be identified. The objectives of this study were to evaluate the phenotypic traits and glucosinolate contents of radish roots from 110 germplasms, by analyzing correlations between 10 quantitative phenotypic traits and the individual and total contents of five glucosinolates. Phenotypic characterization was performed based on descriptors from the UPOV and IBPGR, and glucosinolate contents were analyzed using liquid chromatography-tandem mass spectrometry in multiple reaction monitoring mode (MRM). Regarding the phenotypic traits, a significant correlation between leaf length and root weight was observed. Glucoraphasatin was the main glucosinolate, accounting for an average of 71% of the total glucosinolates in the germplasms; moreover, its content was significantly correlated with that of glucoerucin, its precursor. Principal component analysis indicated that the 110 germplasms could be divided into five groups based on their glucosinolate contents. High levels of free-radical scavenging activity (DPPH) were observed in red radishes. These results shed light on the beneficial traits that could be targeted by breeders, and could also promote diet diversification by demonstrating the health benefits of various germplasms.
