송영선,Song, Young-Sun Korean Society of Food Science and Technology 1987 한국식품과학회지 Vol.19 No.5

The subcellular distribution of lipoxygenase in germinating soybean seeds (Glycine max[L.] AmSoy) was investigated by using differential centrifugation and sucrose density gradient fractionation. Most of lipoxygenase -1 and -2/3 activities was present in the supernatant fraction after differential centrifugation of homogenates prepared from three-day-old seedlings; only 1.5% of lipoxygenase activity remained in particulate fractions. The results of a sucrose density gradient fractionation (three-day-old) showed that the lipoxygenase activity coincided with acid phosphatase at the densities of 1.19, 1.23, $1.25g/cm^3$, even though most of lipoxygenase and acid phosphatase activities appeared in supernatant fractions. There was no indication that mitochondria contained any lipoxygenase activity, and it does not appear that glyoxysomes and ER contained any lipoxygenase activity either. 발아중인 대두콩에서의 lipoxygenase의 세포내 위치를 차별 원심 분리법과 밀도 구배법을 이용하여 규명하였다. 차별 원심 분리법을 사용하였을때, lipoxygenase활성은 거의 supernatant fraction에서 나타났으며, 1.5%의 활성만이 particulate fractions에서 나타났다. 밀도 구배법에서는 lipoxygenase와 acid phosphatase의 활성이 1.19, 1.23, $1.25g/cm^3$의 높은 밀도들에서 일치하였으며, 이것은 발아중 가수분해되는 단백질체내에 이 효소가 국재되어지는 것으로 사료되어진다. 다른 세포내 소기관인미토콘드리아, ER, 그리고 glyoxysomes에 lipoxygenase가 존재한다는 증거는 보이지 않았다.

한국 아동의 Rorschach Card Ⅳ와 Ⅶ에 대한 반응

宋英璇,Song, Young Sun 이화여자대학교 간호과학대학 1974 이화간호학회지 Vol.- No.8

성격형성에 있어서 가장 중요시되고 있는 것은 부모의 존재로서, 모친으로부터의 여성에 대한 동일화와 부친으로부터의 남성에 대한 동일화를 통하여 성에 대한 동일화와 자아에 대한개념의 바탕이 이루워지는 것이다. 따라서 어린 시절에 부모로부터의 성에 대한 동일화가 올바로 이루워지지 못한 아동에 있어서는 부모의 상징가를 지니고 있다고 가정한 IV와 VII에 대한 반응에 있어서 각기의 card가 상징하는 적절한 성에 대한 반응이 나오지 않으리라는 2차적인 가설이 또다시 설정될 수 있는 바, 그러한 가설을 확실시 하기 위하여 저자는 부모의 유무에 따라 나눈 group별 아동의 반응을 분석하여 다음과 같은 결과를 얻었다. (1) IV에 대한 긍정반응은 부모생존 group 58%, 고아 group 37%, 편부 group 36%, 편모 group 20%로 나타났다. (2) VII에 대한 긍정반응은 부모생존 group 70%, 편모 group 56%, 편부 group 48%, 고아 group 39%로 나타났다. (3) IV에 대한 부친 유무별 긍정반응 비교에서 부친 생존 group 53%, 부친사망 group 27%이었다. (4) VII에 대한 모친 유무별 긍정반응 비교에서 모친생존 group 63%, 모친사망 group 41%이었다. (5) IV에 대한 무반응 비교에서 편모 group 34%, 고아 group 15%, 편부 group 16%, 부모생존 group 11%이었다. (6) VII에 대한 무반응 비교에서 고아 group 33%, 편모 group 32%, 편부 group 28%, 부모생존 group 9%이었다. (7) IV와 VII에 대한 반응수 비교에 있어서 평균 반응수는 부모생존 group 2.6, 편부 group 1.8, 편모 group 1.7, 고아 group 1.6이었다. 본 연구를 통하여 다음과 같은 제언을 한다. (1) 이제까지 주로 외국에서 연구된 상징가 가설에 대하여, 문화적 배경이 다른 한국에 있어서도 신뢰도 및 타당도가 수립되기 위해서는 더 큰 규모의 광범위한 대상에게 실시해 보아야 한다. (2) 실제로 반응하는 내용이 어떻게 부친과 모친을 상징하는 의미로서 해석될 수 있는 지에 관해 좀 더 깊은 심리학적인 연구가 있어야 한다. (3) 가설검증을 위한 방법에 계속적인 연구가 있어야 한다. (4) 상징가 가설이 실제 이용될 수 있는 면에 대한 많은 연구가 있어야 한다. (끝으로 본연구를 함에 있어서 시종일관 지도와 편달을 하여 주신 朴助烈교수님과 후원해 주신 동부 교육구청의 조선생님, 소년의 집 양정, 연미, 연산, 연제국민학교 교장선생님들께 深甚한 謝意를 드리는 바이다) It is important for psychiatric nurses to know the meaning and method of various projective tests which give basic information about personality. The Rorschach test is the best known of this type of psychological test. Among the 10 Rorschach cards, IV card(IV) and VII card (VII) is regarded to have symbolic meaning for father and mother respectively. The purpose of this study is to evaluate the symbolic meaning of these cards through analysis of the responses to IV and VII. The subjects were as follows: 74 children who have parents (group I), 25 children who have only father (group II), 82 children who have only mother (group III), 57 children who have no parents (group (group IV). The results of the study are summarized as follow: (1) Positive response for IV : group I58%, group IV 37%, group II 36%, group III 20%. (53% of children who have father, 27% of children who have no father.) (2) Positive response for VII : group I 70%, group III 56%, group II 48%, group IV 39%. (63% of children who have mother, 41% of children who have no mother) (3) Failure or reject for IV : group III 34%, group IV 18%, group II 16%, group I11%. (4) Failure or reject for VII : group IV 33%, group III 32%, group II 28%, group I 9%. (5) Average total response for IV and VII : group I 2.6, group II 1.8, group III 1.7, group IV 1.6, Major suggestion for further study is to have more larger and wider scale research for establishment of the reliability and validity of the hypothesis which has been studied in foreign countries mainly.

발아중인 대두 (Glycine max)에서의 단백질 유동

송영선,Song, Young-Sun Korean Society of Food Science and Technology 1988 한국식품과학회지 Vol.20 No.5

발아 중인 대두와 두채 자엽부에서의 단백지 유동 현상을 광학현미경(LM)과 주사 전자현미경(TEM)을 이용하여 epidermis, vascular tissue 그리고 storage parenchyma에서 비교 관찰하였다. 발아 초기의 자엽에는 직경이 $0.1-15{\mu}m$에 해당하는 다양한 크기의 단백질 체(protein bodies)로 채워져 있었으며 epidermis와 vascular tissue의 단백질체는 parenchyma 세포보다 훨씬 적은 크기의 $0.1-5{\mu}m$였다. 발아가 진행됨에 따라, 단백질의 분해현상은 epidermis와 vascular tissue에서 먼저 시작되었다. 그 분해 유형은 먼저 침투한 수분에 의해 팽창된 단백질체의 외막에는 손상이 없어 단백질 체 내부와 외부로부터 가수분해가 일어났으며, 단백질이 완전히 분해도기 전에 단백질체 끼리의 융합 또한 관찰 되어졌다. 단백질체 분해의 결과는 세포내에 중심액포를 만든다는 것이며, 두채 성장 말기에는 액포막의 파괴현상도 관찰되었다. The mobilization of proteins in the cotyledons of germinating soybean seeds (Glycine mar [L.] Merr.) and seedlings was studied by using light microscopy and transmission electron microscopy. The cotyledon tissues of soybean. were packed with protein bodies(diameter $0.1-15{\mu}m$) where storage protein of soybean is deposited. Degradation of protein bodies started in the epidermis and vascular tissues. After swelling of the protein bodies, autolysis of storage proteins began while the external membrane remained unbroken. Hydrolysis of proteins could be internal or peripheral and fusion might begin before complete protein degradation. Possible instances of vacuolar fusion were encountered in some cells. In all cases, the result of degradation was the same; the central vacuole of the cell. At the late stages of seedling growth, breakdown of tonoplast was observed in some cells.

Recently, the government announced a plan to supply more than 300 thousands housing units through the designation of new cities and the securing of public housing as a plan to expand housing supply to stabilize the housing market in the metropolitan area. However, if the precise demand analysis is not accompanied by the selection of public housing sites, the sale of housing may fall short, and may cause a bigger problem in the housing market unlike the original intention of the government. In this study, case studies were conducted for four zones of public housing sites, and the type of public rental housing supplied to those districts was classified and analyzed based on the transfer distance among the tenant characteristics of the public rental housing. In addition, by comparing the transfer distance with the population migration statistics, characteristics of the transfer distance which vary by supply type are analyzed. It is believed that the analysis of differences in transfer distances by supply type could present a basic direction for research by improving the methodology of estimating the demand for public housing more precisely than the demand analysis method of establishing demand zones based on population migration statistics.

Recently, the scale of investment in the domestic office market has grown rapidly, and the demand for market information transparency is increasing as movements to revitalize indirect real estate investment are active. But information disclosure is quite limited and indicators for detailed diagnosis of market conditions are not enough. In particular, the price index, which can be used as a basic index for time point correction in evaluating asset value, an important factor as a denominator of the capitalization rate, has been released in various private companies in the past, but only some are maintained. Compared to the housing market, the office market has significantly less stock of the transaction unit and thus extremely low frequency of transactions, making it difficult to estimate a stable index using actual transaction cases. Therefore, this study intends to present a more advanced methodology for estimating the Seoul Office Price Index. To this end, the Bayesian approach was introduced instead of the OLS Repeat Sales model, which has been widely used, and the index was estimated using three Bayesian trend models. After estimating the index, as a result of comparing it with the index using the existing methodology, significantly improved index estimation performance was confirmed in various aspects such as the index stability, statistical reliability, and index change(Revision). However, additional considerations are still needed regarding the Revision, which is important in terms of the utility of the index. Nevertheless, this study suggested a way to solve problems that have been difficult to estimate a stable index due to low transaction frequency, and in the future, it is expected that more detailed market information can be provided by estimating sub-indices such as district or size category.

The housing market has been one of the biggest policy topics in recent years. Accordingly, interest in the trend of apartment price fluctuations has significantly increased. The home price index is an indicator that shows the price fluctuations. In addition, an asking price based index and a transaction price based index. Since the asking price based index appears smoother than the transaction based index and reflects market fluctuations later, more active use of the transaction based index is required. Despite the fact that the number of data has passed 10 years after the apartment transaction based index was disclosed to the public in Korea in 2009, there are still many difficulties in stabilizing the index for the subdivided market. Although numerous researches have been conducted on the methodology to improve the stability of the index targeting the office market, there is still limitations in producing reliable and stable indices. This study proposes a data processing method that enables more stable index creation by overlapping data from three periods, and evaluates the index estimation performance of the data overlapping method compared to the index calculation methodology that has been used previously.

진정성 리더십이 조직몰입에 미치는 영향관계에서 변화지지행동의 조절효과1

송영선(Song Young sun),이연주(Lee Yeon joo) 부경대학교 인문사회과학연구소 2018 인문사회과학연구 Vol.19 No.4

이 연구는 리더의 진정성 리더십이 조직몰입에 미치는 영향 관계에서 변화지지행동의 조절효과를 확인하는데 있다. 이를 위해 중소기업 재직자를 대상으로 설문조사를 실시하여 287명을 분석하였다. 연구결과는 다음과 같다. 첫째, 진정성 리더십의 하위요인인 ‘리더 자각’이 조직몰입에 유의수준에서 정적으로 영향을 주는 것을 확인하였다. 둘째, 진정성 리더십의 하위요인인 ‘리더 자각’이 변화지지행동에 유의수준에서 정적으로 영향을 주는 것으로 나타났다. 셋째, 변화지지행동의 하위요인인 ‘순응’과 ‘협력’ 모두 조직몰입에 유의수준에서 정적으로 영향을 주는 것으로 확인되었다. 넷째, 진정성 리더십이 조직몰입에 미치는 영향관계에서 변화지지행동의 ‘순응’은 ‘내재된 도더인식’, ‘협력’은 ‘리더 자각’에서 조절효과가 있는 것으로 나타났다. 연구결과를 통해 직원들의 조직몰입을 위해서는 진정성 리더십의 ‘리더 자각’과 변화지지행동의 ‘순응’과 ‘협력’ 모두 중요한 변인이라는 것이 확인되었다. 연구결과를 통해 이론과 실무적인 면에서 시사점을 제시하였으며, 연구의 제한점과 후속연구를 제안하였다. The purpose of this study is to confirm the moderating effect of change support behaviors on the influence of leader s authentic leadership on organizational commitment. For this purpose, a questionnaire survey was conducted on the employees of SMEs and analyzed 287 employees. The results of the study are as follows. First, we confirmed that leader’s ‘self-awareness’ a sub-factor of authentic leadership positively affects organizational commitment at significance level. Second, leader’s ‘self-awareness’ which is a sub-factor of authentic leadership has a statistically significant effect on change support behavior. Third, ‘compliance’ and ‘cooperation’ of change support behaviors were found to affect organizational commitment statistically at significance level. Fourth, ‘compliance’ has a moderating effect on ‘internalized moral perspective’ and ‘cooperation’ has a moderating effect on leader’s ‘self-awareness’. The results of this study showed that leader’s ‘self-awareness’ a sub-factor of authentic leadership and ‘cooperation’ a sub-factor of change support behaviors are important variables for the organizational commitment of employees. The results of this study are meaningful in suggesting theoretical and practical implications, and suggested limitations of the study and subsequent research.
