  • The objective of this study was to determine the fatty acid composition of newly developed tissues of germinated soybean seeds. Five soybean accessions with varied fatty acid composition were allowed to germinate in sand under greenhouse conditions. Seedlings were picked up after 4, 6, 8, 10 and 12 days of germination and freeze dried. The fatty acid composition of the newly developed tissues was analyzed by gas chromatography. Significant variation in fatty acid composition was observed between accessions, days of germination, and variety ${\times}$ day of germination in whole and the cotyledons. In the case of newly developed five tissues, significant variation in fatty acid composition were observed between days of germination except oleic acid for root, hypocotyl and epicotyl stem and except stearic acid for hypocotyl and unifoliate leaves while all the parameters were significantly different for accession. Significant interactions of accession and days of germination were observed for palmitic, linoleic and linolenic acid in all tissues; only for oleic acid in hypocotyl, epicotyl and unifoliate leaves; and only for stearic acid in root, hypocotyl, epicotyl and unifoliate leaves. During germination, the fatty acid composition of newly developed tissues changed dramatically but whole seedlings and cotyledons changed slightly. These tissues contained five major fatty acids as found in original seeds, but compositions were totally different from that of the seed: higher in palmitic, stearic and linolenic acid and lower in oleic and linoleic acid. New tissues conserved their fatty acid compositions regardless of genotypic variation in the original seeds.

  • Since 'Hanok Expanse Support' has been started in Seoul, its target was expanded from renovation to new construction and from 'Hanok District' to all area in Seoul. The newly built hanok with Hanok Expanse Support had to follow the standards about the form of the hanok and adapt to modern lifestyle. However, the newly built hanok were planned with 'kan' since it retained the traditional wooden structure. So their composition of kan were considered to be influenced by the standards of each district and modern lifestyle. Therefore the aim of this study is to understand the architectural characteristics of newly built hanok in Seoul since 2000 focusing on the kan composition. Because of the differences in site conditions and the district unit plan, newly built hanok in Hanok District have more limited changes than Other District. However, kan is composed variously in horizontal and vertical ways to make the most space according to site conditions and most of the newly built hanok have opened courtyard rather than closed courtyard layout. With kan composition in various directions and kan added under the eaves, kan is highlighted in form. On the other hand, the composition of kan as an interior spatial element has changed and weakened because the lifestyle has changed compared to the traditional hanok and the 20th century urban hanok. Also the regular kan composition of Mom-chae and Nalgae-chae has changed. And kan is divided regardless to the wooden structure. Also, with the added kan under the eaves the main kan is dismantled inside. This paper indicates that although there is an undeniable premise that the case is restricted to hanok received Hanok Expanse Support on the condition of following the standards of the form of hanok, it is a part of the transitional changes that hanok is experiencing.

  • Background: This study was performed to evaluate periprocedural factors, complications, and repuncture rate of the newly developed puncture needle and compare it with the routinely used puncture needle for ultrasound (US)-guided paracentesis. Methods: We retrospectively identified 137 patients who underwent US-guided paracentesis between July 2018 and March 2019. Among them, 82 patients underwent US-guided paracentesis with a newly developed puncture needle. The other 55 patients underwent US-guided paracentesis with a routinely used puncture needle. The periprocedural factors, complications, and repuncture rate were compared between the two groups using the Mann-Whitney U test and Fisher exact test. The repuncture-associated factors were assessed using logistic regression analysis. Results: There were no major or minor complications in either group. The rate of repuncture was significantly lower in the group using the newly developed puncture needle compared with the group using the routinely used puncture needle (p=0.01). The duration of the procedure was significantly shorter with the newly developed puncture needle compared with the routinely used puncture needle (p=0.01). In univariate analysis, the thickness of the abdominal wall (p=0.04) and the use of the newly developed puncture needle (p=0.01) were significantly associated with the rate of repuncture. In multivariate analysis, only the use of the newly developed puncture needle was significantly associated with the rate of repuncture. Conclusion: Using this novel puncture needle with a hard plastic sheath and plastic wings, the rate of repuncture and the duration of the procedure were decreased without complications of US-guided paracentesis.

  • 본 연구의 목적은 신혼부부 가구가 주거경제적 측면에서 부모로부터 독립하는지 여부를 실증적으로 증명하는 데 그 목적이 있다. 본 연구에서는 인구학적, 사회경제적, 주택 특성 및 주택 정책 변수를 활용하여 주거 점유 시 부모로부터의 지원 여부와 생활비 지원 여부로 구분하여 분석을 수행하였다. 아울러 본 연구에서는 주택시장의 공간적 이질성을 고려하여 수도권과 비수도권으로 구분하여 연구를 진행하였다. 본 연구는 종속변수에 미치는 요인을 규명하기 위해 이항 로짓모형을 적용하였으며, 신혼부부 가구의 다양한 특성을 반영할 수 있는 2015년도 신혼부부 가구패널조사 자료를 활용하였다. 분석결과, 수도권과 비수도권 모두 높은 주택가격과 교통 접근성 선호는 주거 점유 시 부모로부터 지원을 받는 것에 정(+)의 영향을 받는 것으로 드러났다. 반대로 대출상품의 활용은 지원에 부(-)의 상관관계를 보이는 것으로 드러났다. 생활비 지원은 주거지출 항목과 정(+)의 관련성이 존재하는 것으로 나타나 신혼부부 가구의 주거지출비 부담을 경감하는 것이 필요하다고 판단된다. 본 연구의 의의는 부모의 지원과 신혼부부 간의 주거경제적 연관성에 주목하여 분석을 수행하였다는 점과 이를 통해 신혼부부 가구의 주거독립을 위한 정책을 제안하였다는 데 있다.

  • The monthly ambulatory treatment days in newly detected hypertension group and known hypertension group were analyzed. The population was identified through the records of screening examination given by Korea Medical Insurance Corporation during the period from April to July, 1986. From the records of screening examination, 11,614 hypertensive patients were identified. By random sampling,959 patients were selected : among them, 544 fell under the category of known hypertension group and the other 415 fell under the newly detected hypertension group. The monthly ambulatory treatment days of these patients during the period from the April, 1985 to September, 1987 were analyzed in order to compare the exents of medical care utilization as well as to define and analyze the determinants responsible for the ambulatory treatment days between the two groups. The following results were obtained. 1) In the known hypertension group, no statistically significant changes in the ambulatory treatment days was observed after, in comparision to before, the screening examination. However, in the newly detected hypertension group the medical care utilization increased after the screening examination because of hypertension. 2) The ambulatory treatment days for hypertension of the known hypertension was statistically significant and higher than that of the newly detected hypertension group after screening examination. 3) There was no statistically significant change in the ambulatory treatment days in association with diseases other than hypertension in either group before and after the screening examination. 4) There was no statistically significant variable responsible for ambulatory treatment days in the known hypertension group. However, the income was a statistically significant variable in the newly detected hypertension group. 5) After the screening examination, the variables determining the ambulatory treatment days were the age of the patient and the diastolic blood pressure in the known hypertension group. These variables responsible for 2.02% of the total ambulatory treatment days. In the newly detected hypertension group, the income was a statistically significant variable which was responsible for 2.10% of total ambulatory treatment days. The above results satisfied the hypothesis that there would be no significant changes in the ambulatory treatment days before and after the screening examination in the known hypertension group. Also the hypothesis that there would be no significant change in the exents of medical care utilization for the diseases other than hypertension before and after the screening examination in either group was satisfied Also the medical care utilization was significantly higher in the known hypertension group than the newly detected hypertension group after the screening examination. This finding satisfied the hypothesis. This study was limited by the lack of considering fully the variables reponsible for the clinical symptoms of hypertension as well as for the individual characteristics. Thus, the result of this study are not fully adequate to define the determinants responsible for the exents of medical care utilization. In the future studies on medical rare utilization, additional variables should be considered.

  • The purpose of this survey was to investigate the status of dietitians' nutrition management in the elementary school lunch program. 84 elementary schools in Pusan that operated the conventional school lunch program system participated in this survey. They were grouped into schools that had started the school lunch program gofore('Previously") and after 1996("Newly"). 84.5% of dietitians were 20-29 years old and 44% of them had a career less 1 year old. 74.6% of "Previously" and 72.4% of "Newly" served their meals in the classrooms. The student's nutrition and preferences were mainly considered in menu planning in both groups. The standardized recipe was used in 90% of total schools but not effectively in both groups. The nutrient value of meals was evaluated by the dietitians in most schools. Nutrition surveys of the meals students ate at home were carried out in 27.3% of "Previously" and 13.8% of "Newly". Students preferences were studied regularly in 60% of "Previously" and 48.3% of "Newly" and students evaluations of meals served by the school lunch program in 52.7% of "Previously" and 34.5% of "Newly". In 92.7% of "Previously" and 72.4% of "Newly", nutrition education was executed but was done mostly by letterssent to students' parents(in about 95% of schools), with only 11.8% of schools educating within in their classrooms. There were few instructional media for nutrition education. The most of them used notice boards(48.0% of "Previously" and 41.6% of "Newly") . Evaluation studies on nutrition management, and nutrition education were hardly correlated to the dietitian's career and educational level. They were also not correlated to the number of meals served by the school lunch program. In conclusion, the status of the nutrition management in the elementary school lunch program was not good and schools that had started the school lunch program before ("Previously") and after 1996(Mewly") were not that different. It appears that most of the dietitians from elementary schools started the school lunch program before 1996 have followed the nutrition management method established in these schools. In order to have better management in the elementary school lunch program, we need to improve the dietitian's position and more studies in the fields fo better nutrition management and nutrition education should be done.ram, we need to improve the dietitian's position and more studies in the fields fo better nutrition management and nutrition education should be done.
