  • Pleurotus eryngii is one of the most commercially important mushrooms cultivated in Korea. However, the shelf-life of the fruiting body is short, limiting its export. A new hybrid strain H17 of P. eryngii was developed to extend the shelf-life by mono-mono crossing between monokaryotic strains derived from DanBi and KNR2774. Although the cultivation period of H17 was slightly longer than that of the reference cultivar Kenneutari No.2, the quality did not change and remained normal after a period of 65.0 days at $4^{\circ}C$. This result was significantly different from that of the reference cultivar Kenneutari No.2. Analysis of the genetic characteristics of the new hybrid strain H17 revealed a different profile from that of the parental and reference cultivars when random amplification of polymorphic DNA (RAPD) primers was used. These results demonstrate that H17 is a new cultivar with improved storability after harvesting.

  • A new calculation method of expected overtopping probability of rubble mound breakwater considering real tide occurrence has been proposed. A calculation method of expected overtopping probability of rubble mound breakwater was proposed by Kweon and Suh (2003). In their calculation, the fluctuation of tidal elevation was expressed by the sinusoidal change that yields the uniform distribution of occurrence frequency. However, the realistic distribution of tidal elevation should influence on the overtopping chance. In this study, the occurrence frequency of tidal elevation obtained from the real sea is included. The tidal elevation used in this study is collected from the east coastal part of Korean peninsular. Analyzing the annual data of the tidal fluctuation measured hourly during 355 days, the distribution of occurrence frequency is formulated utilizing by the normal distribution with one peak. Among the calculation procedures of annual maximum wave height, wave height-period joint distribution, wave run-up height and occurrence frequency of tide, only the annual maximum wave height is again chosen randomly from normal distribution to consider the uncertainty. The others are treated by utilizing the distribution function or relationship itself, It is found that the inclusion of the variability of tidal elevation has great influence on the computation of the expected overtopping probability of rubble mound breakwater. The bigger standard deviation of occurrence frequency is, the lower the overtopping probability of rubble mound breakwater is.

  • 새로운 돌연변이 불면잠 nmn에 대한 조직학적 관찰 및 생리 생화학적 분석 결과를 요약하면 다음과 같다. 부화 3일째가 되면 정상잠은 흉부가 흰색을 복부는 갈색을 나타내는데 비해 불면잠은 전체적으로 암갈색을 띠며 부화 7,8일경이 되면 대부분 치사한다. 잠기별 발현비율은 월년란에 비해 인공부화란에서 현저하게 높았으며 부화날짜별 불면잠의 발현비율은 3일동안 거의 비슷했다. 조직학적 관찰결과 불면잠의 탈피선은 정상잠의 그것에 비해 형태나 크기에 있어서 큰 차이를 나타냈으며 정상잠이 면중에 새로운 피부가 형성되는데에 비해 불면잠에서는 신피형성이 인정되지 않았다. 유충혈액중의 총단백질은 정상잠이 불면잠에 비해 훨씬 많았을 뿐만 아니라 질적으로도 수종의 단백직 성분에서 차이가 있는 것으로 나타났다.

  • 이 연구는 식생기반재 돌망태의 침식억지효과 및 녹화효과를 분석하는데 있다. 이 연구를 통하여 얻은 결론은 다음과 같다. 조사기간 중 평균침식량을 분석해 본 결과, 침식량이 가장 많은 순으로 보면 곡선부에서의 일반돌망태시공지(5,840 $cm^3$)>대조구(5,833 $cm^3$)>직선부의 일반돌망태 시공지(5,621 $cm^3$)>곡선부의 식생기반재돌망태시공지(4,298 $cm^3$)> 직선부의 식생기반재돌망태시공지(4,117 $cm^3$)의 순으로 나타나 식생기반재 돌망태를 시공한 것이 임도절토비탈면의 침식을 저감하는데 효과적인 것으로 분석되었다. 아울러 임도 곡선부의 식생기반재돌망태 및 일반돌망태시공지의 토양침식억지효과가 직선부보다 낮게 나타나 이러한 구조물은 곡선부보다는 직선부에 설치하는 것이 효과적일 것으로 사료된다. 조사기간 중 평균식생피복률은 곡선부에서 45(28~65)%로 나타나 동일한 기간 직선부 식생기반재돌망태시공지의 평균피복률 56(30~85)% 보다 약 11(2~20)% 낮은 값을 나타내어 직선부에서의 식생피복률이 높게 나타났다. 또한 임도절토비탈면에 시공한 식생기반재돌망태는 안정화된 이후 임도 절토 비탈면의 토양침식을 억지하는 효과로 인해 식생피복률이 증가하는데 기여하는 것으로 분석되었다.

  • New occupational qualification system built on NCS(National Competency Standard) aimed to induce industries, the final appliers of qualification, to play a leading role in designing qualification and to spontaneously apply such qualification standard to employment and promotion so as to reinforce universality of qualification. In this study, we verified the validity of NCS level of qualification categories for 130 occupational fields by redesigning NCS-based new occupational qualification system with a focus on 7 major areas, including mechanical field, which were found to have wide-ranging social ripple effect throughout society and high acceptability in 2014. The results of study on suitability at qualification level suggested the followings: First, there is a difference in number of competency units for each qualification category, depending on area. New qualification covering 7 major areas included 15.3 competency units for each qualification category, which exceeds the number of competency units(about 10 units) in subdivided NCS. By field, some difference was found with 7.9 competency units for cultural field and 22.6 competency units for information and communication area. Second, preference above normal level was observed in the criteria, procedure and method for determining qualification redesigning. However, preference below normal level was exhibited in connection with possibility of linkage with overseas qualifications, although preference was above normal level in relation to the suitability of design/qualification level and qualification categories based on lifelong career development path within scope of NCS as the criteria for determining the redesign of qualification categories. Second, we compared NCS level and SC(Sector Council level, and the results showed that NCS level was found to be somewhat well-defined. For the qualifications with different definitions, it was deemed difficult to determine superiority between NCS level and SC level. However, majority opinion indicated that it would be desirable to follow NCS level because NCS was created through collection of opinions for a prolonged period.

  • Weight change in the postpartum period is a dominant concern of new mothers recently. Postpartum weight retention has important public health implications as well, because retention of gestational weight can be a significant contributor to longterm obesity and associated health risks. As traditional medical practitioners have managed some problems from postpartum weight retention, use some terms translated in Korean like as postpartumedema, obesity. But those have been not given any discuss objective and with evidences for nomenclature. Now reports review normal postpartum weight loss patterns, as well as risk factors for weight retention, ancient literatures, so practitioners can assist their patients in achieving a healthy postpartum weight.

  • 이 연구에서는 내부 압력 변화의 변화와 소화기 사용연한 기간을 5년 신생, 5년 재생, 10년 신생, 13년 신생으로 산정하여 소화기의 성능이 겉보기비중 물성 시험 기준에 적합한지에 대해 분석하고자 한다. 실험 결과 소화기 내부 압력이 0%일 때, 사용연한 기간에 따른 분말소화기의 1차, 2차, 3차 산술 평균 분석 결과 모두 부적합으로 나타났다. 소화기의 내부 압력이 50%일 때 시료번호 12-8-신생에서 130ml로 측정되어 부적합으로 분석되었으며, 13년 신생 분말소화기의 시료번호 09-9-신생에서 145ml로 측정되어 부적합으로 분석되었다. 그 외 분말소화기는 모두 적합으로 분석되었다. 소화기의 내부 압력이 정상일 때 모두 적합하다고 분석되었으나, 13년 신생 분말 소화기의 시료 번호 09-06 신생에서 실험값이 131ml로 측정되어 부적합하다고 분석되었다. 실험을 분석한 결과 사용연한 10년부터 13년까지 분말소화약제 겉보기비중 시험에서 일부가 괴상화 현상으로 소화기 성능에 부적합 판정이 나왔기 때문에 분말소화기의 사용 연한을 기존 10년에서 7년 이하로 내구연한을 줄이는 방안을 고려해봐야 할 것으로 판단된다.

  • Objectives: The objective of this research is to develop new animal-experimental model for Sasang Constitutional Medicine, especially for partial Taeyangin(one of four constitution which has good pulmonary function and poor hepatic function) by AAP intraperitoneal injection, and to estimate from the viewpoint of obesity and lipid metabolism. Methods: The C57bl/6J mice was divided into 4 groups ; Normal group, AAP group, High-Fat-Diet(HFD) group, and HFD+AAP group. 200mg AAP was injected intraperitoneally to the AAP group twice a week for six weeks, and HFD group was fed with 60%-High-fat Diet for six weeks. HFD+AAP group got both AAP injection and 60%-High-fat Diet at the same time for the same period. In this period, We measured the weight and Food Efficiency Ratio(FER, %) once a week. After six weeks, We conducted the blood chemical test from the groups, and extracted the fat tissue to measure weight. Results & conclusion: In the liver function test, two AAP groups had higher AST and ALP, and normal LDH. The blood level of creatinine from all groups were normal. The rate in weight was lesser by 7.8% in HFD+AAP group, and had lesser FER than HFD group. Also They had lesser Total cholesterol and LDL cholesterol, and had more HDL cholesterol than HFD group. HFD+AAP group hadmore glucose in serum and lesser Insulin-like Growth Factor 1(IGF-1) than HFD group.

  • A new physiotherapy named Ciliary Muscle Training method and one successful case had been reported first for treatment of Posner-Schlossman Syndrome (PSS), also known as Glaucomatocyclitic Crisis. When a person observed a back and forth moving object, the ciliary muscle would involuntarily do sometimes tense and sometimes relaxant exercise which can relieve the tensive state of the ciliary muscle of patients suffering PSS disease. Through this period of continued treatment, this ciliary muscle training method can improve the health status of the ciliary muscle and finally achieve the purpose of curing PSS disease. In this successful case, the patient's feedback result was very good after receiving our suggested ciliary muscle training method as an attempt to treat PSS, ill right eye of this PSS patient showed normal appearance without any differences from the other normal eye, his vision test values of naked eye were both 4.9 under nearly 200 degrees of myopia. High intraocular pressure (IOP) was mitigated, measured IOP value was in the normal (≦ 21 mmHg) and comfortable state without PSS relapse until now. Therefore, ciliary muscle training method could be a potential clinical treatment approach to PSS disease.
