The effects of KOH pretreatment and annealing conditions on the interfacial adhesion and the reliability between epoxy resin and polyimide substrate in the flexible printed circuit board were quantitatively evaluated using $180^{\circ}$ peel test. The initial peel strength of the polyimide without the KOH treatment was 29.4 g/mm and decreased to 10.5 g/mm after 100hrs at $85^{\circ}C/85%$ R.H. temperature/humidity treatment. In case of the polyimide with annealing after KOH treatment, initial peel strength was 29.6 g/mm and then maintained around 27.5 g/mm after $85^{\circ}C/85%$ R.H. temperature/humidity treatment. Systematic X-ray photoelectron spectroscopy analysis results showed that the peel strength after optimum annealing after KOH treatment was maintained high not only due to effective recovery of the polyimide damage by the polyimide surface treatment process, but also effective removal of metallic ions and impurities during various wet process. 연성인쇄회로기판에서 금속 배선 도포층 에폭시수지와 폴리이미드 기판 사이의 계면접착력과 신뢰성 확보를 위해 3가지 폴리이미드 표면처리 및 열처리 조건에 따라 계면접착력 평가를 하였다. 또한 고온고습처리 조건에 따른 에폭시수지와 폴리이미드 사이의 계면 신뢰성을 $180^{\circ}$ 필 테스트를 통해 정량적으로 측정하였다. 폴리이미드 표면 KOH 전처리 전의 에폭시수지와 폴리이미드 사이의 필 강도는 29.4 g/mm이지만, $85^{\circ}C/85%$상대습도의 고온고습 환경에서 100 시간이 지난 후 10.5 g/mm로 감소하였다. 그러나, 폴리이미드 표면처리 후 열처리를 한 경우 29.6 g/mm의 필강도값을 가지며, 고온고습 환경 후에도 27.5 g/mm로 유지되었다. 파면 미세구조 분석 및 박리면 X-선 광전자 분광법 분석 결과, 폴리이미드 표면 습식 개질전처리 후 적절한 열처리를 하는 경우 폴리이미드 표면 잔류 불순물들의 효과적인 제거 및 습식공정에 의한 폴리이미드 손상 회복으로 인해, 고온고습환경에서도 계면접착력이 높게 유지되는 것으로 생각된다.

본 연구에서는 저서다모류 군집의 구조와 생태학적 건강도를 파악하기 위하여 진도 해역과 제주도 해역에서 각 7개씩 총 14개 정점에서 2010년 8월부터 2012년 9월까지 총 5회에 걸쳐 반기별로 저서다모류 군집조사를 실시하였다. 저서다모류의 서식기질로서 퇴적물의 입도조성을 분석한 결과 진도 해역은 비교적 혼합질 퇴적상을 나타낸 반면 제주도 해역은 모래함량이 높은 것으로 나타났다. 총 14개 정점에서 출현한 저서다모류는 68종, 231 ind./㎡ 서식밀도를 나타내었으며, 진도 해역에서는 61종, 167 ind./㎡, 제주도 해역에서는 62종, 295 ind./㎡로 나타났다. 시기별로 출현종에는 차이가 있었으며 제주도 해역에서 전반적으로 종수 및 서식밀도가 높게 나타났다. 출현 서식밀도의 자료를 이용하여 우점종을 선정한 결과 진도 해역은 Heteromastus filiformis, Ampharete arctica, Prionospio sp., Sigambra tentaculata, Thelepus sp. 순으로 나타났다. 반면 제주도 해역은 Amphicteis gunneri, Ampharete arctica, Prionospio sp., Spiochaetopterus costarum, Heteromastus filiformis 순으로 나타났다. 종조성과 정점 간 유사도에 근거한 집괴분석 결과 정점 5와 6을 제외한 정점에서 진도 해역과 제주도 해역으로 확연히 구분되었다. AMBI 분석 결과 1.2-3.4의 결과를 보였으며, 모든 정점에서 Ⅴ등급 저서다모류는 출현하지 않았다. 따라서 본 연구에서 진도 해역과 제주도 해역은 지리적 위치 및 퇴적상에 따라 저서다모류 군집이 분포하는 것으로 나타났으며, 전반적으로 시공간적인 큰 변동 없이 비교적 안정된 군집을 형성하고 있음을 시사하였다. Assessment of benthic quality status was implemented along the subtidal areas of Jindo and Jejudo to understand faunal structure of polychaete assemblages and ecological quality of the benthic environment. Sediment analysis was characterized by well sorted of both mud and sand in Jindo, and a little higher sand in Jejudo instead. A total of 68 polychaete species were found at 14 sampling stations with a mean density of 231 inds./㎡, and 61 species, 167 inds./㎡ and 62 species, 295 inds./㎡ in Jindo areas and Jejudo areas. Dominant species found in Jindo areas were Heteromastus filiformis, Ampharete arctica, Prionospio sp., Sigambra tentaculata, Thelepus sp. and Amphicteis gunneri, Ampharete arctica, Prionospio sp., Spiochaetopterus costarum, Heteromastus filiformis in Jejudo. With a help of cluster analysis, it was found that the sampling stations showed distinctive pattern of the distribution pattern and benthic quality status in Jindo and Jejudo except sampling station numbers 5 and 6, respectively. AMBI analysis the results were 1.2-3.4, grade Ⅴ benthic polychaetes did not appear. It was evident that both Jindo and Jejudo had different sedimentary characteristics as well as distribution pattern of polychaete assemblages.

Multiple symmetrical lipomatosis (MSL), also called Madelung`s disease, is a rare disorder of unknown etiology and characterized by abnormal accumulation of large subcutaneous fatty masses in neck, shoulder, and upper trunk. MSL has known to predominantly affect middle-aged men with a history of alcoholism. Although the clinical course of MSL is considered to be slowly progressive, in advanced stage, fatty masses in the neck may compress the upper aerodigestive tract, resulting in dyspnea and dysphagia. The treatment of MSL is surgical resection, but radical excision is very difficult and recurrence after surgery is frequent. We report the case of 55-year-old man with long lasting MSL, which caused severe airway obstruction. This patient was admitted with progressive dyspnea and massive accumulation of fat around the vocal cord that was detected on a neck CT scan. This abnormal fatty infiltration in supraglottic region caused upper airway obstruction.

This study attempts to test the the differences between the mother`s child rearing attitude perceived by children and child`s social cognition. For the present purpose the following hypotheses are set as follows: 1. Mother`s child rearing attitude will be perceived differently by sex and grades. 2. Child`s social cognitive ability will be different by sex and grades. 3. Mother`s child rearing attitude perceived by children will influence child`s social cognition ability. 4. Mother`s child rearing attitude also will be different from social cognitive ability among sub-variables. 5. Mother`s child rearing attitude In description patterns, curiosity training, reason orientations, rule principles, impulse expression, reward and punishment, and purpose presentations will be related to child`s social cognitive ability. The above items cover hypotheses 4-l throught hypotheses 4-7. To test the above hypotheses this study utilized "Child rearing questionnaire" deigned by HongWoo Lee (1973) and tests developped by Flavell, Botkin and Fry. This study also produced contingency coefficient and gamma coeffient along with Chi square to test the significant differences between mother`s child rearing patterns and child`s social cognitive ability. The results of the study are: 1. Hypothesis 1. There is a significant difference in the perception of child rearing attitude by grades (***p .001, c=.268, gamma=.556), not by sex. 2. Hypothesis 2. was denied by grades in terms of the differences in social cognitive ability, but there was relative ablity, but there was relative relationship by sex (*p .05, c=.277, gamma=.350). 3, Hypothesis 3. Mother`s child rearing attitude perceived by children is highly related to child`s social cognitive abilitity (**p .01, c=.320, gamma=.600). 4. Hypothesis 4. Hypotheses 4-2, 4-3, and 4-6 were denied.
