In a previous study, we developed a new food additive as an egg yolk antibody (IgY) against carbohydrate digestion enzymes for the regulation of blood glucose level and weight control. The IgY delayed and decreased the increment of blood glucose level after administration of sucrose in human being by 30% in 20∼30 min. We also developed a lipase inhibitor as a water extract of two kinds of herb, Platycodon grandiflorum and Solanum melongena. Twenty three volunteers were subjected to the intake of the egg yolk IgY plus the herbal extracts for 50 days. In average, the treated subjects appeared to lose 1.96 ㎏ of body weight and 3.4 ㎏ of body fat mass during the treated period. Furthermore, Panniculus adiposus and breech size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of egg yolk IgY and natural herbal extract improve the obesity by the decrement of body weight and body fat mass.

We developed a dietary supplement using natural herbs and nutrients for the growth and exercise performance improvement. It called JR-22 supplement containing distilled extracts of natural herbs to remove bitterness and the addition of Vitamin B1, B6, Ca and xylitol. We investigated on the effect of JR-22 supplementation on the maximal exercise performance, IGF-1 (insulin like growth factor-1) concentration and antioxidant activity in SD rat model. In result, JR-22 supplement group was better than control group about 10% in exercise performance test and increased about 63% of IGF-1 concentration in blood. In addition, the oxidative damage induced by exercise was reduced by JR- 22 supplementation. Therefore, we suggested that JR-22 supplementation enhanced effectively exercise performance and IGF-1 concentration and reduced to oxidative stress in muscles. Also, we analysed biochemical factors in blood for the safety of JR-22 supplement. We known that there is no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity.

This paper studied application of the microemulsion of water/oil/surfactant/cosurfactant to cosmetics and pharmaceutices. Isostearyl benzoate, isopropyl myristate and liquid paraffin were adapted for oils, polyoxyethylene series for surfactant and propylene glycol for cosurfactant. And then microemulsion regions were investingated at length. It was found that the smaller interfacial tension of oil, the larger microemulsion region and it was also found microemulsion region became wide when HLB of oil was similar to HLB of surfactant.

국민기초생활보장제도의 수급결정 요인 : 부양의무자 기준을 중심으로

윤홍식 한국사회복지정책학회 2003 사회복지정책 Vol.17 No.-

본 연구는 가족 간에 이루어지고 있는 경제적 부양 실태를 통해 현형 기초생활보장제도의 부양의무자 기준의 문제점을 경험적으로 고찰하고 이에 대한 유의한 정책적 함의를 도출하였다는데 그 의의가 있다. 특히, 한국사회에서 가족 간의 부양의무가 노부(모)에 대한 성인자녀의 부양으로 이해되고 있는 현실에서 수급자와(부양의무자 기준에 의한) 탈락자의 비교분석을 가족 간 경제적 부양(intrafamilial financial support)의 실태를 통해서 현행 부양의무자의 범위에 대한 기준의 적합성에 대해 논의하였다. 이러한 본 연구의 주요한 정책적 함의를 개괄하면, 첫째, 현행 국민기초생활보장제도의 부양의무자의 범위는 그 적용에 있어 실제 가족부양이행의 정도에 근거해 직계존속에 대한 부양의무를 제외하고 그 외의 부양의무는 폐지되어야 한다. 둘째, 모자가구에 대한 동거하지 않는 부의 부양의무는 기초 생활보장제도의 부양의무자 기준에 근거하기보다 '아동양육비' 지급과 같은 다른 법률과 제도에 의해 강제되는 것이 효과적이며, 끝으로 가족부양에 대한 부양은 철저히 사적인 영역의 문제이므로 개개인의 자발적 결정에 일임하여 장기적으로 부양의무자 기준을 폐지하고 국가는 빈곤에 대한 사회안전망의 주체로서 그 역할을 우선적으로 수행해야 한다. This study aims to examine problems in the intrafamilial financial support criterion in the National Basic Livelihood Institution (NBLI) eligibility. Under the circumstance that the ideal understanding of intrafamilial financial support has extensively departed from reality in Korea, this study attempts to provide useful policy implications for reducing the blind spot of the NBLI through modifying the intrafamilial financial support criterion in the NBLI eligibility. This study demonstrates three major policy implications. First, the criterion needs to be maintained between parents and their adult children. Second, the intrafamilial financial support between noncustodial fathers and mother-only families should be enforced by other institutions rather than by the NBLI criterion. Third, the government has to increase the level of payment, thereby rendering persons who receive the NBLI payment to enjoy minimum living standard. Finally, whether persons financially support other family numbers or not, the state has to be the first and major party in preventing poverty.

The purpose of this study was to explain the factors that effect on ego-identity of Pusan National University(PNU) freshmen. In order to achieve the above purpose 2,743 freshman class of 1988 were selected. Statistical methods applied were general descriptive statistics, Pearson's collelation method, multiple regression analysis. The statistical computations were done by SPSS. The results of this study are summarized as follows: 1. The personal and domestic factors that effect on ego-identity of PNU freshman class of 1988 are mother's attitude of rearing the adaptation confidence of the university life, religion, the participation of the social reality, the experience of the acquaintance with the other sex, the self-conceit and health. 2. The personality factors that effect on ego-identity of PNU freshman class of 1988 are the social introversion and the social responsibility. 3. The factors that effect on ego-identity of PNU freshman class of 1988 are the social introversion, the social responsibility, mother's attitude of rearing religion, the participation of the social reality, a sense of superiority, the experience of the acquaintance with the other sex, the adaptation confidence of the university life.

The study was to develop a Korean college student version of the Psychoeducational Intervention Program for unipolar depression originally developed by Lewinsohn et. al. (1982). In addition, the study was to find the effectiveness and any procedural problems for the application to the college students in unipolar depression. In order to achieve the above purposes, seven college students among volunteers were selected in terms of Beck Depression Inventory (BDI) and Depression scale of MMPI(MMPI-D). All the subjects scored above 70 points of T-score on MMPI-Depression scale, below 60 points of t-score on MMPI-Mania scale, and also above 16 points on BDI. The original program by Lewinsohn et. al. (1982) was translated and revised to seven session program for college students and also reconstructed the related materials which were workbooks and activity tasks. Examining the effectiveness of the program to the college students, pre- and post- tests of BDI and MMPI-D were given. The results showed that there were significant reduction of post- test scores of BDI and MMPI-D. Therefore, the program was confirmed to be effective for the college students in unipolar depression. The main procedural problems implementing the program was how to make students in depression actively follow and motivate in the procedures of the program.

ASEA-SKF 래들용 고알루미나 내화재의 용손성향

박홍채,이윤복,양태영,장윤식,오기동 釜山大學校生産技術硏究所 1997 生産技術硏究所論文集 Vol.53 No.-

ASEA-SKF 래들에 사용된 고알루미나 내화물의 광물 및 화학적 변화를 화학분석, 현미결관찰, X-선회절분석으로 조사하였다. 미사용 벽돌의 주요 광물상은 α-Al₂O₃, mullite, tridymite이었다. 가동면에서 SiO₂결정상이 소실되었으며 mullite와 α-Al₂O₃가 다소 감소하였고 2FeO·SiO₂와 hercynite, FeO, Cr₂O₃상이 생성되었다. 침식율은 강종에 따라 다소간 차이가 있었으며 용강 SF-45와 60분간 반응시켰을때 SK36벽돌의 침식율은 75.9%인 반면에 SK38벽돌의 침식율은 20.47%이었다. 대부분의 용손벽돌에서 가동면으로부터 내부로 감에 따라 열적 및 화학적 스폴링으로 인하여 미세균열이 존재하였다. Mineral and chemical changes of alumina refractories used in ASEA-SKF ladle were examined by chemical analysis, microscopy and X-ray diffraction method. Main minerals in unused high alumina runner bricks were α-Al₂O₃, mullite and tridymite. In working face of high alumina runner bricks, SiO₂phase was not observed, mullite and α-Al₂O₃phases more or less decreased. On the other hand, 2FeO·SiO₂, hercynite, FeO and Cr₂O₃phases were formed. Th corrosion of high alumina runner bricks showed different behavior by using various types of iron melts. Expecially, corrosivites of SK36 bricks and SK38 bricks, which immersed in SF-45 Iron melts for 60min, were 75.9% and 20.47%, respectively. Microcracks in high alumina runner bricks increased from the working face to the inside due to thermal and chemical spalling.
