Background and Objectives : Cigarette smoking is a major factor and the most modifiable risk factor for atherosclerosis. Endothelial dysfunction is an early event in atherosclerosis, before the structural change of the systemic arteries. We hypothesized that endothelial dysfunction might be present in the systemic arteries of young adult smokers and that this might be dose-dependent phenomenon. Therefore, we try to certify that smoking is associated with endothelial dysfunction in healthy young adults without other risk factor of atherosclerosis. Subjects and Methods : we studied noninvasively 29 subjects aged 3 to 4 decades without other risk factor of atherosclerosis, they were composed of the two groups, current smokers(n=15) and nonsmokers(n=14). Smoking history varied from 3 to 20 pack years. Using high-resolution ultrasound, vessel diameter and mean flow rate were measured at rest, during reactive hyperemia(with flow-mediated endothelium-dependent dilation), and after sublingual nitroglycerin(NG-induced endothelium-independent vasodilation). Result : Flow mediated endothelium dependent dilation was observed in the control subjects (9.4±3.44%) but was impaired in the smokers(5.8±2.51%)(p=0.004). NG-induced endothelium independent dilation is no difference in all subjects. Conclusion : Cigarette smoking is associated with endothelial dysfunction in healthy young adults.

Objectives : The purpose of this study is to assess the psychometric properties and to investigate factor structure of the Korean version of the Young ADHD Questionnaire-Self-Report (K-YAQ-S) and the Young ADHD Questionnaire-Informant-Report(K-YAQ-I). Methods : 269 normal college students completed the K-YAQ-S and the Lee Ji-Yeon's adult ADHD scale (1996). 213 in-formants of the subjects completed the K-YAQ-I. Results : The K-YAQ-S and the K-YAQ-I had good internal consistency (Cronbach's =.957, .965). An ADHD symptomatology and emotional problem subscales of the K-YAQ-S showed strong correlation with the Lee Ji-Yeon's adult ADHD scale. The delinquency and social functioning subscales of the K-YAQ-S and all subscales of the K-YAQ-I correlated significantly but were relatively lower. An exploratory factor analysis showed that the K-YAQ-S revealed 4 factors (ADHD symptomatology, emotional problems, delinquency, social functioning) and the K-YAQ-I being composed of 3 factors (ADHD symptomatology/aggressive behavior, emotional problem/social functioning, illegal act). Conclusion : These results suggest that the K-YAQ-S and the K-YAQ-I rating scale is a reliable and a valid test. These scales would be useful in diagnostic evaluation and in measuring the treatment effect for ADHD adult.

본 연구는 청소년의 성문제를 위한 목회상담적 접근을 시도했다. 먼저 청소년의 성의식과 성문제를 연구한 논문 및 자료들을 선행 연구했다. 그런 다음에 청소년의 성의식을 살펴보았고 청소년의 성문제를 성욕증가, 자위행위, 혼전성관계, 데이트, 사회학습적 접근 등의 5가지로 나누어서 연구했다. 청소년의 성문제 5가지 중에서 핵심이 되는 혼전성관계를 집중해서 살펴보았고 혼전성관계의 원인과 논쟁을 다루었고 혼전성관계에 관한 성경적인 관점을 연구했다. 그런 다음에 청소년 성문제를 위한 목회상담적 대안을 10가지로 제시했다. 본 연구의 10가지 대안은 오성춘의 청소년신앙교육의 목표 5가지 항목과 McDowell과 Hostetler의 청소년 상담자의 자질 8가지에 근거해서 작성했다. 청소년성문제를 문제를 위한 10가지 목회상담적 대안은 다음과 같다. ① 청소년의 이야기에 경청하라 ② 성교육의 현장으로 가정과 부모를 활용해라 ③ 청소년의 성교육을 위해 교회의 역할을 실천하라 ④ 청소년들의 바른 신앙과 가치관 확립을 도와라 ⑤ 청소년들의 삶을 섹스 외에 더 좋은 것으로 채우도록 격려하라 ⑥ 청소년성교육을 담당할 지도자를 육성하라 ⑦ 성문제에 실패한 청소년을 적극적으로 수용하라 ⑧ 성문제에 대한 타협적인 자세를 배격하라 ⑨ 성적만족에 관한 체감의 법칙을 숙지시켜라 ⑩ 청소년들에게 성적인 금욕을 선택하도록 권면하라. This paper focussed on the role of pastoral counseling for adolescents’ sexual problems. Firstly, this paper researched several previous studies on sexuality perception and problems among the youth. This paper illustrated five items including increase of sexual desire, masturbation, premarital sex, date, social learning theory as adolescents’ sexual problems. This paper furthermore concentrated its study on premarital sex as the most concerning issue among the five items. This paper illustrated 10 approaches as the role of pastoral counseling for the adolescents’ sexual problems. The ten items were made on the basis of Oh Sung Choon’s five aims of Christian education for the young and McDowell and Hostetler’s seven qualities of Christian counselors for the young. The ten approaches are as follows. ① Listen to carefully adolescents’ hurt story ② Utilize family and parents of the adolescents as a bridge of sexual counseling ③ Put the function of church for juvenile sex education into practice ④ Build up adolescents’ right belief system and value system ⑤ Encourage up adolescents to fill up their lives with better valuable things besides sex ⑥ Bring up specialists of the adolescents’ sex counseling ⑦ Accept positively the adolescents with failed experiences in sexual problems ⑧ Resist a compromising attitude against sound Christian sexual ethics ⑨ Teach adolescents the law of diminishing in sexual satisfaction ⑩ Admonish desirable attitude and behavior toward sex.

The purpose of the present study was to investigate the relationship between isokinetic muscle function and muscle cross-sectional area (CSA). Twelve women participated in the present study, divided young (n=6, 23.7±1.9 year) and elderly women (n=6, 60.3±6.8 year). Isokinetic strength (power, strength, endurance) and CSA (psoas major and thigh muscles) measured with dynamometer and computerized tomograph, respectively. Cross-sectional area of psoas major muscle in elderly group revealed markedly smaller than in young group, but thigh muscle was not the case. Muscle CSA in young women correlated between power and endurance and psoas major muscle, as well as between muscle strength and CSA of thigh muscle. But no correlation occurred between strength and cross sectional area, except endurance which was highly correlated between CSA and endurance. In conclusion, aging decreases muscle function and CSA. Partially muscle strength correlated with muscle CSA in young women, but no correlation occurred in elderly women. Further study needed to elucidate the exact mechanism related to aging muscle with muscle density and neuromuscular function.

Previously, Gum Metal (Ti-24(Nb + Ta + V)-(Zr, Hf)-O (at%)) exhibiting an ultralow Young`s modulus, ultrahigh strength and super elasticity was developed by Saito et al., who proposed that three electronic magic numbers, an average electron/atom (e/a) ratio of 4.24, an average bond order (Bo) of about 2.87, and an average “d” electron-orbital energy level (Md) of about 2.45 eV, should be satisfied simultaneously to obtain such “super” properties. The purpose of this study was to find new alloy systems possessing those properties and to examine the effect of beta equivalent content ([Mo]eq) on Young`s moduli of new alloys having the same three electronic numbers mentioned above. It was found that not only three electronic numbers but also [Mo]eq should be considered to obtain a similar Young`s modulus and hardness with respect to the Gum Metal.

This study was performed to investigate the effect of olive oil diet on the immune response in ICR male mice. Experimental diets of 4 groups were fed ad libitum to the ICR male mice for 27 days. The results of this study were summarized as followings: 1. 10% Olive oil diet group as compared with the control diet group significantly decreased liver weight rate but significantly increased hemagglutination titer (HA), Arthus reaction, delayed type hypersensitivity reaction (DTH), rosette forming cell (RFC), and phagocyte activity. 2. 20% Olive oil diet group as compared with the control diet group significantly increased body weight gain, liver weight rate, and HA but significantly decreased Arthus reaction, DTH, RFC, phagocyte activity, and peripheral circulating white blood cell (WBC). 3. 30% Olive oil diet group as compared with the control diet group significantly increased liver weight rate but significantly decreased body weight gain, Arthus reaction, plaque forming cell (PFC), DTH, RFC, phagocyte activity, and WBC. The results showed that the increase of olive oil doses significantly decreased humoral and cellular immune responses, phagocyte activity, and WBC.

The characteristics of H₂ production from livestock wastewater were investigated through an anaerobic acid forming process using Clostridium beijerinckii and the photosynthetic process using Rhodobacter sphaeroides. The submerged separation membrane was installed in the acid forming reactor. The photosynthetic process is composed of two reactors(photosynthetic reactor 1 and photosynthetic reactor 2) which is connected continually. The removal rate of COD and the production of volatile fatty acid(VFA) in the acid forming process were approximately 50% and 1000㎎/ L, respectively. The 70% of COD in the effluent of acid forming process was removed through the photosynthetic process. The production of H₂ in the photosynthetic reactor 1 and 2 was 50 and 25mLH₂/gVFA_(COD), respectively. The values of Y in acid forming reactor, photosynthetic reactor 1 and 2 was 0.2263, 0.0601 and 0.0393, respectively. The acetic acid and butyric acid produced in acid forming process were converted to H₂ by photosynthetic bacteria.

The Korean hemorrhagic fever (KHF) is an acute febrile disease with characteristic of fever, bleeding tendency, and renal failure. There are many complications of Korean hemorrhagic fever such as infection, anemia, internal bleeding, hypopituitarism, respiratory, and neurologic complication. A few cases were reported on acute pancreatitis with hemorrhagic fever abroad, but there was no case about Korean hemorrhagic fever with acute pancreatitis in this country. We experienced a case of Korean hemorrhagic fever associated with suspected acute pancreatits. With review of articles, we report a case of 51 year-old woman with KHF, where acute pancreatitis developed during management, (Korean J Infect Dis 33:376∼379, 2001)
