Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

As the number of cars is rapidly increasing, we have to solve traffic jam. Therefore it is internationally developing IVHS(Intelligence Vehicle Highway System) to solve it. To extract the shortest path from road network, it need that digitized road network database construction, linked cost generation used road attribute and shortest path algorithm. In this paper, We extract twenty six intersections and roads between intersections from road network that extracts the central area of Chun-Chon city map with 1:25000 scale. And We make directed graph with these intersections which mapped nodes and these roads which mapped links. First, link cost be granted road length. Second, link cost be granted travel time of considering signal light at intersections. Shortest Path is extracted using link cost and appling Dijkstra algorithm.

반도체 집적 소자를 제작하기 위하여 감광제에 빛을 쪼여주게 되는데 이 때 감광제의 굴절률이 변하게 된다. 기존 시뮬레이션 방법에서는 굴절률중 허수에 해당하는 흡수 계수의 변화만 고려되었으나 우리는 실수 굴절률 변화도 고려된 시뮬레이션 방법을 개발하였다. 개발된 방법에 의해 실수 굴절률 변화가 노광 공정에 어떠한 영향을 끼치는지 swing curve와 측면각 등에 대해 탈 초점 및 에너지에 따른 선폭 변화에 대해 조사하였다. I-line과 193 ㎚용 감광제에 적용시켰으며 그 결과 실수 굴절률이 증가하면 선폭을 더 작게 조절할 수 있고 공정여유도도 크게 하지만 측면각은 작아지고 실수 굴절률이 감소하면 선폭은 커지고 공정여유도는 작아지지만 측면각이 증가하는 경향을 보인다. The refractive index of photoresist is changed during exposure of the lithography process. Conventional simulation considers the change of the imaginary refractive index only. We developed a new simulation tool that includes the change of the real refractive index. We investigated the effect of this change to the lithography process. The line width, defocus, energy, swing curve, and side wall angle are studied. We applied the tool to the I-line resist and 193 ㎚ resist. As the real refractive index increases the line width decreases and the process latitude increases, but the side wall angle decreases. As the real refractive index decreases the line width increases and the process latitude decreases, but the side wall angle increases.

The acute and subacute toxicity of New Woohwangchungsimwon(NWCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats(Sprague-Dawley, SPF) were injected intraperitoneally with dosages of 0, 540, 750, 1,070, 1,500 and 3,000 ㎎/㎏. Body weights were significantly decreased at 540 ㎎/㎏ dose group in both sexes and abnormal autopsy findings were founded in both sexes at all treated groups. Intraperitoneal LD_50 of NWCH was 812.3 ㎎/㎏ in male and 872.3 ㎎/㎏ in female rats. In the subacute toxicity study, NWCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800 and 2,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NWCH might be over 2,000 ㎎/㎏/day in this study.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

Blue light emitting PPV [poly (p-phenylene vinylene)] copolymers soluble in common organic solvents are synthesized and their structural and light emitting properties are studied. Copolymers show π-π* transition in UV-Vis. spectra and their λmax shift to shorter wavelength compare to that of monomers. The PL and absorption spectrum shows the symmetric vibration modes with muror images which means that copolymers are highly, aligned. The band gap energy of these copolymers are ~3.0 eV. By introducing aliphatic hydrocarbon group into polymer main chain, the stability of copolymers is increased and no significant effects of substituents are observed.

There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.

This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.

In order to make a functional jam containing garlic, sugar, acid and pectin were mixed with garlic and concentrated by heating the mixture under atmosphere or vacuum conditions. And changes of some physico-chemical properties of the garlic jam(i.e., color, textural properties, vitamin C) were investigated during storage at 30℃. It was found that lightness(L) was higher in sample of vacuum concentration than that in atmosphere concentration and redness(a) and yellowness(b) were higher in sample of atmosphere concentration. During the storage lightness was found to decrease for all samples with more drastic decrease in sample of atmosphere concentration where browning was more severely observed after 8 weeks of storage. In terms of textural properties, hardness, chewiness and gumminess were higher in sample of atmosphere concentration than that in vacuum concentration. And springiness and cohesiveness were higher in sample of vacuum concentration. Although sensory score for garlic jam found to be lower than that for the existing strawberry jam, the present garlic jam might have high marketability if considering its physiological value. 마늘을 이용한 기능성 잼을 제조하기 위하여 마늘에 당, 산, 펙틴을 첨가하고 평압과 감압에서 농축하여 마늘잼을 제조한 후 색도, 조직특성을 조사하고 30℃에서 저장하면서 색도, 조직의 변화, 비타민 C의 변화를 측정한 결과는 다음과 같다. 원료마늘의 일반성분은 수분 57.2%, 탄수화물 23.6%, 조단백 1.9%, 조지방 0.75%, 회분0.93%이었고 비타민 C는 8.4 mg/l00g이었다. 명도는 진공농축한 것이 평압농축한 것보다 높았고 적색도와 황색도는 평압의 것이 높았다. 저장기간에 따라 명도는 모두 감소하였으나 평압에서 농축한 것이 감압보다 크게 감소하였으며 갈변화가 저장 8주에는 심하게 나타났다. 마늘잼의 조직특성은 hardness, chewiness, gumminess는 평압농축이 감압농축에 비하여 높았고 springiness, cohesiveness는 평압농축이 낮았다. 마늘잼의 기호성은 딸기잼에 비하여 떨어지지만 기능성을 감안할 때 시장성이 매우 높을 것으로 판단한다.
