In spite of the seriousness of smoking harm has been developed these days. the increase of national smoking rate and that the people in the twenties are especially leading the rise of national smoking rate is an important issue of national health. Smoking of the university students can occur health problem and cause loss of manpower and expenses in their social activity period. So then the actual state for prevention of smoking and development of a program to prohibit smoking has to be seized urgently and starting with the study of the realities of university students, the effort to find a related fluent of smoking has to be studied. Related to this, the purpose of this study is to seize the general characteristics of smoking university students and to find out the relationship between perceived stress and smoking status among smoking university students. In addition, by collating the relationship between perceived stress and smoking status among smoking university students we have the purpose to furnish the basal data of stress care, the best way to cope with stress through group training and the plan for nursing implementation to decrease the smoking rate. For this study, a survey was conducted for 204 smoking university students of 13 universities in Seoul from 9th of May to 16th of May, 2003. The collected data was analyzed by t-test, Pearson Correlation and ANOVA in the statistical packages SPSS/PC. Major findings of this study are as follows; 1. Of the 204 respondents 85.4% of them were male and 14.6% of them were female. The average age of the sample was 23.19 years old and 41.8% of them were in senior, 21.4% in junior, 16.9% in sophomore, 19.9% in freshman grade. The major motivation to start smoking was 'because of curiosity'(33.8%) and the first smoking experience was at 'senior high school' (41.9%) and at 'college' (41.9%). 2 The highest scored stress factor of smoking university students were stresses about school work. 3. 72.7% had experience to quit smoking at least one or more times. Most of the reason to keep on smoking was 'short will to quit'(51.0%) and the smoking place was usually at 'school' (41.4%). Most respondents for the number ofsmoking friends were '5 people and above' (73.2%). 4. There was a negative relationship between the general characteristics and the entire perceived stress, however, there was a positive relationship between the general characteristics and the perceived stress in 4 categories which is 'sex distinction', 'major of study', 'residence form' and' inmate'. 5. There was a negative relationship between the general characteristics and the entire smoking status, however, there was a positive relationship between the general characteristics and the smoking status in 2 categories which is 'presence of hobby' and 'number of smoking friends'. 6. There was a negative relationship between the perceived stress and the smoking status. Through this study we have seized the relationship between the general characteristics, perceived stress and the smoking status of smoking university students. There was a positive relationship between some of the general characteristics with the perceived stress and the smoking status of smoking university students. Also there was a negative relationship between the perceived stress and the smoking status.

本 硏究는 濟州地域의 冬季 장미 切花裁培를 위한 技術開發의 側面에서 栽培的 品種選拔을 위하여 露地裁培에 대한 可能性을 檢定하며, 土壤과 비배관리를 위한 基礎資料와 組織培養技術을 利用한 優良苗生産技術을 確立하기 위하여 修行하였던바 얻어진 結果는 다음과 같다. 晝夜間의 溫度變化가 심한 環境下에서도 잘適應했던 品種은 'Innocencia'와 'Madelon'이었다. 화경장은 無加溫 비닐하우스가 加溫 유리온실보다 좋았으며, 切花量은 약간 적었지만 濟州道의 西歸浦 地域에서 장미의 冬季 生産을 위한 無加溫 비닐하우스 栽培도 可能한 것으로 나타났다. 加溫과 輔光處理는 開花日數를 10-15일 가량 앞당겼으며 花質과 採花量도 向上시켰지만, 經濟的인 側面에서 볼 때 비닐하우스 無加溫 栽培도 비교적 良好한 結果를 보였다. 共試品種中 無加溫 비닐하우스 輔光栽培에 適合한 轢으로는 'Lorena', 'Dallas', 'Golden Madelion', 그리고 'Carl-red'等 이었다. 장미재배 土壤의 物理性은 孔隙率이 크기 때문에 배수성과 통기성이 장미재배에 적절하였으며, 재배 기간동안 유리온실 토양의 pH, 置換性 Ca, Mg 및 K, 有效燐酸의 함량은 비닐과 露土 토양에 비하여 높게 유지되었다. 不定芽 發生에 대한 基本 배지로는 MS배지 보다 WPM배지가 共試된 品種 모두 월등한 結果를 보였다. 生長點 培養時 0.1-1.0mg/l의 NAA와 2.5-5.0mg/l의 BA 混用處理가 苗의 生産과 生體重 向上에 좋은 結果를 나타냈다. 幼苗의 發根과 根數, 根長 그리고 活着率 모두 1㎖/l IBA處理보다 活性炭 2g/l添加 處理에서 良好하였다. The purpose of this study is to extract useful information for selecting a suitable variety of cultivation for cut flowers of rose. To meet this purpose three different ways of cultivation, such as non-heated and heated cultivations in vinyl house, and outdoor cultivation, were tested in terms of developing cultivation technique for cut flowers of rose during winter period in Cheju island. In addition, the research attempts to obtain basic idea for soil and culture condition and to develop production technique for a superior plantlet by using the technique of tissue culture. After analyzing the results we have reached the following conclusions: 1. 'Inocenia' and 'Madelon' were the most adaptable varieties under the wide temperture changes during day and night. 2. For the flower stem length, the non-heated vinyl house was preferred to the heated glasshouse. 3. It was found that the non-heated vinyl house is possible during winter period in Seogwipo city area. 4. The treatments of heating and supplemental lighting allowed not only to push about 10 to 15 days ahead of the flowering time but also to improve the quality and the amount of flowers. In terms of the economy, however, the treatments of non-heating and supplemental lighting might be preferrable to the one just described. 5. Among the tested cultivars, 'Lorena', 'Madelon', 'Dallas', 'Golden Madelion' and 'Carl-red' were suitable for the cultivation of non-heating and supplemental lighting. 6. Physical properties of the soil in the treatments were suitable for house culture of cut-rose, and pH, available phosphorus, exchangeable Ca, Mg, and K and nitrate concentration of soil in glasshouse were higher than vinylhouse and open field. 7. The results from the test of basic media about the generation of adventitious rooting showed that the WPM medium is better than the MS medium for tested six cultivars. 8. It was identified that the application of 0.1-1.0 mg/l NAA and 2.5-5.0 mg/l BA at the time of meristem culture came out with likable outcomes for plantlet production and improvement of fresh weight. Treatment of 2 g/l activated charcoal is better than 1 mg/l IBA for rooting, root number, root length, and rooting percentage of a plantlet.

The objective of this study was to investigate the efficiency of nicotinic acid on sperm cryosurvival and fertilizationability in frozen-thawed boar semen. Boar semen was collected by glove-hand method and was frozen using freezingsolution treated to 0, 5, 10 and 20 mM of nicotinic acid. The frozen sperm for sperm characteristic analysis was thawedsuch as viability, acrosome reaction, and mitochondrial integrity. The frozen-thawed sperm was estimated by SYBR14/PIdouble staining for viability, FITC-PNA/PI double staining for acrosome reaction and Rhodamine123/PI double stainingfor mitochondrial integrity using a flow cytometry. The embryo was estimated in vitro development and DCFDAstaining for reactive oxygen species assessment. As results, frozen-thawed sperm viability was significantly higher in5 and 10 mM (61.1 ± 1.5%, 64.7 ± 2.0%) of nicotinic acid than other groups (0 mM, 52.1 ± 2.3%; 20 mM, 47.8± 5.1%, P<0.05). The live sperm with acrosome reaction was significantly higher in 5 and 10 mM of nicotinic acid(26.1 ± 1.8%, 24.9 ± 1.5%) than other groups (0 mM, 35.3 ± 0.8%; 20 mM, 36.5 ± 1.9%, P<0.05). The live spermwith mitochondrial integrity was significantly higher in 5 and 10 mM (84.2 ± 3.6%, 88.4 ± 2.3%) of nicotinic acidthan other groups (0 mM, 77.3 ± 4.4%; 20 mM, 73.3 ± 3.6%, P<0.05). Blastocyst rate of in vitro development wassignificantly higher in 10 mM (17.0 ± 1.3%) of nicotinic acid than other groups (0 mM, 9.4 ± 0.5%; 5mM, 12.6 ±0.8%; 20 mM, 5.0 ± 1.0%, P<0.05). Moreover, total cell number was higher in 5 and 10 mM (53.6 ± 2.9%, 57.9± 2.8%) of nicotinic acid than other groups (0 mM, 41.0 ± 1.4%; 20 mM, 23.2 ± 2.8%, P<0.05). Hydrogen peroxidein embryos was lower in 5 mM nicotinic acid (0.7 ± 0.1%) than other groups (0 mM, 1.0 ± 0.1%; 10mM, 0.9 ±0.0%; 20 mM, 1.4 ± 1.0%, P<0.05). In conclusion, nicotinic acid-treated semen improves cryosurvival and qualityof spermatozoa. Also, the fertilized oocytes with nicotinic acid improve quality of embryo and blastocyst formation

Helicobacter pylori infection is highly prevalent, as high as 2/3 of whole population infected, in Korea. H. pylori infection initiates inflammation by induction of interleukin-8 through type IV secretion of CagA. It was recently suggested that induction failure of IL-8 is not associated with defect in cag PAI but associated with cagE locus diversity. This study was designed to investigate ability of 11-8 in-duction according to sequence variation within the cagE gene, cagA TP motifs and vacA m-types in vitro study using AGS cell-line, and to evaluate its association with different clinical outcome. Seventy-four H. pylori stains were isolated from 23 patients with gastric cancer (Ca), 24 subjects with gastritis (G) and 27 patients with duodenal ulcer (Du) in Kangnam St. Mary's Hospital, Seoul, Korea. cagE gene diversity was confirmed by the PCR-RFLP methods with MboI/NlaIII and tyrosine phosphate motifs (TPMs) of cagA was determined TPM-A and C by using DdeI/Tsp5091 restriction enzyme and TPM-B was determend by Real time PCR the method of Owen et al. and IL-8 was measured by ELISA assay. IL-8 activity was positively detected in 59 among 74 strains $(79.7\%)$. IL-8 secretion was significantly increased in MboI A and MboI B type compared to MboI C type and in MboI/NlaIII A-C and B-C type than C-C type. 1L-8 activity was not associated with either the number or composition of cagA tyrosine phosphorylation motifs and vacA m-type. There was no significant difference in IL-8 activity among patient groups. cagE gene diversity is thought to be mainly associated with the induction of IL-8 in H. pylori infection. 한국에서 분리한 Helicobacter pylori 균주가 위암 세포주에서 IL-8를 유도하는 유도능을 관찰하고자 하였으며, 특히 4형 분비구조의 주요 구성체인 cagE 유전자의 다형성에 따라 IL-8 유도능의 차이 및 각 질환에서 분리한 균주에서의 차이가 있는지 검토하고자 하였다. 강남성모병원 내시경검사를 받은 환자들 중 H. pylori 감염 양성으로 확인된 위암 23명 $(31.0\%)$, 위염 24명$(32.6\%)$, 십이지장궤양27명$(36.4\%)$ 총 74명을 대상으로 하여 H. pylori를 분리한 후 PCR-RFLP방법을 이용하여 cagE 다형성을 확인하였으며, PCR 및 Real-time PCR을 이용하여 ragA TPMs를 결정하였다, 또한 분리된 균주를 위암세포주에 감염시켜 상등액을 취하여 ELISA방법으로 IL-8을 정량화 하였다. 전체 74개의 분리 균주 중 59개의 균주$(79.7\%)$에서 IL-8 유도능이 있는 것으로 확인되었으며, cagE 다형성 중에서 가장 높은 빈도로 관찰되는 형태는 MboI/NlaIII B-C, A-C 및 C-C 타입 이었으며, 이중 A-C와 B-C 형태가 C-C 형태에 비해 유의적으로 높은 IL-8 유도능을 나타냈다. 그러나 cagA TPMs의 분류 및 vacA m-아형 분류와 IL-8 유도능과는 연관성이 없었다. 비록 본 연구에서 cagE 다형성과 IL-8 유도능과 아주 밀접한 연관성이 나타나지는 않았지만 vacA m-아형이나 cagA TPMs 보다는 cagE 다형성이 IL-8 유도능과 연관성이 클 것으로 생각된다.

Objectives : Diffusion tensor imaging (DTI) is a new technique that can be used to visualize and measure the diffusion of water in brain tissue. It is particularly useful for evaluating white matter abnormalities. In this paper, we investigated the neuropathology of the corpus callosum in patients with schizophrenia through the new methods, diffusion tensor imaging. Methods : Diffuse tensor imaging was performed in 19 schizophrenic patients and 26 healthy controls. One complementary measure, fractional anisotropy (FA), which is considered to be sensitive indices of axonal integrity, was obtained from regions of interest in the five areas of the corpus callosum. Neuropsychological measurement also underwent for measurement of frontal lobe function in two groups. Results : There were no significant differences of FA in the DTI measures for either the schizophrenic patients compared with controls. FA was significantly decreased in women compared with men. Neuropsychological measurements such as Wisconsin card sorting test were correlated with FA of patients with schizophrenia. Conclusion : FA measures revealed no differences between schizophrenia and controls. The findings suggest that the structural integrity of white matter in patient with schizophrenia was not disrupted. The results are discussed in relation to previous studies reporting positive and negative findings. It is concluded that further studies using DTI in larger samples, improved and standardized methods of data acquisition and analysis are needed.

오인근,박은혜,양규호,오종석 전남대학교 치의학연구소 2003 구강과학 Vol.15 No.1

Fusobacterium nucleatum, one of the bacteria causing halitosis, produces the volatile sulfur compounds (VSC) such as H2S in the media containing sulfur components, and forms FeS by binding with iron component. The various factors of oral cavity affect the concentration of sulfur compounds produced by Fusobacterium nucleatum. In this study, the effect of nutrients and pH on the production of sulfur compounds by Fusobacterium nucleatum was studied with the following results; 1. The optical density of broth was increased to 0.817±0.032 and 1.297±0.024 by adding 1.0% sodium thiosulfate and 0.05% L-cysteine hydrochloride in the media, respectively. 2. Though the optical density of broth was 0.799 ± 0.032 by adding volatile sulfur compounds (VSC) only in the media, it was increased to 1.775±0.003 and 1.648±0.022 by adding xylitol combined with glucose and fructose, respectively. 3. The concentration of VSC was above 20,000 ppb in the media above pH 5.5. The optical density of broth was still high in the media with L-cysteine hydrochloride of higher concentration, being low in the media of lower pH. 4. The concentration of VSC was high when there was distilled water or saline solution on the media, and their amount was small. These results suggest that the production of sulfur compounds by Fusobacterium nucleatum is inhibited by xylitol and acid.

오인호(OH, In-Ho),박해완(Park, Hae-Wan) 한국체육과학회 2014 한국체육과학회지 Vol.23 No.5

This study, through in-depth interview, tried to do eco-feministic analysis on striking of female taegwondo players within a group. Research subjects were two female players and two male players in male and female taegwondo teams. First, the meaning of striking of female taegwondo players proved to be understood differently by male and female players. It was found that males got the negative image of striking of female taegwondo players. It is impressive that in a male-dominant taegwondo group, males rather than females got the negative perceptions on striking of female taegwondo players. Second, the real cases of striking of female taegwondo players are as follows. When female players were struck not by a senior member, but by a taegwondo leader, they tended to rationalize it as ‘it was my fault’, or ‘I deserve it’. And, the striking of female taegwondo players by a senior member was analyzed with metaphor of step-by-step process of nature destruction in the ecological perspective. Third, eco-feminism of female striking in the view of Nietzsche’s thought and Faucault’s discourse explain the female ‘gender’ as ‘Ubermensch’ to overcome. That is, ‘Ubermensch’ means a new female transcendental class to ‘overcome’ current eco-feministic situation. In addition, through Faucault, ecological power is explained, and females are perceived as an existence of ‘Ubermensch’ who have to escape from power.

Purpose of this study was to explore the meanings and nature of the lived socialization experience of the diploma nursing students. Method of this study was adopted the hermeneutic phenomenological human science approach developed by van Manen. The participants for this study were 8 diploma students, between the age of 23 and 35, who were healthy without any particular diseases. The 8 diploma students who had agreed to participate in this research were interviewed by the researchers under a private and comfortable environment. In collecting data for this study, in-depth personal interviews, transcriptions and observations were made by the researchers for 20days from January 22nd to February 15th, 2007. During the personal interviews the semi-structured questions were asked to the diploma nursing students to speak freely about the 'lived socialization experience' and the interviews were conducted three or four times per student for 50 to 120 minutes. Collected data were analyzed by hermeneutic phenomenological way of study that was developed by van Manen. Results were as follows. The six essential themes of the lived socialization experience of the diploma nursing students were found through this study 〈Mystery of the human body〉, 〈Too heavy a burden of study〉, 〈Keen competition〉, 〈A critical situation〉, 〈Support〉, 〈Becoming matured〉. Through the study, it was found that the diploma students consider the nursing science as a process of offering care to the patients with love, while acquiring knowledge of the academic and emotional personality. Conclusion: Studying the nursing science, indeed, means facing a desperate situation in which one has to struggle to survive in fierce competition within limited time. However, the students can stand all the hardships due to the hope for the future and the definite goals. Ultimately, they become mature by enhancing their understanding toward others. This study suggests visions and possibilities of the nursing profession by comprehending the meanings and nature of the lived socialization experience of the diploma nursing students.
