This study is phenomenological qualitative research about lived experience of recovering alcoholic homeless who had completed Therapeutic Community program. The meaning which is revealed through this study is as in the followed. First, Moving to recovering space. In Therapeutic Community, they have a turning point for new life and new connection with people who watch him carefully. Second, Physical recovery. They are no more lying down on the street. Analogy of Standing can be viewed as being most active in recovery. Third, Positioning on time flow. The recovering of time is represented by accepting past and present as well as looking ahead into the future. Fourth, Settling into network of a relation. They tried to reconnect with society by network of a relation. Their social place is located in a network, not a position. From this present study, the social work implications for the alcoholic homeless are deducted.

Objective Determine differences between faculty, residents, and nurses regarding night shift preparation, performance, recovery, and perception of emotional and physical health effects. Methods Survey study performed at an urban university medical center emergency department with an accredited residency program in emergency medicine. Results Forty-seven faculty, 37 residents, and 90 nurses completed the survey. There was no difference in use of physical sleep aids between groups, except nurses utilized blackout curtains more (69%) than residents (60%) and faculty (45%). Bedroom temperature preference was similar. The routine use of pharmacologic sleep aids differed: nurses and residents (both 38%) compared to faculty (13%). Residents routinely used melatonin more (79%) than did faculty (33%) and nurses (38%). Faculty preferred not to eat (45%), whereas residents (24%) preferred a full meal. The majority (>72%) in all groups drank coffee before their night shift and reported feeling tired despite their routine, with 4:00 a.m. as median nadir. Faculty reported a higher rate (41%) of falling asleep while driving compared to residents (14%) and nurses (32%), but the accident rate (3% to 6%) did not differ significantly. All had similar opinions regarding night shift-associated health effects. However, faculty reported lower level of satisfaction working night shifts, whereas nurses agreed less than the other groups regarding increased risk of drug and alcohol dependence. Conclusion Faculty, residents, and nurses shared many characteristics. Faculty tended to not use pharmacologic sleep aids, not eat before their shift, fall asleep at a higher rate while driving home, and enjoy night shift work less.

Tobacco smoking is a major risk factor of systemic health and also impairs oral health, which is related to development of oral cancers, periodontitis, delayed wound healing, tooth loss, failure of implant, etc. Aside from smoking, many other risk factors can be related to oral health and long-term effects of smoking on salivary flow and taste threshold are still in controversy. Authors considered dental students to be an appropriate group with good oral hygiene for a long-term study to reveal effects of smoking on oral health. This study was performed to compare smoking patterns and current oral health conditions between smokers and nonsmokers in dental students prior to long-term evaluation. 192 volunteers (85.7%) of 224 male dental students in Dankook University were evaluated through questionnaires and clinical examination in 2010. Questionnaires included smoking pattern, alcohol use, nicotine dependence, preventive care, psychological profile and clinical examinations comprised assessment of teeth or periodontal status, nicotine pigmentation, salivary flow, electrical taste thresholds and halitosis. From the study, (current) smokers were older, and drank more frequently with more alcohol intake compared to former smokers and nonsmokers(p<0.05). There was no significant difference among them in salivary flow rate, halitosis and electrical taste threshold. However, there was significant difference in DMFT rate, periodontal treatment need, nicotinic pigmentation between smokers and nonsmokers(p<0.05), irrespective of their levels of preventive care. The smokers in this study, who are young dental students with relatively shorter duration of smoking, less use of cigarettes and low level of nicotine dependence, did not reveal significant impairment of oral health. However, their oral health was found to be relatively impaired compared to nonsmokers', which suggests negative effect of smoking on the oral health and a need of smoking cessation.

This study was conducted to figure out characteristics of the children of problematic drinkers by reviewing the studies on those children reported in nursing studies in Korea and incorporating the results. The research method was integrated literature review, and for the study, eleven articles were selected by searching with key words such as 'problematic drinking', 'alcoholic', 'alcohol dependence', 'children', and 'nursing' in three research databases, spanning between 2000 and 2014. The research results are as follows: For the domestic nursing studies on the children of problematic drinkers, there were many descriptive research using survey method, requiring introduction of various research methods in order to know characteristics and lives of the children of problematic drinkers in depth. For main characteristics of the children of problematic drinkers, they have lower ability to cope with, many of them suffer from psychological and mental health problems, are very sensitive in interpersonal relationships with higher hostility. In addition, it is reported that the children of problematic drinkers are likely to have more problematic drinking, show higher depression and lower emotional perception and expression, social support, and social competence. Based on the results of this study, considering the fact that there are extremely few studies on the children of problematic drinkers, it requires more active studies and researches in nursing. Through the study with accurate results, it will contribute to nurses' capability in both clinical settings and local community as a guideline.

Objectives : In the psychiatry, structured interview is very important tool to be used in epidemiological or psychopharmacological studies. However, investigators often find that the administration of comprehensive diagnostic interviews is time-consuming and expensive to be used in clinical or research settings. Considering these points, Sheehan and his colleagues developed MINI (Mini International Neuropsychiatric Interview) to meet the need for a brief, reliable, and valid structured diagnostic interview for psychiatric disorders. The MINI has been translated into many languages and used in many countries. Therefore, we translated the MINI into Korean and determined its validity in this study. Methods : Twohundred seventy patients and normal subjects participated in the validation of the MINI versus an expert's professional opinion. Schizophrenia and other psychotic disorders, mood disorders including major depressive disorder and bipolar disorder, anxiety disorders including panic and other phobic disorders, and alcohol dependence were included in this study. The validity was obtained by examination whether MINI based diagnoses were compatible with diagnoses by expert psychiatrists. Results : The range of Kappa values was 0.22 (somatoform disorder) to 0.93 (bipolar disorder - past). Overall agreement between MINI and expert's diagnoses were good. The Kappa values for anxiety disorders seemed to be higher than those for other disorders. Conclusion : The MINI Korean version has the good validity. It also has potential applications as a diagnostic tool for psychiatric disorders.

Purpose : This study was conducted to survey the preliminary data on risk behaviors and to identify the factors that prevent risk-behaviors in late adolescence. Methods : Freshmen(n=1,297) beginning the first semester in Korea University, Seoul, Korea completed self-administered risk behavior questionnaires, comprising 5 domains : demographics, smoking, drinking, drug abuse and sexual behavior. Results : The rate of smoking experience was higher in people having friends who smoke and the predictors of transition to current smoking were male gender, urban residence, friends' smoking, and nicotine dependence. The rate of high risk drinking was higher among students who are male and who had experience of heavy episodic drinking. The study group showed a low prevalence of narcotic users, but two-thirds of students could get medicine easily without prescriptions. The prevalence of sexual experience was 6.5 percent, and the sexual education was not a predictor of contraceptive behavior. The prevalence of homosexuality was 1.6 percent, and the rate of mostly heterosexuality was higher in female students. Conclusion : The main targets of youth health education should be campaigns aimed at atcessation of reinforcing risk behaviors and the development of a surveillance system for the prevention of chronic disease. These results can be used to find risk factors of health-risk behaviors among late adolescents.

Background : In spite of the worldwide relevance of obsessive-compulsive disorder Ed-highlight : Unclear. Perhaps consider changing word choice. (OCD), there are considerable differences in prevalence, sex ratio, comorbidity patterns, and sociodemographic correlates. Data on subclinical OCD have been sparse to date. Methods : Data stemmed from the Korea Epidemiologic Catchment Area (KECA) study which had been carried out from April to December 2001. Korean versions of DSM-IV adapted Composite International Diagnostic Interview were administered to a representative sample of 6275 persons aged 18-64 living in the community. DSM-IV based criteria for subclinical OCD were applied. Results : The lifetime prevalence rates for OCD and subclinical OCD were 0.8% and 6.6%, respectively. In both OCD and subclinical OCD, the rates for males and females were not statistically different. OCD was demonstrated to be associated with depressive disorder, bipolar disorder, social phobia, generalized anxiety disorder, and alcohol and nicotine dependence. Additionally, subclinical OCD was associated with posttraumatic stress and somatoform disorders. Comorbidity rates in subclinical OCD were lower than those in OCD. Conclusions : The lifetime prevalence rate for OCD was less than 1% in the Korean general population. Age distribution and comorbidity patterns suggest that subclinical OCD represents a broad and heterogeneous syndrome and not simply a milder form of OCD.

The sensing and electrical characteristics of $WO_{3}$-based n-type semiconductor gas sensors are investigated. In normal air condition, $TiO_{2}$(4 wt. %)-doped $WO_{3}$-based sensor fabricated without any binder shows the grain boundary ( GB ) potential barrier height of 0.26 V. Sensors fabricated with alumina, PVA and silica sol binders show 0.17, 0.22 and 0.26 V of GB potential barrier height, respectively. In the ambience of 120 ppm $NO_{x}$ concentration, the GB potential barrier height of the sensor fablicated without binder is increased to 0.59 V. The sensors were fabricated with alumina, PVA, silica sol binders show 0.43, 0.66 and 0.52 V of potential barrier, respectively. Thus the variation of the potential barrier at GB is largest in the sensor fabricated with the PVA binder. This is found to be the main reason why the sensor fabricated with the PVA binder shows the best sensitivity. It is also found that the decrease of sensitivity at a temperature higher than the optimum operation temperature is due to the temperature dependence of the sensor resistance in normal air condition rather than the desorption of the adsorbed $NO_{x}$ gas particles. In the ambience of 250 ppm CO concentration, the GB potential barrier heights of the sensors fabricated without binder and with PVA binder are about 0.2 V showing negligible change compared to the case of normal air ambience. This fact indicates that these sensors are good candidates for the selective detection of $NO_{x}$ gas in the mixture of CO and $NO_{x}$ gases.

The thermal and optical properties of poly {1-(cholesteryloxycarbonylalkanoyloxy) ethylene}s (PCALEn, n=2$\sim$8,10, the number of methylene units in the spacer) were investigated. All of the homologues formed monotropic cholesteric phases with left-handed helical structures. PCALEn with n=2 or 10, in constrast with PCALEn with $3{\leq}n{\leq}8$, did not display reflection colors over the full cholesteric range, suggesting that the helical twisting power of the cholesteryl group highly depends on the length of the spacer connecting the cholesteryl group to the polyethylene chain. The glass transition temperatures decreased with increasing n. The isotropic-cholesteric phase transition temperatures decreased with increasing n up to 7 and showed an odd-even effect. However it became almost constant when n is more than 7. This behavior is rationalized in terms of the change in the average shape of the side chain on varing the parity of the spacer. This rationalization also accounts for the observed variation of the entropy gain for the clearing transition. The thermal stability and degree of order in the mesophase and the temperature dependence of the optical pitch observed for PCALEn were significantly different from those reported for cellulose tri(cholesteryloxycarbonyl)alkanoates. The results were discussed in terms of the differences in the chemical structure and flexibility of main chain and the number of the mesogenic units per repeating unit.

The purpose of this study was to investigate families' responses and attitudes and the experiences of Korean LGBT individuals after revealing their sexual identity and sexual orientation and to determine how families' attitudes affected the mental health of these individuals. For this purpose, in-depth interviews were performed with 12 male and female LGBT participants, ranging from 19-30 years of age, who resided in Seoul and metropolitan areas, and reported coming out to or being outed by their families. One-to-one interviews were carried out using semi-structured questions, and the data from the interviews were analyzed using consensual qualitative research (CQR). Most of the families had very negative responses and attitudes to the participants coming out and exhibited rejection or avoidant attitudes; only a few of the families responded with receptive attitudes. As a result, the LGBT participants reacted with friction and coping behaviors, such as persuasion, participation in professional counseling, abandonment or avoidance, and running away from home. Most of the effects of the families' attitudes on the participants were negative psychological effects, such as anger, sadness, a sense of alienation, depression, anxiety, fear, trauma, helplessness, lowered self-esteem, alcohol dependence, and suicidal ideation and attempt, while receptive attitudes provided a sense of stability. For all participants, they reported that they were more likely to be hurt by their families' negative attitudes than by social attitudes. This study is significant because it provides framework for specifying families' attitudes and LGBT individuals' experiences after coming out in Korean society. It also outlines LGBT individuals' coping behaviors, psychological difficulties, and the process of coming out and provides suggestions for individuals to overcome. The results are expected to help counselors create practical strategies to better understand LGBT individuals and the psychological difficulties they may experience and provide proper interventions while counseling both the individual and the family.
