Purpose: The purpose of this study was to provide the basic data for university students to develop program for achieving successful developmental task. Method: The subjects involved this study were 462 1-4th grade university students located at Kangwon-Do & Chungchung-Do. Data were measured using Global assessment of recent stress scale, CES-D and Self-esteem scale. Data were analyzed using SPSS WIN 17.0 program that included mean, standard deviation, ANOVA, Sheffe test and Pearson correlation coefficients. Results: 1) The mean score of the degree of perceived stress was 4.17(${\pm}1.43$), depression was .92(${\pm}.47$), and self esteem was 2.89(${\pm}.48$). 2) There were significant differences in the degree of stress according to gender(t=2.03, p=.043), level of living(F=3.55, p=.029). Likewise, there were significant differences in the degree of depression according to gender(t=3.35, p=.001), age(t=2.15, p=.032), level of living(F=3.38, p=.035) and in the degree of self-esteem there were significant difference according to gender(t=3.64, p<.001), age(t=2.81, p=.005), participation of regular meeting or not(t=3.14, p=.002), frequency of alcohol drinking(F=5.59, p=.004), onset age of alcohol drinking(t=2.43, p=.016). 4) There was a significant relationship between stress and depression(r=.556, p<.001), self-esteem (r=-.423, p<.001). Also, there was a significant relationship between depression and self esteem(r=-.667, p<.001). Conclusions: Nursing interventions and educational programs which can help the students to accomplish the developmental tasks required.

Objectives: In an effort to examine the distribution of THMs (Trihalomethane) generated from chlorine disinfection by the drinking water treatment plants located on the east coast region of Gangwon-do, this study surveyed the distribution and concentrations of each component of THMs twice per month for 5 years from 2008 to 2012. Fluctuation pattern in the seasonal generation amount was identified. In addition, the correlation between the concentration of organic substances in water and THMs was assessed, along with stability of purified water quality supplied by the water treatment plants on the east coast by analyzing the composition ratio of each component that constitutes THMs and the detection frequency. Method: The research was done on purified water supplied by 29 water treatment plants in 7 cities and counties (Goseong-gun, Sokcho-si, Yangyang-gun, Gangneung-si, Donghae-si, Samcheok-si, Taebaek-si) located in Gangwon-do on the east coast. Water samples were collected twice a month from 2008 to 2012 and were investigate for chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform, based on analysis through Purge-Trap (Tekmar 3000) devices using FID-attached GC (HP 6890, Hewlett Packard). Result: THMs concentration detected at Gangneung-si was 0.0086mg/L, Goseong-gun 0.0019mg/L, Donghae-si 0.0099 mg/L, Samcheok-si 0.0016 mg/L, Sokcho-si 0.0057 mg/L, Yangyang-gun 0.0027 mg/L and Taebaek-si 0.0038 mg/L. As the THMs composition rate, chloroform constitutes 51.4% followed bybromodichloromethane 22.3%, bromoform 15.2% and dibromochloromethane 11.1% respectively. Conclusion: Throughout the entire THMs survey areas and period, the maximum concentration was 0.072mg/L, which did not exceed the water quality standards (0.1 mg/L), and the overall average concentration was very low at 0.0044 mg/L.

Many risk factors exist for chemotherapy-induced nausea and vomiting (CINV). This study utilized a multivariate projection technique to identify which risk factors were predictive of CINV in clinical practice. A single-centre, prospective, observational study was conducted from January 2007~July 2010 in Singapore. Patients were on highly (HECs) and moderately emetogenic chemotherapies with/without radiotherapy. Patient demographics and CINV risk factors were documented. Daily recording of CINV events was done using a standardized diary. Principal component (PC) analysis was performed to identify which risk factors could differentiate patients with and without CINV. A total of 710 patients were recruited. Majority were females (67%) and Chinese (84%). Five risk factors were potential CINV predictors: histories of alcohol drinking, chemotherapy-induced nausea, chemotherapy-induced vomiting, fatigue and gender. Period (ex-/current drinkers) and frequency of drinking (social/chronic drinkers) differentiated the CINV endpoints in patients on HECs and anthracycline-based, and XELOX regimens, respectively. Fatigue interference and severity were predictive of CINV in anthracycline-based populations, while the former was predictive in HEC and XELOX populations. PC analysis is a potential technique in analyzing clinical population data, and can provide clinicians with an insight as to what predictors to look out for in the clinical assessment of CINV. We hope that our results will increase the awareness among clinician-scientists regarding the usefulness of this technique in the analysis of clinical data, so that appropriate preventive measures can be taken to improve patients' quality of life.

The health-related habits, dietary behaviors and health status as well as the relationships between the health-related habits and dietary behaviors and the health status were investigated in the subjects of the middle aged(20 male and 50 female with the average age of 56.4$\pm$6.1) and the elderly(15 male and 15 female with the average of 68.4$\pm$3.6) living in Chonju. The survey included the personal interview using questionnaires, anthropometric measurement and biochemical tests in December, 1998. The breakfast irregularity was shown in 5.7% of male and 10.8% of female. The consumption of generally lightly salted foods was practiced in half of the subjects. The prevalence of smoking and alcohol drinking were shown in 20% and 31.4% of male group respectively. As judged by their body mass indices(BMI), none of the subjects was belong to the obesity group. However, the considerable degree of overweight was found in female subjects. The upper-body obesity was more prevalent in female compared to male group. The percentages of the anemic subjects as judged by WHO hemoglobin level were found to be relatively high specially for female(26.2%). The blood pressure, serum total cholesterol and LDL-cholesterol determination showed that the middle aged males and the elderly females tend to have higher levels compared to the different age bracket subjects from two-way ANOVA. Therefore, it can be assumed that the middle aged males and the elderly females are under the greater risk than the other groups. The analysis of the relationships between health-related habits and dietary behavior, and the health status showed that the regularity of breakfast, the consumption of lightly salted foods, the frequency of exercise and the alcohol drinking pattern influenced the city dwellers and the risk-related health habits as well as dietary behavior.

In this study, a normative script was designed for service design of coffee shop based on user's current and expected script. 1) Activities contained in current and expected script were identified. 2) High frequency activities were selected from current and expected script. Then they were combined and sorted by scene. 3) Importance of the integrated scenes and activities was assessed. 4) According to certain rules, unnecessary activities were deleted, or excluded as optional activities. Then, the remaining activities were classified by scene and listed in order to complete one normative script. Each activity belonging to each scene became a service encounter. Scenes consisted of 'Entering', 'Settling', 'Ordering', 'Waiting for drinks', 'Receiving drinks', 'Spending time drinking beverages', 'Go to the toilet', and 'Get out'. There were 2 activities in 'Entering', 6 activities in 'Settling', 11 activities in 'Ordering', 2 activities in 'Waiting for drinks', 4 activities in 'Receiving drinks', 6 activities in 'Spending time drinking beverages', 3 activities in 'Go to the toilet', and 4 activities in 'Get out'. Specific points were discussed along with these results, and the significance and limitations of the study were added at the end.

Milk contains a number of nutrients required for human growth and development, such as disaccharide lactose which is significantly contained in milk and dairy products. About two thirds of world populations are reportedly suffering from lactose intolerance after drinking milk. Lactose intolerance is defined as a maldigestion of lactose in the human intestine with typical symptoms of abdominal pains, bloating, and diarrhea. In this study, incidence of lactose intolerance has been investigated for the elementary school children for 1 year from July, 2010 to June, 2011. It is found that about 70% of the total elementary students have joined the school milk program. Out of 636 total students that participated in this study, 449 were from the metropolis, 85 from middle-sized city, and 102 from the small town including rural areas (small town/rural areas). For distributions of lactose intolerance, 154 students (24.2%) were found to be positive among the total 636 subjects. Based on the size of the city, the symptoms were the most prevalent for the students in the small town/rural areas at 31.4% (32/102), followed by 30.6% (26/85) in middle-sized city, and 21.4% (96/449) in the metropolis. On the other hand, gender had no significant effect on the incidence of lactose intolerance, shown those for boys and girls were 24.8% (77/310), 23.6% (77/326), respectively. Further research is needed to confirm the correct incidence of lactose intolerance symptoms as the frequency is significantly affected by subject's digestive functions including irritable bowel syndrome.

Aim: To determine whether induced abortion (IA) increases breast cancer (BC) risk. Materials and Methods: A population-based case-control study was performed from Dec, 2000 to November, 2004 in Shanghai, China, where IA could be verified through the family planning network and client medical records. Structured questionnaires were completed by 1,517 cases with primary invasive epithelial breast cancer and 1,573 controls frequency-matched to cases for age group. The information was supplemented and verified by the family planning records. Statistical analysis was conducted with SAS 9.0. Results: After adjusting for potential confounders, induced abortions were not found to be associated with breast cancer with OR=0.94 (95%CI= 0.79-1.11). Compared to parous women without induced abortion, parous women with 3 or more times induced abortion (OR=0.66, 95%CI=0.46 to 0.95) and women with 3 or more times induced abortion after the first live birth (OR=0.66, 95%CI =0.45 to 0.97) showed a lower risk of breast cancer, after adjustment for age, level of education, annual income per capita, age at menarche, menopause, parity times, spontaneous abortion, age at first live birth, breast-feeding, oral contraceptives, hormones drug, breast disease, BMI, drinking alcohol, drinking tea, taking vitamin/calcium tablet, physical activity, vocation, history of breast cancer, eating the bean. Conclusions: The results suggest that a history of induced abortions may not increase the risk of breast cancer.

Background and Purpose : The hemiplegic upper extremity is affected in many stroke patients, and recovery is often poor. The purpose of this study was to assess the efficacy of electroacupuncture (EA) in enhancing the upper extremity motor and functional recovery of ischemic stroke patients. Subjects and Methods : Forty ischemic stroke patients (the upper extremity Fugl-Meyer motor scale (FM) score lower than 46, lesion location within middle cerebral artery territory) within 2 weeks of stroke onset were randomly allocated to either an EA group that received EA treatment or a control group that received only routine ward care. The EA was applied at Quchi-Shousanli (LI11-LI10), Waiguan-Hegu (TE5-LI4) points on the hemiparetic side six times per week for 4 weeks. The frequency of stimulation was 25-50Hz and the intensity was set at a level sufficient to induce muscle contraction. EA treatment was given for 30 minutes and all patients of both groups received standard rehabilitation program. Outcomes were assessed, in a blind manner, before treatment began and at 4 weeks after treatment, with the FM, the Motor Power score (MP) for shoulder/elbow, and the subsection of the Modified Barthel Index (MBI) for drinking/feeding/dressing upper body/grooming. Results : These 2 groups had comparable clinical characteristics, lesion location, lesion size, and pretreatment impairment scores. By the end of treatment, the EA group showed significantly more improvement than the control group in the subsection of the FM for shoulder/elbow/coordination (6.4 vs. 3.7; P=0.047) and the MP for shoulder/elbow (5.3 vs. 3.3; P=0.008). The subsection scores of the MBI for drinking/feeding/dressing upper body/grooming were not significantly different between two groups. No adverse effects due to treatment were found Conclusion : These results suggest that EA enhances the upper extremity motor recovery of acute stroke patients. However, this study failed to demonstrate any significant functional benefit related with upper extremity. Future study should be carried out in a larger sample size and use the functional outcome measure that is more specific and sensitive to the upper extremity.

Objectives: The purpose of this study was to examine the association between depression and poor oral health in Korean elderly using Korean version of the Patient Health Questionnaire-9 (PHQ-9) for assessment of depressive symptoms. Methods: This study used the data from Korean National Health and Nutrition Examination Survey (KNHANES VI-2). The study included 1,454 elderly Korean aged over 65. Variables included demographic characteristics (gender, age), socioeconomic factor (income, education), systemic diseases, oral health related factor (tooth brush, dental products), health related factor (alcohol drinking, smoking), and depression. Logistic regression analysis was used as sequential models. Effects were quantified as odds ratios (OR) and 95% confidence intervals (CI). Results: From frequency analysis, being female, primary school or less, non-alcohol drinking, poor oral health were significantly related to depression. In the multiple logistic regression model, depression was significantly associated with poor oral health (OR=1.96, CI=1.15-3.53) after adjustment for other covariates including demographic characteristics, socioeconomic factor, systemic diseases, oral health related factor, and health related factor (OR=1.91, CI=1.13-3.27). Conclusions: Depression had an influence on the poor oral health after adjustment as confounding variable in the elderly. It should be focused on the health promotion for the elderly vulnerable to depression and poor oral health. The development of the mental health and oral health should be established.

Objectives : To prevent stroke, it is very important to reduce risk factors which might cause stroke. However, previous studies that having investigated coffee consumption associated with stroke reported various results. In addition, there were only a few studies based on the Korean population. Therefore, we studied the association of coffee consumption and the possibility of getting stroke among Koreans. Methods : A case-control study was carried out on 207 cases(stroke patients) and 207 controls(non-stroke patients) in a hospital. Information on characteristics, health habits, dietary habits and coffee consumption were obtained through direct interview by using an organized questionnaire; WHR(Waist-Hip Ratio) was determined through physical examination. The coffee consumption was classified by the average frequency of intake, such as less than 1 cup/day, 2-3 cups/day, more than 5 cups/day). Possible confounding effects of age, sex, smoking and alcohol drinking were controlled by multiple logistically regressive analysis. Results : After adjusting age and sex, coffee consumption significantly increased risk factors of stroke(${\leq}$1 cup/day OR=1.018, 95% CI=0.631-1.644; 2-3 cup/day OR=1.782, 95%CI=1.032-3.079;${\geq}$5 cup/day OR=1.210, 95% CI=0.588-2.490). When other factors were controlled, the risk factors of stroke were associated with alcohol drinking, whereas no significant association was observed with coffee consumption. Conclusion : Coffee consumption is not a major risk factor of causing stroke in this study. Prospective and cohort study on the association between coffee consumption and the possibility of getting strokes among the Korean population will be needed in the future.
