The purpose of this study was to analyze the internet usage patterns among adolescents and to provide basic data for the development of internet addiction prevention program. The subjects of this study were 1169 students in middle and high school students in Seoul, Korea. Self-administered questionnaires were employed and data were analysed by SPSS 12.0. Major conclusions were as follows: 1. Most of the students were found to be the normal internet users. On the other hand, potential risk group was 8.2% and high risk group was 4.7%. Every students have had an experience of inter use. The 90.6% of the students' households had internet links. The percentage of students who were using internet more than 3 hours a day was 25.7%, and The most popular type of website was entertainment. 2. Male students showed greater percentages of potential risk and high risk group than female students. The students having parents in divorce, remarriage and separation were more likely to be in potential risk group than those having normal parents. The staying alone in home after school and small sleeping time were positively related to high level of internet addiction. 3. The characteristics of the students in potential risk and high risk group were longer duration of the internet use, internet use through the whole week, frequent internet use late at night, frequent use of pornographic site, main purpose of internet use for entertainment and shortage of rest during internet use. This study results had an limitation of generalizing to entire Korean adolescents because the sample of this study was middle and high school students living in Seoul. Future study was needed for the analysis of internet use behavior of the entire Korean adolescents, and for the identification of the accurate predictors for adolescents' internet addiction.

The purpose of this study was to investigate the relationship between perceived risk and purchasing behavior of clothing gift among adult women. Data were collected from 258 adult women reside in Kwangiu who have ever been to purchase clothing gift during recent six months using a qusetionaire. Frequency Analysis, Factor Analysis, Correlation Analysis, T-test were carried out in the collected data. The findings were as follows; 1. The types of risks that respondents perceived when they purchased clothing gift were identified as practical-economic risk, the social-psychological risk, the fashionable risk and the time-refunding risk. 2. The higher the self-satisfaction motivation was, the higher the social-psychological risk and the higher the practical motivation was, the higher the practical-economic risk (P<.001). 3. The degree of the perceived risks of the Low Planning Group was higher than that of the High Planning Group (P＜.001). 4. When the respondents perceived social-psychological risk high, they considered brand, fashionability, and store type as more important selective criteria and when the practical-economic risk perceived high, practicality, store service were conidered more important (P＜.05). 5. When respondents perceived social-psychological and fashionable risk high, they used both personal information and non-personal information high (P<.01).

Objectives: The aim of this study was to observe the changes of women's postpartum symptoms, the quality of life and depression scale over the first six weeks after childbirth. Methods: Twenty seven mothers who received Korean medical treatment in the outpatient department treatment (from September 27th, 2017 to January 5th, 2018) were evaluated for Verbal numerical rating scale (VNRS), edema index, EuroQol Visual Analogue Scale (EQ-VAS), and Edinburgh Postnatal Depression Scale (EPDS). Results: There were 17 high risk participants (63.0%) and 10 normal participants (37.0%). The VNRS of edema is the highest in the first week, and the VNRS of joint pain is the highest from the second week to the sixth week in all patients. The Extra Cellular Water/Total Body Water (ECW/TBW) of high risk group significantly decreased from $0.403{\pm}0.011$ to $0.387{\pm}0.006$(p<0.05) in the first 2 weeks. The ECW/TBW of normal group significantly decreased from $0.393{\pm}0.070$ to $0.383{\pm}0.011$ (p<0.05) in the first 2 weeks. The EQ-VAS of high risk group increased from $64.12{\pm}13.941$ to $69.35{\pm}18.155$ (p<0.05) in the first 2 weeks. But this difference was not significant statistically (p=0.234). The EQ-VAS of normal group significantly increased from $62.50{\pm}21.763$ to $74.00{\pm}9.661$ (p<0.05) in the first 2 weeks. The difference of EPDS was not statistically significant between the first week and the sixth week in every participants. Conclusions: VNRS was the highest in edema in the first week, joint pain was the highest from the second week to six week. The edema index of high risk groups was higher than that of the normal group in the first week (p<0.05). The EQ-VAS of normal group significantly increased (p<0.05) in the first 2 weeks but high risk group didn't. In the EPDS, the ratio of nine or more points of high risk group was more than twice than normal group in the first 2 weeks.

Purpose : This study is a descriptive research to provide basic factors of posttraumatic stress in Firefighters. This study was carried out to develop the effective program for the fire fighters to cope with the posttraumatic stress following the disasters. Methods : The questionnaires were collected among fire fighters who serviced in K and I community from April 1 to June 30 in 2008. Total 304 questionnaires were analyzed by SPSS WIN program for descriptive statistics, Pearson's correlation coefficient and t-test. Results : 1. 48.0% of 300 fire fighters were at the age of 31-40, and 42.3% were under 30. 2. Work burden had a significant difference of 2.30 in low-risk group, 2.60 in high-risk group(t-value=-3.85, p=0.00). However, life event had no significant difference 0.79 event in low-risk group, 1.41 event in high-risk group(t-value=-2.27, p=0.24). 3. Concerning posttraumatic stress factors, there was positive correlation between mobilization impact level r=0.38(P<0.01), work burden r=0.38(p<0.01), and life event r=0.27(p<0.01). 4. According to the Symptom Check List-Revised(SCL-90-R), somatization had a significant differences(t-value=5.46, p=0.00), obsessive-compulsive(t-value=7.16, p=0.00), interpersonal sensitivity(t-value=6.15, p=0.00), depression(t-value=6.62, p=0.00), anxiety (t-value=7.33, p=0.00), hostility(t-value=5.94, p=0.00), phobia anxiety(t-value=6.85, p=0.00), paranoid ideation(t-value=5.55, p=0.00), psychotism(t-value=6.52, p=0.00) in low-risk and high-risk group. Conclusion : As a consequence, mobilization impact, work burden, and life event were the influential factors on posttraumatic stress. Also, high-risk group revealed significantly higher score on all 9 scales. The information obtained from surveys made recommendation to develop the intervention of stress management to control mobilization impact and posttraumatic stress.

Objective: The clinical significance of mass screening for thyroid carcinoma remains unclear. This study was carried out to clarify the value of mass screening for thyroid carcinoma. Materials and Methods: From December 1997 through July 1998, a total of 1,401 subjects who were enrolled to receive breast screening or follow-up examination for breast cancer were included in this study. Thyroid glands were examined by 10 MHz ultrasonography by one experienced radiologist. The patients with thyroid nodules were classified into 2 groups according to their potential risk of malignancy by ultrasonographic findings(high-risk : hypoechogenicity, microcalcification, irregular margin, taller than wider shape). High-risk patients were advised to undergo fine-needle aspiration biopsy and thyroidectomy. The characteristics of the thyroid cancers detected by ultrasonographic mass screening were compared by those of clinical thyroid cancer excluding male patients during the same period. Results: Thyroid nodules were detected in 353(25.2%) of the subjects and 259(73.4%) were listed in the low-risk group and 94(26.6%) in high-risk group. Among 94 patients in the high-risk group, 43 underwent thyroidectomy and 37 turned out to have thyroid carcinomas. Thus, the detection rates for carcinoma were 2.6% of all subject, 10.5% of the detected nodules, 36.4% of the high risk women and 86.0% of the operated cases. The tumor size was significantly smaller in the mass-screening group than in the clinical cancer group(p<0.05). However, there was no statistical differences between two groups in the prevalences of neck node involvement and extracapsular invasion and the patients distributions by AMES score, MACIS score and TNM stage. Conclusion: Ultrasonogrpahic mass screening may be useful for the early detection of thyroid carcinoma in women who are scheduled to have breast examination.

Purpose: This study examine the effects of music therapy and phone counseling on postpartum depression and maternal identity in high risk women. Methods: A nonequivalent control group time series research design was employed. Eighteen women comprised the experimental group and seventeen women, the control group. Experimental group received 4 weeks of music therapy and phone counseling. Postpartum depression and maternal identity were measured prior to intervention and on the 1st, 2nd, and 4th weeks after its introduction. Results: The first hypothesis (i.e., "the degree of postpartum depression would be lower in the experimental group than in the control group in a month's time") was not supported (z=-0.47, p=.641). The second hypothesis (i.e., "the degree of maternal identity would be lower in the experimental group than in the control group in a month") was not supported as well (z=1.08, p=.285). Conclusion: There is the need to monitor long-term effects of music therapy and phone counseling on high risk postpartum women, beyond 4 weeks observed in this study. Additionally, the development of music therapy tailored to high risk individuals and systematic phone counseling protocols for postpartum depression is required.

Purpose: Percutaneous endoscopic gastrostomy (PEG) is a safe method to feed patients with feeding difficulty. This study aimed to compare the outcomes of conventional PEG and laparoscopic-assisted PEG (L-PEG) placement in high-risk pediatric patients. Methods: In our tertiary pediatric department, 90 PEG insertions were performed between 2014 and 2019. Children with severe thoracoabdominal deformity (TAD), previous abdominal surgery, ventriculoperitoneal (VP) shunt, and abdominal tumors were considered as high-risk patients. Age, sex, diagnosis, operative time, complications, and mortality were compared among patients who underwent conventional PEG placement (first group) and those who underwent L-PEG placement (second group). Results: We analyzed the outcomes of conventional PEG placement (first group, n=15; patients with severe TAD [n=7], abdominal tumor [n=6], and VP shunts [n=2]) and L-PEG placement (second group, n=10; patients with VP shunts [n=5], previous abdominal surgery [n=4], and severe TAD [n=1]). Regarding minor complications, 1 (6.6%) patient in the first group underwent unplanned PEG removal and 1 (10%) patient in the second group had peristomal granuloma. We observed three major complications: colon perforation (6.6%) in a patient with VP shunt, gastrocolic fistula (6.6%) in a patient with Fallot-tetralogy and severe TAD, and pneumoperitoneum (6.6%) caused by early tube dislodgement in an autistic patient with severe TAD. All the three complications occurred in the first group (20%). No major complications occurred in the second group. Conclusion: In high-risk patients, L-PEG may be safer than conventional PEG. Thus, L-PEG is recommended for high-risk patients.

Purpose: The purpose of this study was to examine the effects of team-based learning (TBL) on nursing students' communication ability, problem-solving ability, self-directed learning, and nursing knowledge related to high-risk pregnancy nursing. Methods: This quasi-experimental study used a nonequivalent control group pretest-posttest design. The participants were 91 nursing students allocated to an experimental group (n=45) and a control group (n=46). The experimental group received TBL lectures three times over the course of 3 weeks (100 minutes weekly) and the control group received instructor-centered lectures three times over the course of 3 weeks (100 minutes weekly). Data were collected by questionnaires from September to November, 2019. Data were analyzed using the chi-square test, paired t-test, and independent t-test. Results: After the intervention, the mean scores of problem-solving ability (t=-2.59, p=.011), self-directed learning (t=4.30, p<.001), and nursing knowledge (t=3.18, p=.002) were significantly higher in the experimental group than in the control group. No significant difference in communication ability was found between the experimental and control group (t=1.38, p=.171) Conclusion: The TBL program was effective for improving nursing students' problem-solving ability, self-directed learning, and nursing knowledge. Thus, TBL can be considered an effective teaching and learning method that can improve the learning outcomes of high-risk pregnancy nursing in women's health nursing classes. The findings suggest that TBL will be helpful for future nursing students to develop the nursing expertise necessary for providing nursing care to high-risk pregnant women.
