The study is designed to compare differences between male and female Internet users in present Internet use conditions, Internet addition, self-respect, and deviation from a health life and analyze and understand factors causing compulsive Internet use. The research is aimed at suggesting basic information to guide a desirable direction for healthy and effective Internet use. The survey of 456 students majoring in public health at some universities in the Pusan-Kyungnam areas was made in November, 2006. The results are as follows: As for general information on those surveyed the number of the males was 50(11.0%) and that of the females was 406(89.0%), which shows an absolute higher ratio of the female respondents. On a question of Internet use frequency 62% of the male students and 44.6% of the female students answered they use the Internet everyday. Also the male respondents' Internet use time was longer. 64.0% of the male students use the Internet for games and entertainment, which were the highest ranked reason. 64.4% of the female students said they use the Internet to check e-mails. To all the questions assessing Internet addiction, the male users' answers implied higher addiction levels, but there wasn't statistically significant difference. However, the statistically outstanding distinction between the two sexes on deviation from a health life is shown in smoking, cheating in a test, obscene video/books, and conflicts with parents. The most answered deviations among the male respondents are smoking, cheating in a test, and obscene video/books, while conflicting with parents is for the female students. On self-respect the survey has found statistical differences in five questionnaire items and the female showed higher levels in all those questions. The male students answered cheating in a test(0.399), conflicts with parents(0.391), and Internet use time(0.242) have significant plus(+) influences on their compulsive internet use, while alcohol(-0.308) has a minus(-) influence. The female students answered self-respect(0.114), alcohol(0.097), obscene video/book (0.218), conflicts with parents (0.243), and Internet use time (0.284) factors have plus(+) effects.
서울 상공(615 m)에서의 PM<SUB>2.5</SUB> 특성연구: 지표 입자 특성과의 비교 및 혼합고 영향 중심으로

대기 중 입자 농도 및 특성의 일변화에 있어서 기상요소가 중요하며, 특히 혼합고(planetary boundary layer, PBL)의 영향은 크게 영향을 미친다. 대기 혼합고는 일반적으로 온도가 비교적 낮은 밤에는 얕으며, 온도가 높은 낮 시간에는 대기 혼합고가 상승하여 혼합층 내부의 활발한 대류가 일어난다. 이러한 대기 혼합고의 변동에 따라 PM 농도 및 화학조성은 영향을 받으며, 이를 분석함으로써, 에어로졸 확산과 외부로부터의 유입에 대해 파악할 수 있다. 본 연구에서는 혼합고의 변화가 미세먼지 농도 및 특성변화에 미치는 특성을 파악하기 위하여 지표 측정 지점인 KIST에서 Aerodyne Aerosol Mass Spectrometer (AMS)를, 상공 측정 지점(>600 m)으로는 관악산을 선정하여 Aerosol Chemical Speciation Monitor (ACSM)를 각각 설치, 이용하여 실시간 측정 및 분석을 진행하였다. 고도에 따른 대기 관측에 앞서 두 기기 간의 aerodynamic lens와 vaporizer 등에서 오는 관측오차를 확인하기 위하여 validation을 진행하였다. Capture vaporizer가 적용된 ACSM의 cyclone inlet 조건만 변경하여 AMS와 동시에 가동하여 비교분석을 진행하였다. 이후 ACSM를 이용하여 상공(관악산)에서의 미세먼지 농도, 일변화, 화학적 특성을 실시간으로 측정하여 지표(KIST)의 AMS와 비교하였다. 이를 통하여 본 연구에서는 대기관측을 진행한 겨울 기간 동안 관악산의 해발고도를 기준으로 대기 혼합고의 변동에 따라 지상 데이터와 비교하여, 1) 상공 미세먼지의 특성 2) 고농도 발생 시 장거리 이동 영향 3) 혼합고가 도심 미세먼지 특성에 미치는 영향 등에 대하여 논하고자 한다.

Purpose The optimal number of lesions to measure for response assessment from fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) is not validated for lung cancer. We compared 1 lesion and up-to-5 lesion measurements for response assessment in lung cancer per PET Response Criteria in Solid Tumors (PERCIST). Methods Patients with lung cancer with pre- and post-treatment PET/CT images were included. The standard uptake value corrected for lean body mass ( SULpeak) of up-to-5 hottest target lesions was measured at each time point. The percent changes of SULpeak of the single hottest lesion and the sum of up-to-5 hottest lesions were computed. Pearson correlation coefficient evaluated the strength of association between the percent changes of SULpeak values from the 1 lesion and up-to-5 lesion analyses. Response categories were complete metabolic response (CMR) with no perceptible lesion; partial metabolic response (PMR), stable metabolic disease (SMD), or progressive metabolic disease (PMD) using the threshold of 30% and 0.8 unit change in SULpeak; and unequivocal new lesion meant PMD. The concordance for response categorization was assessed by kappa statistics. Results A total of 40 patients (25 non-small cell lung cancer; 15 small cell lung cancer) were analyzed, all with 18F-FDGavid lung cancer. Average of 3 target lesions were measured for up-to-5 lesion analysis. Pearson’s r was 0.74 (P < 0.001) and increased to 0.96 (P < 0.001) when two outliers were excluded. Response categorization with 1 lesion and up-to-5 lesion analyses was concordant in 37 patients (92.5%, weighted kappa = 0.89). Conclusion Analyzing 1 lesion and up-to-5 lesions for response assessment by PERCIST showed high concordance in patients with lung cancer.

The aim of this study is to find out the correlations between health behaviours of young people and the relationships with social factors, which can be helpful for the development of health promotion programmes for youths. The main socializing arenas influencing children's development of health and health behaviour are school, peers and parents. In this study, the selected social factors are based on these arenas. And the following seven health-related behaviors were selected:smoking, drinking alcohol, drinking coffee, irregularity of taking main meals, regular exercise, brushing teeth, and use of medicine for nourishment or restoratives. These health behaviours categorized into two groups; health-promotioning and health-damaging behaviours. The results were summarized as follows; Significant positive correlations were found between health damaging behaviours-drinking alcohol, coffee, smoking, irregularity of main meals, drinking alcohol. But, No consistently significant correlations were revealed among health promoting behaviours and between health pormoting and health damaging behaviours. If total group were devided into four groups by gender and grade, these correlations were a little weak. Although such division, the correlations among health damaging behaviours were still significant. The result is also found that health behavious and various social factors were strongly correlated. Particularly, health damaging behaviours showed a consistent correlation with social factors. This consistensy was simillar to the figure of other contries in Europe. In conclusion,, a more comprehensive explanation on health behaviour became possible if the analysis on the correlations were made by dividing health into "health-promotion" and "health-damaging". And the health promotion programmes can be more effective when they focus on the correlation of health behavious and inter-relationships between health behavious and various social factors, rather than focus on individual behavious.
