The aim of this study is having the status, knowledge and attitude of the high school attendees toward smoking be analyzed, helping to make effective health education methods to diminish adolescent smoking habits. The field self-questionnaire investigation has been performed from Oct 10th through 23rd in 1999. The whole 427 cases were distributed to 1st and 2nd grade students of randomly selected men's high school in Seoul. And 414 cases (97%) were finally selected for analysis after exclusion of cases with insufficient information. The main contents of questionnaire are composed of several sectors; the general characteristics of the interviewees, the relationship with parents, the life style and the peer relationship in school. And smoking-related characteristics are taken into consideration, too. The major findings of the study are as follows: The smoking/non-smoking related factors are, in socio-demographical terms, the grade, average spending per month of the interviewees. And the degree of satisfactory relationship with parents is significant on smoking behavior. The higher, the degree of satisfaction on school life and relationship with designated teacher, the more chances of non-smoking habit. Poor academic grades and peer group dependability of interviewees cause higher smoking habit rate in other way. The self-interviewees grade and cohabitation with parents are also significant on both the attitude toward smoking habit and the knowledge on smoking statistically. The academic history and vocations of the parents and the academic grades of interviewees are also effective variables, but don't make any gap between groups knowledge on smoking. Smoking groups used to have positive attitude toward smoking habit. Both the attitude and knowledge on smoking by the consideration of Quit-smoking have statistically significance. The groups which have negative attitude and high knowledge on smoking quit-smoking into consideration. And the primary cause of quit-smoking is on health by smoking. Depression, stress, adult smoking in the house, peer group pressure, cigarettes advertisements on papers and magazines and smoking scenes on TV have positive correlation on forming smoking habit (p〈0.001) But the knowledge on diseases triggered by smoking has negative correlation on forming smoking habit. (p〈0.05, p〈0.001). Social factors as monthly spending, relationship and communication with parents, the degree of satisfaction in school life, academic grades and student-teacher relationship have crucial negative correlation on smoking habit. That is to say, the higher, the monthly spending is, the worse, the relationship with parents and teachers is, the lower, the academic grades of the student is, the percentage of the interviewees who have smoking habit seems to get higher.

The purpose of this research is to be grasp the relation between lumbago incidence rate and research hypothesis in the effects of sex life of the middle-aged couples in Taejon area upon lumbago. This writer had questionaired the 400 middle-aged couples in Taejon city - Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from June 1, to June 30, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows; 1. 145(69.37%) subjects of total 209 had low back pain experience after their sexual lives. 2. In the number of sexual times a week, low back pain incidence were the most rate in 1-2 times as 41.55%, each other had a statistically significant relation (P<0.01). 3. In age and lumbago incidence rate, the 30s was 37.75% and each other had a significant relation (P<0.05). 4. In weight and lumbago incidence rate, the level of 50kg~60kg was highest and each other didn't have a significant relation (P>0.05). 5. In the mean sexual time, the period of 11~20 minutes was 29.47% and each other had a significant relation (P>0.01). 6. In a day time of sexual life and lumbago incidence rate, midnight was the highest rate(36.23%) and each other didn't have a significant relation (P>0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P>0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate(46.12%) and each other didn't have a significant relation (P>0.05). According to the results of our research, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. So it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an prevention education for low back pain the key points.

The purpose of this study is to compare by learner groups(K-12, geology-related majoring students, science teachers) how geologic fieldwork education cases in domestic and foreign papers for recent 20 years reflect the elements of inquiry in field geology. The total number of analyzed cases is 53(58 for double counting), and the analysis was conducted on the elements of inquiry in field geology and their sub-element. As a result, there was a clear difference between the cases of geologic fieldwork education for K-12 and college students majoring in geology-related disciplines, in the way of reflecting elements of inquiry in field geology. Because most of K-12 target fieldworks were designed based on the curriculum, it mainly included 2-3 elements of observations, representations, and/or abductive reasoning. On the other hand, because fieldworks for geology-related major students aim to train geologic experts, it diversely contained four or five of the elements of inquiry in field geology, including spatial thinking and diachronic thinking in a high proportion, and also frequently used activities that require specialized skills such as geological mapping. Fieldworks for science teachers were found to have mixed features of K-12 and geology-related major students. Considering the diversity of included inquiry elements, similarities with the activities performed by geologists, and the autonomy of learners, it was analyzed that geologic fieldwork for geology-related major students was more close to authentic geologic inquiry than fieldwork for others. Based on the results of this study, we suggested implications for improving geological fieldwork as authentic science inquiry.

This study aims to review the standard operation status on wood, pulp and paper industry in Korea according to the industry standardization law which has been revised for strengthening expertise of relevant department and to propose a management strategy of Korean Standards (KS) in figure. Korea Forest Service (KFS) is the responsible department of managing KS on the wood, pulp and paper industry from 2015, and currently opertates three expert committees (wood and wooden construction, wood-based materials, pulp and paper) and wood and paper industry council to review 426 standards. To support an improvement of technical competency and securement of marketability of Korean wood industry, it is about time to review the standards and to develop practical standards since it is managed by specialized department. For this purpose, it is necessary to establish a systematic approach on the management of KS, based on thorough analysis of current KS. To remove possible technical barrier on trade due to the differences of standards between countries, the conformity with international standards is necessary. Also, for sustainability of standard management system, training specialists and building their capability is essential.

Objective: The purpose of this study was to systematically review the articles using accelerometer to measure activity of daily living of patients with stroke. Methods: Depending on selection criteria, 13 studies were searched for PubMed, EMBASE, and Cochrane library database from February 2014 to March 2014. A total of 331 papers were searched, and 13 of these were selected. Results: In studies of 13 selected, acute, subacute, and chronic patients with stroke were enrolled. The kind of accelerometer was uniaxial, biaxial, and triaxial, activity monitor. Measurement activities were mainly arm activity, walking activity, and attachment sites were also various depending on the measurement activities. A measured variable was the total number of activities, the movement speed of the patients, ratio between affected and non-affected, and motion analysis. The result indicated that significant correlation with the other assessment tools in all studies. Conclusions: Accelerometer will be applied with a tool for measuring activity of daily living of patients with stroke, depending on activities characteristics. Further, we need accelerometer studies to apply with a variety of assessment in clinical practice or community settings.

This study investigated the types, forms, and origination of litter found along one hiking course in Moaksan Provincial Park, 'Jungin-ri Course'(entrance-ridge-valley-peak). In addition, a survey was conducted to understand hikers' litter control awareness in order to determine possible backcountry litter control measures. The following are the results of this study: 1. For the litter Sequency investigation, 199 recyclable pieces of litter were found on the mid-slope(61.6%), 89 by the entrance(27.6%), 19 in the valley(5.9%) and 16 on the peak(4.9%). A total of 323 pieces of litter were found. Paper materials were the most common, followed by plastic containers such as PET bottles and yogurt containers. Of particular interest, 288 papers and cans were found on the mid-slope(46.9%). By the entrance, more plastics and bottles were found. 2. There were 614 pieces of flammable litter collected and only 19 pieces of non-flammable. Most of the flammable litter, including snack pacts, plastic bags, processed lumber, cigarette butts, tissues, cigarette boxes, and fabric was found on the mid-slope. 3. Very little food waste was found throughout the whole site proving that the policy prohibiting hikers from cooking and eating at the designated sites has been effective. However, food waste is difficult to find because it naturally decays with time. 4. $X^2$-test was used to find different types of litter and their verified origination frequency. It was found that recyclable litter, and food waste took about 1%. In addition, recyclable litter, especially bottles, was found relatively frequently by the entrance. Flammable litter was found most often at the peak. 5. The questionnaire results showed that 48.2% of the respondents "shorten their hiking journey and purchase food outside the entrance" and 29.6% said that they "bring a packed meal from home". Only 8.2% said that they "cook something when an appropriate location is found". At the Jungin-ri course, a few hikers brought their own food to eat or cook, but most hikers purchased something to eat onsite. 6. The results of the question about having experience littering while hiking showed that 19.3% litter and 79.2% do not. Those that responded "yes" gave various reasons for littering. 63.6% claimed, "there are no designated trash containers". 15.9% said they litter subconsciously. Finally, 3.2% insist that they litter "because food naturally decomposes". 7. As a result of the overall satisfaction according to the Likert scale and the analysis with an average of 14 variables, it was found that the average "toxic litter control convenience" was 2.41 with very low satisfaction. Thus, the results indicate the importance of providing appropriate back country litter control facilities.

Objectives: This study was performed to review studies on Essential Tremor (ET) in Traditional Chinese medicine (TCM). Methods: We reviewed papers in the China National Knowledge Infrastructure (CNKI) from 2007~2016. Search keywords were 原发性震颤, 特发性震颤, essential tremor and idiopathic tremor, and excluded non-clinical studies, non-related to ET or TCM studies, theses for degrees and non-Randomized Controlled Trial (RCT). The quality of the articles was assessed by Jadad scale and the Risk of Bias (RoB). Results: Thirteen studies were selected. 'Criteria for the diagnosis of ET' was most frequently used as diagnostic criteria. 'Tremor rating scale' was primarily used for outcome measurement. Meta-analysis of nine trials revealed the effective rate of acupuncture and Western medicine (WM+Acu) groups was significantly higher compared to the WM group (RR: 1.48, 95 percent CI: 1.20 to 1.82, p=0.0002, $I^2=0$ percent) and tremor rating scale was also significantly decreased in the treatment group (MD: -1.35, 95 percent CI: -2.17 to -0.54, p=0.001, $I^2=0$ percent). Also, effective rates of Electro-acupuncture (EA) and Chinese herbal medicine (CHM) groups were significantly higher than that of the WM group {(RR: 1.53, 95 percent CI: 1.22 to 1.92, p=0.0003, $I^2=0$ percent) in EA vs. WM and (RR: 1.35, 95 percent CI: 1.16 to 1.57, p<0.0001, $I^2=0$ percent) in CHM vs. WM}. However, the quality of selected clinical studies was poor. Conclusions: Treatment of ET in TCM may be more effective and safe than in Western medicine. Therefore, we hope this study will lead to further clinical research on treatment of ET in Korean medicine.

Objective: The purpose of this study was to perform a systematic literature review focusing on international studies to identify various factors affecting the quality of life(QOL) of dementia patients admitted to long-term care facilities. Methods: From January 2000 to July 2018, the articles published in foreign journals were searched through CINAHL and MEDLINE databases. The main search terms were'dementia or Alzheimer's'. 'quality of life', 'long-term care', 'care home', 'nursing home', 'care institution', 'residential care', 'small- scale setting'. The first 1706 articles were searched, but 10 studies were selected using the selection and exclusion criteria. Results: Analysis of ten cross-sectional studies showed that factors such as physical functioning status, ability to perform activities of daily living, and cognition showed a positive correlation with QOL. Depression and anxiety, severity of dementia, and neuropsychiatric symptoms were found to be negatively correlated with QOL. In addition, two longitudinal studies have confirmed that factors affecting QOL are affected by individual functional status and social environmental factors rather than the size and form of care facilities. Conclusion: This study summarized 10 papers and analyzed them through a systematic review of literature. We found that factors such as individual characteristics and social environment determine QOL of patients with dementia. In this study, various intervention methods to improve QOL of patients with dementia should be developed and used in long-term care facilities by identifying the factors affecting QOL of dementia patients and using them.

Purpose - Before the economic reforms, the Chinese communication industry was poorly developed. After China's entering to WTO, the Chinese market were gradually opened, domestic companies will be faced with more and more pressures of competition from the world rival countries. As time goes on, the overseas telecommunications companies will occupy the Chinese market with the opening of China Telecommunications market to outside. So this paper focuses on problems and development methods based on the research about the present situation and development methods of communication industry(communication manufacturing industry and communication manufacturing industry) in China. Research design, data, and methodology - This study analyzed the policies of China's entering to WTO. This paper observed previous researches and made an empirical research on Chinese communication industry based on the governmental policies, strategies, books and previous papers with several kinds of clear data announced formally by China authorities. Results - Most recently, reorganization of the communication industry has brought good opportunities for the development of the communication manufacturing enterprises. This paper analyze policy changes of Chinese communication industry, the status of communication manufacturing industry and communication service industry. Finally, this study for further research analyzes the existing problems and puts forward some practicable measures to solve them. Conclusions - Looking ahead, with China's rapid economic development and steady deepening of reform and opening-up, the Chinese communication industry is faced with an even broader prospect of development. Chinese communication industry will be become the pillar one in national economy after 10 years development. Foreign communication companies accelerated investment and progresses to Chinese information and communication markets. Positive ones are more foreign investment, export increase, domestic innovation, communication industry made steep growth. But negative ones are obstacles of domestic companies' development and jobless rate increase etc. Second communication manufacturing industry made good development, but computer and TV related industry made decline in growth. Third, market sizes of internet and mobile services are growing but the size of wired communication services is downsizing gradually. To overcome them, the studies of components or parts of communication manufacturing industry are needed individually. Second China Unicom, China Telecom, China Mobile etc. are Chinese representatives. The sales volumes are very similar at the beginning, but now they are different and make big differences. So the analysis about, their differences and its impact, are needed.

The collection of the National Museum of Modern and Contemporary Art, Korea, features a sansu folding screen that was created in 1940 to commemorate the sixtieth birthday of Soseok Kang Jin-Koo. It was created by six oriental painters, who were among the ten best painters in that era. The folding screen has been previously repaired and restored; however, owing to damage such as twisting of its wooden frame, abrasion, and moisture stains, rigorous conservation treatment is required. Hence, scientific research was conducted to analyze the textile, paper and pigments employed while creating the folding screen, to identify the associated material properties. Results showed that the textile used in the screen's picture and janghwang comprise synthetic fibers and natural fibers such as cotton and silk. Various types of papers were used in the folding screen, such as those from mulberry, herbaceous, and coniferous fibers. Furthermore, calcite deposits were found on the base of every picture, and certain colors employed by the artists appear to be produced from different pigments.
