The purpose of this study was to examine the symptom of dry mouth of workers, their subjective oral symptoms and factors affecting their oral health-related quality of life (Oral Health Impact Profile, OHIP-14) in an effort to provide information on the development of oral health promotion programs geared toward workers. The subjects in this study were the workers in five different companies in North Jeolla Province. After a survey was conducted from August 1 to September 20, 2012, the collected data were analyzed. The findings of the study were as follows: The office workers got 2.59 in oral dryness, and the sales associates got 1.82. The oral dryness of the former was severer than that of the latter (p<0.001). The irregular workers got 2.05 in OHIP-14, and the regular workers got 1.82 (p<0.001). Symptom of dry mouth had a positive correlation to OHIP-14 (r=0.456). OHIP-14 was positively correlated with age (r=0.209) and negatively with academic credential (r=-0.136). OHIP-14 was more significantly affected when their symptom of dry mouth was severer (${\beta}=0.383$, p<0.001), when they were older (${\beta}=0.221$, p<0.001) and when they felt they had oral diseases (${\beta}=0.146$, p<0.01). In conclusion, quality programs should be developed to promote the oral health of industrial workers in consideration of the influential factors for the oral health-related quality of life of the workers, and the government should pay more attention to related policy setting to improve the oral health of industrial workers.

This research aims to investigate into company workers' general characteristics and their awareness of the hygiene of the mouth and practice of it, in order to prepare schemes to improve the hygiene of their mouth. The findings of the research are listed in the following: First, the workers have a high level of awareness of the effect of tooth-brushing to prevent periodontal diseases but a low degree of awareness of its effect to prevent decayed teeth and of the necessity of mouth hygienic supplies. Second, they have a high level of awareness of the necessity and importance of scaling, but most of them do not have their teeth scaled periodically. To repeat, they have a high level of awareness of the necessity of dental examination, but not many of them put such awareness of theirs into practice. Third, married workers have a higher level of awareness of the hygiene of their mouth than unmarried ones do. The higher concern they have about the hygiene of their mouth, the more awareness they have of the hygiene of their mouth. Fourth, the higher monthly average income they have, the more frequently they put into practice their awareness of the hygiene of their mouth. And the poorer hygiene of their mouth they have, the more strongly they put into practice their awareness of the hygiene of their mouth.

This study intended to provide basic data required in establishing policies for improving the forestry management and the compensation standard for the loss from non-timber forest products by examining the cost of cultivating key medicinal herbs and the earnings from them to analyze the income. According to the income analysis on the cultivation of medicinal herbs, the average annual income per unit area of Adenophora triphylla var. japonica Hara was the highest as it recorded 14,233,000 won/10a and was followed by Pleuropterus multiflorus TURCZ. which recorded 4,121,000 won/10a, Gastrodia elata Blume 3,766,000 won/10a, Epimedium koreanum Nakai 3,537,000 won/10a, Atractylodes ovata (Thunb.) DC. 2,655,000 won/10a, Aralia continentalis Kitagawat 1,048,000 won/10a, Paeonia lactiflora Pallas 1,025,000 won/10a, and Bupleurum falcatum L. 919,000 won/10a. Compared with the income from major nuts and fruits analyzed in 2014, the average annual income per unit area for medicinal herbs was relatively higher. For Adenophora triphylla var. japonica Hara and Aralia continentalis Kitagawat, soots are used for food and the roots for medicine, it appears that it can become a new income source for the farming and mountain villages. Meanwhile, the price for Paeonia lactiflora Pallas is dropping due to Chinese imports, and also damage to the income from other medicinal herbs due to Chinese imports is expected with the implementation of Korea-China FTA in the future.

Quarrying industry is typical industry that troubled between the market and government regulations in the forestry. Especially, it is difficult to consider aspects of economics and environment, landscape, disaster at the same time. Therefore, Quarrying industry need revised statutes according to regulatory reform and mitigation. This study conducted to provide basic data for regulatory reform and mitigation in quarrying industry. We surveyed 22 article of mountainous districts management act and lower statutes to employers and business interests on quarry 55 places in the Republic of Korea. As a result, fulfillment status of environmental damage reduction and disaster prevention were satisfactory. But fulfillment status of landscape damage reduction were not applicable. This result is due to the social mood that emphasizes the forest landscape. But there is need to improve the efficiency of grit chamber through present standard on effluent(water pollution prevention). In conclusion, policies should be established for realistic regulation and developed industry to quarrying industry.

This study aims to suggest the necessary political implications for the introduction of green tourism in "Mountain Village Project" through the survey of local residents on the recognition of rural and mountain villages about the Village Development Projects. Direct survey using a structured questionnaire was executed to each local resident in different types of rural tourism villages such as the Mountain development village, the Green agricultural village, the Rural theme village, and mixed type of village between them. It was revealed that local residents in the Mountain development village had a positive reaction to the Project, whereas those in mixed type of village did not notice highly the change by the Project. Residents in the Mountain development village highly satisfied with the Project as improved income sources. In addition, it was shown that local residents recognised the necessity of social education and they highly wanted to participate in it. Residents in the Green agricultural village also wanted to put an effort to introduce an activity-based program for village development.

Wastepaper recycling has significant implications not only in providing scarce raw material input for the paper industry but in environmental concerns such as reducing solid waste disposal, energy conservation and preservation of forest resources. The objectives of this study was (1) to develop an econometric model of demand for and supply of wastepaper, (2) to forecast wastepaper consumption and price to the year 2000 applying the econometric models estimated and (3) to estimate the elasticity of variables which are included in the wastepaper supply and demand equations. In this study wastepaper was classified into three groups, old newsprint, old corrugated and mixed For each group such as demand and supply equation were estimated. The demand equations were estimated as a function of paper and paper product consumption and wholesale price index and supply equations as a function of wastepaper price, one year lagged paper and paperproduct consumption and transportation price. Applying the econometric models to forcasting results in the future consumption and supply of wastepaper projected as 11.645 million MT and 7.396 million MT in 2000, respectively. The rate of wastepaper self-supply is forcasted about 63.5% in 2000. Especially, the rate of old neswprint self-supply is predicted about 16% which means about 2.2 million MT of old newsprint should be imported from foreign countries. Lastly, some policy measures to promote wastepaper recycling rate based upon economic and physical characteristics of wastepaper and market structure are suggested.

Addicts pay more attention to addiction-related cues, such as substance or behavior. And increased attention to these cues is associated with craving. Methamphetamine is the most abused drug among domestic drug offenders, with continually increasing rates of recidivism. Of the total number of reported drug offenders in the last three years, 21.1 percent have been women. Even so, research on female drug offenders is inadequate, rendering policies and fundamental data for the development of psychotherapy programs insufficient. The present study intended to investigate whether female methamphetamine addicts displayed an attention bias towards drug cues. A dot probe task was conducted on 22 female methamphetamine addicts (addiction group) and 22 non-addicts (control group). The task allowed the correct response rates and correct reaction times of the participants to be calculated according to the positioning of the drug and neutral cues. The analysis results revealed that the control group displayed no difference in correct reaction rates and correct reaction times between the drug or neutral cues. While, the addiction group showed lower correct response rate and slower response time for drug cues in comparison to neutral cues. The results of this study are significant in that it identified the attention bias characteristics toward drug cues of female methamphetamine addicts who were disconnected from drugs.

In this paper, we analyze the result of the Technology Level Evaluation of 'Biochip and biosensor (BB) Technology' consisted of 3 sub-categorized technologies; biochip sensing (BS), lab on a chip and high-efficient customized health care technology. As an analysis tool, authors used a delphi (a repeated survey) and dynamic methodology with technology growth model to overcome limits of previous evaluations. As a result, levels of BB were evaluated 51.5% (Korea) and 75.1% (US), and the technology gap between two countries was 6.1 yrs. In 2013, these levels were expected to change to 60.1% (Korea), 78.4% (US) and 4.3 yrs, respectively. In comparison with other biotechnology, the gap of BB was smaller and expected to catch up with US faster. In the case of sub-categorized technologies, they showed the smallest gap and would have faster catch-up speed than other sub-categorized technologies in the Biotechnology field. Based on the result of the survey, relative superiority of BB in Korea was originated from competent researchers and research fund, but weak basic science would be weak points. We think that BB's characteristic as an emerging technology and concentrated research activities on BB are additional strong points. This research proposes the supporting and supplemented points to promote the BB in Korea.

Technology-driven innovation and job-creation has each been the subject of much scholarly attention, but have largely been considered separately rather than in conjunction with each other. While the previous literature on economics pinpointed the macro effects on industry-level, this study explores the micro-level comparisons on innovation sources over the employment and financial performances. The PSM (propensity-score matching) analysis presents that firms, involved in an inward technology, tend to have higher employees with dominant technology capabilities than in-house R&D firms. The in-house R&D firms, on the contrary, have superior financial performances, suggesting that external technology commercialized firms suffer from low transformative efficiency. The mediation test analysis corroborates that the external technology-driven innovation induces more human resources in internalizing the exogenous technology. The positive relationship between R&D innovation and employment allow verification of the government's intervention in the promotion of technology commercialization in public sector. On the other hand, it also signals that the policy needs to enhance the recipient firms' commercializing capacity rather than a 'one-hit' transaction.

The purpose of this study was to identify the underlying dimensions of push and pull motivators for Soraksan, Kayasan, Naejangsan, and Pukhansan national parks in mountain regions. This study also examined the nature and extent of the reciprocal relationship between the push and pull factors. The result showed that four dimensions were derived from 12 push items, which were cultural and natural experience, escape and rest, health, and socialization and novelty motivators. Three dimensions also were derived from 12 pull items, which were facilities and culture, nature, and accessibility. The push and pull dimensions were correlated and regressed against each other. Given the nature of relationship between the push and pull factors, facilities and culture pull factor was affected by the cultural and natural experience motivation. Nature pull factor had strongly associated with culture and nature, escape and rest, health, and socialization and novelty motivations. Finally, accessible attraction pull factor had a positive relationship with health motivator, however, had a negative with cultural and natural experiencing motivation.
