A comprehensive analytical method of endocrine disruptors[i.e., nonylphenol(NP), octylphenol(OP), bis(2-ethylhexyl) phthalate(BEHP)] in meat or pork samples was developed. The method employed closed culture tube extraction with dichloromethane and solvent exchange to iso-hexane and SPE(2g) aminopropyl column, followed by determination on gas chromatography linked to mass spectrometry(GC/MS) operated in the single ion monitering(SIM) mode. For the multipoint recovery of nonylphenol, octylphenol and bis(2-ethlhexyl) phthalate OP, NP were showen good recoveries in $0.125-1.25{\mu}g/g$ range of concentration, and BEHP more good recoveries in $0.0125-12.5{\mu}g/g$ wide range of concentration. The present method was applied to beef or pork samples of mart and butcher in Cheonju city and near Cheonju. The range of concentrations was respectively, $0.06-0.24{\mu}g/g$ in nonylphenol(NP) and $0.36-2.35{\mu}g/g$ in bis(2-ethylhexyl) phthalate(BEHP), but octylphenol(OP) was not dected in any samples. This method provides a powerful analytical tool to investigate a wide range of endocrine disruptors in biological samples of limited quantity.

Objectives : The purpose of the study is to obtain the basic data for an industrial oral health project enhancing the quality of life and oral health. Methods : Questionnaire consisted of 17 questions including 7 questions of general characteristics, 5 questions of oral health awareness, and 5 questions of the behavior of oral health. A self-reported questionnaire was carried out from September 1 to September 28, 2012, The subjects were 400 male and female sanitation workers in private corporations in Jeonju. A total of 354 questionnaires were analyzed using SPSS windows ver. 12.0 (SPSS Inc. Korea). Results : The majority of the subjects were male in 50's. Temporary contract workers are older aged and 2 to 5 years of career workers were the majority of the cleaners. Average monthly income was less than 2 million Korean Won. Those who had a higher academic background and permanent position tended to have oral health knowledge (p<0.05). Female workers had healthier subjective oral health status than male workers. Those who were in older age, single, temporary position, and 2 to 5 years of career tended to have healthier subjective oral health status (p<0.05). Those who were in older age, married, and long period of employment were worrying about their health (p<0.05). The subjective oral health knowledge was high in 49.7% of the workers because they were not able to brush teeth during work hours. They were able to brush their teeth only after dinner. It was low in female and older aged workers (p<0.05). The brushing method included a combination of top to bottom and from the side to side. Conclusions : This study showed the influencing factor of oral health in street workers. Work environment, education, age, monthly income, and types of employment were the important factors to oral health care. It is necessary to provide the right oral health care program for the workers in the near future.

In this paper, we investigated the shadow area of radio programs which are currently being broadcast via FM 102.5 MHz in Jeollabuk-do consisting of 6 cities and 8-guns. The field strength data of FM 102.5 MHz was used with criterion of shadow area. As a result, the field strength of the eastern mountainous area in Jeollabuk-do was very low. We also measured, compared and analyzed the field strength of 102.5 MHz(TBN-Jeonju), 100.7 MHz(KBS) and 99.1 MHz (MBC) in Jeollabuk-do. Based on the field strength data, we tried to find what correlation exists and how much influence is between difference of antenna output power and solution of shadow area. In result, enhancement of antenna output power is not solution in terms of reducing the shadow Area of 102.5 MHz(TBN-Jeonju). In addition, we measured, compared and analyzed the field strength of 102.5 MHz(TBN-Jeonju) and 106.9 MHz(EBS). In fact, the relay stations with 104.1 MHz, 104.9 MHz, 105.3 MHz and 107.5 MHz of EBS FM has a number of FM relay stations in the eastern mountainous area of Jeollabuk-do. As a result, we confirmed that EBS almost did not have shadow area in the eastern mountainous area of Jeollabuk-do based on the field strength data. As in the case of EBS and KBS, we suggest installing TBN-Jeonju FM relay station with the best solution to reducing the shadow area to extend the audible range of TBN-Jeonju.

As a result of the survey, Geigisan Mountain is used as a natural place for recreation and leisure of residents of Jeonju. The most important factors in the selection of forest healing programs for visitors were the activities, organization and chronology of the program, and the main purpose was to improve health. Week-by-week programs utilizing weekends were preferred for management of forest healing programs. It was revealed that sports programs prefer to enjoy natural scenery, forest experience programs, healing programs, forest therapy programs, meditation programs, and listening to forest music. The outcome of this study is expected to be used as a basic source for developing and researching a program for forest healing in the area of Mt. Meanwhile, the limit on the composition of suitable forest healing programs according to preference is required for continuous and continuous integrated study of the forest healing program for the future of the forest healing program.

현재 국내에서 ITS(Intelligent Transport Systems) 통신방식으로 이 용되고 있는 DSRC 방식은 TTA(한국정보통신기술협회)의 기술표준으로서 대전시,전주시에 적용되어 BIS(Bus Information Service)에 이용되고 있고,최근 고속도로 ETCS(Electronic Toll Collection System)가 DSRC방식으로 전국고속도로 Tollgate 에서 2007년 연말에 개통될 예정이다. DSRC 방식은 2000년에 TTA(한국정보통신기술협회)에서 기술표준이 제정되어 현재 1Mbps 의 Data 용량을 가진다. DSRC 방식의 물리링크 변조방식은 ASK(Amplitude Shift Keying)로 ITS 확장 서비스 적용을 위해 변조방식을 QPSK(Quadrature Phase Shift Keying )로 개선하게 되면 이론적으로 4배의 Data Rate 향상이 이루어진다. 물리적인 RF 변조방식을 ASK에서 QPSK로 바꿔 간단히 Data Rate을 개선하게 되면 회로구현의 경제성이 향상되어 DSRC 응용 서비스가 활성화 될 것이다.
