The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.

This study was investigated the subjects' satisfaction in the therapy among the internet age. The subjects of the study were 200 women who have menses in ages from 18 to 55 among visitors of five public health centers and attendants of A church in Gwangju. The period of the study ranged from September 6 to October 10, 2010. As a study instrument, this study used a questionnaire developed based on questions from studies published by An Seung-duk(2003). This study used SPSS 17.0, for a frequency analysis, a cross-tabulation and a chi-squared test. During the analysis, 43.4% of the subjects used the complementary alternative therapy. 56.3% visited used oriental medical clinics or herbal medicine shops as places to use the therapy, 42.5% received medicine, acupuncture, moxibustion and cupping at oriental medical clinics. As expenses of the therapy, 56.3% spent less than 500,000 won a year. After the therapy, 51% answered they were satisfied with the therapy. In conclusion, it was discovered that use rate of the therapy is increasing, the subjects decided to use the therapy for themselves or through recommendation from acquaintances, and they mainly depended on reliable oriental medical clinics or folk remedies against menstrual pain, and insurance benefits for the therapy should be considered except oriental medical hospitals or clinics.

For the scenario of open pit mining, at present, manual periodic verification is mainly carried out in China with the help of video surveillance, which requires continuous investment in labor cost and has poor timeliness. In order to solve this difficult problem of early warning and monitoring, this paper researches a spatialized algorithmic model and designs an early warning system for open-pit mine transboundary mining, which is realized by calculating the coordinate information of the mining and extracting equipments and comparing it with the layer coordinates of the approval range of the mines in real time, so as to realize the determination of the transboundary mining behavior of the mines. By taking the Pingxiang area of Jiangxi Province as the research object, after the field experiment, it shows that the system runs stably and reliably, and verifies that the target tracking accuracy of the system is high, which can effectively improve the early warning capability of the open-pit mines' overstepping the boundary, improve the timeliness and accuracy of mine supervision, and reduce the supervision cost.

In this paper, we have been developed the software in order to ostinato for spill over for TV broadcasting signals between Korea and Japan and analyzed those signals using APD curve. In Busan, we have been measured channel of Japan TV broadcasting signals during 9 months from February 2006 to October 2006. That system has been controled and translated the measured data to remote-control place. Finally it has computation and compared in the APD curve using ITU-R P.1546.

The purpose of this study is to identify the effect of ear acupressure therapy on premenstrual syndrome of the female college students. This research design of our study was a quasi-experimental design. Out of the 27 female college students, 13 were assigned to the experimental group and 14 to the control group. The data was obtained over 3 months from K college located in G city. The use of instrument to assess the premenstrual syndrome is Keele's VAS(Visual Analogue Scale) with the opening records. The subject of the experimental group received the ear acupressure therapy for 3 times for 60 days and the other control group did not get the ear acupressure therapy treatment. We analysed the data and extracted the values of percentage, mean, standard deviation, $x^2$-test, t-test, and Cronbach's ${\alpha}$ using SPSS program. The VAS score of the premenstrual syndromes before the ear acupressure therapy was 7.3(experimental group), 7.46(control group) but after the ear acupressure therapy, the VAS score of the premenstrual syndromes was 3.36(experimental group), 7.17(control group). The result of this study reveals that the ear acupressure therapy was effective in improving the symptoms of the female college students who had the premenstrual syndromes.

In this study, we have been constructed measuring system for spill over by the Japan TV broadcasting signals and analyzed those signals using APD curve. In Busan, we have been measured channel of Japan TV broadcasting signals during 9 months. The quality of image is that maximum grade is 2.5 level, and the quality of sound is that maximum grade is 3 level. In the result of analysis for measured Japan TV broadcasting signals, we have been observed Japan TV broadcasting signals those we have been chosen the ch 36 and ch 38, plotted the APD curve of each channel for a season, in Specially.

본 고는「특집: 여러 가지 초정밀기술을 응용한 옵토메카트로닉스부품화기술」이라는 주제로 일본 광기술콘택트지 (Vol. 42, No. 12(2004년), 637~641쪽)에 게재됐던 카사이 도시오(河西敏雄)씨가 기고한 내용을 번역, 정리한 것으로 초정밀기술과 옵토메카트로닉스부품의 현황과 과제에 관해 간단히 논하였다. 산업계에서 신문보도등에 의하면 교또의정서의 발효는, 러시아의 기준에 의해 2005년 2월경이라고 한다. 지금까지 앞서간다고 여겨져 왔던 엄한 CO가스의 삭감규제가 드디어 아주 가깝게 대두되었다. 환경문제로 지구온난화를 조금이라도 억제하려는 기업 노력이 추진되어 왔지만, 금후의 초정밀기술 및 옵토메카트로닉스부품·시스템에 대해서도 이를 염두에 둔 새로운 기술전개가 시작될 것으로 예상된다.

황사에 대한 연구는 발원지, 이동경로, 기상조건, 에어로졸의 특성 등 다각적인 면에서 조사되어 왔다. 우리나라에 영향을 미치는 황사현상은 중국 및 몽고 사막 등에서 봄철 기온 상승으로 한랭전선을 동반한 저기압이 발달되어 전선 후면의 강풍과 함께 황토 먼지가 매년 3∼5월경에 편서풍을 타고 3,000 km 이상의 거리를 이동하여 한반도에 유입되는 현상이다. 황사발생일수는 일년에 3∼6일로 주로 4월에 관측되며, 중국의 자료에서도 연중 25 %가 4월에 발생한다고 보고하고 있다(Parungo et al., 1994). (중략)

우리나라는 위도상 중위도 편서풍대에 위치하고 있어 황하유역과 중국 및 몽고사막 등에서 발생한 토양먼지가 매년 3-5월경에 편서풍을 타고 1,500-2,000km 이상의 거리를 이동하는 황사와 같은 대기오염 물질의 장거리 이동현상이 매년 발생하고 있다. 장거리 이동되는 황사의 성상은 발원지에서의 토양성분 이외에도 이동과정 중에서 오염된 지역의 가스상 물질들이 추가되고 가스와 입자의 상호작용에 의해 황산염이나 질산염 등이 많이 생성된다. (중략)

Using data from the Economically Active Population Survey: Supplement by Employment Type, This paper examines the effects of the 2007 Act on the Protection of Fixed-term and Part-time Employees on employment levels. Since the Act is applied to only individuals below 55 years of age, we restrict the analysis sample to men whose ages are close to 55 at the time of the survey. For such a sample, the empirical analysis combines regression discontinuity design with a difference-in-differences. The results suggest that the employment effect of the 2007 Act takes a U-shape. The results suggest that the employment effect of the 2007 Act takes a U-shape. The negative effect of the Act was largest around August 2008, a year after it took effect. The negative effects on employment faded away toward August 2009.
