Following the social consensus for the need to stop sexual violence, the government has amended juvenile sex protection laws to impose fees on education practitioners who do not report sexual crimes against women, and amended the 'domestic violence prevention and victim protection laws' (2012. 2) so that the police can investigate on site. However, regardless of these wide efforts, the reality is that sexual crimes against the socially weak do not seem to be dwindling, raising concerns of the effectiveness of such amendments. Generally sexual crimes are hard to prove, and even if reports are filed, most cases are dropped with non-prosecution disposition. Victims are usually limited to women and children and this leads to secondary victims. As this thesis states, developed countries have a more systematic protection methods than our country. Therefore, the purpose of this thesis lies on the construction of public safety infrastructure for the protection of sexual abuse victims (enhancing safety protocols with related organizations, implementing a bill of rights for the victims, prevention-centered police education, amendments to current law) to limit human rights violations and criminal injuries.

The definition of 'critical cancer' in critical insurance(CI) is more insurance meanings than medical meanings. The difference between critical cancer of insurance and critical cancer of medical cancer is made difficult problem to the underwriting of insurer, contractor and medical doctor. The limited factors of underwriting in critical cancer of critical insurance as follows: (1) the limitation factors in the definition of 1st item critical cancer in CI 1) the definition differences of meanings in insurer, contractor, and medical doctor 2) the meanings of "the table of malignance" 3) the definition difference between 'critical cancer' and 'a large of medical expense cancer' (2) the limitation factors in the definition of second item critical cancer in CI 1) The limitation in the change of cancer character 2) The missing malignancy in pathological result due to localized cancer 3) The differences in the test result of hospital (3) the limitation factors in the definition of third item critical cancer in CI. 1) the lower items disobey the higher items 2) clinical malignancy of benign cancer pathologically 3) others: (1) low grade of malignant melanoma (2) early prostate cancer. (3) malignancy related HIV (4) all skin cancer excepted malignant melanoma (5) accepted clinically and a medical certificate by medical doctor as critical cancer of premalignant lesion, carcinoma-in-situ, and borderline cancer.

Objectives : Spinal cord compression is a rare presentation of non-Hodgkin's lymphoma(NHL), occurring in 0.1% to 10.2% of patients. Primary spinal extradural NHL, i.e. occurring in the absence of any detectable extraspinal lymphoproliferative disorder, has a potentially favourable outcome if diagnosed and treated early. The authors describe two patients with a clinical picture of acute spinal cord compression as the first presentation of NHL. Methods : The patients were 48-year-old female and 27-year-old female. Both presented with back pain followed by acute paraparesis and voiding difficulty. One patient was diabetic. Plain radiographs of the spine were not specific. Thoracic spine magnetic resonance imaging(MRI) revealed evidence of extradural soft tissue mass extending multiple vertebral segments. Results : The patients underwent emergency laminectomy for decompression and tissue diagnosis. Histological and immunohistochemical study revealed B-cell lymphoma, intermediate grade in both patients. Postoperative staging did not reveal any additional lesions other than extradural manifestation of the malignant lymphoma. Surgery with additional chemotherapy and radiotherapy allowed the clinical improvement of both patients. Conclusion : The authors report two patients with a clinical picture of acute spinal cord compression as the first presentation of NHL, and stress that primary spinal epidural NHL should be a diagnostic consideration in the patient without prior history of malignancy who presents with a prodrome of back pain followed by a rapid neurological deterioration.

우리나라는 도시화, 산업화에 따른 수질저하 및 용수확보 문제를 해결하기 위하여 각종 환경기초시설의 증설과 수질개선을 위한 대책을 수립하여 왔다. 그러나 점오염원에 국한한 수질개선은 한계가 있었으며, 1995년 환경부는 전국 비점오염원 조사를 통해 비점오염원이 수질오염에 기여하는 비율이 T-N, SS는 50% 이상을 점유하고 기타 BOD, T-P도 $20{\sim}30%$ 수준임을 밝힌 바 있다. 이에 정부는 오염총량관리제를 도입하여 비점오염원의 관리를 시작하였으나, 강우시 정확한 유량자료를 바탕으로한 수질 측정자료의 부족으로 비점오염원 관리에 있어 어려움이 따르고 있다. 따라서 본 연구에서는 비점오염원 관리 및 연구를 위한 기초자료로 활용될 수 있도록 수도권 및 인근지역 주민의 식수원인 팔당호로 직유입되고, 정확한 수질자료 확보가 필요한 경안 수위관측소 지점에서 2007년 6월${\sim}$9월에 일어난 강우 중 4개의 강우사상에 대하여, 수질측정을 실시하였다. 본 연구에서 이용한 유량자료는 2007년 수위-유량관계곡선식으로 산정한 환산 유량이며, 실측한 수질자료를 바탕으로한 유량과 부하량의 관계는 통계학적으로 분석하였다. 수질측정 항목은 수온, DO, pH, EC, SS, BOD, CODMn, CODCr, T-N, T-P 등이며, BOD의 농도는 2개의 강우사상에서만 분석하였다. 현장에서 휴대용미터를 이용하여 수온, DO, pH, EC를 측정하였고, 나머지 항목은 한국건설기술연구원내 환경정밀분석 센타에 의뢰하였다. 각 항목별 유량-부하량 관계식은 기존의 지수식이 아닌 선형이나 다항식으로 산정하였다. 다항식으로 산정된 식의 결정계수($R^2$)는 BOD, T-N 항목을 제외한 각 항목에서 0.6 이상의 값을 가졌다. 항목별로 보면 SS는 0.90, $COD_{Mn}$은 0.87, $COD_{Cr}$은 0.84, T-P는 0.62의 값을 가졌다. 또한, T-N은 0.53, BOD는 0.32의 값을 가져 유량과 부하량의 관계가 거의 상관성이 없는 것으로 나타났다. BOD의 경우는 4개의 강우사상 중 2개의 강우사상에서만 분석되어 다른 항목에 비해 실측자료가 부족한 관계로 그 특성을 판단하기 어려웠다. 본 연구가 주로 홍수기에 이루어져 실측자료가 많지 않았기 때문에 본 연구의 대상지점을 대표할 수 있는 유량-부하량 관계식으로는 미흡한 한 것으로 분석되었다. 본 연구자료를 기초로 장기간 많은 자료를 확보하여 유량-부하량 관계식을 수정 보완한다면, 차후 비점오염원 관리의 기초자료로 활용될 수 있을 것으로 판단된다.

This study involves an analytical approach to determine transit dispatching schedules (headways) Determining a time schedule is an important process in transit system planning. In general, the transit headway should be shorter during the peak hour than at non-peak hours for demand-responsive service. It allows passengers to minimize their waiting time under inelastic, fixed demand conditions. The transit headway should be longer as operating costs increase, and shorter as demand and waiting time increase. Optimal headway depends on the amount of ridership. and each individual vehicle dispatching time depends on the distribution of the ridership. This study provides a theoretical foundation for the dispatching scheme consistent with common sense. Previous research suggested a dispatching scheme with even headway. However, according to this research, that is valid for a specific case when the demand pattern is uniform. This study is a general analysis expanding that previous research. This study suggests an easy method to set a time table without a complex and difficult calculation. Further. if the time axis is changed to the space axis instead, this study could be expanded to address the spacing problems of some facilities such as roads. stations, routes and others.

This research is primarily intended to develop a decision-making support system about the natural environment in the country by integrating various formats of spatial data into a comprehensive GIS database. The first part of the research is to design GIS database as a means of combining thematic cartographic data with field survey records. Ecosystem records acquired by a field sampling have been reproduced as digital thematic maps. The database also included various natural environment related data (map for forestry, soil, national park etc.) collected from many other agencies. The second part of the research is devoted to the design of efficient man-machine interfaces. A key concern in the GUI (graphic user interface) design process was to address the need to handle and to manage large databases by non-GIS experts. The system has been checked experimentally, enabled the users to quarry the data required simply and execute spatial analysis accommodating versatile alternatives in decision-making process. Detailed visual maps can be generated over large areas quickly and easily. The system will serve to increase the scientific and objective decision-making by overcoming serious constraints suffered from the past non-GIS-based approach. It is anticipated that this research output could be used as a valuable reference in building a nationwide natural environment GIS-DB (database) in the central and local governments.

The Hmong people are one of the largest ethnic groups in Vietnam. They traditionally practice shifting cultivation for their daily subsistence. This group has a traditional governance system as well as strong clan and kinship relationships that occupy an important role in maintaining Hmong culture and livelihoods. The state's approval of the legitimate and statutory law for the Nature Reserve largely excluded local rights of access to and the use of natural resources. This study focusses on Hmong responses to the state interventions of the establishment of the Nature Reserve as well as forest land allocation. Based on Scott's contribution of Moral Economy (1976), the authors argue that local responses function as a 'risk-averter' against state intervention. Meanwhile, the intra and inter-ethnic relationships based on the 'subsistence ethic' help locals successfully mitigate state intervention. These findings help the state rethink their interventions, which have been constructed with very little respect for local differences or the desires of ethnic peoples. Furthermore, the main findings, which reveal that not only the intra-ethnic relationship but also the inter-ethnic relationship among ethnic minorities can play an important role in maintaining the Moral Economy, are expected to deepen the previous understanding on the Moral Economy, which has previously constrained its scope to the intra-ethnic relationship.

Background: In malignancies, detection of metastatic foci is of value in making therapeutic plans for treatment of disease and prevention of life-threatening complications. Common sites for metastasis of bronchogenic cancer include lymph nodes, liver, brain, adrenals and bone. Skull, vertebrae, ribs and long bones are common sites for bone metastasis. But in epidermoid carcinoma, the incidence of bone metastasis is relatively low and especially to the distal phalangeal bone is rare. Methods: We experienced a case of epidermoid carcinoma with the first distant metastasis to the fifth distal phalangeal bone, right toe. Results: The initial stage in the diagnosis of epidermoid carcinoma was T4N3MO. During the third round of anticancer chemotherapy, we recognized the distant metastasis to the fifth distal phalangeal bone for the first time. Localized abnormal findings were noted by bone X-ray and scanning. By a histopathologic examination of the amputated toe, we confirmed the metastasis of epidrmoid bronchogenic carcinoma. Conclusion: If localized abnormal finding is discovered at an unusual site for metastasis, we recommend physicians to consider the possibility of metastasis even though it is very low.

As one of the most serious health risk factors, air pollution can no longer be ignored. Particulate matter (PM) is an important and harmful component of air pollution that originates from a variety of sources. Numerous recent studies have linked PM to a range of conditions including cancer, cardiovascular, respiratory, and skin disease. The eye, despite being directly exposed to air pollution, has been investigated in very few of these studies. In this review, we describe the evidence from in vitro and in vivo studies, as well as epidemiological investigations, that supports the association between exposure to PM and the development of ocular conditions such as surface and retinal disease and glaucoma. Based on the results of previous studies, we suggest that PM exposure can lead to oxidative stress, inflammation, autophagy, and, ultimately, ocular surface disease. Nevertheless, almost no studies focus on ocular surface damage from PM while some epidemiological and clinical studies report on the posterior of the eye. However, the underlying pathological mechanisms in the posterior following PM exposure have yet to be identified, and further studies are therefore warranted of the ocular surface as well as the posterior part of the eye.

Propagating waves (flexural, longitudinal and shear waves) travelling with constant amplitudes and evanescent waves decaying exponentially are generated on a cylindrical shell. Evanescent waves are generally generated in the vicinity of an vibration excitation point and near ends of the shell. But the evanescent waves can generates strong axial vibration at the ends of the cylindrical shell. The strong end axial vibration due to those evanescent waves has been observed in an author's previous paper dealing with measurements of the in-plane axial vibration of a finite cylindrical shell. In this paper the strong end axial vibration due to the evanescent waves has been theoretically analyzed. In order to analyze the vibration of the cylindrical shell, wave propagation approach has been implemented. Comparison between theoretical and experimental results for the axial vibration of the shell showed that the strong evanescent wave can be generated due to mode conversion (conversion from flexural wave to evanescent wave) at the ends of cylindrical shell. It also showed that the evanescent wave can generate the strong axial vibration near the ends of the cylindrical shell and that it can have effect even on 1/3 of the total length of the shell.
