이 연구에서는 비정형 자료 분석 기법 중 하나인 텍스트 마이닝 기법으로 기상청 연구개발분야 과제의 동향에 대하여 분석하였다. 이를 위하여 용어사전을 구축하고, 전처리를 하여 용어-문서 행렬을 만들었다. 이것을 이용해 연도별 용어 빈도수를 측정하고, 자주 나타나는 단어들에 대해서는 상대도수의 변화에 대해서 관찰하였다. 그리고 회귀 분석을 사용하여 증가추세와 감소추세를 가지는 용어들을 파악하였다. 이러한 분석으로 기상청 최근 연구개발 분야의 트렌드를 파악하였다. 이와 같은 연구는 향후 기상청 연구개발에 관한 기초 자료로 사용될 수 있으며, 연구개발의 방향성과 청사진을 제시하는데 이용될 수 있을 것이다. This paper considers the analysis of patterns in meteorological research and development using a text-mining algorithm as the method of analyzing unstructured data. To analyze text data, we define a list of terms related to meteorological research and development, construct times series of a term-document matrix through data preprocessing, and identify terms that have upward or downward patterns over time. The proposed methodology is applied to multi-year plans funded by Korea Meteorological Administration research and development programs from 2011 to 2015.

항혈소판제를 투여받는 환자의 치과치료

박홍주,Park, Hongju 대한치과의사협회 2019 대한치과의사협회지 Vol.57 No.10

Antiplatelet agent is administered to the patients who have ischemic heart disease, transient cerebral infarction, as well as hypertension, etc. Antiplatelet agent prevents thromboembolism by inhibition of platelet aggregation by various mechanism. Due to that reason, patient who administered antiplatelet agent has bleeding tendency. Surgeon does not want to make a complication by bleeding during and after operation, and want to stop taking antiplatelet agent. However, It is very dangerous for the patient to stop antiplatelet agent. Local bleeding as a complication after operation is considered minor one, whereas thromboembolism is life threatening serious complication. Most dental intervention can be performed without withdrawal of antiplatelet agent. Dental intervention should be limited area, and surgeon should do active bleeding control.

박홍주(Park HongJu),이은아(Lee Euna) 한국여성학회 2004 한국여성학 Vol.20 No.2

이 글은 기혼여성노동자의 일ㆍ가족 경험과 노동시장 내 제반 조건이 이들의 직업의식에 어떤 영향을 미치는지 여성의 경험과 입장을 중심으로 살펴보고자 한다. 기혼여성노동자 278명을 대상으로 일과 가족경험을 조사한 결과, 정규직 기혼여성보다 비정규직 기혼여성의 일ㆍ가족갈등이 더 높고 가족의 정서적 지원은 더 낮게 나타났다. 고용불안정은 노동시장뿐 아니라 가족 내에서도 기혼여성을 불완전 노동자로 규정하는 이중의 효과를 갖는다. 업무전문성과 노동통제 강화는 정규직 기혼여성이 비정규직 기혼여성보다 더 높았으며, 평균교육 년수와 월평균 소득, 생계부양역할과 가족의 정서적 지원, 가족지향성, 그리고 업무전문성이 직업의식에 영향을 미치는 것으로 나타났다. 본 연구 결과는 저임금과 불안정 노동으로 관철되는 여성노동의 특성을 변화시켜야만 여성의 일과 삶의 질을 향상시킬 수 있으며, 이를 위해 기혼여성노동자의 고용안정과 노동자로서의 인정 및 지원이 필요하다는 것을 보여준다. This study aims at examining how the work of married women, their family experiences, and various circumstances in labor market have influenced upon their vocational consciousness. 'Vocational consciousness' has been transformed or reconstructed under specific circumstances not only as a social knowledge system but also a gendered institution which is constructed in a certain social, historical, and cultural context. Although the participation rate of economic activity for married women has been consistently increased, their vocational consciousness has been still represented as 'non-being' or 'deficiency'. For instance, the low level of their vocational consciousness has been generally attributed as a cause for a justified excuse for gender discrimination such as the low employment rate of women, the gender discrimination in retiring age and layoffs. Keeping in mind this problems, this study focuses on the women's work and family experiences through their own voices. To analyze the difference in work and family experiences of the married women workers according to their different employment status, this study surveyed 278 the married women workers asking their work and family experiences. The results from the analysis show that in the family life of the contingent workers of married women, they have higher rate of work-family conflicts, while lower rate of emotional support from their family. The instability of employment has doubly influenced upon married women workers designating them unstable workers in family as well as in labor market. In the aspects of labor experiences, study results reveal that the regular workers of married women have more their work professionality and reinforcement of the labor control than the contingent workers of married women do. It furthermore shows that the factors affecting on their vocational consciousness are the average years of educational attainment, the average incomes, the role of family supporter, the emotional support from their family, the family orientation, and their work professionality. As the dual-earner households have been increased recently, it is recommended that government or employers should establish the practical supporting institutions and systems for married women worker. The implications from the study results indicate that acknowledging the married women as a worker and providing the subsequent supporting system are prerequisite for achieving an employment stability of the married women.

[특집/민주주의하에서 보호받지 못하는 노동/파견직, 여성 그리고 촉탁직 노동자]성별화된 노동시장과 여성노동자의 주변화 -정보통신산업을 중심으로

This study aims at examining how the restructuring in labor market have influenced upon the employment rights and the conditions of female workers. The borderless infinite competition in the age of globalization has transformed or reconstructed not only a gendered labor market but also an intimacy structure which is constructed in the relation between work and family.<br/> Considering all worker as 'workers with a responsibility on the family', it is recommended that government or employers should establish the practical supporting institutions and systems for married women/men worker. For instance, the low level of these systems has been generally attributed as a cause for a justified excuse for gender discrimination such as the low employment rate of women, the gender discrimination in retiring age and layoffs. Above all, the state's deregulation policy has deeply influenced upon the marginalization of female workers and gender discrimination in labor market. Furthermore, it has been caused by the rapid changes of family institution such as rising divorce rates and dramatic decrease in the birth rates, now what is called 'Strike on Birth'.<br/> Nowadays, some researchers are questioning the problem of maginalized professional women in the IT field. Their optimistic view accurately reflects not only the statistical data reporting a increase trends of women, but also the conviction of future code, 'women'. However, with a criticism of this optimistic view, this study attempts to analyze the difference in work and family experiences of the women workers according to their different employment status, the marital status and job. For doing this, this study surveyed 10 married/single women workers asking their work and family experiences.<br/> The results from the analysis show that the instability of employment has doubly influenced upon married women workers designating them unstable workers in family as well as in labor market. The implications from the study results indicate that acknowledging the women as a worker, providing the subsequent supporting system for 'worker with a responsibility on the family', and establishing government policies to deconstruct gender division of labor in local market, are requested in global era. If not fulfilled these essential prerequisite, Women programmers in the IT field would do not continue their job.<br/>

구강암에 대한 외과적 처치로 구강 내 광범위한 경조직, 연조직을 제거한 환자는 저작, 연하, 발음 등의 기능적 문제와 치열, 안모의 심미적 문제를 갖게 된다. 악골 재건 후에도 치조골 등 합병증으로 인해 가철성 보철물의 유지 및 지지를 받는데 제한적이다. 임플란트 지지 고정성 보철물은 이러한 환자들에게 적절한 보철수복 방법이 되어 왔다. 본 증례는 하악 재건 후 computer-aided design과 computer-aided manufacturing을 이용하여 지르코니아 프레임워크 상부에 단일 구조 지르코니아 크라운을 제작하여 현재 치열의 기능적, 심미적 회복을 하여 이에 보고하고자 한다. Defects due to mandibulectomy often cause hard and soft tissue loss and result in esthetic problems and functional disorders such as mastication, swallowing, and pronunciation. After the mandibular reconstruction, several complications including loss of alveolar bone can cause limitations in maintenance or supporting of removable prosthesis. For these patients, implant-supported fixed restorations have been an appropriate prosthetic restorative method. In this case report, we report the patient who underwent mandibulectomy and mandibular reconstruction owing to oral cancer, and then restored the current dentition functionally and aesthetically by applying zirconia frameworks and monolithic zirconia crowns by computer-aided design and computer-aided manufacturing.

본 연구는 식물성 지방 급원이 당뇨 모델의 지질대사에 미치는 영향을 검토하고자 수행하였다. 실험모델은 STZ의 투여로 유발된 인슐린의존형 당뇨 마우스를 이용하였고, 4종류(라아드 10%에 각각 대두유, 쌀눈기름, 쌀겨기름, 참기름 10% 첨가)의 실험식이를 7주간 급여하여 체내 지질 함량 및 대변으로의 배설량을 조사하였다. 그 결과 실험동물의 식이 섭취량과 체중 및 장기 무게는 실험군 사이에 큰 차이가 없었으나, 혈청 중성지방은 쌀눈기름 및 쌀겨기름 첨가군에서 다른 실험군들보다 낮은 경향을 보였고, 간의 총콜레스테롤 함량은 쌀눈기름 첨가군에서 대조군보다 낮은 경향을 보였으며, 간의 총지질 함량도 쌀눈기름 첨가군에서 대조군보다 낮은 경향을 보였다. 그리고 대변으로의 총지질 및 총콜레스테롤 배설량은 쌀눈기름 첨가군과 쌀겨기름 첨가군에서 대조군인 대두유군보다 유의하게 많은 것으로 나타났다. 이상의 결과로부터 쌀눈기름과 쌀겨기름 급여군에서 체내 지질함량이 낮았고 쌀눈기름군에서 쌀겨기름군보다 낮은 경향을 보였다. 그러므로 쌀눈기름은 인슐린의존형 당뇨마우스에서 체내 지질 함량 저하 효과가 있는 것으로 밝혀졌으며, 이는 쌀눈기름의 대변중 총지질 및 총콜레스테롤 배설량 증가와 관련된 것으로 평가되었다. 따라서 쌀눈기름은 대두유나 참기름보다 당뇨병 모델의 체내 지질대사에 개선 효과가 있는 것으로 보인다. This study was carried out to compare the effects of different plant oil sources on lipid metabolism of insulin dependent diabetic mice. Streptozotocin-induced (65 ㎎/㎏ B.W.) diabetic mice were fed four kinds of experimental diets with 20% lipid, which composed of 10% lard, and 10% soy bean oil (SBO), 10% rice germ oil (RGO), 10% rice brab oil (RBO) and 10% sesame oil (SSO) respectively, for 7 weeks. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in diet intake and body weight among experimental groups. But the concentrations of serum triglyceride of RGO and RBO groups, and of serum total cholesterol of RGO and SSO groups were lower than those of the others. The hepatic total cholesterol level was the lowest in RGO group. The contents of total lipid and total cholesterol excreted in feces of RGO and RBO groups were higher than those of SBO and SSO groups. These results suggested that rice germ oil can effectively reduce serum triglyceride level and hepatic total cholesterol concentration of insulin dependent diabetic mice than rice bran oil, soy bean oil and sesame oil, and hypolipidemic effect of rice germ oil be due to increasing fecal lipid excretion. But we need to investigate the more detailed factors on lipid reducing effect in rice germ oil and rice bran oil.
