Background: Pinch-off syndrome (POS) is a rare complication after totally implantable venous access device (TIVAD) implantation. In cancer patients, it is important to prevent this rare complication and to recognize it early if it does occur. We present a case series of POS after TIVAD implantation and the results of a literature search about this complication. Methods: From July 2006 to December 2015, 924 permanent implantable central venous catheter implantation procedures were performed. The most common indication was vascular access for chemotherapy. Results: POS occurred in 5 patients in our clinic. Two patients experienced POS within 2 weeks, and the other 3 patients were admitted to department of surgery, Istanbul Faculty of Medicine at 6 to 14 months following implantation. The catheters were found to be occluded during medication administration, and all patients complained of serious pain. The transected fragments of the catheters had migrated to the heart. They were successfully removed under angiography with a single-loop snare. Conclusion: POS is a serious complication after TIVAD implantation. It is important to be aware of this possibility and to make an early diagnosis in order to prevent complications such as drug extravasation and occlusion events.

바코드는 상품제조업체 또는 판매원이 자사가 생산, 출하하는 상품의 포장을 디자인할 때 일정공간 바코드 인쇄위치를 포함하여 디자인하는 인쇄방법으로 현재 미국, 일본 등 선진국과 동구권을 포함하여 전세계 84여개국에서 이미 POS시스템을 도입∙활용하고 있다. 우리나라 교역상대국이 거의 포함되어 있기 때문에 국내업체에 대한 해외바이어들의 소스마킹요구가 빈번해지고 있다. 따라서 소스마킹을 하지 않은 경우 거래선 변경을 예고하는 사례도 많아지고 있다. POS시스템의 도입이 급증하고, 최근 POS시스템이 다양한 업태로 그 도입이 확산되면서 국내 유통업체에서도 납품업체에 대해 소스마킹을 요구하고 있고, 소스마킹이 안된 상품에 대한 추급을 기피하는 경향이 높아지고 있는 현재, 바코드와 그 종류에 대해 살펴보도록 한다.

This paper is to reduce implementation time of POS system by applying QFD. All the related elements are classified by the hierarchical structure into three phases: expected quality, weight and evluation. The mentioned about includes the first and second improvement, and the case study of POS system of petrol stations in Taichung. The results of this research are shown in the following. 1. the first improvement was from average 76 days/station to 48 days/station. 2. the second improvement was from average 48 days/station to 36 days/station. 3. the ratio of target achievement was $162\%$

컴퓨터의 주변 장치 중 하나인 마우스는 모니터의 2차원 평면에서 움직임을 인식하여 커서를 움직이는 입력 장치이며, 응용 프로그램을 편리하게 사용하고 다양한 편집을 가능하게 한다. 기존의 아이디/비밀번호 기반 인증 방법에서는 키보드 데이터가 노출되는 취약점이 존재하여 이미지 기반의 마우스 입력을 이용한 새로운 인증 방법이 등장하였지만, 이미지 기반 인증의 취약점 분석 및 실증에 대한 연구는 미비한 실정이다. 따라서 본 논문에서는 마이크로소프트 운영체제에서 제공하는 마우스 위치 추출 API인 GetCursorPos() 함수를 이용하여 마우스 데이터의 노출 가능성을 검증함으로써 취약점을 분석한다.

Part of speech (POS) tagging is an indispensable part of major NLP models. Its progress can be perceived on number of languages around the globe especially with respect to European languages. But considering Indian Languages, it has not got a major breakthrough due lack of supporting tools and resources. Particularly for Odia language it has not marked its dominancy yet. With a motive to make the language Odia fit into different NLP operations, this paper makes an attempt to develop a POS tagger for the said language on a HMM (Hidden Markov Model) platform. The tagger judiciously considers bigram HMM with dynamic Viterbi algorithm to give an output annotated text with maximum accuracy. The model is experimented on a corpus belonging to tourism domain accounting to a size of approximately 0.2 million tokens. With the proportion of training and testing as 3:1, the proposed model exhibits satisfactory result irrespective of limited training size.

Although social work values are stressed among social work educators as well as practitioners, empirical studies on values have been very scarce. The objective of this study is to validate a Korean Version of the Professional Opinion Scale(POS). The Korean version was validated with a sample of 325 social worker working in various types of social work agencies. A series of confirmatory factor analysis suggested that 8 items be removed, resulting in 32 items with 4 factors. The Korean version has the same factor structure as the original version of the POS reported by its developer. The Korean version of the POS are found to be a reliable and valid instrument for measuring social work values. However, validation with more representative samples is needed to improve the quality of the Korean version of the POS.

This paper is aimed at investigating the influence of the learning organization's structural characteristics, learner's characteristics, and perceived organizational support (POS) on organizational knowledge creation. also the POS is tested as a moderator on the relationship between learner's characteristics including learning goal orientation and learning self-efficacy and organizational knowledge creation. the results are as follows. for main effect hypotheses, both connecting the organization to its environment and establishing systems to capture and share learning system representing learning organization's structural characteristics have significant positive impact on organizational knowledge creation. the POS also has a significant impact on organizational knowledge creation. However, learning goal orientation and learning self-efficacy have not significant impact on organizational knowledge creation. for moderating effect hypothesis, POS moderates the relationship between learning goal orientation and organizational knowledge creation, which means if the POS is high then learning goal orientation has more significant positive impact on it. Based on our findings, we conclude that structural characteristics of learning organization provide organizations with an opportunity of knowledge creation. in particular, interconnectedness of organization with environment and organizational knowledge sharing systems determine the ways of behaving that are related to learning within organizations. however, learner's characteristics did not have a significant effect on organizational knowledge creation, which could be interpreted due to the fact that employees are not motivated to create new knowledge if they are rarely required to involve challenging works, generate new knowledge, or share preexisted knowledge with others.

To evaluate the effects of the pelleting and the addition of sodium monensin on production, the chemical and lipid composition of milk and butter physical characteristics, 4 Holstein dairy cows (135 days of lactation) with an average milk production of 14.7 kg/d, were supplemented with a concentrate containing ground canola seeds. The cows were assigned to a $4{\times}4$ Latin square design with a $2{\times}2$ factorial arrangement of treatments: i) ground maize, soybean meal, mineral and vitamin supplements, and ground canola seeds (CG); ii) CG concentrate with 31.5 mg of monensin added per kg of dry matter (DM); iii) CG pelleted concentrate; iv) CG concentrate with monensin addition pelleted. There was no difference in milk production and composition. The addition of monensin increased milk concentration of polyunsaturated fatty acids (PUFA), the PUFA/saturated fatty acids (SFA) ratio, and omega 6. The pelleting increased the concentration of monounsaturated fatty acids, the PUFA/SFA ratio, and the omega 6/omega 3 ratio, but decreased the concentration of SFA. The association between pelleting and the addition of monensin increased the concentration of conjugated linoleic acids by 46.9%. The physical characteristics of butter were not affected by the evaluated diets. We concluded that the concentrate with 31.5 mg of monensin added per kg DM basis combined with the pelleting improves the lipid composition of milk from Holstein cows that are on pasture and supplemented with ground canola seeds, without changing the production, milk composition, and spreadability of butter.
