Purpose: This study examined the characteristics differences associated with 1-year continuous smoking abstinence in Korean young adult and middle-aged male workers. Methods: 'Korea National Health and Nutrition Examination Survey (KNHANES)' is an ongoing surveillance system that assesses the health and nutritional status of Koreans. For a secondary analysis of cross-sectional data from KNHANES VI-1, this study selected 683 Korean male workers as a subpopulation, who were young adult or middle-aged. The subpopulation was composed of success or failure group of 1-year continuous smoking abstinence. Binomial logistic regression analysis was performed. Results: Success group was more likely to be older, live in urban areas, rate their health status as excellent or good, and have ever been diagnosed with hypertension than failure group. Additionally, Success group was less likely to have used electronic cigarettes (e-cigarettes), drink more than once a month, and have been exposed to secondhand smoking in workplace within a week. Conclusion: Developing smoking cessation programs requires consideration of resources in rural areas, promoting self-efficacy, restricting e-cigarettes and drinking, and promoting a smoke-free workplace.

The aim of this retrospective study was to compare the amount of marginal bone loss between upper anterior area and upper posterior area with 71 upper single-tooth restorations on 2 stage machined $Br{{\aa}}nemark$ implants since Jan 1995. The second aim was to compare the bone defect group which had dehiscence and fenetration and the others in the upper anterior region. The results were as follows. 1. The most frequent reason of missing tooth in the upper anterior region was trauma by 61%. While upper posterior region showed various reasons such as congenital missing, advanced periodontitis, trauma. 2. Peri-implantitis with fistula occurred 1 of 41 implants in the upper anterior group in 1 year after loading and 2 of 32 implants in the upper posterior group failed before loading. The 1 year success rate of upper anterior group was 97.56 %, and 93.75 % for upper posterior group. 3. The mean marginal bone loss in the upper anterior group was 0.44${\pm}$0.25 mm, while 0.57${\pm}$0.32 mm in the upper posterior group. There was statistically significant difference in the amount of mean marginal bone loss (P${\pm}$0.10 mm at one year, and 0.48${\pm}$0.26 mm for the control group. No statistically significant difference of mean marginal bone loss was showen between bone defect group and the others at implantation. According to the results, the upper anterior region showed less marginal bone loss than the upper posterior region. In case of missing single upper tooth, careful consideration on recipient residual ridge to determine proper implant diameter and length, sufficient healing time, proper loading would lead to implant success. Single tooth implants in the maxilla seemed to be an alternative to fixed partial dentures without damage to adjacent teeth.

The present study aims to investigate the perceived usefulness of business coaching as a moderator between the association of entrepreneurial competencies and business success of women micro-entrepreneurs. This study employs a stratified random sampling technique to collect data from women micro-entrepreneurs who attended business coaching sessions. In total, 261 questionnaires were distributed and collected. This study has divided the moderator (i.e., perceived usefulness of business coaching) into two groups, namely, group 1 (with a low mean) and group 2 (with a high mean) for moderation analysis. By using a comparative analysis of the path coefficient for groups 1 and 2, the path is moderated by the perceived usefulness of business coaching if the beta value for group 1 is significant, and the beta value for group 2 is non-significant. The results show that eight out of a total of sixteen hypotheses were supported, while the remaining hypotheses were rejected. The findings of the study suggest that the domains of entrepreneurial competencies for women micro-entrepreneurs, including strategic, commitment, conceptual, opportunity, and relationship competencies, together with the perceived usefulness of business coaching, are vital for the business success and should remain the principal focus of future research in women entrepreneurship.

다수의 노드들이 유사한 이동 특성을 보이는 그룹 이동성을 고려하였을 때, 동일 그룹에 속한 노드간의 상대 속도는 작기 때문에 그룹 내 라우팅 업데이트 주기를 길게 설정하여 라우팅 오버헤드를 최소화하는 것이 가능하지만, 수집된 정보의 정확성이 저하되기 때문에 상대 속도가 큰 그룹 간의 패킷 전송 성공률이 감소된다. 그룹 간의 라우팅 오버헤드를 패킷 전송 성공률의 저하 없이 감소시키기 위해 이동 적응적인 라우팅 업데이트 구조가 본 논문에서 제안된다. 제안하는 알고리즘은 각 그룹 단위로 이동성을 예측을 하고 이를 통해 라우팅 업데이트 주기를 유동적으로 조절하여 라우팅 오버헤드를 감소시킨다. 또한 적절한 인접 그룹을 중계(relay) 그룹으로 설정하여, 추후 이동성에 의해 두 그룹간의 직접적인 연결이 단절되더라도 중계 그룹을 통해 통신이 원활이 유지될 수 있도록 지원함으로써 오버헤드가 감소하고 패킷 전송 성공률이 높아지게 된다.

건설산업에 있어 입찰 경쟁력은 기업의 가장 기본적이며 중요한 역량이다. 입찰 경쟁력은 기업이 보유한 경쟁우위에 기인한 것이나, 입찰 경쟁력을 확보하기 위한 기업의 전략은 결국 프로젝트의 특성에 따라 달라질 수 있다. 특히 해외건설은 건설업의 고유성과 해외사업이라는 특수성이 공존하는 분야로, 본 연구는 국내기업들이 도급형 방식으로 실시한 12,952건의 해외 프로젝트 입찰 사례를 수집하여 프로젝트 특성에 따른 입찰 성공률을 분석하고 그 차이를 확인하여 상황별 입찰 난이도를 진단하였다. 분석 결과, 지역별로는 중동 지역에서, 공종별로는 토목 부문이 입찰 성공률이 낮아 입찰활동에 대한 난이도가 높음을 파악할 수 있었다. 또한 프로젝트 규모나 기간이 작은 그룹이 상대적으로 입찰 성공률이 높음을 확인하였고, 입찰방식에 따라서는 수의시담 방식이, 발주자 형태별로는 민간부문 발주 프로젝트의 입찰 성공률이 높은 것으로 분석됐다. 반면 계약방식이나 시대구분의 경우 Kruskal-Wallis test 결과, 그룹 간 기업별 입찰 성공률이 통계적으로 유의미한 차이가 없음을 확인하였다. 본 연구는 산업차원에서 해외건설 프로젝트 특성요인에 따른 입찰 성공률을 다각적으로 분석했을 뿐 아니라 해외건설 실무자에게 상황별 수주활동 난이도 진단 및 효과적인 입찰전략 수립을 위한 기초자료를 제공한다는 점에서 의의가 있다.

This study investigates the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems as TAM insists. Adaptive Structuration. Theory (AST) joins with TAM in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. We found that collected data from 303 individual IT staffs in a national bank. Our results demonstrate that traditional theories on TAM (Technology Acceptance Model) need to be refined, when considering the TTF(task-technology fit). TTF render high influences on PU(perceived usefulness). PEU(perceived ease of use) and FOA(faithfulness on appropriation). And FOA influences highly on our dependent variable. Implications and directions for future research are discussed.

Purpose: To compare the success rates of performing only silicone tube intubation versus carrying out both conjunctival resection and silicone tube intubation. Methods: The subjects of this study involved 62 patients (96 eyes) between October 2015 and May 2017 who were diagnosed as having punctal stricture or nasolacrimal duct stenosis. Out of 96 eyes, 47 underwent only silicone tube intubation, and 49 underwent both silicone tube intubation and conjunctival resection. Three parameters were measured at 1, 3, and 6 months after the surgery: the area of the tear meniscus using RTVue-100 anterior segment optical coherence tomography, the height of the tear meniscus using a slit lamp microscope, and the subjective satisfaction of patients as a result of improved sympotms like epiphora. The surgery was considered successful when the patients' experienced the resolution of symptoms and reduction of the area and height of the tear meniscus. Results: The area of the tear meniscus, height of the tear meniscus, and subjective satisfaction of patients was superior in the group that underwent both silicone tube intubation and conjunctival resection compared silicone tube intubation only. Based on these results, the success rate of the surgery was 68.9% in the group that underwent only silicone tube intubation and 78.7% in the group that underwent both silicone tube intubation and conjunctival resection. Conclusions: The resection of relaxed plica semilunares seems to increase the success rate of silicone tube intubation through the reduction of the area and height of the tear meniscus. Therefore, after determining the degree of conjunctivochalasis, if it was found to be severe, a combination with conjunctival resection was expected to increase the success rate of the surgery.
