This research investigates the export strategy for pioneering a new market of Advanced Pilot Trainer T-50, a business unit of KAI company, and increasing its market share. The export strategy is proposed based on the Corporate Marketing Model along with the market oriented concept. Specific sales strategies are extracted in consideration of product analysis, market analysis, and integration of product and target market. Therefore, six countries in Africa are selected as the primary target markets on account of their market potentials. In addition, T-50 is repositioned to 'T-50Af' as 'high price competitive and multi-role trainer.' The business implications include the expansion of the market in Africa and the pursuit of the consistent development and growth of T-50.

한국인의 대표적인 성인 고형 종양인 위암, 간암, 유방암과 소아 백혈병 및 2종의 소아 고형 종양 환자로부터 혈장 transforming growth factor-β1 (TGF-β1) 농도를 sandwich ELISA 분석법을 이용해 측정함으로써 TGF-β1을 이 질환들에 대한 새로운 종양표지자 (tumor marker)로 사용할 수 있는지 검토하였다. 또한 연령 및 성별에 따른 혈장 TGF-β1 농도의 정상치를 조사하였다. 신생아에서 70대까지 혈장 TGF-β1 농도의 차이는 없었고 남녀간의 차이도 없었다. 위암 환자의 혈장 TGF-β1 농도는 16.0±6.8 ng/㎖ (평균±표준편차)로 정상 대조군의 TGF-β1 농도 (8.3±5.0 ng/㎖) 보다 유의하게 높았으나 간암, 유방암 환자의 혈장 TGF-β1 농도는 대조군과 차이가 없었다. 그리고 위암 환자 16명, 간암 환자 8명, 유방암 환자 7명 중 각각 7명 (43.7%), 1명 (12.5%), 1명 (14.3%)에서만 혈장 TGF-β1 농도가 증가되었다. 5명의 소아 백혈병 환자에서는 관해 (remission) 여부와 상관없이 혈장 TGF-β1 농도가 모두 정상 범위에 있었으나 2명의 소아 고형암 환자에서는 종양 절제 전에는 혈장 TGF-β1 농도가 높았다가 절제 후 정상으로 떨어졌다. 결론적으로 1) 정상인의 혈장 TGF-β1 농도는 연령 및 성별에 따른 차이가 없다는 것을 알 수 있었고, 2) 성인 고형암인 위암, 간암, 유방암에서는 낮은 민감도로 인해 TGF-β1을 진단을 위한 선별 검사로 이용하기에는 부적절한 것으로 판단되었으며, 3) 정상 대조군보다 혈장 TGF-β1 농도가 높았던 위암 환자와 종양 절제 전후로 혈장 TGF-β1 농도가 민감하게 변했던 소아 고형암 환자에 대해서는 향후 표본 수를 늘려 부가적인 연구를 해야 할 것으로 사료된다. To evaluate the usefulness of transforming growth factor-β1 (TGF-β1) as a new tumor marker, we determined the plasma TGF-β1 levels using sandwich ELISA assay in cancer patients. Patients with three most common adult cancers in Korea (stomach, liver and breast cancer) and children's cancers (leukemia and two kinds of solid tumor) were enrolled for the study. Furthermore, 39 individuals were subjected to age and sex-stratified plasma TGF-β1 analysis. No statistical difference was demonstrated with respect to age or sex. The mean plasma TGF-β1 level (16.0 ng/㎖) of stomach cancer patients was significantly higher than that (8.3 ng/㎖) of controls. However, there was no difference among the mean plasma TGF-β1 levels of liver, breast cancer patients and controls. Seven of 16 patients (43.7%) with stomach cancer, one of 8 (12.5%) with liver cancer, and one of 7 (14.3%) with breast cancer showed higher TGF-β1 levels compared to controls. Plasma TGF-β1 concentrations of five leukemic children remained in the normal range regardless of the remission state. In contrast, initial high TGF-β1 levels from two children with solid tumors returned to normal range on surgical resection of tumors. From the above results, we could conclude that plasma TGF-β1 levels of apparently healthy individuals seem to be rather constant irrespective of difference in age or sex, and the plasma TGF-β1 has the limited value as a screening test for the diagnosis of aforementioned adult cancers because of its low sensitivity. Finally, additional studies need to be pursed for the large number of stomach cancer and pediatric solid tumor patients in order to reach a secure conclusion on the usefulness of plasma TGF-β1 as a tumor marker in these patients.

The data were obtained from 320 male and female ``C`` university students in Daejeon in October of 2010. The data were analyzed by descriptive statistics, factor analysis, reliability analysis, regression analysis using the SPSS-WIN 15.0 and AMOS 7.0 program. The results were as follows. First, corporate social responsibility consists of five dimensions: community/cultural service, social contribution, environmental protection, consumer protection/legal responsibility, and economic responsibility. Purchase intention consists of comparative purchase and priority purchase. Second, social contribution, consumer protection/legal responsibility, and economic responsibility affect the corporate image. Third, social contribution and consumer protection/legal responsibility also affect purchase intention. Forth, the corporate image affects purchase intention.

Objectives : The objective of study is to investigate the relationship between the satisfaction of dental service, value quality, and reuse intention among dental implant patients. Methods : A self-reported questionnaire was filled out by 316 dental implant patients in 4 dental clinics in Daejeon from December, 2013 to March, 2014. Results : The average of dental service satisfaction was 4.14(SD=.562). The average of value satisfaction was 3.88(SD=.648), and that of reuse intention was 3.98(SD=.662). The tangibility was defined as the influence of the quality of medical service on the value satisfaction(t=4.042, p<0.001) and the confidence(t=2.997, p<0.01). The influence of the service value on the intention to reuse was 0.486(t=10.796, p<.001) of path coefficient. Conclusions : The quality of medical service is decided by the value satisfaction and the intention to reuse including the value satisfaction.

공통 가변성 면역결핍증은 가장 흔한 일차성 항체 결핍증후군의 하나로 많은 환자에서 위장관 증상이 동반된다. 현재까지 전신 스테로이드 치료가 효과적인 것으로 알려졌으나 전신 부작용으로 그 사용이 제한적이다. 경구용 부데소나이드 치료는 전신 부작용 없이 공통 가변성 면역결핍증의 위장관 증상 개선에 효과적인 약물이다. Common variable immunodeficiency (CVID) is the most common symptomatic primary antibody deficiency syndrome and has a high prevalence of gastrointestinal complications. We report the case of a 36-year-old male with CVID who presented with chronic intractable diarrhea and malabsorption. A comprehensive evaluation revealed no secondary causes of his symptoms. He was treated symptomatically without improvement. After receiving systemic steroid treatment, his symptoms improved, but returned soon after tapering the steroid. When he was subsequently administered oral budesonide, his symptoms and quality of life improved; this effect lasted for 20 months without unacceptable side effects. (Korean J Med 2014;86:637-640)

AHP를 이용한 복리후생 선호도에 대한 연구

전지현 ( Ji Hyun Jeon ),하성욱 ( Seong Wook Ha ) 한국인적자원관리학회 2011 인적자원관리연구 Vol.18 No.1

본 연구는 성별과 직급에 따라 법정외 복리후생 프로그램에 대한 선호도 차이가 있는지를 확인하기 위해서 부산·경남에 위치한 기업에 근무하는 직원들 32명을 대상으로 AHP 기법의 설문조사를 하여 얻은 자료를 바탕으로 실증분석을 수행하였다. 먼저 AHP 기법을 적용하여 각 개인의 법정외 복리후생 프로그램 12개에 대한 상대적 선호도를 계산한 후에, 이러한 각 개인의 선호도가 응답자의 성별이나 직급에 따라 차이가 나는지를 통계적으로 분석하였다. 분석결과를 요약하면, 첫째, 법정외 복리후생 프로그램에 대한 선호도가 성별에 따라서는 상당히 다르게 나타났지만, 직급에 따른 차이는 별로 나타나지 않았다. 둘째, 남자 종업원과 여자 종업원의 선호도는 확실히 차이가 있는데, 남자 종업원은 사택, 임대주택과 같은 주거 프로그램에 대한 선호도가 상대적으로 높았고, 여자 종업원은 본인 교육비 지원, 세부분류-기타와 같은 기타 프로그램, 그리고 동호회 활동 지원에 대한 선호도가 상대적으로 높게 나타났다. 주거 다음으로 두 번째로 선호도가 높은 프로그램인 의료·보건은 남녀간의 선호도 차이가 나타나지 않았다. 마지막으로 본 연구의 이론적, 실무적 의의, 한계점과 추후 연구방향에 대해 논의하였다. This study empirically investigates the preference of employee group among the employee benefit programs based on AHP (Analytic Hierarchy Process) analysis of 32 questionnaires. Employee benefits are various non-wage compensations provided to employees in addition to their normal wages or salaries. On the results of the literature review, this study divides employee benefit programs into four main categories such as housing aid, healthcare aid, entertainment support, and other. Each category is also divided into three subcategories. AHP, which was developed by Saaty(1980), is used to analyze preference of employee among twelve employee benefit programs. This study also statistically analyzes the differences of preference among employee group. Employee group includes gender and rank of employee. Main findings are as follows. The most preferred category is housing aid, and the least preferred one is category-other program. However, there are considerable gender differences in the preference, while there are no distinct rank difference. Women employees prefer some programs such as own education support, entertainment group support, and subcategory-other program, while men employees prefer programs of housing aid category. Therefore, human resource(HR) managers need to design the employee benefit plan, which considers these gender differences in the preference. Finally, theoretical and managerial implications, limitations of this study, and future research directions are discussed.
