본 연구는 자동차 부품 기업이 수출다변화 전략을 수립함에 있어서 고려할 영향요인과 전략의 중요도와 우선순위를 분석하였다. 기업의 수출다변화 전략은 기업이 보유하고 있는 내부 역량과 외부 환경을 중심으로 결정되어 왔다. 선행문헌을 리뷰하고, 전문가 6명을 대상으로 인터뷰를 실시하였다. 문헌 리뷰와 인터뷰 결과를 교차분석하여 영향요인을 선정하였으며, 다기준 의사결정 기법인 AHP(Analytic Hierarchy Process)을 활용 분석하였다. 설문조사는 수출업무경험을 갖고 있는 자동차부품기업 재직자 87명을 대상으로 전자메일 및 직접조사를 통해서 수행하였고, 최종 68명의 설문이 유효하였다. 이를 분석한 결과, 영향요인들의 상대적 중요도와 우선순위를 결정하였다. 영향요인간 쌍대비교를 하고 이들의 상대적 중요값을 결정하였다. 그리고 대안으로는 Porter(1985)의 본원적 경쟁전략 이론을 근거로 하였다. 분석결과, 중요도는 평균적으로 내부역량, 상호관계, 구매자 영향, 진입장벽, 기술력 대응, 경쟁환경 순으로 나타났다. 해외 브랜드 수준이 높은 권역은 제품차별화, 저원가, 집중화 순이며, 수준이 낮은 권역은 저원가, 제품차별화, 집중화 순으로 나타났다. 본 연구결과는 자동차부품 중소기업이 수출다변화 전략 채택을 위한 대안을 마련하여 상황에 맞는 전략을 수립할 수 있다는 것에 의미가 있다. 자동차부품 수출다변화는 세계권역별 다양한 특성의 맞춤형 전략 수립이 필요하며, 또한 수출다변화를 위한 내부역량 뿐만아니라 동시에 현지 구매자와 그 상호관계가 중요한 것으로 분석되었다. This study analyzed factors that should be considered in the process of export diversification strategy formulation and priorities of strategies. We reviewed the extant literature and interviewed six experts. Cross-sectional analysis of a literature review and interview results were used to determine the influencing factors of export. The data for this study were collected from a survey of 68 export experts in Automotive Parts enterprises. Data were analyzed using AHP. As a result of the analysis, the order of importance appeared in the order of internal capacity, correlation buyer effect, entry barriers, technology response, and competition environment. The regions with a high overseas level were product differentiation, centralization, and low cost, whereas those with a low level were in the order of low cost, product differentiation, and concentration. It is meaningful to review the alternatives for adoption of the export diversification strategy and establish a strategy appropriate to the situation. It is necessary to establish a customized strategy considering the characteristics of the global region, and not only internal competence but also mutual relationship with local buyers are important.

In this research, properties of $N_2$-doped $Sb_2Te_3$ thin film were evaluated using 4-point probe, XRD and AFM. $Sb_2Te_3$ material has faster crystallization rate than $Ge_2Sb_2Te_5$, but sheet resistance difference between amorphous and crystallization state is very low. This low sheet resistance difference decreases sensing margin in reading operation at PRAM device operation. Therefore, in order to overcome this weak point, $N_2$ gas was doped on $Sb_2Te_3$ thin film. Sheet resistance difference between amorphous and crystallized state of $N_2$-doped $Sb_2Te_3$ thin film showed about $10^4$ times higher than Un-doped $Sb_2Te_3$ thin film because of the grain boundary scattering.

N/A We analyzed Radioisotope scan findings of 46 patients of thyroiditis which were proven pathoiogically at K.C.FI. The results were as follows 1) 45 patient.s were female, one was male and average age of patients was 37 years old. 2) The lesion site was predominant in both lobe (67%) Hashimotos thyroiditis showed enlarged thyroid (85%) with cold nodule (20%), diffuse decreased activity (10%), while subacute thyroiditis was presented absent activity (53%), poor visualization (20%) or cold nodule (7%). 4) Radioisotope scan was valuable in evaluationg function of thyroid gland and detection of lesion but there was a limit of pathological nature.

Background/Aims: The aim of this study is to assess serum procalcitonin (PCT) for early prediction of severe acute pancreatitis compared with multiple scoring systems and biomarkers. Methods: Forty-four patients with acute pancreatitis confirmed by radiological evidences, laboratory assessments, and clinical manifestation were prospectively enrolled. All blood samples and image studies were obtained within 24 hours of admission. Results: Acute pancreatitis was graded as severe in 19 patients and mild in 25 patients according to the Atlanta criteria. Levels of serum PCT were significantly higher in severe acute pancreatitis (p=0.001). The accuracy of serum PCT as a predicting marker was 77.3%, which was similar to the acute physiology and chronic health examination (APACHE)-II score, worse than the Ranson score (93.2%) and better than the Balthazar CT index (65.9%). The most effective cut-off level of serum PCT was estimated at 1.77 ng/mL (AUC=0.797, 95% CI=0.658-0.935). In comparision to other simple biomarkers, serum PCT had more accurate value (77.3%) than C-reactive protein (68.2%), urea (75.0%) and lactic dehydrogenase (72.7%). Logistic regression analysis revealed that serum PCT has statistical significance in acute severe pancreatitis. Assessment of serum PCT levels and length of hospital stay by simple linear regression analysis revealed effective p-value with low R square level, which could make only possibilty for affection of serum PCT to admission duration (r2=0.127, p=0.021). Conclusions: Serum PCT was a promising simple biomarker and had similar accuracy of APACHE-II scores as predicting severity of acute pancreatitis. (Korean J Gastroenterol 2011;58:31-37)
