Purpose - Satisfaction with service is evaluated according to customers' subjective judgment. The expected value of customer service and its evaluations depend on the customers' position. The customer recognizes two different forms of service levels. One is satisfaction and the other is dissatisfaction. Customers who are satisfied want to receive the service in future. However, those dissatisfied try to change the service. The service provider tries to improve the service. There are two different service cycles. One is the successful cycle and the other is the failure cycle. This study aimed to empirically determine the effects of the justice and authenticity of service recovery on customer behavioral intention through an integrated approach to cognitive justice and psychological authenticity. Research design, data, and methodology - Based on a literature review, justice of service recovery was categorized into three types: distributive, procedural, and interactive. Then, authenticity was added to obtain four independent variables, along with recovery satisfaction as a parameter. Behavioral intention, as an outcome variable, was divided into the repurchase intention and positive word-of-mouth. The model and hypotheses were created and measurement items were developed. A questionnaire survey of items concerning the service recovery experience at family restaurants was conducted on college students and residents in Gwangju from September 30 to October 31, 2013. A total of 400 copies of the questionnaire were sent out and 385 were returned. Respondents answered questions about the importance of, and satisfaction with service recovery on a 5-point Likert scale. Excluding 174 copies without service failure experiences and 7 inappropriate copies, 204 copies were analyzed using SPSS 21.0 for Windows and AMOS 20.0 to determine the reliability and validity of measurements. The hypotheses were tested through a goodness-of-fit analysis. Results - First, distributive justice positively affected recovery satisfaction. Second, procedural and interactive justice had no impact. Third, authenticity positively affected recovery satisfaction. Fourth, distributive justice had relatively stronger effects on recovery satisfaction than authenticity. Fifth, recovery satisfaction significantly affected repurchase intention and positive word-of-mouth and it proved effective in mediation. Finally, additional analysis was performed for descriptive statistics of the principal variables by various demographic characteristics and significant differences were found in gender, occupation, and so on. Conclusions - This study has academic significance as the fairness and authenticity of service recovery were investigated to reveal the effects on behavior. The findings could be applied to a wide range of service recovery strategies. However, there are some limitations. First, data was collected only from the residents of Gwangju and most respondents were aged 20-30. Future studies should target a wide range of areas and age groups. Second, because the questionnaire used in this study targets only convenience family restaurants, the results of this study cannot be generalized to all services companies. Future research should be done on a wide range of industries such as hotels, airlines, and hospitals, and perform a comparison between sectors.

Alteration in the syntesis or enhanced inactivation of nitric oxide(NO) can induce impairment of endothelial cell function. Insulin dependent diabetes mellitus(IDDM) is characterized by impaired endothelial function and vascular disease. NO is produced through L-arginine pathway To elucidate the hypothesis that the decreased production on NO in IDDM reflects vascular damage and the NO production can be manipulated by either dietary fat(7% of kg diet) or the oral supplementation with L-arginine(2g/kg bw), plasma markers for vascular endothelial damage and plasma lipid profiles were measured in streptozotocin(STZ)-induced diabetic rats. Diabetic or normal Sprague-Dawley rats were fed 6 different experimental diets for 4 weeks(SO : soybean oil, SOA: soybean oil + L-arginine supplementation, BT : beef tallow, BTA_ beef tallow + L-arginine supplementation, OV olive oil, OVA : olive oil + L-arginine supplementation). Plasma glucose, total cholesterel, HDL-cholesterol, LDL-cholesterol and triglyceride were measured. Endothelial markers, plasma von Willebrand factor(vWf), thromboxane B$_2$, and 6-keto PGF1$\alpha$ of aorta were measured by ELISA. Plasma NO production was evaluated through the measurement of nitrite by EIA. Feeding saturated fatty acid(SFA, BT) increased relative liver size(RLS) in diabetic rats compared to either polyunsatunted fatty acid(PUFA, SO) or monounsaturated fatty acid(MUFA, OV) The supplementation of L-arginine inhibited the liver and kidney enlargement in olive oil find diabetic rats. Plasma glucose was lower in diabetic animal find the olive oil compared to fed beef tallow and the supplementation L-arginine decreased it in diabetic rats find beef tallow significantly(p < 0.05). Plasma TXB$_2$ levels were increased due to diabetes and the value of beef tallow group showed highest value. Plasma vWf concentration of beef tallow group was higher value in normal rats and was elevated more in diabetes. In diabetic groups, the vWf concentration of olive oil group was lower than beef tallow or soybean oil group. The supplementation of L-arginine in diabetic rats decreased plasma TXB$_2$ and vWf levels significantly(p < 0.05). NO production was higher in normal olive oil fed rats and was tend to be decreased in diabetic rats and the supplementation of L-arginine recovered to normal value(p < 0.05), Olive oil supplemented with L-arginine tended to lower plasma total cholesterol and LDL-cholesterol after 4 week treatment. These results suggest that generalized vascular endothelial changes based on plasma TXB$_2$and vWf occurs in diabetic rats. and olive oil with L-arginine supplementation contributes to a better control of the hyperglycemia, endothelial changes and hypercholesterolemia accompanying diabetes as compared with beef tallow or soy bean oil in this rat model.

용선계약에서 정박기간은 확정할 수도 있고 미확정인 상태로 그 항만의 관습적인 방법에 따라 선적 및 양하를 행하는 것이 일반적인 관례이다. 항만설비나 기타 제반 여건이 좋아 하역작업이 조속히 이루어 질 수 있는 상황이라면 선주는 그 항만의 관습에 따라 행하는 하역작업을 허용할 수도 있으나, 항만이 신설되거나 여건이 좋지 않을 경우 일정한 기한 내에 작업을 행하도록 용선 계약상에 명문화 하는 것이 통상적인 운송계약방식이다. 그 이유는 용선자나 선주가 조속한 하역작업을 위해 각자의 권리와 의무에 최선을 다하고, 가능한 조속히 하역을 완료하여 선박이 항만에서 체류하게 되는 시간을 최소화시켜 운항효율성을 제고하는 한편, 그에 따라 운임과 항만비용 등 제반 운송비용을 절감함으로써, 용선자나 선주가 공동의 이익을 실현할 수 있기 때문이다. 이러한 기한부 하역조건에는 용선계약의 양식과 화물의 종류 등에 따라 매우 다양하게 표한할 수 있다. 그러나 이러한 용어에 관하여 용선자나 선주의 명확한 이해부족으로 많은 분쟁이 발생한다. 따라서 본고에서는 용선계약에서 언급되는 기한부 하역조건 또는 정박기간의 조건을 영국법의 판례로 살펴보고 그에 따른 법적의미와 해석기준을 제시하여, 국제무역과 해운기업의 실무에 도움이 되고자 한다.

To examine the effects of an educational program with a purpose of reducing symptoms and ailments of women's premenstrual syndrome on the basis of the Self-care theory of Orem, a stimulation was carried out by using pre-and post-design of non-equity control group after choosing both an experimental group of 62 persons and a control group of 62 persons among 497 industrial women. This study was conducted from June 20, 1996 to September 30, 1996. Meantime, an education was provided for the experimental group of 62 persons for 8 weeks but no education for the control group of 62 persons. Study matters are general and obstetric characteristics, knowledge and self-care behavior and premenstrual syndrome from questionnaires with 497 industrial women, pre and post questionnaires with the control group of 62 persons and the questionnaires collected before and after providing an education for the experimental group of 62 persons, these matters were used as research data for this study and analyzed by means of the SAS program. As a result, it was shown that the scores of 497 industrial women's knowledge by age were the highest 26.36 for 20 to 29 year old women, then 25.58 for 30 to 39 year old women and 25.74 for less 19 year old women. The performance scores of their self-care behavior by age were the highest 39.17 for 30 to 39 year old women, 35.72 for 20 to 29 year old women and 32.85 for less 19 year old women, which means that the older the women are, the higher the performance degree is(p<0.01). And the scores of their premenstrual syndrome by age were 2.80 for less 19 year old women, 2.18 for 20 to 29 year old women and 2.00 for 30 to 39 year old women. Women in their teens and twenties showed more serious symptoms and ailments of premenstrual syndrome than women in their thirties(p<0.01). For the experimental group of 62 persons who received the educational program, both the knowledge of premenstrual syndrome and the degree of self-care behavior were remarkably improved(p<0.01), respectively and the symptoms and ailments of premenstrual syndrome were also remarkably reduced(p<0.01), while the control group showed no change in the knowledge, self-care behavior, and symptoms and ailments of premenstrual syndrome. The above results demonstrated that educational program based on the Self-care theory of Orem is an effective intervention to reduce the symptoms and ailments of premenstrual syndrome. The effects of the study can be generalized by extending the application in which various age groups and professional and social environments are considered together with a research to evaluate the long-term effects of this educational program. Accordingly, it is expected that it can possible not only to provide help for the women by actually applying the program to practical areas for improvement of women's health but also to suggest plans to activate it as one of health education areas.

Background: The predictive value of the xeroderma pigmentosum group D (XPD) Lys751Gln polymorphism regarding clinical outcomes of patients with colorectal cancer (CRC) receiving oxaliplatin-based chemotherapy has been evaluated in numerous published studies, but the results remain inconclusive. Therefore, we performed a meta-analysis to determine the precise role of the XPD Lys751Gln polymorphism in this clinical situation and optimize individual chemotherapy. Materials and Methods: A multiple search strategy was used to identify eligible studies. Pooled odds ratios (ORs), generalized odds ratio (ORG) and their 95% confidence intervals (CIs) were used to estimate the objective response, while hazard ratios (HRs) with 95%CIs were used for progression-free survival (PFS) and overall survival (OS). Results: A total of 17 studies including 2,286 patients met the inclusion criteria. Overall, the XPD 751Gln allele was associated with a non-significant reduced objective response to oxaliplatin-based chemotherapy in all patients or in the Asian and Caucasian subgroups. However, poor PFS and OS of CRC patients treated with oxaliplatin-based regimens were significantly related to the XPD 751Gln allele in the dominant model (PFS: HR=2.10, 95%CI: 1.65-2.67; OS: HR=3.18, 95%CI: 1.57-6.47). On stratified analysis by ethnicity, these relationships were more pronounced in Asians (PFS: HR=2.49, 95%CI: 1.79-3.47; OS: HR=5.25, 95%CI: 3.46-7.94) than in Caucasians (PFS: HR=1.73, 95%CI: 1.22-2.46; OS: HR=1.78, 95%CI: 1.06-2.99). Conclusions: The XPD Lys751Gln polymorphism may have prognostic value in patients with CRC undergoing oxaliplatin-based chemotherapy.

Background: Cervical cancer is a major public health problem worldwide. There have been several studies indicating that risk is associated with geographic location and that the incidence of cervical cancer has changed over time. In Thailand, incidence rates have also been found to be different in each region. Methods: Participants were women living or having lived in upper Northern Thailand and subjected to cervical screening at Maharaj Nakorn Chiang Mai Hospital between January 2010 and December 2014. Generalized additive models with Loess smooth curve fitting were applied to estimate the risk of cervical cancer. For the spatial analysis, Google Maps were employed to find the geographical locations of the participants' addresses. The Quantum Geographic Information System was used to make a map of cervical cancer risk. Two univariate smooths: x equal to the residency duration was used in the temporal analysis of residency duration, and x equal to the calendar year that participants moved to upper Northern Thailand or birth year for participants already living there, were used in the temporal analysis of the earliest year. The spatial-temporal analysis was conducted in the same way as the spatial analysis except that the data were split into overlapping calendar years. Results: In the spatial analysis, the risk of cervical cancer was shown to be highest in the Eastern sector of upper Northern Thailand (p-value <0.001). In the temporal analysis of residency duration, the risk was shown to be steadily increasing (p-value =0.008), and in the temporal analysis of the earliest year, the risk was observed to be steadily decreasing (p-value=0.016). In the spatial-temporal analysis, the risk was stably higher in Chiang Rai and Nan provinces compared to Chiang Mai province. According to the display movement over time, the odds of developing cervical cancer declined in all provinces. Conclusions: The risk of cervical cancer has decreased over time but, in some areas, there is a higher risk than in the major province of Chiang Mai. Therefore, we should promote cervical cancer screening coverage in all areas, especially where access is difficult and/or to women of lower socioeconomic status.

과학기술부고시 2003-12호 "원자로시설부지 수문 및 해양특성 조사평가 기준" 이 신규 제정되어, 원전 액체 방사성 유출물에 대한 삼차원적인 해양확산 평가 필요성이 커지고 있다. 한국수력원자력(주)와 전력연구원은 신고리, 신월성, 신울진 원 전등 다수의 신규원전 건설이 계획 또는 추진되고 있는 동해안을 대상으로 광역 및 부지별 입지특성을 반영한 해양확산 평가기술을 개발하고 있다. 동해안의 해수유동은 동해 해수순환에 의해 영향을 받기 때문에 원전 주변의 방사성 물질의 해양확산을 보다 정확히 평가하기 위해서는 동해 해수순환에 대한 이해가 선행되어야한다. 따라서 본 연구에서는 일본 큐슈대학교 응용역학연구소에서 개발한 RIAMOM 모델을 근간으로 동해 해수순환 모델링을 수행하였다. 모델 영역은 $126.5^{\circ}E{\~}142.5^{\circ}E$ $33^{\circ}N{\~}52^{\circ}N$, 수직층은 20개로 나누었다. 이 모델은 JODC, KNFRDI, 그리고 ECMWF로 부터 구하였다. 모델링 결과, 동해 해수순환을 비교적 잘 모의하고 있는 것으로 나타났다. 향후 모델링 결과를 정량적으로 평가하기 위해 인공위성 추적 부이를 이용하여 확산 검증 실험을 실시할 예정이다.

이 연구의 목적은 대화행위 개념을 이용하여 독일어 일정협의 대화에서 나타나는 대화의 일반적인 흐름을 밝히는 데에 있다. 이 연구의 기본가정은 대화행위 개념의 도입이 자동번역시스템의 성능향상에 기여한다는 것이다. 그 이유는 통사적인 분석이나 의미적인 분석이 해결하지 못하는 문제들을, 문맥지식을 활용하여 해결하는 데에 있어 대화행위개념이 매우 유용하기 때문이다. 이 대화행위 개념의 하위분류작업은 독일에서 수행되고 있는 VERBMOBIL 프로젝트에서 이루어진 것이다. 본 연구에서는 전문가들에 의해 전사된 실제 대화 자료들을 대화행위의 개념을 활용하여 분석하고, 하나의 대화차례 안에서 발생하는 대화행위들의 연쇄와 각각의 대화차례 사이에서 발생하는 대화행위 연쇄를 조사했다. 여기서 분석대상으로 삼은 전사자료가 다른 연구에서 제시된 전사 자료와는 다소 차이를 보였기 때문에, 본 연구에서는 연쇄 개념을 대화차례사이에 뿐만 아니라 하나의 대화차례 내부까지 적용시켰다. 그리고 대화행위들간의 연쇄관계를 조사함으로써‘일정협의 대화’의 대화 흐름 도를 도출하였다. 이 대화 흐름 도는 통계분석 절차를 통해 가장 빈도수가 높게나온 대화행위 연쇄들을 토대로 만들어진 모형이기 때문에, 일상적인‘일정협의 대화’에 대한 대표성을 갖는다고 볼 수 있다.

본 논문에서는, 차수에 따라 체계적으로 변화하는 고차원펄스의 스펙트럼 특성을 이용하여 극초단 레이저펄스의 전송특성을 분석하였다. 부분응답시스템의 수정된 모델로부터 얻어지는 고차원펄스는 그 차수의 증가에 따라 FWHM폭이 현저히 감소하여 분석하고자 하는 극초단펄스의 형태에 근접하며, 그 스펙트럼과 전송대역폭도 차수에 따라 일률적으로 유도되므로 기존의 Gaussian 펄스나 Sech 펄스에 의한 근사화에 비하여 광범위하고 정확한 전송특성을 분석하는데 매우 유용함을 밝혔다. 우리는 부분응답시스템의 일반적 모델을 순환형으로 수정함으로써 정형화된 임의의 고차원펄스 형태를 얻어낼 수 있는 새로운 모델을 설계하였으며, 이를 이용하여 다양한 형태와 FWHM폭을 갖는 극초단 레이저펄스의 전송특성을 분석하는 새로운 방법을 제안하였다. 또한, 제안된 방법을 사용하여, 설정 펄스폭을 $\tau$=1(ps)으로 설정, 고차원펄스의 차수 n=1-100에서 얻어지는 FWHM 1(ps)-150(fs)의 극초단펄스의 스펙트럼을 제시하였고, 그 null-to-null 대역폭을 유도하였다. 전송특성은 레이저펄스의 보편적인 신호방식인 Unipolar 체계로 설정하여, 가능한 펄스간격에 따른 전력밀도스펙트럼을 유도하여 제시하였다. 이러한 결과는 기존의 실험결과와 일치함은 물론 레이저펄스 발생기술의 발달에 의하여 새로이 등장할 어떠한 형태와 폭을 갖는 극초단펄스에 대해서도 적용될 수 있다.

Recently rapid environmental changes due to desertification and industrialization in China make a threat to Korea, especially during Asian Dust Event (ADE). This study was aimed to compare symptoms and behaviors related to ADE between Korea and China. We conducted questionnaires on self-reported symptoms and behaviors before and during ADE. Korean and Chinese subjects were grouped into children, adults, and elderly by nation (n=791). Statistical analyses were performed by $X^2$-test, Fisher's exact test, t-test and chow's test for comparing differences between Korean and Chinese. We estimated the odds ratio for perceived symptoms during ADE by preventive behavior, using Generalized Estimation Equation (GEE). The study indicated that there were significant differences between symptoms in Korea and those in China such as cold, cough, and sore throat, especially in elderly. Preventive behaviors such as avoiding outdoor activity and wearing sunglasses were more often performed in China than Korea. However wearing mask was more often performed in Korea than China. After adjusting for age, sex, educational level, and smoking status, the odds ratio (OR) of dry cough symptom in Korea was significantly decreased by closing the windows and wearing a mask during ADE. In China, the OR of dry cough symptom was decreased by wearing a mask and avoiding outdoor activity. We found that China which had higher performance of preventive behavior showed lower prevalence of symptoms during ADE than Korea. Also preventive behaviors could affects prevalence of symptoms during ADE. This results suggest that preventive behavior. could reduce symptoms during ADE and there are needed for. more attentions to reduce a threat of ADE.
