This study was attempted to improve the mental and psychological health of nursing students through the intervention of positive psychological programs using complementary alternative therapy. This study applied a Non-equivalent control group pre-test and post-test design to verify the effects of negative emotions, career decision making self-efficacy, self-compassion, and flourish in nursing students. The experimental group is the students who received the positive psychology program using complementary and alternative therapy, and the control group is the students who did not receive the program. The collected data were analyzed using the SPSS Version 21.0 program. The experimental group showed higher career decision making self-efficacy, self-compassion, and flourish scores and lower negative emotion scores than the control group that did not participate in the education. After applying the positive psychology program using complementary and alternative therapy, it contributed to the expansion of the nursing intervention area using complementary and alternative therapy by reporting positive research effects on career decision making self-efficacy, self-compassion, and flourish.

We consider statistical methods for nonresponse problem in social and economic sample surveys. To create a complete data set, which does not include item nonresponse data, imputation methods are generally used. In this paper, we introduce some imputation methods and compare them with one another. Also, we consider some problems, which occur when an imputed data set is treated as a response data set. Due to the imputed values, the true variance of the estimator after imputation is increased by the imputation variance. However, since usual naive variance estimator constructed from the imputed data set does not estimate the imputation variance, the true variance of the estimator after imputation tends to be underestimated. Theoretical reason is investigated and serious results are explained through a simulation study. Finally, some adjusted variance estimation methods to compensate for underestimation are presented and discussed.

This study was performed to determine the effects of hamburger patties added sea tangle powder and/or cooked rice on postprandial plasma glucose and lipid levels. Four patties were prepared; one control patty (C) and three experimental patties (L, LI, and LII). L was the patty with sea tangle powder substituted for 2.5% of meat while LI and LII were the patties with cooked rice containing sea tangle powder substituted for 25% and 50% of meat, respectively. Ten healthy women voluntarily participated in the clinical test. Plasma glucose and lipid levels were measured at 0, 30, 60, 90, 120, 180, and 240 minutes after consuming each of the four patties. After consuming L, LI, or LII, changes in area under curve (${\Delta}$-AUCs) of plasma glucose, triglyceride, total cholesterol, and LDL-cholesterol were significantly lower than that after consuming C. However, ${\Delta}$-AUCs of plasma HDL-cholesterol after consuming L, LI, or LII were significantly higher than that after consuming C. These results indicate that the patty substituted with 2.5% sea tangle powder for meat might improve blood glucose concentration, whereas patties substituted with cooked rice containing 25% or 50% sea tangle powder might ameliorate plasma lipid profiles.

In this study, the complementary or crowding-out effects of public R&D subsidy on private R&D investment in the cleaner production were analysed between the effects and the major determinants (company size, R&D investment intensity, ratio of government investment, R&D manpower intensity). Among 207 firms' projects, the number of the complementary effect was 95 (45.9%) while that of crowding-out effect was 38 (18.4%). Resulting from logistic regression, the higher the R&D investment of sponsored companies is, the more complementary effect they show, responding to public R&D subsidy, and increase own R&D investment. The other determinants, however, showed no significant effects on firms' R&D investment. To heighten the effect of public cleaner production R&D, it is need to increase the priority of R&D investment intensity among the determinants. And to increase the performance of governmental R&D investment, further studies for the individual public R&D programs are necessary.

We consider the estimators for the parameters of the exponential model with limited replacements under the type I censoring scheme. Also, we propose the desirable number of replacements to provide the similar effects in terms of the mean square errors.

망 복구에 있어서 주요한 과제는 복구의 대상으로 하고 있는 작업 경로(working path)에 대한 복구경로(restoration path) 흑은 대체 경로(backup path)를 설정하는 것이다. 대체 경로를 설정할 때 작업경로의 대역을 보장할 수 있는 대체 경로를 설정해야 한다. 따라서 이 과제는 대역의 보장을 고려하여 경로를 설정하는 QoS 라우팅의 해결책이 요구된다. 본 논문에서는 동일 링크의 작업 경로가 아닐 경우 대체 경로의 대역을 공유함으로써 최대한 대역의 소비를 피하면서, 작업 경로의 대역을 보장하는 대체 경로를 설정하는 disjoint 경로를 계산하는 알고리즘을 제시하고 시뮬레이션을 통해서 대체 경로로 인한 대역의 소비(bandwidth consumption) 효과를 분석하였다.

A certain group of phytochemicals such as isoflavone have been proven to act as a phytoestrogen. After thorough the study of different bibliographic herbs excluding soybeans, dates, pomegranates, and other publicized plants, three different edible herbs by Korean Food Regulation were extracted for the animal study on the effect of estrogen replacement. The herbal extract(FGF271) has been orally administered into 51 weeks old partial ovariectomized rats for 5 weeks with the different dosages of 100 and 1,000 mg/kg, respectively. It was observed that 1) serum estrogen level was increased in both 100 and 1,000 mg/kg group, 2) the distension of uterus was made dose dependently and significantly different in 1,000 mg/kg group (p.0.05) from control in the gross findings, 3) the weight of uterus was increased in 1,000 mg/kg group, and 4) the action on reproductive tissues was clear in the microscopic findings in terms of hyperplasia of endometrial epithelial cell, cystic change of submucosa, dilatation of uterus (significantly increased in 1,000 kg/mg), and follicular cystic changes in ovary. As a result, FGF271 seemed to act as a phytoestrogen by inducing the change in ovary and uterus and by increasing the serum estrogen concentration.

The US and EU have imposed energy sanctions on the Russian oil and gas sector in response to the Ukraine crisis. One of the key measures is to cut oil and gas imports from Russia. The US and EU are both the senders of sanctions against Russia. However, there is a fundamental difference between them. While the US is the net oil and gas exporter, most EU member states are heavily dependent on Russian oil and gas. If the US and other major oil and gas exporting countries can replace Russia in the EU energy market, the effectiveness of energy sanctions against Russia can be guaranteed. Our result shows that it is difficult for the major oil and gas exporters to fully replace Russia in the short run because of the lack of additional production capacity and infrastructure. We conclude that the US and EU's energy sanctions against Russia can not guarantee its effectiveness. We argue that other measures, such as diplomacy, should be taken to settle the conflicts in Ukraine.

The purpose of this study was to identify the perception of alternative medicine and factors affecting the intention to use for nurses and caregiver. In order to achieve the purpose of the study, this study was conducted to examine the awareness of alternative medicine, use experience, and intention to use for 400 workers in hospitals and nursing homes. The results of the analysis are summarized as follows. Recognition of alternative medicine effected on reliability of alternative medicine, awareness and use experience. In addition, experience with alternative medicine has a negative impact on the intention to use alternative medicine. In conclusion, this study suggested that the development of alternative medicine requires efforts to improve the therapeutic effect of alternative medicine.
