Purpose : Neonatal hydronephrosis is diagnosed with an incidence of 4.5-7% of pregnancies. Recently, early detection of neonatal hydroneprosis with antenatal ultrasonography has be-come possible. But consensus about its management has not been reached, especially concerning surgical intervention. The purpose of this study is to analyze the natural course of neonatal hydronephrosis and to determine the guideline of surgical intervention and follow up study. Methods : Sixty nine hydronephrotic kidneys were confirmed from April 2001 to April 2005. All cases were rechecked by ultrasonography once at least and had a minimum follow-up of 6 months. We classified the patients into 4 groups according to the anterior posterior pelvic diameter(APPD) on perinatal ultrasonography. Ultrasonography to measure the APPD diameter and Society for Fetal Urology(SFU) grade, $^{99m}Tc-MAG3$ scan were done to a set protocol. Pyeloplasty was peformed according to the protocol. Results : Pyeloplasty was not needed in most cases where the APPD was below 10 mm and where the SFU grade were less than grade 3. Many cases with APPD 10 mm above or SFU grade III above had undergone pyeloplasty. We found a correlation between obstruction grade on MAG3 scan and whether surgery was performed or not. Conclusion : If APPD is above 10 mm, SFU grade is above grade 3 or urinary tract obstruction is suspected by MAG3 scan, pyeloplasty must be considered. In cases where APPD is below 10mm and SFU grade is less than grade 3, we can observe the natural course of neonatal hydronephrosis with consecutive follow-up.

The purpose of this paper is to examine the major elements of Arbitration Clause in international investment contracts and to help the investor, especially foreign investors, considering these elements when they draft the contracts. First of all, to describe the extent of the arbitrable issues broadly is very important by using the phrase such as "disputes in connection with". Furthermore in order to be enforceable, the issues must be a subject-matter to be submitted to arbitration in accordance with the laws of the place of arbitration and the law application to the merits of the disputes (N.Y. Convention, Art. II). Second, the appointment of the arbitrators usually shall be based on the principle of freedom of contract. If the parties do not agree on the appointment, it is decided in accordance with the arbitration rules of the institution by the tribunal. Third, the procedural rules of the arbitration are the arbitration rules of the arbitration institution in case of institution arbitration, unless otherwise agreed. Forth, what is the most importance element of Arbitration Clause is the place of arbitration. In this case, also the principle of freedom of contract has priority. Unless otherwise agreed, Washington is the place of arbitration in case of ICSID Arbitration, but in case of ICC Arbitration, neutral third country may be the place of arbitration. However in case of ad hoc arbitration, both parties should indicate the place. If not, the whole arbitration may be paralysed by an uncooperative party. Besides the major elements, I examined the relation between the arbitration clause and award enforcement in terms of sovereign immunity. The enforcement of awards in the field of state contracts many encounter the problem of the sovereign immunity, which means that the State itself or the State enterprise is the contract partner. To avoid the this problems, it is advisable for the parties insert the clause such as ICSID Model Clause XIX.

During pregnancy, the woman experiences physical and psycho-social changes. Such changes and other factors may become stress for the pregnant woman, making it difficult to maintain healthy and happy pregnant period. In this study, we identify factors for the stress, marital intimacy, family support, and fatigue, in order to provide the foundation for developing intervention programs and improve the quality of nursing. The subjects of there search were 185 pregnant women. Stress had a negative correlation with marital intimacy and family support, and positive correlation with fatigue. Family support, fatigue, adjustment to change due to pregnant, and breastfeeding experience were the influencing factors on the stress of pregnant women. A stress management program for pregnant women needs to be designed to help them with their physical and psychological adjustments. The program will be more effective when accompanied by the family support.

This study comprised descriptive research into nurses' anger, job stress and social support, and the impact thereof on interpersonal caring behaviors. This study focused on the anger and interpersonal caring behaviors of nurses. From December $1^{st}$ to $31^{st}$ 2014, the data of 174 working at university hospitals in four cities were collected. This study focused on the anger and interpersonal caring behaviors of nurses. Repeated anger rumination reduced interpersonal caring behaviors. The influence of anger-in and anger-control on interpersonal caring behaviors was confirmed. Although the stress score of job demand was too high, an autonomous nursing environment, material support and expansion of the educational period are required to enhance interpersonal caring behaviors. Thus, this study investigated the elements of interpersonal caring behavior necessary for nursing care and suggests the necessity on convergence study of addressing feelings of anger as an emotion management intervention.

The purpose of this study was to examine the predictive relationships between the predictors and self-esteem among hemodialysis(HD) patients. Predictive correlational design, participants 154 HD patients in the Seoul. SPSS for Window 22.0 used to perform descriptive statistics, Pearson's Correlation Coefficient and Stepwise Regression analysis. The strongest predictor was uncertainty (${\beta}=-.33$, p<.001), economy (${\beta}=.18$, p<.05), occupation (${\beta}=.17$, p<.05) and health status (${\beta}=.16$, p<.05) were followed. A total explained variance was 30.0% of self-esteem (Adjust $R^2=.30$). Managing or preventing uncertainty, providing vocational education in consideration of the dialysis environment, providing employment, increasing economic level, and maintaining good health status are factors that enhance self-esteem. Conducted to investigate the self-esteem of HD patients considering the machine-dependent characteristics, future, provide the data of the study to improve the self-esteem of HD patients. Also, nursing intervention should be developed based on the findings.

A laboratory investigation is conducted to characterize and quantify fatigue lives of continuously reinforced concrete pavements (CRCP) with initial design parameters. Eight specimens scaled were made based on results of finite-element analyses and stress-strain curve comparisons. Static tests were firstly performed to obtain magnitudes of static failure loads and to predict crack patterns before fatigue tests. The fatigue lives measured in the study were compared based on each initial design parameter. The comparison indicates that the fatigue lives of CRCP specimens with initial cracks increases with increasing the initial crack spacing, and CRCP specimens with reinforcements at top of the concrete slab have more fatigue lives than those with reinforcements at midheight of the concrete slab. In addition, the fatigue lives were significantly affected by soil conditions under the CRCP specimens. The results obtained in the study can be used for maintenance and retrofit of the continuously reinforced concrete pavements.
