Purpose: The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic. Methods: Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory. Results: The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples. Conclusion: When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

본 논문에서는 OFDM 기반 이동통신시스템에서 idle mode 단말의 전력 소모를 감소시키기 위하여 기존의 프리앰블에 PI(Paging Indicator) 정보를 추가하여 전송하는 기법을 제안한다. L1/L2 제어채널을 사용하여 PI를 전송하는 기법과 비교하여, 프리앰블을 이용하여 PI를 전송하는 기법은 PI 전송을 위한 추가의 overhead가 필요하지 않을 뿐만 아니라 PI 검출을 위한 복잡도도 감소시킬 수 있다. 본 논문에서는 OFDM 기반 이동통신시스템, 특히 mobile WiMAX 시스템에 적합한 동기화 기법과 PI 검출기법에 대하여 기술한다. 모의실험을 통하여 mobile WiMAX 시스템에서 동기화 성능과 셀 탐색 성능을 크게 열화시키지 않으면서 프리앰블(또는 common synch symbol)을 사용하여 PI를 전송할 수 있음을 확인한다.

This paper presents a method of the regional long-term distribution planning considering economic indicator with the assumption that energy demands proportionally increases with the economic indicators. For the practical distribution planning, it is necessary to regional load forecasting, distribution substation planning, distribution feeder planning. Accordingly, in this paper, after performing regional load forecasting considering economic indicator, it is performed distribution substation planning and distribution feeder planning in order by using this result. For accurate distribution planning, it is very important to scrutinize the correlation among the regional electric power demands, economic indicator and other characteristics because distribution planning results may vary depending on many different factors such as electric power demands, gross products, social trend and so on. In this paper, various steps microscopically and macro scopically are used for the regional long-term distribution planning in order to increase the accuracy and practical use of the results

This paper describes development of real-time condition monitoring system to observe state of a container crane in a port. To analyze the state of a crane, the strength and the direction of wind are measured with sensors along with the load resulted a crane at the moment. The measured signals are processed by especially developed conditioning board and converted into digital data. Measured data are analyzed to define the state of the crane at an indicator. For transmission of these data to the indicator, we implemented wireless sensor network based on IEEE 802.15.4 MAC(Media Access Control) protocol and Bluetooth network protocol. To extend the networking distance between the indicator and sensor nodes, the shortest path routing algorithm was applied for WSN(Wireless Sensor Network) networks. The indicator sends the state information of the crane to monitoring server through IEEE 802.11 b wireless LAN(Local Area Network). Monitoring server decides whether alarm should be issued or not. The performance of developed WSN and Bluetooth network were evaluated and analyzed in terms of communication delay and throughput.

The purpose of this study was to identify factors influencing patient satisfaction and to evaluate the utility of patient satisfaction as an outcome indicator. The study was conducted by mailed questionnaire. The subjects were 900 patients discharged from adult nursing units in a tertiary teaching hospital. On the discharge date, questionnaires were distributed by two trained research assistants. The questionnaire developed by the researchers was based on Larson(1996)'s study, and consisted of 71 items with the following components: overall satisfaction, domain-specific satisfaction(administration process, hospital facility and environment, nurses, and doctors), patients' loyalty(intention to use the health care service of the hospital in the future), recommendation to others, health benefits, and demographic characteristics. Each item was rated using a five point Likert scale ranging from '1=strongly disagree' to '5= strongly agree'. The response rate was 43%(387/900). The satisfaction level with the health care service was generally high. Perceived health status was the only significant factor influencing satisfaction level. Satisfaction with doctors contributed the most to explaining overall satisfaction. Overall satisfaction was significantly correlated with patient loyalty, recommendation, to other and perceived health benefit. It was found that the score of satisfaction was positively correlated with the score of loyalty, recommendation, and health benefit. Therefore, patient satisfaction seems to be a good outcome indicator.

Since 1984, many patients have been treated with Multiloop Edgewise Archwire (MEAW) Technique and diagnosed with ODI (Overbite Depth Indicator) and APDI (Anteroposterior Dysplasia Indicator) by the authors. 234 samples of them were selected randomly for the statistical analysis (age, sex, Angle's classification, treatment period, extraction, ODI etc.). Especially, ODI was analysed statistically and its application methods were reviewed. The results and conclusions were as follows: 1. On the 150 patients with normal overbite, the mean values of Class I, II, III malocclusion were $67.5^{\circ}$, $72.2^{\circ}$ and $59.0^{\circ}$. They were significantly different on the level of p < 0.01. 2. In normal overbite samples, ODI decreased with the increase of APDI and the correlation coefficient was -0.54. It seems that this result reflects the characteristics of AB to mandibular plane angle. 3. The regression equation was Y = - 0.57X + 114.64, where X is APDI and Y is ODI. In cases of small or large APDI, it seems to be absurd that the patient's ODI is compared with the mean ODI to differentiate diagnostically the open bite or deep bite tendency from the normal.

본 논문은 locking 상태에 따라서 루프대역폭이 변화하는 Phase Locked Loop (PLL)의 구조를 제안하였다. 제안한 PLL은 기본적인 PLL 블록과 NOR Gate, Inverter, Capacitor, 그리고 Schmitt trigger로 이루어진 Locking Status Indicator(LSI) 블록으로 구성되었다. LSI는 Loop Fille.(LF)에 공급되는 전류와 저항 값을 locking 상태에 따라 변화시켜서 unlock이 되면 넓은 루프대역폭 가지는 PLL로, lock이 되면 좁은 루프대역폭을 가지는 PLL로 동작하도록 한다. 이러한 구조의 PLL은 짧은 locking 시간과 저 잡음의 특성을 동시에 만족시킬 수 있다. 제안된 PLL은 Hynix CMOS $0.35{\mu}m$ 공정으로 Hspice 시뮬레이션 하였으며 40us의 짧은 locking 시간과 -76.1dBc 크기의 spur를 가진다.
