In this paper, we propose the smart belt system for preventing loss of items using Beacon. The proposed system monitors the distances of the registered items via the belt that is always worn. The belt determines the loss of the items by measuring the relative distance via RSSI (Received Signal Strength Indicator) value of the signals received from the BLE (Bluetoothl Low Energy) sensor, which is attached on the items such as bags and wallets. If the registered item is determined to be lost, the belt rings to remind the user of the loss. The missing status could be known to users through the smartphone application connected to the belt. The smartphone application communicates with the belt using Beacon, and provides users with a quick and easy way to check the status of their items.

Recently with the development of IT technology, the medical technology have been developed in various ways. Among them, WBAN can check the state of the patient in real time. However, the data generated by these techniques have a problem that they have heterogeneous properties depending on the type of sensors and devices. In this paper, we proposed a method using meta repository as a way to provide the sensing data of WBAN for the health care system by integrating along the HL7 standard item.

Purpose: The Edinbergh Postnatal Depression Scale (EPDS) has seen widespread use in epidemiological and clinical studies. The objective of this research was to translate and to test the reliability and validity of the 10-item EDPS in Korea. Methods: Subjects were 145 women who were 6 to 10 weeks post delivery. To test reliability, the internal consistency was assessed by Cronbach's alpha coefficient. Validity testing was performed using convergent validity by Pearson's correlation. Data was gathered at 3 hospitals during Oct. 2005 after obtaining an informed consent. Result: The mean age of the subjects was 29.9 years. and the mean parity was 1.46 times. The mean EPDS score was 18.4. Reliability analysis showed a satisfactory result (Cronbach's alpha coefficient=.84). There were significant positive correlations between EPDS and Mills postnatal depression and anxiety check list scores as expected(r=.69, p<.001) and thus supported convergent validity. Conclusion: The study findings showed that the Korean version of the EPDS-10 is a reliable and valid instrument that can be used for measuring postnatal depression in Korea.

Purpose: The purpose of this study was to examine the level of knowledge and learning needs of patients with a permanent pacemaker implantation. Methods: The participants were 86 patients with a permanent pacemaker implantation. Data were collected during April and May 2002 using a questionnaire survey on knowledge and level of learning need. The collected data were analyzed using the SAS program. Results: 1. The average knowledge score was 13.21. The knowledge level was significantly higher in participants under 50 years of age and for those with higher levels of education. The items with the highest knowledge score was 'permanent pacemaker needs regular check ups' and the lowest, 'a bath can be taken 1 month after stitches are removed'. 2. The total average score for learning needs was 60.78 and the mean item score was 3.04 as measured on a 4-point Likert scale. The item showing the highest learning need was 'electrical fields can affect the pacemaker's function and the lowest learning need was for sexual activity after permanent pacemaker implantation'. Conclusion: According to the above findings, it can be concluded that an intensive nursing education program should be developed for patients with a permanent pacemaker especially for those patients over 50 years of age and those with lower levels of education.

연관성 규칙은 방대한 양의 데이터베이스 속에 있는 각 항목들 간의 관련성을 수치화함으로써 두개 이상의 항목간의 관련성을 나타내는 기법으로 데이터 마이닝 분야에서 가장 많이 활용되고 있다. 의미 있는 연관성 규칙을 탐색하기 위한 가장 기본적인 평가기준에는 지지도, 신뢰도, 향상도 등이 있으며, 이들을 이용하여 연관성 규칙을 생성하게 된다. 이 때 사용되는 향상도는 그 값의 범위가 지지도나 신뢰도와는 다르므로 지지도나 신뢰도의 범위를 동일하도록 하기 위해 표준화할 필요가 있으며, 지지도와 신뢰도도 하나의 후항변수에 대해 여러 개의 전항변수들이 있는 경우 이들 중 어느 것이 후항변수와 가장 연관성이 있는지를 객관적으로 비교하기 위해서도 표준화가 필요하다. 본 논문에서는 각 항목집합의 주변 발생확률을 고려하여 객관적이고도 정확한 연관성 정도를 파악하기 위해 연관성 평가기준을 표준화하는 방안에 대해 연구하고자 한다. 또한 흥미도 측도의 세 가지 조건의 충족 여부를 점검해 본 후, 구체적인 예제를 통하여 기존의 연관성 평가기준과 표준화된 연관성 평가기준을 비교 분석하고자 한다.

연관성 규칙 마이닝은 지지도, 신뢰도, 향상도 등의 흥미도 측도를 기반으로 하여 대용량 데이터베이스를 구성하고 있는 항목들 간의 관련성을 찾아내는 기법이다. 이 기법은 기업의 의사결정 문제, 유통업에서의 교차판매, 고객관리 등 현업에서 많이 활용되고는 있으나, 이러한 기본적인 연관성 평가기준만으로는 두 항목 간의 인과관계를 설명할 수 없다. 본 논문에서는 이러한 문제를 해결하기 위해 인과적 연관성 규칙을 제안하는 동시에, 고려하는 평가 기준들이 흥미도 측도의 조건을 충족하는지의 여부를 점검하였다. 본 논문에서 제안한 인과적 향상도는 세 가지 조건 모두를 만족하는 것으로 입증되었다. 인과적 지지도와 인과적 신뢰도는 동시 발생 확률의 값에 따라 단조 증가하는 조건과 각 항목의 주변 확률의 값에 따라 단조 감소하는 조건은 만족하였다. 반면에 두 항목이 독립이면 연관성 평가기준의 값이 1이 되는 조건에 대해서는 기존의 지지도와 신뢰도와 같이 이 조건이 충족되지 않았다. 또한 예제를 통해 기존의 연관성 평가 기준과 인과적 연관성 평가 기준을 비교해 본 결과, 기존의 평가측도인 지지도와 신뢰도를 기준으로 연관성 규칙 생성 여부를 판단했을 때 탈락되는 규칙도 인과적 평가 기준인 인과적 지지도와 인과적 신뢰도를 이용하여 판단하게 되면 연관성 규칙으로 채택할 수 있다는 사실을 발견하였다.

The present study is designed to analyze reliability and validity of the instruments used to measure job stress of radiological technologists mainly by means of the questionnaires from 'Korean edition of NIOSH check list'. The subjects of this study are 890 radiological technologists active at 44 general hospitals in 16 provinces and cities across the country. The item-total reliability revealed that 10 factors in 6 are the major causes of stress in job life of radiological technologists. The measuring instrument proved to be valid with reliability coefficient of internal consistency by factors being more than 0.7. The factors found to be applicable herewith include limit and authority of job (0.73), cohesion within departments (0.86), resources control (0.81), mental requirements (0.85), job load (0.82), and job stability (0.72). When job autonomy item of causes are modified for proper use to radiological technologists, the measuring instruments are expected to show high reliability. It seems, however, necessary to develop a measuring instrument to analyze and use the validity of related measuring instruments since the reliability here was rated low, with statistical coefficients lower than 0.7 in such factors as job management (0.57), conflicts within departments (-1.13), sense of responsibility for patients (0.66) and usage of education (0.26). As this study was intended to examine reliability and validity of the concepts related to measurement of job stress on the part of radiological technologists, it nay not be proper to apply the results of this study to general use, but is advised to utilize them as basis for developing instruments to verify reliability and validity by comparing with and analyzing other measuring instruments.

Purpose: The purpose of this study was to examine comparison in the frequency and importance of nurse's job in new graduate nurses working in musculoskeletal ward. Method: A descriptive design was used with convenience sampling of 72 new graduate nurses working in musculoskeletal ward of the 2 hospitals with over 500 beds. Data were collected using a structured questionnaire. Results: 1) The total score for frequency of nurse's job was $2.57{\pm}.41$ and the total score for importance of nurse's job was $3.00{\pm}.37$. 2) The most frequent category was to manage for a medication and the most frequent item was to administer a medication in the order. 3) The most important category was to control of tissue perfusion and the most important item was to keep the aseptic techniques. 4) The frequencies among the work places were different significantly in 3 categories. 5) The importances among the work places were different significantly in 2 categories. Conclusion: New graduate nurses perceived the importance than the frequency of nurse's job. Also check or analysis the vital sign and nurses job associated with medication were higher score. Therefore, further research is needed to develop the educational strategies to strengthen not only theory also practice.
