인터넷을 이용한 사이버 거래가 빠른 속도로 증가함으로써 기업에게 있어 인터넷 쇼핑몰 구축은 더 이상 선택사항이 아닌 필수 사항이 되었다. 하지만 현재 사이버 거래 수준은 전통적 상거래 수준에 못 미칠뿐더러 거래 항목에 있어서도 매우 제한적인 것이 사실이다. 앞으로 사이버 거래는 계속적으로 증가하리라 전망되지만 제품의 특성 혹은 고객의 기호에 따라 전통적 상거래도 그 영역을 차지하며 함께 양립하여 발전할 것이다. 이에 본 연구에서는 기존의 상거래 시스템에 사이버 거래기능을 추가하는 모델을 제시한다. 먼저 지리적으로 멀리 떨어져 있는 유통망의 정보화를 위하여 인터넷 기술을 이용하고 공급체인(Supply Chain) 전체에 걸친 동기화를 위해 TOC(Theory of Constraint)의 DBR(Drum-Buffer-Rope) 스케줄링을 응용한다. 모든 생산 및 유통의 흐름 속도가 최종 분배 센타에 접수되는 고객의 요구에 따라 이루어지게 함으로써 공급체인 전체에 걸친 동기화를 이룰 수 있고 지속적인 버퍼 관리를 통하여서 재고의 절감은 물론 미출고의 발생도 최소화할 수 있다. 만약 분배 센타에 재고부족 현상이 일어날 경우에는 공급체인 상의 능력제약자원(Capacity Constraint Resource . CCR)을 찾아 개선 활동을 수행하며 공급체인의 흐름 속도를 능력제약자원에 맞추어 조절한다. 분배 센타에서 대리점 혹은 사이버 고객으로의 배송은 부분적 분할납품 Partial Transshipment : PT) 전략을 적용한다. 즉 각 분배 센타가 관리하는 수요지 중 인접한 지역을 부분적 분할납품 전략 적용 수요지로 선택하고 사이버 거래를 통해 생성된 물류가 부분적 분할납품 전략 적용 수요지에 분배되게 함으로써 각 분배 센타의 재고 완충역할을 수행하게 한다. 이에 따라 안전 재고 및 역 배송을 최소화 할 수 있을 뿐 아니라 미 출고로 인한 손실을 최소화하며 고객의 서비스를 일정하게 유지시킬 수 있을 것으로 기대된다.

GPS(Global Positioning System)is a satellite-based navigation system that we can survey where we are, anywhere and anytime. In this paper, delay-lock loop of the receiver which detects the navigation data is theoretically analyzed, and designed using the digital logic circuit. Also logic operations for the synchronization are analyzed. The designed system consists of the correlator which correlates the received C/A code and the generated C/A code in the receiver, the C/A code generator which generates C/A code of selected satellite, and the direct digital clock syntheizer which generates the clock of the C/A code generator to control the C/A code phase and clock rate. From the analyses results of the proposed digital delay-lock loop system, the system has the detection propertied over 90% when its input signal power is above-113.98dB. The influence of input signal variation of digital delay loop, which is the input of A/D converter, is investigated and the performance is analyzed with the variation of threshold level via the computer simulation. The logic simulation results show that the designed system detects precisely the GPS navigation data.

The purpose of this study was to recognize the level of acknowledgement of the psychological support services for actors, the significance of psychological factors during performance, experience, the actual situation, and the solution to psychological matters, contribution of the psychological factors to performance and competency to control, and demand for counseling and consider ways to promote these in the future. A questionnaire was developed by specialists and analyzed both through quantitative and qualitative methods. As a result, it turned out that actors perceive the effect of psychological support services such as counseling and psychological skill positively. Even though actors understand the importance of psychological factors in practice and performance in the stage, participation in education or information regarding psychological support services were rarely realized. Also, psychological factors such as confidence, concentration, sense of achievement, motivation, positive attitude and thought, setting a goal for performance, mind control, image training, and self-consciousness are regarded as highly contributing to the performance, but actors cannot control these psychological aspects effectively in fact. Actors were very positive in participating in psychological support services and hoped to have professional counseling and psychological skill services. This study can be used as a standard in supporting the field of play practically in terms of planning for psychological support services for actors, development of psychological support program, and enforcement of education on the spot.

This study was undertaken to identify factors affecting the mental health of nursing students, including career motivation, sense of humor, and problem-solving ability, and to provide data for improving mental health of nursing students. This research enrolled 235 nursing students in B and Y cities. Data were collected from October 22 to October 31, 2018, and analyzed by applying t-test, ANOVA, Pearson's correlation coefficient, and multiple regression, using the SPSS/WIN 22.0. The average score for mental health was determined to be 2.19±0.77. Ed. Negative correlation was obtained between mental health and career motivation (r=-0.443, p<0.001), mental health and sense of humor (r=0.400, p<0.001), and mental health and problem-solving ability (r=0.465, p<0.001). Regression analysis showed that 33.4% variance in the mental health of nursing students is affected by gender (β=-0.121, p=0.033), pocket money (β=0.123, p=0.028), peer relation (β=0.165, p=0.004), sense of humor (β=-0.168, p=0.012), and problem-solving ability (β=-0.186, p=0.006). Data from this study indicates a necessity to repeat the study for identifying general characteristics and psychological factors that control an individual, and technical factors that can be acquired through learning. Taken together, we believe that the factors included and indicated in this study influence the mental health of nursing students.
