In the zoom lens of digital still cameras with the variation of the image plane generated by various symmetric error factors such as curvature, thickness and refractive index error of each lens surface about the optic axis, we induce a theoretical condition to fix constantly the image plane by translating the compensator group of the zoom lens by using the Gaussian bracket. We confirm the validity of this condition by using three examples of general zoom lens types with 3, 4, and 5 groups, respectively. When these error factors are randomly changed within the range of tolerance according to the Monte Carlo method, we verify that the distributions of the degree of moving of the compensator are normal distributions at three zoom lens types. From capability analysis using these results, we theoretically propose the method estimating the standard deviation, that is, sigma-level, as a function of the maximum movement of the compensator.

This study purports to investigate the determinants of intent to leave of dental hygienists working at dental clinics. The sample used in this study consisted of 356 dental hygienists selected from nationwide Korea. The independent variables contain three groups of determinants: 6 structural variables, 2 psychological variables and one environmental variable. Job satisfaction and organizational commitment were included in the model as intervening variables. Data were collected with self-administered questionnaires and analyzed using path analysis. The results of the path analysis indicate that the following variables have significant total effects on the intent to leave of dental hygienists: organizational commitment, supervisory support, job satisfaction, alternative job opportunity, positive affectivity, role conflict and job autonomy. The results imply that the administrators of dental clinics should make an effort to motivate dental hygienists by redesigning their work process, to provide them with more autonomy in doing their work, and to develop their job knowledge and skills through continuous training and education.

This paper describes a charge sharing capacitive-sensing circuit technique that improves the quality of images captured with fingerprint sensor LSIs. When the finger is dry, the electrical resistance of a finger surface is high. It leads to poor image quality. To capture clear images even when the finger is dry, the modified capacitive detection circuit improves the image quality using an enhancement plate at the finger surface and a voltage control circuit. The test circuit is analyzed on $0.35{\mu}m$ CMOS process.

This study analyzed the factors affecting organizational adaptation among the members of SMEs. Until now, research on organizational adaptation has been mainly conducted in large corporations or public institutions. Very little research has been conducted on SME members. Factors affecting the organizational adaptation of employees were set by individual factors and job environment factors. In the individual factors, the sub-variables were set as self-efficacy, optimism, and resilience, and in the job environment factors, organizational fairness and organizational culture. The sample data were surveyed using a survey method such as visit, telephone call, e-mail and fax. 98 data were used for the analysis. Statistical analysis was performed using regression analysis. As a result, self-efficacy, optimism, and resilience of individual factors were analyzed as positive variables for organizational adaptation of employees, and organizational fairness in the job environment was analyzed as variables that did not positively affect organizational adaptation of employees. However, the organizational culture of the job environment was analyzed as a variable that positively affects organizational adaptation of employees. These results showed that the fair application of wage level, workload, compensation, and opinion reflection did not affect the organizational adaptation of employees. On the other hand, in the preceding studies, organizational adaptability was conducted mainly in large corporations, but this study was able to suggest practical implications in analyzing organizational adaptability among SME members.

The bonding process should be achieved in vacuum environment to avoid air bubble. In this study, we studied about pressure uniformity that became an issue in thermo compression bonding usually. Uniform press is realized by the method that use air spring and metal form spring. The concept of uniform press using air spring is removed except pressing direction in the press processing so angle between the vector of pressure surface and the pressure axis is parallel automatically. Air spring compensate the errors of machining and assembly. Metal form compensate the thermal deformation and flatness error.

기업의 성과관리와 성과평가 분야에서 성과지표의 분류는 조직의 내부 구성관계 즉, 수직적 (vertical) 구조(전사-본부-팀)와 수평적 (horizontal) 구조(본부와 본부 혹은 팀과 팀간)의 공유에 따라 구분될 수 있으나 기존 연구(Lipe & Salterio 2000, Dilla & Stcinbart 2005)에서는 공통지표와 고유지표라고 하는 수평적인 측면만이 고려되고 수직적인 측면은 고려되지 않았다는 한계가 있다. 조직의 성과가 향상되기 위해서는 하부조직이 전사 전략에 집중 할 필요가 있으며 이를 위하여 전사의 비전을 위한 전략목표달성에 기여한 정도를 측정하여 보상과 연계하는 것은 성과관리제도가 추구하는 기본 방향이며 도입목적이기도 하다. 그런데 선행 연구에서 밝혀지지 않은 조직구성 관계의 수직적 측면에서 전사지표의 정렬(Alignment)을 통한 공유와 할당(Cascading)된 지표의 가중치를 고려해 볼 때 고유지표는 재 정의하여 세분화 할 필요가 있다는 점이다. 즉, 특정 부서의 지표 중에는 전사 혹은 상위부서에 반영되어 공유하고 있는 고유지표(이하 공유지표)와 전사 혹은 상위부서에는 반영되지 않고 해당 부서만 독점하고 있는 순수한 고유지표(이하 고유지표$^{1}$)로 구분되어야 하며 공유지표와 고유지표의 분류에 따라 가중치 설정이 달라져야 한다는 주장이 그것이다. 따라서 본 연구의 목적은 조직이 성과를 공정하게 평가하고 하부조직이 전사전략에 집중하도록 하기 위해 공통지표와 고유지표를 사용하고 있는데(Dilla & Steinbart 2005), 고유지표를 공유지표와 고유지표로 재 정의하고 분류하여 관리 할 필요가 있다는 점과 각각의 지표 분류에 따라 가중치 설정에 차이가 있는지에 대한 유의성을 검증해 보고자 한다.

The modern pentathlon is an exercise in which people and people compete, as well as exercise without equipment, exercise using equipment, and exercise with animals, and it is an exercise that includes static and dynamic exercise. The ethical issues of modern pentathlon athletes are also related to the poor environment and economic reasons, and the athlete's ethical awareness, attitude, and spirit have a great influence on the athlete's mental environment. In this study, the direction of improvement of ethical problems, which are different as important issues in modern sports, was examined, and qualitative research methods were applied to explore the sports spirit and ethics of the modern pentathlon. Correct sports should not deviate from the intended purpose of the exercise or cause or force the athlete to suffer physical or mental pain. In sports, compensatoryism can be a direct cause of improved performance or record-breaking, but sometimes it can also cause distorted athletes. Air doping has ethical issues that can cause controversy over the health or fairness of athletes, mental and physical damage to athletes, and harm. Responsibilities and ethical issues of athletes who take prohibited substances or leaders or supervisors who neglect or encourage them should be treated as very important matters. In the sports field, the reward system that is subordinate to the athlete's or leader's performance is related to the athlete's or leader's livelihood. For a fair and just game progression, it is necessary to break away from the development of athletes who are only focused on performance. The problem of Unethical issues must be overcome by emphasizing the restoration of ethics that are reasonably recognized in ideology and logic.
