There have been many developments in super precision working technique and working method up to, now. But, it is very difficult to evaluate working surface accurately without the technicians experience and judgment. Surface roughness tester using stylus was used to measure surface condition generally But this method is not so desirable because of damage on test piece caused by contact between the workpiece and the stylus sensor. As a result, non-contact method was known as a good way to carry, out this process without damage. However, this is a difficult one among the various measuring methods. So we are tying to suggest a new method using texture analysis through image processing to get a surface information in worked test piece. Co-occurrence matrix using difference of gray levels between a pixel and its neighboring one was used to study behavior of surface roughness and to J acquire data for analysis. Standard specimen was adapted to verify this research. We suggest texture information method in order to evaluate surface state for the best measurement system.

The concept of a new linear motor that uses piezo-stack actuator is demonstrated. The working principle is far different from the conventional inchworm motor. This motor is based on the self-moving cell concept. The linear motor has three cells and each cell is constructed with one piezo-stack actuator and a shell structure. A cell train is constructed by connecting these cells and the cell train is fitted into a guide way with a proper interference. The cell train moves along the guide way, by activating each cell in succession. The moving motion of the motor is tested. Since this linear motor uses piezo-stack actuator with unified clamping cell, it can produce fast speed, high resolution and large push force.

정보기술의 발달에 따라 집에서 근무하는 재택근무제는 조직과 조직원 모두에게 도움이 되는 미래지향적인 근무방식으로 인식되고 있으며, 선진국을 중심으로 재택근무제에 대한 관심이 높아지고 있다. 기업에 요구되는 비용절감 압력 가중에 따라서 재택근무제가 조직 경쟁력 제고의 중요한 수단으로 고려되고 있으나, 재택근무제도에서 발생할 수 있는 조직원의 이탈 및 통제 문제에 대한 연구가 부족한 상황이다. 본 연구에서는 기존 연구에서 논의되었던 보상전략들과 조직몰입의 관계를 재택 및 내근의 상이한 근무제도 상황에서 비교하여 제시하였다. 이를 통하여, 상이한 근무제도에서 기업이 선택해야할 보상전략을 찾고자 하였다. 연구의 결과, 기업의 외재적 내재적 보상이 근로자의 지속적 몰입에 미치는 영향요소임을 확인하였으며, 근로자가 지각하는 정서적 몰입이 규범적 몰입을 매개로 지속적 몰입에 영향을 미치는 단계적 과정을 검증하였다. 특히, 보상지원전략이 조직원의 몰입에 미치는 영향이 근무제도(내근직과 재택근무)에 따라 상이하게 발생함이 실증하였다.

The purpose of this study was to investigate factors influencing role adaptation in newly employed nurses and the consistency between role expectations before employment and after one year of employment. The results of this study may contribute to strategy development towards positive role adaptation in newly employed nurses. The data used in this study were collected from 111 nurses, the sample was drawn from all newly employed professional nurses working at Y Medical Center in 1987. The data were collected longitudinally in the 2nd - 3rd weeks, the 3rd month and the 12th month after employment. The results of this study were as follows : 1. The degree of change the importance of factors influencing role adaptation and the length of time after employment were investigated. the result showed that the degree of change was the greatest within the first 3 months after employment. Important factors related to role adaptation were working conditions, the environment of the assigned ward and the work load. These factors always displayed high scores without any great change over time. New employees put more importance on practical factors which were obtained through experience in their jobs rather than on ideal factors Which they had considered more important while in school. 2. Consistency between role expectation before employment and after 12 month of employment was investigated. The highest consintency item was the expectation about the variety of Patients, and the highest inconsistency was the expectation about their own welfare. An average score of 69.07 points was achieved from a maximum of 125 points for the 25 items. showing that expectations for role development before employment were not fully satisfied. In conclusion the administraor should assess the initial expectation at the time of employment of new nurses and she / he should make clear to the new nurses that these expectations may not be realistic. In this way the administrator can provide more satisfactory conditions towards the expectations of the new nurses and help them towards positive role adaptation and reduction of role conflict. Newly employed nurses have high and unrealistic expectations about socialization to the profession from their nursing educational program. It is suggested that a transitional training program should be planned and carried out for newly employed nurses.

A Clinical Pathway(CP) is standard process to way of treat diseases or injuries which is adapted to each hospital based on National Clinical Practice Guideline(CPG). Since CP is standard guideline for doctors and nurses working in a hospital, making and modifying CP is one of the most important administrational work for hospital and also rare work because once it is fixed, it's not changed whether there are new kind of disease discovered or new treatment is developed. However, in present, patient's waiting time during hospital residence process, is discussed as service competitive for patients. In this research, we utilize process mining tool to verify patients treatment process follows CP with EMR(Electronic Medical Record) in a sample hospital, and suggest modifcation point of CP through verification.

The open approach to teaching school mathematics in the United States is an outcome of the collaboration of Japanese and U.S. researchers. We examine the approach by illustrating its three aspects: open process (there is more than one way to arrive at the solution to a problem; 2) open-ended problems (a problem can have several of many correct answers), and 3) what the Japanese call 'from problem to problem' or problem formulation (students draw on their own thinking to formulate new problems). Using our understanding of the Japanese open approach to teaching mathematics, we adapt selected methods to teach mathematics more effectively in the United States. Much of this approach is new to U.S. mathematics teachers, in that it has teachers working together in groups on lesson plans, and through a series of discussions and revisions, results in a greatly improved, effective plan. It also has teachers actively observing individual students or groups of students as they work on a problem, and then later comparing and discussing the students' work.

In a basic engineering design class, first year engineering department students learn about engineering design relevant theories and carry out simple projects in teams. By doing a group project in this subject, students develop basic skills such as creativity, teamwork, communication, and problem solving. Before, class proceeded in a way where teams were randomly configured in the beginning of semester and students began working on their project immediately. However, this research introduces a new method where at the beginning of the semester, students are assigned group assignments. Teammates are randomly chosen and constantly switched so that students get a chance to work with different people and experience diverse styles and characteristics. Then, they autonomously form into teams with people they work best and carry out their project. We present the behavior of a monkey robot that recognizes emotions as a case of applying the proposed method. The feedback from the students suggest that this proposed team forming method serves to be effective especially since students who were not aware of other students' characteristics can get to know one another better and form a productive team.

The rapid growth of economy improves not only the life quality of people in this modern society but also standards of value in connection with how those people would spend money as they engage in various leisure and cultural activities. That being the case, hotels are currently changing into places of new concepts depending on those new lifestyles of these people, and in those new places, people can entertain and experience as enjoying cultures. The marketing collaboration of the hotels with brands can be used as a more inclusive way to enhance brand images. In addition, as having infinite possibilities of the collaboration's being able to create a new-concept space with an identity of a brand included, this collaboration makes it possible for the design hotels to decorate their interior spaces differently from those of other hotels. In the light of that, the brand collaboration is basically divided into three groups which are the fashion collaboration, the technique collaboration and the designer collaboration, and the brand collaboration is also able to express the interior spaces of the design hotels as working on those six components, such as reproduction, events, alteration, messages, culture and image. After all, through the brand collaboration marketing, this thesis expects an interior design of a new-concept design hotel which would play a role as a complex cultural space.

Objectives: This study aimed to provide basic data for the development of clinical practice-related education program by analyzing the effects of grit, job satisfaction, and retention intention on transition shock of new dental hygienists. Methods: From April 19 to July 4, 2022, the data was collected from 200 new dental hygienists working for dental hospitals/clinics. Using the SPSS Statistics ver. 22.0, this study was conducted the t-test, one-way ANOVA, Pearson's correlation analysis, and multiple regression analysis. Results: There were positive correlations between grit, job satisfaction, and retention intention, a negative correlation between grit and transition shock, a positive correlation between job satisfaction and retention intention, a negative correlation between job satisfaction and transition shock. and a negative correlation between retention intention and transition shock. As the factors affecting transition shock, lower pay and main performance of medical cooperation work increased transition shock. When job satisfaction and retention intention were higher, transition shock decreased. Conclusions: In order to reduce transition shock of new dental hygienists, it would be necessary to operate clinical practice-related training program, and also to establish a training environment similar to the clinical site/context/situation similar to clinical context/situation.
