Autonomous speedsprayer operation was conducted using the developed FLC(Fuzzy Logic Controller). Orchard image and signals of ultrasonic sensors were processed in real time. The speedsprayer was modified to be steered by two hydraulic cylinders. The FLC has two inputs, direction of running and distance from obstacles. The operation time of hydraulic cylinders were inferred as output of the FLC. Field test results showed that the speedsprayer could be autonomously operated by the FLC along with the image processing and the ultrasonic sensors. The ultrasonic sensors didn't contribute to the improvement of guidance performance, but the speedsprayer could avoid trees or obstacles in emergent situations with them.

The survivability of a naval ship is the ability of the ship and its onboard systems to remain functional and continue a designated mission in man-made hostile environments. A passive decoy system is primarily used as a weapon system for improving the survivability of a naval ship. In this study, an engagement scenario-based simulation program was developed for decoy effectiveness assessments against an anti-ship missile (ASM), which tracks a target with sea-skimming and active radar homing. The program can explain the characteristics of a target ship, such as the radar cross section and evasive maneuvers, as well as the operational performance of the onboard decoy system, the guidance method of the ASM, and the engagement environment's wind speed and direction. This paper describes the theory and formulations, configuration, and user interface of the developed program. Numerical examples of a decoy effect assessment of a virtual naval ship against an ASM are presented.

Purpose: This study aimed to provide a theoretical basis for career anchors of nurses by defining and organizing its concept. Methods: Using the Walker and Avant concept analysis, a total of 29 articles were analyzed through a literature search in this study. Results: The career anchors of nurses are individual career choice motives, a self-concept where in competency and values are harmonized, which act as a desire for growth and development in nursing, and are actions that maintain careers. Additionally, they indicate the direction for achieving individual career goals and act as a core value expected of nurses by nursing organizations, indicating continuous and integrated professional growth and development of the nursing profession. Conclusion: The career anchors of nurses identified in the results contribute to securing patient safety, providing quality care through policies, institutionalizing bases for career development, preventing nurse turnover, and retaining skilled nurses.

This study is to implement a model of CPC-mentoring program based on the mentoring theory and research environment analysis as well as to present the operation case of teaching and learning in colleges. Major research results should use the practical research methods utilizing the statistical program in order to verify the effectiveness of the program of CPC-mentoring program by comparing the before with the after of running the CPC-mentoring program of the research objects, comparison group (61 people) and experiment group (33 people). After running the CPC-mentoring program, whether there was a certification's acquisition or not of the comparison group and the experiment group, a statistically significant difference between the comparison group 34.3% (21) and the experiment group 72.7% (24), (p<0.05) was shown. The goal of the students participating in the CPC-mentoring program was to help one another in order to obtain certification. moreover, by engaging in mutually developing human relationship activities thru various methods, such as adaptation of college life, development of sociality, graduation, etc., good cooperative relationships with one another as well as further development of the relationship was formed. CPC-mentoring program is neither doing only people that want nor being effective for people only that want. A successful matching will naturally lead to all success since mentoring is human relationships is the misunderstanding. The role of a mentoring coordinator(professor) for the operation of a successful CPC-mentoring program and for the application method of detailed CPC-mentoring program was set. In addition, by considering the connectivity with the counseling guidance (shared and individual guidance) of students, which is the characterization direction of technical department of the college, it is expected to make a positive contribution if utilized in a multilateral manner.

Primary teeth and the permanent successor must be understood as interdependent units, where each one of them interacts with and depends upon the other. The spread of pulpal inflammation in primary teeth to the periradicular tissues can lead to early eruption, enamel hypoplasia or hypocalcification, developmental arrest of permanent successor. Also the periapical inflammation cause permanent tooth displacement in various direction. We describe here two clinical cases of displaced permanent successor caused by periapical lesion of mandibular primary molar in children.

There are many ways to know the social and cultural level of each country. Among them, a museum are not only the best place to understand the history, the life style and the culture level. The most important constituent, which museum architecture has, are visitors, exhibition and communication between visitors. Exhibition space composition is the one of important things in museum architecture, and it's essential to show an intent of exhibition to visitors. This thesis has the purpose to provide the basic material through analyzing exhibition space composition and exhibition method of the theme museum and understanding the relativity of them so that the new theme museums can be designed in the Tight direction. So I chose the independence museum that opened within recent 10 years, finally middle & small size's theme museum were selected. The results from the case study are as follow. Firstly, the exhibition space unit of basic type and center-hall enter type had a one-way for gateway and used the exhibition of three or four faces. The exhibition space unit of around tile center-hall type and guidance type had the separated gateway and used the exhibition of one or two faces. Secondly, the exhibition method of selected museums was divided into the wall face type and the island type. The exhibition method of two faces mainly used in guidance type caused complicated visitor circulation. In that case, it seemed to be good that two walls were used alternately. Thirdly, there were visual type, audio-visual type, handling type and experiential type in the method of exhibition. The former two types were used mostly, and the latter two types were rarely used. Fourthly, the wall face type was inefficient for exhibition because given walls were supposed to be used. Therefore, it was more effective to use the wall face type and the island type together.
