Recently, vision-based dynamic deflection measurement techniques have significant interests and are getting more popular owing to development of the high-quality and low-price camcorder and also image processing algorithm. However, there are still several research issues to be improved including the self-vibration of vision device, i.e. camcorder, and the image processing algorithm in device aspect, and also the application area should be extended to measure three dimensional movement of floating structures in application aspect. In this study, vision-based dynamic motion measurement technique using multiple targets is proposed to measure three dimensional dynamic motion of floating structures. And also a new scheme to select threshold value to discriminate the background from the raw image containing targets. The proposed method is applied to measure the dynamic motion of large concrete floating quay in open sea area under several wave conditions, and the results are compared with the measurement results from conventional RTK-GPS(Real Time Kinematics-Global Positioning System) and MRU(Motion Reference Unit).

This study presents the design and manufacture of a self-contained breathing apparatus SCBA wireless communication module with a multipoint simultaneous full-duplex communication system to enable communication between team members wearing the SCBA system. It is necessary for fire-fighters to wear the SCBA system during extinguishing and rescue work at the fire site. Evaluation of the team communication module confirmed the feasibility of communication over more than 500 m in the test condition based on the line of sight. By implementing the Ad-hoc function, it was confirmed that the communication distance could be extended to 128 m by automatic routing up to 3 hoc. The vertical distance inside the building for successful communication was up to the 5th floor in the open staircase and up to the 3rd floor in the partitioned staircase. Furthermore, the performance testing of the communication module assuming a fire situation, confirmed that five team members correctly recognized the standard abbreviation of fire and wireless communication without a separate PTT key operation. In addition, the flame resistance was verified by exposing the module to a flame at 950 ± 50 ℃ for 5 s and then immediately extinguishing the flame.

This empirical research is aimed at testing the relationship of the big five personality traits namely openness to experience, extraversion, consciousness, agreeableness, neuroticism, and risk aversion with the investment intention of individual investors belonging to Balochistan, Pakistan. The primary data is collected through a self-administered questionnaire (a structured form that consists of a series of closed-ended and open-ended questions) from a sample of 397 active individual investors belonging to different districts of the province. The data is empirically analyzed by applying the Partial Least Square (PLS) path modeling technique by using the estimation package available in Smart-PLS. The findings of this study suggest that all the variables are statistically significant with investors' investment intention with risk aversion as the strongest predictor. Moreover, openness to experience, extraversion, consciousness, agreeableness, and risk are significantly and positively related to an investor's investment intention, whereas neuroticism is negatively related to an investor's investment intention. The results extended by this study can be used by financial planners and investment bankers to channelize the available financial resources in diversified portfolios. The results will help financial planners to make available diverse investment alternatives for investors in Balochistan, thus catering to their unique needs. Academia must offer courses on contemporary finance paradigm based on behavioral finance to enable future business graduates to make wise financial decisions.

Career indecision has long been a phenomenon of interest to parents, faculty, school counselors, and others who advise young adults on their career choices. The earliest work on career indecision focused almost exclusively on the negative consequences that young adults faced as a result of lack of self-insight into their own skills and abilities, lack of specific information about various occupations and labor markets, and fear of commitment to any career path in particular. More recently, researchers have noted that some of the short run negative consequences of early career indecision may ultimately lead to long-term positive consequences, particularly if better person-occupation fit is achieved as a result of young adults' extended search behavior. Extroversion, agreeableness, emotional stability, and openness showed to have negative effects on indecisiveness. In case of lack of job information, only extroversion and emotional stability showed to have negative effects on indecisiveness, and openness showed negative effect. Indecisiveness has negative effect on preparatory job search behavior. Lack of information has negative effect on preparatory job search behavior and active job search behavior.

This paper is focused on Damheonseo(湛軒書), an anthology written by Hong Daeyong, and I deal with Chinese Architectural views which he had experienced in his itinerary to Beijing, and the vivid pictures of Joseonkwan (called the Koryo or Joseon Embassy) located in Beijing at that time. He was a scholar of great erudition over astronomy, mathematics, military science, politics, and so on. He was interested in practical sciences at early time, and criticized secular scholars full of vanity who had presented purposeless articles. In his age of 35, Qianlong(乾隆) 30 (1764, Youngjo 41), he, a military escort, accompanied by Hong Uk, Joseon envoy and his uncle. Before his itinerary, he self-studied Chinese. Also, during a long journey he got new experiences and information around each area, deviating his group whenever he had some times. He could get more variant experiences than others because of his character full of curiosity, and his observations from the vivid lives of the time helped us get various views between Chinese and Korean architecture. Likewise, although he denounced Qing(淸) scathingly as a barbarian, he mentioned several points about the characteristics of Chinese architecture at that time. First of all, totally Chinese architecture had strong rational and practical points. Secondly, based on bountiful products, buildings along streets shown in Chinese city had sophisticated compositions, and luxurious and magnificent appearances. Thirdly, using the brick from walls to houses was so universal. Fourthly, the layouts of building with three- or four-closed courtyard had very orderly shapes, and the structure of street was also so arranged. Finally, because of stand-up lives, the scales and appearances of interior space were even more extended, and storages were less developed than those of Joseon. As another points, I found that Joseonkwan was moved next to Shushangguan(庶常館)from Huidongnanguan(會同南館) around Hanlimyuan(翰林院), and had been remodeled into a house with Korean custom in using the inner spaces, although it was followed by a closed courtyard style. Likewise, I recognized that Ondols were sure to be established in all temporary houses during the journey to Qing, and felt their strong traditional residential custom in such mentions. Now that the past pictures have disappeared and ways of life and our values have been largely changed, this study has very important meaning in comparing the ancient Chinese and Korean architecture.

The goal of reconstruction following ablative therapy for intraoral cancer is the restoration of form and function to permit a return to activities of daily life. Traditional reconstruction includes split thickness skin grafts, myocutaneous flaps and, more recently, various free flaps. Free flaps provide higher level of functional recovery relative to that seen with other techniques but require the complexity of the technique and microvascular anastomosis and thus, extended surgical time and occasionally a second team for harvesting. The platysma myocutaneous cervical flap is a possible alternative for intraoral reconstruction. It is thin and pliable like the tissue provided by the radial forearm free flap. It can be harvested with enough tissue to close most head and neck ablative defects. There is virtually no donor site morbidity involved. This study evaluated 7 patients affected by intraoral squamous cell carcinoma (SCC). All patients underwent the resection of intraoral SCC with neck dissection and subsequent intraoral reconstruction with the superiorly based platysma myocutaneous cervical flap. Flap-related complications occurred in 3 patients. Adjuvant radiation therapy was performed in 3 patients. Average follow-up was 24.1 months after surgery, with a range of 8 to 42 months. All patients presented self assessment of discomfort associated with intraoral recipient sites and cervical donor sites. However, the neck function measured by two-inclinometer technique was within the normal range during relatively long term follow-up period. Our study concluded that superiorly based platysma myocutaneous cervical flap is good alternative to free flaps, especially for relatively smaller defects and for the defects appropriate for the rotation arc of the flap.

Based on the place of its origin, pear tree (Pyrus spp.) is largely divided into European pears (P. communis, cultivated mainly in Europe and the U.S.) and Asian pears (P. pyrifolia, P. bretschneideri, and P. ussuriensis, distributed and grown in East Asian countries including China, Japan, and Korea). Most pear trees have 17 chromosomes (diploidy, 2n=2x=34). Their genetic studies and precise cultivar breeding are highly restricted by conditions such as self-incompatibility controlled by S-locus and juvenility as one major character of fruit crops. Genetic studies on Pyrus have been promoted by the development of various molecular markers. These markers are being utilized actively in various genetic studies, including genetic relationship analysis, genetic mapping, and QTL analysis. In addition, research on pear genetic linkage maps has been extended to studies for the identification of QTL for target traits such as disease resistance and genetic loci of useful traits. NGS technology has radically reduced sequencing expenses based on massive parallel reactions to enable high-capacity and high-efficiency. NGS based genome analyses have been completed for Chinese pear 'Danshansuli' and European pear 'Bartlett'. In Korea, GWAS for agricultural valuable traits such as floral structure, ripening, and total soluble contents have been conducted through resequencing. GBS has been performed for 'Whangkeumbae', 'Cheongsilri', and 'Minibae'.

Parish nursing is a community health nursing role developed in 1983 by Lutheran Chaplain Granger Westberg. An increasing emphasis on holistic care, personal responsibility for a healthy lifestyle, and changes in healthcare delivery systems have undoubtedly facilitated the establishment of an innovative nursing role in the community. Parish nurses are functioning in a variety of church congregations of various denominations. The parish nurse is a educator, a personal health counselor, a coordinator of volunteers. The parish nurses helps people relate to the complexed medical care system and assists people to integrate faith and health. The purpose of this study is to investigate what the korean parishioners want in parish nursing and what type of role expectation from parish nurse. The subjects were 1138 parishioners of 23 churches of various denominations in nationwide Korea. Data were collected by self-reported question naires from Feb 4 to June 25. 1999. The data were analyzed by using percentage. frequency. $x^2-test$. multiple Response set with SPSS program. The results are as follows: 1. Desired parish nursing contents by parish nurses are: psychological counselling(23.4%) out of private counselling. stress management(21.1 %) out of private health education. Emergency care(14.1%) out of group health education. Blood Pressure check-ups (19.0%) out of Health check ups. home visiting(44.9%) out of patient visiting method. B T. pulse, respiration and blood pressure check(15.0%) in Care to serve in home visiting. spiritual preparation to accept the death(41.7%) in hospice care, advices to choice of medical treatment using guide(50.1%) in introducing and guiding of health care facilities, pray(21.7%) in spiritual care' faith support. 2. Desired Health Teaching Content According to Period of Clients by Parish Nurse are: Vaccination(22.5%) in infant and toddler health management. sexual education(25.3%) in adolescent health management. prenatal care (29.5%) in pregnant health management. osteoporosis prevention and management (22.4%) in Middle aged health management. dementia prevention and management(25.5%) in elderly health management. 3. The expectant role from parish nurse is spiritual care faith support(14.1%). patient visiting care(13.2%), hospice care(12.9%), private counseling(12.8%), health check ups (11.1 %), volunteer organization and training out of believer(11.0%), private health education (9.3%), group health education (8.3%). 4. In Necessity of Performing Parish Nursing according to Region, Most(over 95%) responded that nursing program is needed. so there is no significance between regions. In Performing Parish Nursing in their church, Most(92.2%) responded they want to perform program. 5. In case of performing parish nursing, 52% out of the subjects responded they want to participated in parish nursing volunteer's activity, for example. to be in active to be a companion to chat(42.1%), necessity support (25.3%), donation support(25.0%), exercise support(18.2%), vehicles support (9.9%). As a result. in holistic care and spiritual care, the need of parish nursing and the role expectation from parish nurse are very high among korean believers. Therefore, I suggest parish nursing centering around Taegu and Kyungbuk province should be extended to nationwide. For extending parish nursing program. more active advertisement and research is needed. After performing parish nursing program through out the country, further comparative research between regions should be practiced and Korean parish nursing program will be developed and activated.

Although Intelligent Tutoring System(ITS) offers individualized learning environment that overcome limited function of existent CAI, and consider many learners' variable, there is little development to be using at the sites of schools because of inefficiency of investment and absence of pedagogical content knowledge representation techniques. To solve these problem, we should study a method, which represents knowledge for ITS, and which reuses knowledge base. On the pedagogical content knowledge, the knowledge in education differs from knowledge in a general sense. In this paper, we shall primarily address the multi-complex structure of knowledge and explanation of learning vein using multi-complex structure. Multi-Complex, which is organized into nodes, clusters and uses by knowledge base. In addition, it grows a adaptive knowledge base by self-learning. Therefore, in this paper, we propose the 'Extended Neural Logic Network(X-Neuronet)', which is based on Neural Logic Network with logical inference and topological inflexibility in cognition structure, and includes pedagogical content knowledge and object-oriented conception, verify validity. X-Neuronet defines that a knowledge is directive combination with inertia and weights, and offers basic conceptions for expression, logic operator for operation and processing, node value and connection weight, propagation rule, learning algorithm.

Human has noticed a beautiful natural scenery and appreciated it as a scenic site by giving meaning to it and evaluating it. How the beautiful natural scenery was appreciated as a scenic site depends on natural features, social and cultural environments, and the current of the times. Mt. Jiri is the highest mountain in inland South Korea and keeps ancestors' history and culture intact. Joseon Dynasty literary men frequently mentioned Mt. Jiri as a tourist attraction where they could pursue and share their studies against its beautiful natural scenery. The countless literary men visited Mt. Jiri and some of them left their journeys as travelling records. This research aimed at apprehending travel routes of Chunwang Peak of Mt. Jiri based on the contents of travelling records and investigating the scenic site value of scenic resources as the literary men in Joseon Dynasty recognized. The scenic resources of Mt. Jiri were related to the change of the reason or motivation of person who climbed and it should be noted that there was a change of reason or motivation in climbing Mt. Jiri from a following of master's paths to discovery of a new trails. Thus, even if there was a difference in reason or purpose of natural scenic beauty, the concept of scenic sites of the past and the present day should be included into the extended meaning of scenic sites. This research aimed the routes of well-known literary men need to be developed as programs utilizing "the concept of ancient sages' footprints" and the development of these contents shall be used for vitalization and self-support of a regional economy.
