Conventional occupational therapy (OT) is conducted under the observation of an occupational therapist, and there are limitations in measuring and analyzing details such as degree of hand tremor and movement tendency, so this important information may be lost. It is therefore difficult to identify quantitative performance indicators, and the presence of observers during performance sometimes makes the subjects feel that they have to achieve good results. In this study, by using the Unity3D and artificial intelligence (AI) speaker, we propose a system that allows the subjects to steadily use it by themselves and helps the occupational therapist objectively evaluate through quantitative data. This system is based on the OT of the sensory integration approach. And the purpose of this system is to improve children's activities of daily living by providing various feedback to induce sensory integration, which allows them to develop the ability to effectively use their bodies. A dynamic OT cognitive assessment tool for children used in clinical practice was implemented in Unity3D to create an OT environment of virtual space. The Leap Motion Controller allows users to track and record hand motion data in real time. Occupational therapists can control the user's performance environment remotely by connecting Unity3D and AI speaker. The experiment with the conventional OT tool and the system we proposed was conducted. As a result, it was found that when the system was performed without an observer, users can perform spontaneously and several times feeling ease and active mind.

A field study was performed to test effectiveness of a bloluminescent genetically engineered microorganism (GEM) for bioremediation process monitoring and control. The study employed Pseudomonas fluorescens HK44 that was the first strain approved for field application in the U.S. for bioremediation purposes. HK44 contains lux gene fused within a naphthalene degradative pathway, allowing this GEM to bioluminesce as it degrades naphthalene as well as substituted naphthalenes and other polycyclic aromatic hydrocarbons (PAHs) , Results showed that HK44 was maintained in both PAH-contarninated and uncontaminated soils even 660 days after inoculation. HK44 was able to produce bioluminescence in response to PAHs in soil. Although effectiveness of chemical remediation was not assessed due to heterogeneous distribution of contaminants, decreased concentration of naphthalene was shown in the soils, Taken together, HK44 was useful for in situ bioremediation process monitoring and control. This work is so far the only field release of a GEM for bioremediation purposes.

Jeju, the biggest island in Korea, was registered as a World Natural Heritage in 2007. Recently, it was also voted as one of the New Seven Wonders of Nature. The need for academic awareness and tourist values on Jeju Island are understood. Gal-ot, one of the ten symbols for Jeju, is known for working clothes in general, despite its potential for cultural products because of its regional uniqueness and useful functional advantages. The authors conducted a comprehensive literature review and researched market trends of Gal-ot stores in Jeju to present development directions for cultural goods and to contribute to local economic improvement. Most stores were located in a semi-residential area and Jeju-si in Jeju Special Self-Governing Province. Most products were not available for sale due to difficulties in the production process and online utilization. High prices and similar color, fabric and style hurt competitiveness. Various experiencing programs of Gal-ot and persimmon dyeing were necessary to expand the main target from residents to tourists. Also, marketing strategies using the internet and design plans reflecting current trends were needed. This study would contribute to prepare developmental projects of cultural product and result in economical advantages on Jeju Island.

Introduction : Animal studies cannot be applied directly to Occupational Therapy(OT) intervention protocol. However, animal models still provide essential evidences and knowledge to improve OT practice and to develop OT theories as well as human studies do. The purpose of this scholarly paper is to explore the potential of animal models to inform OT theory and practice particularly as it relates to neuroscience. Body : The animal models provide related knowledge for a better understanding of the mechanism of diseases and related neural networks. Based on this knowledge, researchers can test their hypothesis of neural disease. In addition, accumulated animal studies contribute to introduce the new approaches to human diseases and to improve the effectiveness of treatment. Conclusions : Animal models of neurological disease are critical and have the potential to improve OT practice and theory in many ways. Therefore, OT researchers need to pay more attention to animal models in addition human studies.

Purpose : This study aims to investigate the awareness of occupational therapists among managers and directors of adult day care centers in Korea to explore the cause of the low employment rate of these therapists and offer the results as basic data that can be used to expand occupational therapy at adult day care centers. Methods : This study collected data by conducting an online questionnaire with managers and directors of adult day care centers located in Seoul, Busan, Incheon, Daejeon, Gwangju, and Ulsan. A total of 70 completed questionnaires were divided into two groups a 'group with experience in occupational therapy information (OT experience)' and a 'group with no experience in occupational therapy information (OT inexperience)' and analyzed. Results : First, the 'OT experience' was found to have higher levels of awareness of the scope of work of occupational therapists than the 'OT inexperience'. Second, significant differences were found in the degree of awareness and necessity of occupational therapists and plans to employ occupational therapists later between the 'OT experience' and the 'OT inexperience'. Third, it was shown that there were significant correlations between whether the respondents were familiar with occupational therapy and the degree of awareness and necessity of occupational therapists and plans to employ occupational therapists later. Conclusion : Based on these findings, the following measures are recommended to expand the area of occupational therapy in adult day care centers, the need for occupational therapists should be mentioned in the health and welfare-related education for workers at these adult day care centers, policies such as a medical fee system for occupational therapy at these adult day care centers should be prepared.

This study investigates costumes for ball jointed dolls under the theme of Bok-yo(服妖): The Lady in Early-middle Joseon with relic costumes as a reference. The Bok-yo style was spread universally for Joseon women in the $15^{th}-16^{th}$ centuries, but it is an uncommon theme in the area of media and traditional costume for dolls. Bok-yo (curious outfit), consisted of a Dang-jeogori with a golden brocade in the front bottom, manlike Jang-ot, wide Chima, and Jang-ot was dressed between Chima and the Dang-jeogori. To make correct patterns and approvals for idle bodies of female ball-jointed dolls, darts are added in the front vertical line and center back of the golden brocade Dan-jeogori for Joseon ladies. The pattern of the golden brocade Chima is made as a trapezoid shape for the thin waist of a doll, and the length of a deep-greened silk gauze The Jang-ot increased because of the length of the doll's legs. In addition, the kinds of investigated accessories, hair, traditional underwear for dolls are limited. Suggested is a closer cooperation between the investigated costume designers, doll companies, and accessory makers for the future market of ball jointed dolls.

In this paper, a cooperative relaying protocol called soft-decision-and-forward (SDF) with multiple antennas in each node is introduced. SDF protocol exploits the soft decision source symbol values from the received signal at the relay node. For orthogonal transmission (OT), orthogonal codes including Alamouti code are used and for non-orthogonal transmission (NT), distributed space-time codes are designed by using a quasi-orthogonal space-time block code. The optimal maximum likelihood (ML) decoders for the proposed protocol with low decoding complexity are proposed. For OT, the ML decoders are derived as symbolwise decoders while for NT, the ML decoders are derived as pairwise decoders. It can be seen through simulations that SDF protocol outperforms AF protocol for both OT and NT.

Today, IT organizations perform projects with vision related to marketing and financial profit. The objective of realizing the vision is to improve the project performing ability in terms of QCD. Organizations have made a lot of efforts to achieve this objective through process improvement. Large companies such as IBM, Ford, and GE have made over $80\%$ of success through business process re-engineering using information technology instead of business improvement effect by computers. It is important to collect, analyze and manage the data on performed projects to achieve the objective, but quantitative measurement is difficult as software is invisible and the effect and efficiency caused by process change are not visibly identified. Therefore, it is not easy to extract the strategy of improvement. This paper measures and analyzes the project performance, focusing on organizations' external effectiveness and internal efficiency (Qualify, Delivery, Cycle time, and Waste). Based on the measured project performance scores, an OT (Opportunity Tree) model was designed for optimizing the project performance. The process of design is as follows. First, meta data are derived from projects and analyzed by quantitative GQM(Goal-Question-Metric) questionnaire. Then, the project performance model is designed with the data obtained from the quantitative GQM questionnaire and organization's performance score for each area is calculated. The value is revised by integrating the measured scores by area vision weights from all stakeholders (CEO, middle-class managers, developer, investor, and custom). Through this, routes for improvement are presented and an optimized improvement method is suggested. Existing methods to improve software process have been highly effective in division of processes' but somewhat unsatisfactory in structural function to develop and systemically manage strategies by applying the processes to Projects. The proposed OT model provides a solution to this problem. The OT model is useful to provide an optimal improvement method in line with organization's goals and can reduce risks which may occur in the course of improving process if it is applied with proposed methods. In addition, satisfaction about the improvement strategy can be improved by obtaining input about vision weight from all stakeholders through the qualitative questionnaire and by reflecting it to the calculation. The OT is also useful to optimize the expansion of market and financial performance by controlling the ability of Quality, Delivery, Cycle time, and Waste.

Background: Long-term oxygen therapy (LTOT) improves the survival of patients with hypoxemia due to chronic respiratory diseases. The clinical outcomes of LTOT are strongly associated with patient adherence. To improve the adherence of patients, physicians have focused on the efficacy of LTOT. However, poor adherence may stem from patients' perceptions of LTOT. Herein we evaluated patients' perceptions of LTOT affecting adherence. Methods: We conducted a cross-sectional survey study using descriptive, open, and closed-ended questionnaire. Patients using oxygen therapy (OT) or requiring it but avoiding OT responded to the questionnaires at three university hospitals. Results: Seventy-nine patients responded to the questionnaires. The number of patients using home and portable OT was 69 (93%) and 37 (46.3%), respectively. Patients with good adherence were 22 (30.1%). Among patients with good adherence, 90.9% used oxygen according to physicians' prescriptions whereas only 37.3% of those with poor adherence followed physicians' prescriptions (p<0.01). The reasons for avoiding using home OT were fear of permanent use (50%), unwanted attention (40%), and lack of symptoms (40%). They avoided portable OT because of unwanted attention (39%), heaviness (31.7%), and lack of symptoms (21.6%). Conclusion: Patients on LTOT had the perception of the misunderstanding the effects of OT and of psychosocial barriers to initiate or use LTOT. Considering these findings, health professionals need to provide effective education on the purpose of LTOT to improve patient adherence to OT and provide sufficient support for the management of psychosocial barriers in patients using LTOT.
