Background: Although ultrasound-guided needle decompression (US-GND) can treat calcific tendinitis of the shoulder effectively, repeat procedures might be required for unresolved symptoms. We evaluated the overall clinical outcomes of US-GND with subacromial steroid injection and the final results and factors predisposing toward repeat procedures. Methods: Ninety-eight patients who underwent US-GND for calcific tendinitis of the supraspinatus/infraspinatus were analyzed between March 2017 and December 2018. The clinical outcomes (pain visual analog scale, functional visual analog scale [FVAS], and American Shoulder and Elbow Surgeons [ASES] score) and final subjective satisfaction were compared between groups A (single US-GND) and B (repeat US-GND). The factors predisposing toward repeated US-GNDs were analyzed. Results: We found that 59.3% (58/98) of patient ASES scores were ≥80, and 73.5% of patients (72/98) were satisfied with the outcome. Group B (n=14) demonstrated a significantly higher rate of dominant-arm involvement compared to group A (78.6% vs. 48.8%, p=0.046). However, initial calcification size, shape, number, density, subscapularis involvement, lavage, and procedure time did not differ significantly between the groups. Group B showed poorer final FVAS (7 [interquartile range, 6-8] vs. 8 [interquartile range, 7-9], p=0.036) and subjective satisfaction compared to group A (satisfied: 5 [35.7%] vs. 67 [79.8%], p<0.001]. Conclusions: US-GND with subacromial steroid injection is a viable treatment option for calcific tendinitis of the shoulder. Dominant-arm involvement was the only independent factor for repeated US-GND. Final outcome of repeated US-GND for unimproved patients was promising; however, these outcomes were poor compared to those of the patients who improved after the first procedure.

This paper investigates the group average-consensus and group formation-consensus problems for first-order multi-agent systems. The control protocol for group consensus is designed by considering the positive adjacency elements. Since each intra-group Laplacian matrix cannot be satisfied with the in-degree balance because of the positive adjacency elements between groups, we decompose the Laplacian matrix into an intra-group Laplacian matrix and an inter-group Laplacian matrix. Moreover, average matrices are used in the control protocol to analyze the stability of multi-agent systems with a fixed and undirected communication topology. Using the graph theory and the Lyapunov functional, stability analysis is performed for group average-consensus and group formation-consensus, respectively. Finally, some simulation results are presented to validate the effectiveness of the proposed control protocol for group consensus.

The purpose of this study was to analyze the view of housing of Korean and Japanese female university students. The view of housing was investigated in four stages-housing consciousness, resident opinion, ideal housing and housing needs-in this study. The data was collected through the self-entry questionnaire designed for this study and the sample of 400 in total, 200 cases form Korea and 200 cases form Japan. The results are as follows : The major findings of the housing consciousness were that Japanese female university students preferred the detached in the future. The resident opinion of Korean and Japanese female university students showed that the group space was more important than the private space. In the ideal image, they wanted psychological and physical comfort from their houses. In the housing needs, Korean have considered the distance of friend and family and been satisfied with interior design, whereas Japanese have considered the expression of social level and been satisfied with outdoor design.

This study was designed to evaluate the Personality characteristics of orthognathic surgery patients preoperatively and postoperatively through the MMPI. Comparison was made between the personality characteritics of preoperative and postoperative groups. Motivation for undergoing orthognathic surgery and postoperative satisfaction were examined through the questionnaire. Subjects used in this study consisted of 50 patients under presurgical orthodontic treatment and 22 patients who had received orthognathic surgery. From this study, the results were followings. 1. In preoperative patients group, all T-scores were within the normal range except for K-scale. The T-score of K-scale is 57.7, this showed that these patients underwent some or less stress. 2. In postoperative patients group, all T-scores were within the normal range. 3. Only in K-scale, there was statistically significant increase after surgery (p<0.05). 4. In male patients group, all T-scores were within the normal range except for that of preoperative K-scale. Postoperatively, there were statistically significant increase in K and Hs scales(p<0.05) 5. In female patients group, all T-scores were within the normal range. 6. Motivation for undergoing orthognathic surgery could be divided into 4 categories. esthetic goal($28.2\%$), functional goal($32.1\%$), TMJ problem($9.0\%$), and psychosocial reason($30.7\%$). 7. The degree of postoperative satisfaction was quite high($85.7\%$). $14.3\%$ of all patients were very satisfied, $71.4\%$ were satisfied, $9.5\%$ were neither satisfied or dissatisfied, and $4.8\%$ were very dissatisfied.

The research objective was to identify the effect of various instruction media on improving students' foodservice management competencies and for increasing class satisfaction. The research involved a comparison of two student groups. One group consisted of students who attended a lecture-based food purchasing class (Group A). The other group was students who attended the same class, and who also used various media as well as receiving the lecture (Group B). The results were as follows: 1) After a 16 week program, Group B perceived their procurement management competencies to be higher than those of Group A, especially in setting up purchasing goals, marketing research, and using computer systems for procurement; 2) In terms of class satisfaction, it was also observed that Group B was more satisfied with food purchasing class than was Group A. Group B gave high scores, especially in effective utilization of media, increasing motivation, and understanding; 3) Group B perceived that various instruction media was helpful for developing their procurement management competencies. Respondents evaluated the usefulness of media in the following order: using Power Point watching videos, visiting web-sites for food purchasing class, and surfing the World Wide Web. The results of the research show that using various instruction media for food purchasing classes would improve students' foodservice management competencies. Therefore, instructors who teach foodservice management related courses should consider developing teaching strategies that apply various instruction media for students to enhance their foodservice management competencies and to increase class satisfaction.

Purpose: The objective of this study was to determine the appropriateness of Emergency Medical Service's (EMS's) triage and transport of severely injured patients in Busan and Kyungnam, Korea. Methods: The medical records of the Emergency Medical Information Center were retrospectively reviewed from January 1, 2010 to December 31, 2010. We identified the number of patients that should have been transferred from a secondary to a tertiary hospital according to the EMS field triage protocol. Results: In a total of 472 cases requests to be transferred to a third hospital were made through the Emergency Medical Information Center. Of these, 207 patients(43.9%) should have been transferred to a tertiary hospital according to the EMS field triage protocol. Among them, thirty-three(15.9%) patients satisfied step 1, 15(7.0%) satisfied step 2, and 117(56.5%) satisfied step 3. Twenty-three(11.1%) patients satisfied both steps 1 and 3. Conclusion: We found the triage by the EMS in the transfer of severely injured patients to a tertiary hospital to be inappropriate and re-education of EMS personnel regarding the EMS field triage protocol is needed. Because many patients are transferred from a secondary to a third hospital, we suggest changing the EMS field triage protocol to expand the severe injury criteria. A need exists to authorize secondary hospitals to transfer severely injured patients directly because there are no trauma centers in Korea.

A modified direct bonding technique employing a wet chemical deposition of $SiO_2$ film on a wafer surface to be bonded is proposed for the fabrication of Si-$SiO_2$-Si structures. Structural and electrical quality of the bonded wafers is studied. Satisfied insulating properties of interfacial $SiO_2$ layers are demonstrated. Elastic strain caused by surface morphology is investigated. The diminution of strain in the grooved structures is semi-quantitatively interpreted by a model considering the virtual defects distributed over the interfacial region.
