The artifacts in sonography is not always harmful. Sometimes it is beneficial for the evaluation of the water contents of the soft tissue and estimating the degree of inflammation and character of the regenerated tissue indirectly using artifacts such as acoustic shadowing and the enhanced transmission. It can also be useful to evaluate the possibility of aspiration of the calcifies masses by knowing of the contents of the water among them. Unlike the MRI it is useful to get real time informations with low cost in diagnosis and treatment of the soft tissue disease usinf artifacts in sonography.

Recently, research on the self-healing of concrete using bacteria has been actively conducted. The self-healing method using bacteria has a low self-healing rate and the surrounding environment of the fracture site is very important. A previous study to solve this problem involves the manufacture of capsules using 3D printing. Fracture position control was an important topic in 3D printing-based capsules. In this study, to compensate for the shortcomings of existing studies, a capsule capable of selective destruction location control was produced using PDMS-based molds that are not restricted by the environment. Resin capsules were prepared for each part using several molds and a bonding surface was arranged. In order to verify this on the bonding surface, fracture strength and wave unit values were analyzed through a three-way compression experiment. It can be seen that as the curing time increases, the deviation between samples decreases. In addition, through experiments, it was confirmed that the junction surface and wave unit values coincide in all three directions. It can be used for self-healing research using various solutions.

Purpose: The purpose of this study was to evaluate the repair integrity and clinical outcomes of delaminated tears following arthroscopic layered suture bridge rotator cuff repair in a prospective fashion. Materials and Methods: A consecutive series of 67 patients with delaminated rotator cuff tears who underwent surgery using the arthroscopic Layered Suture Bridge Technique were followed prospectively. Of 67 shoulders, 26 patients were male and 40 patients were female (one patient had bilateral tears); the mean age was 58.8(40~76) years. The clinical evaluation was performed according to ASES, UCLA, and KSS (Korea Shoulder Scoring System) scores with an average follow up period of 33 months. Repair integrity was estimated using MRI, which was performed six months postoperatively. Results: The average clinical outcome in ASES, UCLA, and KSS scores showed significant improvement at the time of the final follow-up compared to preoperatively, from 50.2 to 92.3, 15 to 31.3, and 54.4 to 90.7, respectively (p<0.001 for all scores). Follow up by MRI showed that 16 shoulders had a type-I; 14, a type-II; five, a type-III; two, a type-IV; one, a type-V re-tear. The overall rate of re-tear (types IV and V) was 7.9%. Conclusion: Use of the Arthroscopic Layered Suture Bridge Technique can result in improved functional and structural outcome in cases of delaminated rotator cuff tear.

The purpose of this study is to evaluate the magnetic property change of the nuclear reactor vessel steel irradiated by fast neutrons using $M{\ddot{o}}ssbauer$ spectroscopy, and the effects of the defects produced by neutron irradiation on the changes using X-ray diffraction. The specimens, fabricated with the dimension of $23mm{\times}18mm{\times}70{\mu}m$, were irradiated by neutron fluence from $10^{12}n/cm^2\;to\;10^{18}n/cm^2$ at 343K. Throughout the experiments, it is understood that (1) the X-ray diffraction measurement shows that the change of crystal nature is started at the irradiation of $10^{16}n/cm^2$ and a crystal structure has been severely damaged at the irradiation over $10^{17}n/cm^2$, (2) the analysis of the $M{\ddot{o}}ssbauer$ spectra has shown that magnetic transition phenomena occur at the irradiation over $10^{17}n/cm^2$ and (3) both methods can be utilized as nondestructive test methods for the embrittlement evaluation of materials irradiated by fast neutrons.

This study analyzes the spectrum of recommended books for adults included in the bibliotherapy book lists commonly used in libraries and organizations in the UK, US, and Korea. While the recommended book lists in the UK and US retain a diverse range of books relevant to the practitioners' needs, the Korean bibliotherapy book lists are mostly made up of non-fiction self-help books regardless of where the bibliotherapy service is provided. In the subcategory of the bibliotherapy book lists in the UK and US, aside from fictions, books on "health, fitness, dieting" including medical books rank higher than any other kind, which shows that bibliotherapy claims to have therapeutic effects in those organizations. In Korean bibliotherapy book lists, on the other hand, so-called "psychology books impregnated with self-help ideology" take up more than 60%. With the prospect of bibliotherapy as an interdisciplinary practice in mind, I suggest that bibliotherapy should draw upon the insights from humanities in order to help participants have time for deep introspection and attain inner maturity rather than just try to restore their normal conditions before the crisis.

The purpose of therapeutic approach of humanities, including literary therapy, is ultimately encourage the growth and the development of human being rather than the development of therapeutic techniques for eradicating symptoms. This paper is noteworthy as to the fundamental work for using folktales at therapy sessions. It may be argued that therapy is the process of searching clients' own development history and accepting current challenges in relation to overall context of their own lives and this may lead to the growth clients. In this regard, this paper attempts to set up the selection criteria for folktales to be effectively applied in therapy sessions. The author of the paper argued in her previous paper that folktales may be effective in terms of self-understanding of clients. Folktales can assist clients regarding the objectification of their issues by projecting and exposing their problems. Therefore, this paper argues the method for selecting proper folktales to stimulate of clients" developmental challenges and ultimately to expose them. The first groundwork for this is understand contents of folktale as to general problems of life and view it as the development of one's entire life. The challenge of client is personal and unique but at the same time it is problems of general development process. The author examines the need for developmental approach of literary therapy and attempts to compose a classification framework for understanding folktales as to developmental process. This may use at literary therapy sessions to select proper folktales based on clients' complaining issues and their developmental age. The criteria also can be used as the basis of clients" reaction on folk-tales.

The main purpose of this study is to study the effect of a program to improve self-esteem and positive thinking in middle-aged women using Buddha Ball meditation. In order to achieve this research purpose, the subject of this study was middle-aged female Buddhists at Temple H in Busan who were interested in 'Buddha Ball'. For the analysis method, empirical analysis was performed using the One Group Pretest-Posttest Design of this study. The main research results are as follows. First, as a result of examining the effect of Buddha Ball meditation on the quality of life, it could be seen that the overall quality of life had a significant positive (+) effect on the experimental group. Second, as a result of examining the effect of Buddha Ball meditation on self-esteem, it could be seen that self-esteem had a significant positive (+) effect on the experimental group. Third, as a result of examining the effect of Buddha Ball meditation on positive thinking, it could be seen that the entire positive thinking had a significant positive (+) effect on the experimental group. Based on these research results, the main conclusion was that the Buddha Ball, a healing meditation tool using the sound wave energy, had a positive effect on the self-esteem and quality of life of middle-aged women Buddhists. Accordingly, it is judged that the Buddha Ball meditation program has a positive use value for middle-aged women who are experiencing more complex psychological difficulties due to individual, family, and social environmental conditions. In addition, by preparing a system that can actively utilize the Buddha Ball meditation program educationally and politically, the implications of the justification and necessity of using it to improve the self-esteem, positive thinking and quality of life of middle-aged women were presented.

Statement of problem: The clinical use of electric and electomagnetic fields for fracture healing applications began in the early 1970s. Since then, several technologies have been developed and shown to promote healing of fractures. Developments of these devices have been aided in recent years by basic research and several well controlled clinical trials not only in the medical field but in dentistry. Purpose: The purpose of this study was to compare alveolar bone reduction following immediate implantation using implants onto which magnets were attached in fresh extracted sockets. Material and methods: Four mongrel dogs were involved. Full buccal and lingual mucoperiosteal flaps were elevated and third and fourth premolars of the mandible were removed. Implants with magnets and implants without magnets were installed in the fresh extracted sockets and after 3 months of healing the animals were sacrificed. The mandibles were dissected and each implant sites were sampled and processed for histological examination. Results: The marginal gaps that were present between the implant and walls of the sockets at the implantation stage disappeared in both groups as a result of bone fill and resorption of the bone crest. The buccal bone crests were located apical of its lingual counterparts. At the 12 week interval the mean of marginal bone resorption in the control group was significantly higher than that of the magnet group. The majority of specimens in magnet group presented early bone formation and less resorption of the buccal marginal bone compared to the control group. Conclusion: Within the limitations of this study, it could be concluded that implants with magnets attached in the early stages of implantation may provide more favorable conditions for early bone formation and reduce resorption and remodeling of marginal bone.

Microcapsules containing the suspension of conducting materials such as carbon nanotube (CNT) or polyaniline (PANI) were prepared by in-situ polymerization of melamine and formaldehyde. Stable microcapsules were prepared and the mean diameter of the observed microcapsules was in the range of $10-20{\mu}m$. The surface morphology and chemical structure of microcapsules were investigated using optical microscope (OM), scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FT-IR). The thermal properties of samples were investigated by thermogravimetric analysis (TGA). The conductivity of ruptured microcapsule containing the suspension of CNTs or PANIs in tetrachloroethylene and Isopar-G was measured. As the amount of CNTs and PANIs in the core of microcapsules increased, the measured current increased. Conductivity measurement results suggest that poly (melamine-formaldehyde) based core-shell microcapsules could be applied to self-healing electronic materials systems, where CNTs or PANIs bridge a broken circuit upon release.

Sternoclavicular septic arthritis is a rare condition and it is usually related to predisposing conditions like intravenous drug abuse, diabetic mellitus, trauma and so on. A delayed diagnosis of this disease may cause severe complications like mediastinitis and chest wall abscess. Computed tomography or magnetic resonance imaging is needed to evaluate the complications. If the above complications are present, then joint resection should be considered. We report here on a case of a 52-year-old man who was diagnosed with primary sternoclavicular septic arthritis and he had no predisposing conditions. The pathogen on the aspiration-culture was S. aureus and it was susceptible to cefminox. The patient was cured with administering only antibiotic therapy for 6 weeks; intravenous cefminox therapy for 4 weeks followed by oral cefminox therapy for 2 weeks.
