Purpose:The effectiveness of transdermal buprenorphine patch on the patients with frozen state of frozen shoulder was evaluated. Materials and Methods: Between March and September in 2013, 127 patients with pain and limited range of motion in shoulder joint over 6 months were included. Every patient was confirmed the diagnosis through MRI or ultrasonogram and each patient received intra-articular injection of steroid once. After 2~4 weeks, every patient was interviewed via telephone survey and finally 105 patients were included, 54 patients received only oral NSAIDs (NP group) while 51 patients received additional transdermal buprenorphine patch (BP group). Pain and functional visual analog scale (PVAS, FVAS), American Shoulder Elbow Society (ASES) score was checked. Results: Generally, every outcome variables showed improvements in both groups (p<0.001). PVAS score after treatment showed superior result in NP group but it was not significant (p=0.088). In ASES score, NP group had superior result than BP group and it had significant difference. Similarly in FVAS, NP group showed superior result but the data before treatment was significantly different (p=0.028) Conclusion: Transdermal buprenorphine patch didn't show superior treatment result in the patient with frozen state of frozen shoulder which was applied with oral NSAIDs after single intra-articular glenohumeral steroid injection in short-term follow-up.

The theory of landscape architecture applies environmental ethics in order to secure an ecological status. However, environmental ethics that focus on nature conservation excludes landscape architecture as artifacts. In the process, it is hard to identify what landscape architecture insists on as the middle position between humans and nature. Rather, landscape architecture pretends to be an 'agent of nature' and pushes the traditional moral values 'for people.' Therefore, the purpose of this study is to reestablish the anthropocentrism moral position of landscape architecture through critical analysis. Hargrove's weak anthropocentrism' of several environmental ethics branches accepts natural aesthetics(such as landscape architecture) as an ethical virtue. But environmental ethics makes landscape architecture a critical target. For that reason, this study looked into critical contents and objects that in a position to moral, aesthetic and landscape architecture. Critical details are as follows: First, nature is an absolute as an aesthetic and moral value, but landscape architecture is an imitation and takes a relaxed attitude about nature. Second, nature is full of aesthetic substance because it is self-creative, but landscape architecture is designed nature covered human flaws through imagination. Third, environmental management granting techniques in nature generate a moral nihilism. As an argument, environmental ethics overlooked the moral practices of landscape architecture beyond nature another moral aspect of creation and the imagination-and moral aspects of environmental management as 'care' because they rule out 'moral autonomy' and simplify what is considered 'good.' As a result, conservation cannot be the only virtue why the problem of nature in reality cannot be separated from human life. The moral position of landscape architecture based on a 'good life' is more appropriate under anthropocentrism than as a middle position.

Studies on Pathogenicity of Nosema bombycis Naegeli are summarized as follows: 1. The mortality of the parents, Jam 103 and Jam 104, is remarkbly higher than that of the hybrid, Jam 103$\times$Jam 104, whereas there is no difference in the mortality between the parents. 3. In the mortality of the pathogen-concentration, it is increased in order of the following concentrations inoculated, 10$^{8}$ , 10$^{7}$ , 10$^{8}$ and 10$^{5}$ /ml. 3. In the mortality of each instar, it is high in order of 5th, 4th, 3rd, and 2nd instar. 4. In the interaction between the mortalities of the varieties and the concentrations, 1) The mortality shows no differences between the parents and the hybrid in the high concentration of 10$^{8}$ /ml. 2) The mortality of the hybrid is lower than that of the parents in the low concentration of 10$^{5}$ /ml, whereas no difference is found between the parents. 3) The interaction appears at the same level in the middle concentration of 10$^{6}$ /ml to the parents and of 10$^{7}$ /ml to the hybrid. 5. It was pointed out that active immunity depends upon the volume of antigen injection, immunizing period, and injection intervals. In this experiment, it is noticed that the optimum volume of injection is above 20ml and D is the best one of the four treatment (A.B.C.D.). 6. The immune sera indicate such a 12,800 high titer in the indirect method can be obtained from the D immunizing method. Silkworm tissues and N. bombycis spores show self-fluorescence, but it is able to distinguish it from the F.I.T.C. by using the U.V. filter. 7. The midgut epithelium is examined to be the first site of the tissues which are penetrated into and multiplied by the inoculation of the pathogen per os.

The Medical law stipulates regulations about the physician's duty to inform to contribute to patient's self-determination. This law was most recently revised on December 20, 2016, and came into effect on June 21, 2017. There has been much controversy about this, and it has been questioned whether or not it will be effective for physicians to comply with the duty to inform. Therefore, this study investigated perceptions of physicians of whether they observed the duty to inform and their legal judgment about that duty, and analyzed how the revision of the medical law may have affected the legal cognition of physician's duty to inform. This study was conducted through an online questionnaire survey involving 109 physicians over 2 weeks from March 29 to April 12, 2018, and 108 of the collected data were used for analysis. The questionnaire was developed by revising and supplementing the previous research (Lee, 2004). It consisted of 41 items, including 26 items related to the experience of and legal judgment about the duty to inform, 6 items related to awareness of revised medical law, and 9 items on general characteristics. The data were analyzed using SAS 9.4 program and descriptive statistics, Chi-square test, Fisher's exact test and Binary logistic regression were performed. The results are as follows. • Out of eight situations, the median number of situations that did not fulfill the duty to inform was 5 (IQR, 4-6). In addition, 12 respondents (11%) answered that they did not fulfill the duty to inform in all eight cases, while only one (1%) responded that he/she performed explanation obligations in all cases. • The median number of the legal judgment score on the duty to inform was 8 out of 13 (IQR, 7-9), and the scores ranged from a minimum of 4 (4 respondents) to a maximum of 11 (3 respondents). • More than half of the respondents (n=26, 52%) were unaware of the revision of the medical law, 27 (25%) were aware of the fact that the medical law had been revised, 20(18%) had a rough knowledge of the contents of the law, and only 5(5%) said they knew the contents of the law in detail. The level of awareness of the revised medical law was statistically significant difference according to respondents' sex (p<.49), age (p<.0001), career (p<.0001), working type (p<.024), and department (p<.049). • There was no statistically significant relationship between the level of awareness of the revised medical law and the level of legal judgment on the duty to inform. These results suggest that efforts to improve the implementation and cognition of physician's duty to inform are needed, and it is difficult to expect a direct positive effect from the legal regulations per se. Considering the distinct characteristics of medical institutions and hierarchical organizational culture of physicians, it is necessary to develop a credible guideline on the duty to inform within the medical system, and to strengthen the education of physicians about their duty to inform and its purpose.

Analysis of the aeromagnetic data aquired by US Navy in the year 1969 permits us to predict a new sedimentary basin, Heugsan Basin, south of the known Gunsan Basin in Block Ⅱ. The basin appears to consist of three sub-basins trending NNW-SSE. The results of our analysis provide not only an independent assessment of the Gunsan Basin, but also new important information on the tectonic origin and mechanism for the two basins as well as for the entire region. The basin forming tectonic style is interpreted as rhombochasm associated with double overstepped left-lateral wrench faults. From the magnetic evidence, a few NE-SW trending major onshore faults are extended to the study area. We also interpreted the nature of the faults to be left-lateral wrenches. This new gross structural style is consistent with the results of recent Yeongdong Basin analysis by Lee. The senses of fault movement are also supported by the paleomagnetic evidence that the Philippine Sea had experienced an 80-degree clockwise rotation since the Eocene. Based on a 2 $\frac{1}{2}$ model study the probable maximum thickness of the sediments in the Gunsan Basin is approximately 7500 meters. We believe that the new Heugsan Basin was left unidentified because a high velocity layer may be overlying the basin. Because the overall structural configuration of the Heugsan Basin appears to be favorable for hydrocarbon accumulation, a detailed airborne magnetic survey is recommended in the area in order to verify the magnetic expression of this thick basin. A detailed subsequent marine gravity survey is also recommended in order to delineate the sedimentary section and to acquire supplemental data to the magnetic method only if an overlying high velocity layer is confirmed. Otherwise a high energy source seismic survey may be more effective.

The present study investigated whether leukemia-maintaining cells reside in a differentiation-resistant fraction using a megakaryocytic differentiation model of K562 cells. Treatment with phorbol-12-myristate-13-acetate (PMA) significantly inhibited the colony-forming efficiency of the K562 cells. At a PMA concentration of 1 nM or higher, colony was not formed, but approximately 40% of K562 cells still survived in soft agar. Approximately 70% of colony-forming cells that were isolated following the removal of PMA after exposure to the agent were differentiated after treatment with 10 nM PMA for 3 days. The differentiation rate of the colony-forming cells was gradually increased and reached about 90% 6 weeks after colony isolation, which was comparable to the level of a PMA-treated K562 control. Meanwhile, imatinib-resistant variants from the K562 cells, including K562/R1, K562/R2, and K562/R3 cells, did not show any colony-forming activity, and most imatinib-resistant variants were CD44 positive. After 4 months of culture in drug-free medium, the surface level of CD44 was decreased in comparison with primary imatinib-resistant variants, and a few colonies were formed from K562/R3 cells. In these cells, Bcr-Abl, which was lost in the imatinib-resistant variants, was re-expressed, and the original phenotypes of the K562 cells were partially recovered. These results suggest that leukemia-maintaining cells might reside in a differentiation-resistant population. Differentiation therapy to eliminate leukemia-maintaining cells could be a successful treatment for leukemia if the leukemia-maintaining cells were exposed to a differentiation inducer for a long time and at a high dose.

The purpose of this study was to investigate the level of knowledge, health belief and sick role behavior, and the influencing factors on them among the patients with coronary artery disease. The study subjects were 168 patients diagnosed as having coronary artery disease at a university hospital during the period from July 1st, to August 31th, 2010. As a results, Based on the mean scores of knowledge about coronary artery disease according to the general characteristics, they were significantly higher in males than in females(p=0.033). The mean scores of health belief were significantly higher according to age decrease(p=0.043). The mean scores of sick role behaviors were significantly higher in females than in males(p=0.006), with their increasing tendency in the age range from 40's to 60's and decreasing tendency in the age over 70's(p=0.015), the group with religion were significantly higher than the one without(p=0.050). In terms of the mean scores of knowledge and sick role behaviors about coronary artery disease according to the related characteristics, there was a significant difference with the time period elapsed after diagnosed as coronary artery disease, frequency of admissions, perception about the disease, information gathering through mass com. but in terms of those of health belief, there was a not significant difference in all the variables. The significantly influencing factors on degree of knowledge by multivariate regression analysis included degree of perception about a disease, scores of sick role behavior, presence of coronary artery diseases in a family or friends, and the time period elapsed after diagnosed as having coronary artery disease. Those on health belief included age and scores of sick role behavior, and those on sick role behaviors included score of knowledge, perception about a disease, age, BMI, and religion. The results showed a significant difference with their general characteristics or coronary artery disease-related factors.

Purpose : The majority of PCL deficient knees have some intact remnant PCL bundles. In these cases, the remnant PCL bundles were removed fur easy passage of graft(especially in bone-patellar tendon-bone graft). The purpose of study is to report the results of PCL reconstruction by posterior transseptal portal technique and by preserving the remnant posterior cruciate ligament bundles. Materials & Methods : From November 1993 to June 1999, 44 arthroscopic posterior cruciate ligament reconstructions have been performed by one surgeon. We studied 37 knees those were followed up over 1 year among them. The mean age($14\~56$ years) was 31.8 years. The average follow-up period was 17.8 months($12\~61$ months). The graft materials were 29 double-loop hamstring autografts, 4 double-loop hamstring allografts and 4 Achilles tendon-bone allograft. Results : There are significant improvement of the preoperative subjective symptoms. The last follow-up shows that the average Lysholm knee score was markedly improved from 59.8 pre-operation to 89.2 post-operation and the average KT 2000 side difference was decreased from 11.1mm pre-operation to 2.3 mm post-operation. Follow-up MRI showed that the graft was healed with remnant posterior cruciate ligament bundles as one ligament. Conclusion : The posterior trans-septal portal makes it possible to locate the exact tibial tunnel. The arthroscopic PCL reconstruction preserving the remnant of original PCL bundles seems to provide the good result.

Purpose: To evaluate the clinical and radiologic results of the arthroscopic rotator cuff repair for partial articular surface tendon avulsion lesion. Materials and Methods: Twelve patients with symptomatic, partial articular surface tendon avulsion underwent arthroscopic rotator cuff repair between Mar. 2006 and Sep. 2008. The mean follow-up period was 18.3 months(12~36 months), and the mean age at the time of surgery was 46.9-year-old(19~64 years). Three cases had underwent rotator cuff repair after conversion to full-thickness tear and nine cases had transtendon repair with preserving bursal side cuff. Results: The mean VAS during motion was 6.2 before treatment and 2.0 at final follow-up (p<0.001). The passive forward flexion improved from $163.3^{\circ}$ preoperatively to $169.8^{\circ}$ postoperatively (p=0.038). The mean UCLA score improved from 18.4 preoperatively to 30.1 with 2 excellent, 8 good and 2 fair results at final follow-up. The mean KSS improved from 61.8 preoperatively to 76.8 at final follow-up. By examining the postoperative MR images of 5 patients, complete healing was observed in all of them. Conclusion: Arthroscopic rotator cuff repair may be an effective procedure for partial articular surface tendon avulsion in pain relief and improvement of the range of motion. If the remaining bursal side cuff fibers are intact, transtendon repair procedure with preserving the intact bursal layer of the tendon can be considered. If the remaining bursal side cuff fibers are friable or little, completion from partial-thickness to full-thickness tears with subsequent cuff repair can be considered.

The purpose of this study was to examine the job-related characteristics of dental hygienists affecting their job satisfaction and turnover possibility. The subjects in this study were 297 dental hygienists who worked in dental hospitals and clinics in the metropolitan area. The dental hygienists who worked for three to less than five years, who were unmarried and who didn't benefit from any incentive systems expressed a greater satisfaction, and those who were married, whose workplaces were established jointly with other dental institutions in the form of a network and whose workplaces offered incentives were more likely to change their employment. As for influential factors for job satisfaction and turnover possibility, the respondents whose workplaces were established jointly with other dental institutions were less satisfied, and a larger number of patients and better communication led to higher satisfaction. Those who worked in general hospitals were more likely to change their employment, and better welfare benefits, more appropriate length of working hours and a larger number of patients led to lower turnover responsibility. The findings of the study ascertained that working environments were one of the factors to impact on job satisfaction and turnover possibility, and both of hospitals and dental hygienists should make an effort to improve working environments.
