Pelvic actinomycosis is an infrequent chronic suppurative granulomatous disease, caused by a gram-positive bands Actinomyces israelii. It is often reported as a complicated case of an intrauterine device (IUD). Ureteral obstruction and subsequent hydronephrosis are rare complications of pelvic inflammatory disease. Sometimes pelvic actinomyosis is simulating ovarian malignancy. We report a case combined with hydronephrosis, multiple pelvic lymph nodes enlargements and elevated CA 125 as complications of pelvic actinomycosis.

This study set out to collect and analyze data on the games of high school players at 2017 Nationwide Championship and 2017 Korea Junior Taekwondo Federation Championships for the Presidential title, compare and analyze effective blows in Taekwondo matches between high school players by the weight divisions and also the successful scoring rate of effective blows, and provide players and their coaches in the field with basic data to develop techniques and improve performance. Collected data were encoded with the Excel program according to the goals. The encoded data were put to the chi-square test to test the success and failure percentage of kicks in terms of homogeneity according to the gender and weight division. All the data were analyzed with the IBM SPSS 23.0 program. The findings were as follows: first, the study examined differences in the distribution of attack success and failure according to the weight divisions among the male high school players and found no significant differences in the head and significant difference the body(p<.001). The study also examined differences in the distribution of attack success and failure according to the weight divisions among the female high school players and found no significant differences in the head and significant differences in the body(p<.001).

The purpose of this research is to analyze the major patterns and elements of win / lose by collecting and analyzing high school competition data in the 2017 middle and high school Taekwondo Federation presidential competition, and to provide Taekwondo players and coaches with reference materials for training and competitions based on more objective data. The data of Taekwondo competition used in this study were generated by decision tree model using data mining technique to find out factors and patterns related to win / loss. Decision trees were analyzed using SPSS clementine 11.1. The results were follow as: 1. The major factors and pattern of victory in Taekwondo competition were one pattern by face(3 points) and body(2 points). In other words, it is seen that winning rate is changed by acquiring score(2 points) and face(3 points), which are relatively easy to connect with score rather than body(3 points) or face(4 points). 2. Factors and patterns related to the defeat of Taekwondo games were also one pattern due to factors such as face(3 points) and body(2 points). This is because it allows more points for the body(2 points) and face(3 points), which are relatively easy to score, but it also can not score and can lead to a change in the defeat rate. 3. In the validity of the decision tree analysis used in this study, the hit rate for victory was 96% and the hit rate for defeat was 79.3%. This can be said to have yielded reasonable predictions.

The rental apartments serve as a fundamental part of national assets and hold common properties in terms of its facility modes compared to apartments for public sale. Thus, it is anticipated that rental apartments will become the subject of increased focus in the research field of maintenance system currently administered in Korea. Although, miniscule units of application have been developed in addition to increased necessity for computerized system establishment in researches on rental apartments, the standardized methodology to promote such system establishment as a common task has not been suggested as yet. As the result of this study, the maintenance process or rental apartments have been suggested. The TO-BE model, which is to contribute towards standardizing the process, activities to be performed and how information is to be exchanged among such activities, has been suggested in the form of IDEF0 model. The achievement in research of maintenance is to develop process model which could be explained about structures and standards of maintenance in rental apartments. The five serial processes of model are the following : 1. Establishment of basic information on maintenance (A1) 2. Understanding targets for maintenance (A2) 3. Diagnosis on targets for maintenance (A3) 4. Maintenance planning (A4) 5. Execution of maintenance (A5)

This study set out to collect and analyze data on the games of middle school players at 2017 Nationwide Championships and 2017 Korea Junior Taekwondo Federation Championships for the Presidential title, compare and analyze effective blows in Taekwondo games between middle school players by the weight divisions and also the successful scoring rate of effective blows, and provide players and their coaches in the field with basic data to develop techniques and improve performance. Collected data were encoded with the Excel program according to the goals. The encoded data were put to the chi-square test to test the success and failure percentage of kicks in terms of homogeneity according to the gender and weight division. All the data were analyzed with the IBM SPSS 23.0 program. The findings were as follows: first, the study examined differences in the distribution of attack success and failure according to the weight divisions among the male middle school players and found significant differences in the head(p<.05) and the body(p<.001). The study also examined differences in the distribution of attack success and failure according to the weight divisions among the female middle school players and found no significant differences in the head and significant differences in the body(p<.05).

Many alternatives to 1,1,1 TCE (1,1,1 trichloroethane) mainly used as cleaning solvent for metal parts are developed and commercialized because the solvent is scheduled to phaseout after 1996. Considering there are many kinds of parts and contaminants in metal cleaning, it is essential to investigating the characteristics and performance of the alternatives prior to use. For the contaminant of a cutting oil, Actrel 1047L and Solena vda which are the commercially available and promising alternatives were experimented at the same cleaning condition of 1,1,1 TCE to check the cleaning performance. The experimental results showed that the removal efficiency of 1,1,1 TCE was the lowest at the dipping cleaning condition, but it was better at the ultrasonic condition. Overally, the removal efficiency of Solena vda was better than that of Actrel 1047L for removing the cutting oil used in this experiment. But the small portion of spot was not entirely cleaned out with Solena vda, and its removal efficiency in terms of the number of experiments was worse than that of Actrel 1047L. Also trichloroethylene which is one of the conventional chlorinated solvents showed the smallest change in the removal efficiency.

This research shows the preservation administration framework which is conceptualized by link of development of IT solution for the preservation administration of facilities.<br/> Also, the preservation administration framework to propose is general. That is, it is not subject to restriction of administration formation's scale which apply variety of examined property type or scale of equipment administration project or framework. Framework can act in general policy guide line to execute preservation administration within organization which attend to government official of various property set.<br/> Framework would make a standard of process techniques, process activities, and information and method to interchange each activity. In addition to, the update of knowledge would be possible to establish new logical process about these process and activity and to adjust the integration through new administration process or activity if framework's structure would be soft and substantial.

The synchronous existence of endometrial cancer and cervical cancer is very rare. The reported frequency of concurrent gynecologic neoplasms has ranged from 0.7% to 4.3%, synchronous primary tumors of the female genital tract are relatively rare, comprising only 0.49% to 1.7% of all genital neoplasms. The majority of synchronous multiple primary neoplasm of female reproductive tract are of endometrial and ovarian origin. Multiple primary neoplams involving uterine cervix and endometrium were regarded as rare entity. We experienced a rare case of multiple primary neoplasm involving uterine cervix and endometrium and report with brief review of literatures.
