Objective : To evaluate the role of Gamma Knife radiosurgery in essential and tumor-related(secondary) trigeminal neuralgia, outcomes of radiosurgery and microsurgery were compared each other. Methods : Five patients with essential trigeminal neuralgia underwent stereotactic radiosurgical treatment with Leksell Gamma Knife and twenty five patients were treated with microsurgery during the same period(1994. 1-1997. 6). A 4-mm collimator was used and REZ or proximal portion of trigeminal nerve was targeted with maximal dose of 60-72Gy. The mean follow-up after radiosurgery was 39.4 months and that after microsurgery was 47.9 months. Results : At the last follow-up, four patients(80%) had excellent(pain free) or good(50-90% pain relief) outcomes, one(20%) had poor control after radiosurgical treatment. Twenty-three patients(92%) had excellent or good outcomes and two(8%) had poor results after microsurgery. Postoperative complications occurred in ten(40%) with microsurgery, but there were no complications in patients with Gamma Knife radiosurgery. Six patients with secondary trigeminal neuralgia received radiosurgical treatment directed at their tumors, and three patients were surgically treated. Three of six(50%) patients treated with Gamma Knife had pain relief while two of three patients with surgical treatment showed immediate pain relief. Post-treatment complications were developed in two of six radiosurgical patients and in one of three surgical patients. Conclusion : Gamma Knife stereotactic radiosurgery may be considered as a useful and alternative option for the treatment of essential and secondary trigeminal neuralgia owing to of its safety and less complications. The preliminary results obtained in our series appear encouraging, although the outcome is not so good as that of surgery.

Pneumothorax-either spontaneous or iatrogenic-is commonly encountered in pulmonary medicine. While secondary pneumothorax is caused by an underlying pulmonary disease, the spontaneous type occurs in healthy individuals without obvious cause. The British Thoracic Society (BTS, 2010) and the American College of Chest Physicians (ACCP, 2001) published the guidelines for pneumothorax management. This review compares the diagnostic and management recommendations between the two societies. Patients diagnosed with primary spontaneous pneumothorax (PSP) may be observed without intervention if the pneumothorax is small and there are no symptoms. Oxygen therapy is only discussed in the BTS guidelines. If intervention is needed, BTS recommends a simple aspiration in all spontaneous and some secondary pneumothorax cases, whereas ACCP suggests a chest tube insertion rather than a simple aspiration. BTS and ACCP both recommend surgery for patients with a recurrent pneumothorax and persistent air leak. For patients who decline surgery or are poor surgical candidates, pleurodesis is an alternative recommended by both BTS and ACCP guidelines. Treatment strategies of iatrogenic pneumothorax are very similar to PSP. However, recurrence is not a consideration in iatrogenic pneumothorax.

Objectives: The aim of this study is to verify relationship between suicidal ideation and associated socio-demographic, psychological and behavioral, violence, protective factors among in poor urban area adolescents in Peru. Methods: A cross-sectional survey was conducted in a sample of 981 secondary school adolescents in 2014 collaborating with Korea International Cooperation Agencies (KOICA) Peru office. For statistical analysis, Chi-square test, logistic regression analysis methods were used. Results: 14.0% of male and 37.1% of female were reported having suicidal ideation during the past 12 months. Suicidal ideation experience of male is affected by mother's education level, depression, life satisfaction, sexual intercourse experience, fight experience, insulted experience. Female is affected by depression, life satisfaction, sexual intercourse experience, insulted experience and physical abuse experience. Conclusions: Suicidal ideation experience in poor urban area of Peru is affected by socio-demographic, psychological and behavioral, violence factors. To solve and prevent suicide of adolescents in this kind of area, it is necessary to apply an integrated development program for parents and teachers to participate. For the sustainable preventive program, there is a need to introduce a counseling program, such as psychological counseling to adolescents suicide prevention programs.

Traffic accidents involving agricultural machinery have been decreasing, but mortality is still high due to a lack of safety devices such as seat belts. Furthermore, secondary damage, such as abdominal impalement injury caused by loaded materials, is more likely to occur, and this type of injury leads to a poor prognosis. Impalement with pipes is often more fatal than other penetrating injuries because the diameter of the pipe is usually larger in size than other loaded materials. We report a case of a 72-year-old man with secondary abdominal impalement injury caused by a scaffolding pipe following a traffic accident.

As security management center of financial area, financial ISAC monitors financial corporations and provides security services. Financial ISAC minimizes damage by responding quickly to external attack such as hacking, virus but it is poor at handling internal attack. For the efficient management and stable operation of information source, also to respond jointly to online hacking, the necessity of information sharing system increases day by day in and outside country. This paper proposes financial ISAC that can prevent a secondary damage of leakage information as well as providing security services. The proposed financial ISAC provides new password to financial corporation in which the same ID and password as leakage information are used and in case of financial information leakage it warns customers against phishing etc.

Primary uraninite and secondary uranium minerals such as torbernite, metatorbernite, tyuyamunite, metatyuyamunite, autunite and metaautunite have been identified from various types of uranium ores. Uranium minerals occur as accessory minerals in both the primary and secondary ores. Low·grade uranium ores consist of various kinds of primary and secondary minerals. Major constituent minerals of primary uranium ores are graphite. quartz. Ba-feldspar and sericite/muscovite, and accessories are calcite, chlorite, fluorapatite, barite, diopside, sphene, rutile, biotite, laumontite, heulandite, pyrite, sphalerite and chalcopyrite, and secondary minerals consist of kaolinite, gypsum and goethite. Uraninite grains occur as microscopic very fine-grained anhedral to euhedral disseminated particles in the graphitic matrix, showing well·stratified or zonal distribution of uranium on auto-radiographs of low-grade uranium ores. Some uraninite grains are closely associated with very fine-grained pyrite aggregates, showing an elliptical form parallel to the schistosity. Some uraninite grains include extremely fine-grained pyrite particle. Sphalerite and pyrite are often associated with uraninite in graphite-fluorapatite nodule. The size of uraninite is $2{\mu}m$ to $20{\mu}m$ in diameter. Low-grade uranium ores are classified into 5 types on the basis of geometrical pattern of mineralization. They are massive, banded, nodular, quartz or sulfide veinlet-rich and cavity filling types. Well-developed alternation of uranium-rich and uranium-poor layers, concentric distribution of uranium in graphite-fluorapatite nodule and geopetal fabrics due to the load cast of the nodule suggest that the uranium was originally deposited syngenetically. Uraninite crystals might have been formed from organo-uranium complex during diagenesis and recrystallized by metamorphism. Secondary uranium minerals such as torbernite, tyuyamunite and autunite have been formed by supergene leaching of primary ores and subsequent crystallization in cavities.

This study aimed to analyze the relative effects of parents' child-rearing attitudes and the quality of peer and teacher relationships on poor adolescents' self-resilience and self-esteem. The subjects were 639 1st grade middle school students from the firstly poor, the secondary poor, and the thirdly poor families who participated in the Korea Child Youth Panel Surveys(KCYPS). The data were analyzed with descriptive statistics and hierarchical regressions. The results of this study were as follows. Firstly, the poor adolescents' self-resilience were influenced by the quality of peer relationships, parents' child-rearing attitudes, and the quality of teacher relationships in order and the specific variables enhancing adolescents' self-resilience were communication between adolescents and peers, trust with peers, parents' love, reasonable explanation, supervision, and teacher-adolescents' friendly relationships. Secondly, the poor adolescents' self-esteem were influenced by parents' child-rearing attitudes, the quality of peer relationships, and the quality of teacher relationships in order and the specific variables enhancing adolescents' self-esteem were parents' love, supervision, inconsistency, senses of non-alienation among peers, communication between adolescents and peers, trust with peers, and teacher-adolescents' friendly relationships. Finally, the future directions of education welfare programs targeting poor adolescents were suggested on the basis of the results.

A 6-month-old female Pekingese was euthanized due to poor progrosis after 1 month history of neurologic signs that include depression, ataxia, urination and defecation difficulty. At necropsy, no significant gross abnormalities were noted Histologically, neuronal vacuolation was noted in the brain, primarily cerebellum and occasionally in the brain stem area. Neuronal necrosis and secondary axonal swelling were also observed. Differential diagnoses were able to rule out other diseases which can induce neuronal vacuolation such as lysosomal storage disease, prion infection, and postvaccinal change.

Integration of microbial antagonists with fungicides was tried to control the gray mold caused by Botrytis cinerea on pepper in greenhouse conditions and to reduce fungicide uses. All of the selected bacterial antagonists, Bacillus amyloliquefaciens BL3, Paenibacillus polymyxa BL4, and Pseudomonas putida Cha94, completely inhibited the conidial germination of B. cinerea until 30 days after treatment. However, bacterial colonization of pepper phylloplane was poor in BL4, while the other bacterial isolates and the fungal antagonist Trichoderma harzianum TM colonized well on the phylloplane, maintaining the population density of 104-105 cfu/g until 15 days after microbial treatments. Out of 13 kinds of selected fungicides used for gray mold diseases, polyoxin B and BKF 1995 showed the most discriminatory activity on the fungal growth between B. cinerea and TM. TM grew readily on the media containing those fungicides, while B. cinerea showed poor or no mycelial growth on them. The selected fungicides and antagonists alone reduced incidence of gray mold on pepper, showing disease indices of about 2.4 to 3.0, while its was increased up to 4.2 in the untreated control. Alternate treatments with the antagonists and 2-fold diluted fungicides inhibited the disease incidence as much as the antagonists or fungicides alone, and reduced the secondary inoculum more than the single treatments. This suggests that integration of antagonists and fungicides may be an efficient way to reduce fungicide sprays with reliable control efficacy of the disease. However, there was not much difference in the early and mid-term disease progress among the treatments and the untreated control, probably due to extremely favorable environmental conditions for the disease development in this experiment.
