Purpose: The purpose of this study was to examine what characteristics and qualities of a teacher bring out positive changes in students. In order to this, researcher investigated positive changes of students and PE teacher`s characteristics and qualities that promote students` changes. Method: This study used qualitative complex case study. Participants were 5 PE teachers who participate in community focusing on students` character development, and their 10 students. Non-participant observation and in-depth interview were used. In addition, open questionnaire was administered with 200 students. Collected data were analyzed using inductive thematic analysis. Triangulation, member checks, and peer debriefing were conducted to enhance the trustworthiness of this study. Result: First, character of students have changed in various way. Students internalized 4 virtues of In, Eui, Ye, Gi categorized as most comprehensive range. They made an effort to become those who are filled with love(In), justice(Eui), courtesy(Ye), wisdom(Gi). Second, positive change effects are not based on single dimension but it depends on overall dimensions such as health, wisdom, emotion, morality, and spirituality. Health as qualities of PE teacher is concerned with achieving excellence in sport performance and keeping in good shape. Wisdom is concerned with having knowledge about the methods of PE class and preparing, being well-informed of character education and applying it to PE class, and noticing and managing students` changes in character. Emotion is associated with believing relationship with student important and being contented with students` enjoyment. Morality is concerned with trying to become a whole person a good model. Spirituality is associated with cherishing PE, students, themselves, and god, and pursuing students` development to become a whole person. These characteristics and qualities of PE teachers influenced to students on the whole process such as preparation, execution, and reflection of PE classes. It showed a stronger influence on the students` character changes when PE teachers exert to reflect and compliment themselves. Conclusion: Character development in students is not based on teacher`s content knowledge and instructional techniques. Character of students can be positive only when PE teachers` wholeness involved on the whole. It should reflect to in-service education for PE teachers about students` character. Furthermore we must research more in depth about what types of qualities of teachers give students` change in some types of pathways.

Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

Background: Various primary tumors can cause metastatic skin cancer. Metastatic skin lesion should be distinguished from other skin lesion. Objectives: We studied patients with metastatic skin cancer to find out average age, gender distribution, frequency of primary tumor, time interval between manifestation and primary cancer, and their clinical appearance, location and other metastatic sites. Methods: We reviewed the medical records, clinical photographs and histopathologic records of patients who had been diagnosed with metastatic skin cancer. Results: In the comparison according to clinical records, the mean age at the time of diagnosis was 60.6 years. The ratio of men to women was 1.05:1. The most frequent primary tumors were breast cancer (22.0%), lung cancer (17.0%), head and neck cancer (17%), melanoma (17.0%), gastrointestinal cancer (11%), urologic cancer (11%), and gynecologic cancer (6%). Metastatic skin cancers usually presented as discrete, painless, hard nodules, with sudden onset (88%). Conclusion: Based on the results of this study, it is believed that it is important to recognize the metastatic lesion between various skin lesion such as infections and granulomatous changes of other cause due to drugs and reactive changes.

Background: As the incidence of skin cancer increases, more information and education on skin cancer are needed. Although skin cancer is not rare, most patients are little known about general awareness of skin cancer. Objectives: The purpose of this study is to investigate the post-education effects on skin cancer in our hospital outpaitents and carers. Methods: We reviewed a written questionnaire and patients’ self-checked records including patients’ basic medical information and knowledge of skin cancer protective modalities. Results: In total 340 cases, 215 (63.2%) patients were female and 125 (36.8%) patients were male. 6 people in their teens, 56 people in their 20s and 30s, 156 people in their 40s and 50s, 122 people in their 60s or older. Before education, 142 people said sunlight can cause a skin cancer and 178 did not. After education, 246 people said Yes and 94 people did not. When asked how you wanted to get more information on skin cancer, 104 (30.6%) people said that they were printed handout, 142 (41.8%) were visit to dermatologists, 52 (15.3%) were photos of skin symptoms, and 42 (12.3%) were phone calls. Conclusion: This result showed that people are little known about risk factor of skin cancer such as sunlight and artificial tanning. However, we found that through education, people's perceptions could change. The education on behavior for skin cancer prevention should be continued so that the awareness of the risk of skin cancer can be changed.

Thermogravimetric analysis and pyrolysis experiment were used as studying the effent of conversional level on the thermal degradation of HDPE. The wide conversional range in this work encompassed a change in the degradation mechanism. To accommodate this mechanism change, the data were treated as a pseudo first-order reaction. It was observed that the data conformed to a first-order fit at conversional range of 0.05∼0.98 with an activation energy of 376 kJ/mol. The lower activation energy occurring at lower conversion (0.01∼0.05) is attributed to scission of 'weak links' in macromolecles. The higher activation energy was similar to the carbon-carbon bond dissociation energy and is associated with random scission throughout backbone chain. The lower the conversional level, the more abundant the paraffinic hydrocarbon in product. To what extent this finding are influenced by limitation of terminate reaction of radicals.

Background : Multi-organ failure from sepsis is very lethal disease entity, which is suspected to be caused by activated inflammatory cells. Inflammatory cells activated by endotoxins generate oxidants and cytokines such as TNF-α and IL-6, which in turn stimulate macrophages and neutrophils. Augmented inflammation makes an organ-injury deteriorate into an organ-failure, which may progress to multi-organ failure. This study is designed to evaluate the therapeutic effects of vitamin-C, a scavenger of oxidants, in sepsis. Methods : Male Sprague-Dawley rats were divided into 3 groups : a control group, a group injected intrapetoneally with LPS(lipopolysaccharide), and a group injected intraperitoneally with LPS and vitamin-C. Each eight rats were sacrified 24 hours and 48 hours after injection, and samples of the blood, the liver and the lung were obtained. Biochemical assays of TNF-α level in the blood and malondialdehyde(MDA)level, catalase activity and nitric oxide synthase(NOS)activity in the liver and the lung tissues were performed. Results : Serum TNF-α level, tissue lipid peroxidation and tissue i-NOS activity were dramatically increased, and tissue catalase activity was exhausted rapidly in sepsis. High dose vitamin-C administration decreased serum TNF-α level, tissue lipid peroxidation and tissue i-NOS induction, and protected against catalase exhaustion. Conclusion : high dose vitamin-C therapy was proved to have definite antioxidant effect in septic condition.

Speckled lentiginous nevus is circumscribed patch of hyperpigmentation with smaller, darker pigmented macules or papules within the patch. The background shows histologic features of lentigo simplex. The speckled areas show junctional or compound nevus. Association of speckled lentiginous nevus with multiple spitz nevi was rarely reported. We report a case of multiple spitz nevi arising in a giant speckled lentiginous nevus. (Korean J Dermatol 2003;41(11) : 1568-1570)
