PURPOSE: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. METHODS: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. RESULTS: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. CONCLUSION: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

Plant dermatitis can be classified as primary irritant dermatitis, allergic contact dermatitis, phytophotodermatitis and pseudophytophotodermatitis. Among these, allergic contact dermatitis is seen most freguently. It is generally known that dermatitis causing plants have various characteristics depending on the habitat af different plants. Until now we have had great difficulty in finding the causative factors in plant dermatitis in Korea. This is due to the fact that we do not have anr comprehensive reports regarding domestic or imported timbers concerned in contact dermatiti. The purpose of this thesis is to gather the basic materials necessary to discover the cauae of plant contact dermatitis. All kinds of trees, flowers, and grasses in Korea and imported timbers concerned with contact dermatitis were considered in this study. We strove to ascertain whether the species in our country are the same as found in foreign countries or other different speceies are in our country under the sarne genus found in foreign countries. The basis for our study is several Korean plant books as well as interviews with several native botanists. Vie also discussed major families af plants causing or possible causing plant dermatitis in Korea.

The brief report of Zeisler (1922) of a pregnant woman with scattered telangiectasia in a unilateral distribution is perhaps the first recorded case of this syndrome. The syndrome has been described in association with pregnancy, puberty, alcoholisrn and cirrhosis, hormonal therapy and congenital status. The authors observed in a 17-year-old male unilateral telangiectatic lesions over the left C, C, C, Tl and T, dermatomal regions. The lesions developed at first at his puberty on the anterior part of the chest as speckled bright red discoloration. Thereafter, the lesion has been progressed to involve the left upper extremity, sholder, upper middle part of the chest, eventually. Family history was negative and physical, lahoratory and X-ray examination were all negative or within normal limit. No mucous membrane involvement was observed. On histopathologic examination of the skin lesion, thin walled ectatic vessels lined with single layer of endothelial cells were observed in the upper dermis. The lesions were partly dermabrased with favorable result.

Over the past 30 years, there has been an increase in the incidence of multifetal pregna-ncies, primarily because of the introduction of ovarian stimulants for ovulation induction and assisted reproductive technology ( ART ) in infertile patients. It is well established that multifetal pregnancies are associated with an increased frequency of the maternal complications and gre-ater perinatal morbidity and mortyality. The adverse outcome of multifetal pregnancies is dire-ctly proportional to the number of fetuses, primarily as an consequence of prterm delivery. Re-duction in the number of fetuses in multifetal pregnancies has been proposed as a way to impr-ove the perinatal outcome in this situation. Therefore, selective fetal reduction ( SFR ) is sugges-ted as a therapeutic option for continuation of pregnancy with fetuses mature enough to survi-ve. In this paper, we report our infertility clinic experiences with 6 patients who carried mult- ifetal pregnancies including 1 quintuplet, 1 quadruplet, and 4 triplets. from January, 1991 to May, 1996, transabdominal SFR was accomplished by fetal intrathoracic KCl injection at 9~10 weeks of gestation. After the prcedure, 4 patients remained as twin pregnancies, and 2 patients as single pregnancy. There have been 3 sets of twin deliveries and the 2 sets of single delivery. One case was aborted. Two patients were delivered after 37 weeks of gestation, 2 patients were at 35 weeks, and 1 patient at 24 weeks. All babies have been healthy after birth in patients after 35 weeks gestation. There was no fetal anomaly related to the procedure in the 6 cases. We concluded that transabdominal SFR is a rather safe and useful procedure that may improve the outcome of multifetal pregnancies.

Inflammatory pseudotumor, originally described in the lung, is a relatively rare tumor-like lesion that occurs in various organs and tissues. It is usually well demarcated from the surrounding tissue, however it can be unfortunately resected as a malignant tumor. A few inflammtory pseudotumor in the kidney have been reported in English literature, but there have been no reports in Korea. We report a case with inflammatory pseudotumor of the kidney. A 48 year old woman had an intermittent flank pain on the right side. An ultrasonographic study suggested a renal cell carcinoma and a nephrectomy was done. Grossly, there were two separate masses with a well demarcated yellowish appearance, measuring 2.3 cm and 1.3 cm in diameter, respectively. Histologically, they were composed of smooth muscle actin positive spindle cells and a large number of foamy histiocytes, lymphocytes, and plasma cells in the fibrotic backgound.

Cosmetic dermatitis of the eyelids may be caused not only by eye make-up but also by cosmetics used elsewhere and conveyed by the fingers to the eyelids. The thin skin of the eyelid is highly susceptible to contact dermatitis, particularly from cosrnetics. A 28 year old female was reported to have contact dermatitis caused by stearic acid in eye cosmetics. The skin lesiens of this patient showed erythematous, edematous, vesicular ruptions on both the upper and lower eyelids. The patch test results were positive for both cornmercial eyeliner and fluid mascara on the second and fourth day. Many of all the ingredients in the eyeliner and fluid mascara, only stearic acid gave positive result on patch tests.

Disseminated intravascular coagulation (DIC) is a pathological syndrome in which activation of coagulation cascade leads to fibrin clot formation, consumption of platelets and coagulation factors, and secondary fibrinolysis. We report a case of severe postoperative hemorrhagic diathesis due to DIC. A 59-year-old man was scheduled for reduction of tibia fracture and anatrophic nephrolithotomy of staghorn calculi. On the fifth postoperative day, second operation was performed for nephrectomy due to perirenal hematoma. Two days later, third operation was performed for hemostasis because of the continuous bleeding. Coagulation tests showed positive DIC profiles of thrombocytopenia, hypofibrinogenemia, increased fibrin degradation products, and prolonged prothrombin time and thrombin time. The patient recovered uneventfully and discharged on the 59th postoperative day.

The purpose of this study is to explore perception types and to understand the nature of experience of nursing students' clinical education by using the Q methodology. A Q sample was developed through a review of the literature and descriptions about nursing students' experience in clinical practice. Thirty-six statements made up the finalized Q sample. The P sample consisted of 33 third grade nursing students in K university. Q statements were written on separate cards and were given to the 33 subjects to sort according to degree of agreement or disagreement. The Q-sorts by each subject were coded and analysed with the Quanl PC program. A a result, three major perception types, namely, 'alienation of ideal and reality', 'active participation', and 'perception of limitation of ability' were identified. By identifying the nature of the three types, this study suggests efficient strategies for developing clinical educational programs according to the perception types of nursing students. Clinical education would thereby be more valuable.

PURPOSE: This study was conducted to identify correlations in hospital nurses' work environment, emotional labor and happiness index to provide basic resources for nurses' happiness at work. METHODS: Resources were gathered from 291 nurses who agreed to participate. Random sampling of nurses in nine hospitals in G-do was done between July 15 and August 14, 2014. Data were analyzed using chi2 tests, independent t-test, One-way ANOVA, Pearson correlation coefficients and multiple hierarchical regression with SPSS/WIN 18.0. RESULTS: Mean scores (scale of 5) were nurses' work environment, 2.81, emotional labor, 3.24, and happiness index, 2.94. There were significant differences on the happiness index for: age, marriage, children, clinical experience, position, payment, and future work plans and a negative correlation between work environment and emotional labor, emotional labor and happiness index but a positive correlation between happiness index and work environment. Happiness index was influenced by work environment, emotional labor, future work plans. Explanatory power of these variables was 26%. CONCLUSION: Based on the findings of this study, so it is necessary to improve the work environment and reduce the frequency of emotional labor in order to increase the happiness index of hospital nurses.

Problem-based learning(PBL) is defined as a process of acquiring understanding, knowledge, skills and attitudes in the context of an unfamiliar situation, and applying such learning to that situation. PBL is a way of enabling students thinking more efficiently than they can do in the traditional methods of learning. The purpose of this study was to evaluate the results of PBL conducted in Keimyung University College of Medicine in 1999 as a preliminary course. Tutorials of the PBL course were assigned to ten groups during the third and fourth quarter. In total 6 modules were performed. Each PBL tutorial consisted of 3 meetings and 2 hours were assigned to each meeting. The ability of stating and solving problems, the level of knowledge and assignments were scored and graded. The aptitude for PBL course was evaluated by students and tutors in terms of module, tutor, facilities and in total. Students showed moderate achievement(72.96+/-15.96). Regarding the aptitude of PBL course, most tutors and students showed positive responses. Tutors showed more favorable responses in tutor, facilities and in total. After finishing this preliminary PBL course, the authors could find the consensus of continuing PBL course in our school.
