The purpose of this study was to evaluate the accuracy of CPR skills and the satisfaction of CPR Training targeted for college students. Also, this study made comparative study of nursing students and non-nursing students. The sample consisted of 248 students(132 nursing students, 116 non-nursing students). CPR Training was designed by two components which were a lecture and demonstration by one professor and individual practice 표 instructors. As tool of measurement estimation satisfaction of CPR Training questionnaires were developed based on educated contents. The accuracy of CPR skills were checked by SkillReporter CPR training manikin. Collected data were computerized and analyzed by SPSS-WIN program. The results were as follows : 1. The skills of CPR were cardiac compression 92.79 times/min, correct cardiac compression rate 90.85%, ventilation 9.93 times/min. correct ventilation rate 79.34%. 2. The mean of the accuracy of CPR skills were 2.94(SD .87). 3. When errors were analyzed, the highest item was stomach distension(51.2%) of ventilation skills and too little(70.6%) of cardiac compression skills. 4. The mean of the satisfaction of CPR training were 2.87(SD .17), the highest item of the satisfaction of CPR Training was practice. 5. We found significant statistical differences based on the accuracy and the error, non-nursing students were high in correct cardiac compression per minute(t=3.615, p=0...) and ventilation too much(t=4.292, p=.000), nursing students were high in correct ventilation rate(t=-3.885, p=.000) and cardiac compression too shallow) t=-2.842, p=.005).

자연 현상에서 일어나는 변화의 표현은 그 현상에 관련된 물체들의 매개변수 (힘, 속도, 위치, 압력 등)의 값에 의해 나타나진다. 그러나 자연 법칙하에 움직이는 것이나 어떠한 목적으로 만든 동적인 시스템들의 작동을 추론하는 데에 꼭 수학적 방정식과 같은 양적 묘사가 필요하지 않다. 오히려 상황의 전환 과정을 변수의 비례관계나 영향관계로 나타내는 질적 묘사가 시스템의 작동을 추론하고 이해하는데에 일차적인 도움을 준다. 본 논문에서는 질적 추론을 위해 필요한 시스템 구성 요소에 대하여 연구하고 그 구성 요소들이 시스템 동작의 인과관계를 구성해 나가는데 어떤 역할을 하는지 설명하였다.

Mannitol, a hexahydroxy chemically related to mannose, is a non-electrolytic, osmotic agent, It has been known that mannitol may cause serious life-threatening situation if administered in a patient with renal problem. Recently, it has been published that mannitol itself may be nephrotoxic in a patient without preexisting nephrologic disorders. We experienced a case of acute oliguric renal failure caused by long use of mannitol in order to reduce intracranial pressure and cerebral edema after operation of left posterior communicating aneurysm, and reported with recent literature review.

Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

본 연구에서는 두충나무, 황벽나무 등을 포함하는 수목추출물의 소재특성을 시험하여 화장품 및 피부질환 치료소재로서의 응용 가능성을 조사하였다. 수목추출물의 항산화력은 DPPH 자유라디칼 소거법으로 측정되었으며 저농도에서는 항산화력이 낮았으나, 1,000 ug/ml의 고농도에서는 우수한 항산화제인 비타민 C와 유사하였다. 항균력은 원판확산법으로 측정되었으며, 수목추출물은 피부상재균인 Staphylococcus epidermidis에 대해서는 낮은 항균력을 보이지만, 여드름 유발균인 Propionibacterium acne에 대해서는 높은 항균력을 보여주는 선택성 항균력이 있어, 여드름소재로서 매우 우수한 특성을 나타내었다. 무모생쥐를 이용한 항아토피 시험결과, 수목추출물은 DNCB에 의해 유도된 피부염증을 14일 째 거의 정상상태로 회복시켰으며, 피부내 항체인 IgE의 농도도 대조군에 비해 16% 낮추어주어 항아토피 효과가 우수한 것으로 나타났다. 따라서 수목추출물은 항여드름효과 및 항아토피 효과가 뛰어나서 화장품 혹은 피부질환치료소재로서 응용 가능성이 매우 높음을 알 수 있었다. In this study, plant extracts including Eucommia ulmoides Oliv, and Phellodendron amurense were studied to test possible application for cosmetics and skin related medicine. Anti-oxidation effect of plant extracts was measured by DPPH free radical scavenging activity and it was insignificant at low concentration, however, it was as good as vitamin C, excellent anti-oxidation agent, at 1,000 ug/ml. Anti-bacterial effect was tested by disc diffusion method, and plant extracts showed mild anti-bacterial effect for normal skin flora, Staphylococcus epidermidis while it indicated strong anti-bacterial effect for acne inducing Propionibacterium acne. Therefore it had powerful potential for anti-acne material because of selectivity. Anti-atopic dermatitis effect was tested by hairless mouse and plant extracts recovered damaged skin to near normal condition after 14 days of treatment. IgE concentration in treated mouse was decreased 16% compared with control. From the research, plant extracts indicated strong anti-acne and anti-atopic dermatitis effect, and showed strong potential for cosmetics and skin related medicine.

Background: Longitudinal melanonychia is characterized by pigmented bands on the nail plate. It caused by deposition of either melanin or other substances, and associated with activation or proliferation of nail matrix melanocytes. Objectives: We aimed to evaluate the histopathological findings of longitudinal melanonychia in Korean single secondary referral center patients. Methods: In our study, 46 patients with longitudinal melanonychia who visited our clinic from January 2012 to December 2018 were included. We retrospectively reviewed the histopathologic findings that confirmed by biopsy in 47 cases of longitudinal melanonychia. Results: Of the 47 affected nail plates, 33 (70.2%) were fingernails, and longitudinal melanonychia was detected most frequently in the left 1st fingernail (25.5%). Nail matrix nevus was most common (28.3%), followed by subungual melanoma (26.1%), and nail apparatus lentigo (21.7%). 13 patients (28.3%) diagnosed with malignancy, including one with basal cell carcinoma, and 76.9% (10/13 patients) showed a positive Hutchinson’s sign were diagnosed with malignancy. There were 4 patients with accompanying nail plate deformation or ulcers, and of these, 2 patients (50%) were diagnosed with malignancy. Conclusion: This study presented variable histopathologic features of longitudinal melanonychia. We should be considering various conditions as well as melanoma, and determine the appropriate management in patients with longitudinal melanonychia.
