Purpose : Methicillin Resistant-Coagulase Negative Staphylococcus(MR-CNS) infection has become an increasingly important cause of morbidity in NICU infants. We investigated the c linical characteristics of MR-CNS sepsis. Methods : This study included 40 neonates with MR-CNS sepsis who were admitted to the neonatal intensive care unit of Kangnam Sacred Heart Hospital, Hallym University from January 1998 to July 2002. MR-CNS sepsis was defined as MR-CNS recovery from blood with clinical symptoms and signs of infection. Retrospective analyses of the medical records of patients with MR-CNS sepsis were performed. The analyses included demographic findings, clinical features, hospital courses, risk factors for infection including invasive procedures and mortality. Results : From 1998 to 2002, there were 40 cases of MR-CNS sepsis, comprising 17.7% of late onset infections in NICU of Kangnam Sacred Heart Hospital. The male/female ratio was 1.5 : 1. The mean gestational age of infected babies was $32.4{\pm}4.3$ weeks at birth. And the first positive MR-CNS culture was done in the day $10.6{\pm}9.3$ after birth. Clinical symptoms such as fever, dyspnea, cyanosis, grunting, bradycardia, vomiting and diarrhea were frequent in MR-CNS. Mechanical ventilation was applied in 12 cases and catheter was inserted in 11 cases. The mortality(12.5%) directly attributable to MR-CNS sepsis was similar to other late onset infections. Conclusion : MR-CNS is a pathogen responsible for most late onset and nosocomial infections. And it will be life-threatening in high-risk neonate. Awareness of increasing infections due to MR-CNS in NICU is important not only for infection control but also placing a great limit in use of antibiotics and invasive procedures, especially in premature infants.

This study has been historically reviewed the clothing and textiles education through references. The clothing and textiles education had been informally offered as a part of household skill, skill of daily life and home skill before the law of school education was established. Therefore, we have reviewed the changes in the clothing and textiles education by separating the prior period between the end of the old Korea and the liberation in 1945, from the later period from the liberation up to now. And also contents of clothing and textiles education between before and after the revision of the 7th curriculum were compared and analyzed. The clothing and textiles education had put emphasis on sewing, handicraft and household during the prior period from the end of the old Korea to the liberation, but after liberation, it became involved in Home Economics Education. The number of classes and the contents of clothing and textiles education had been increased and deepened from the 1st term to the 5th term of curriculum. In particular, the 4th and 5th term of curriculum became a turning point where home life section was intensified. Even though the number of classes was reduced during the 6th term of curriculum, with increase in target school grades for this education, and Home Economics in the middle school remained an independent subject matter. However, during the 7th term of curriculum, Technology-Home Economics Education in the middle school courses led to losing independent subject name and shrinking its contents. Through the revision in the 7th curriculum, the clothing and textiles education achieved great improvement and progress by gaining balance in distribution of contents among school grades and balance between theory and practice. However it still remains as an issue to be more studied and resolved how well the contents are matched with the interests and attention of students. We need to consider and reflect request of students under learner-centered curriculum. Considering enormous changes in the environment surrounding the clothing and textiles education, it is crystal clear that the gap between existing contents of education and teaching methods and our real life will be widened. Because students' perceptions of value have been diversified, it is our task to develop better contents and learning system in order to help students have interests, attention and desire in clothing and textiles life in line with social needs for desirable clothing and textiles education.

1. Background : Sasang Constitutional Medicine divides mankind into Taeyangin(太陽人), Taeumin(太陰人), Soyangin(少陽人) and Soeumin(少陰人) according to appearance, moral nature and characteristic of constitutional symptoms, and it is a medical science to study about different treatment for each constitution. In Sasang Constitutional Medicine, diagnosis of constitution was so important that we had the necessity of studying constitutional diagnostic method which had presented wholly and intuitively in Dongyi Soose Bowon(東醫壽世保元) with objective and analytic thinking. There were several attempts to classify Sasang Constitutional Types through morphological investigation of each parts of body. The one of them was to use measuring the body. In this study, we purposed to make clear whether the analysis of fingerprints and palm, one of the physical anthropologic methods would be helpful to classify Sasang Constitution. 2. Method : After practicing Questionnaire I and QSCC(Questionnaire of Sasang Constitution) II from 347 healthy Korean adults(242 males and 106 females), we analyzed fingerprints and palm prints of 208 people(142 males and 66 females) who were classified same constitution from two questionnaires. We analyzed the types of fingerprints according to the number of triradius and counted the number of dermal ridges from fingerprint center to triradius. We found triradius in the lower part of each finger and analyzed the courses of dermal ridges and counted the number of dermal ridges between each triradius. We mesured angle atd, and then researched relationship between fingerprints, palm prints and Sasang Constitution. 3. Result and Conclusion : The results of Sasang Constitution analysis of 208 Korean adults showed 76 Taeumin(36.5%), 81 Soeumin(39.0%) and 51 Soyangin(24.5%). The analytic results of fingerprints and palm prints are as follows : The types of fingerprints were helpful to sort Taeumin and the types of palm prints were helpful to sort Soyangin and Soeumin especially. In addition, the number of dermal ridges in fingerprints and palm prints were helpful to sort Soyangin. Fingerprints and palm prints have characteristic in each constitutions, so the investigation of fingerprints and palm prints seems to helpful to classify Sasang Constitution. We are planning to report fingerprints and palm prints of more subjects.

Breast conserving surgery and irradiation is now accepted as preferable treatment method for the patients with stage I and II breast cancer. Our institution activated team approach for breast conservation in 1991 and treated one hundred and fourty patients during the next three years. Purpose : To present our early experience with eligibility criteria, treatment techniques, and the morbidities of primary radiotherapy. Materials and Methods: Sixty four patients with early stage breast cancer who received breast conserving treatment between January 1991 and December 1992 were evaluated. All patients received partial mastectomy(wide excision to quadrantectomy) and axillary node dissection followed by radiotherapy. Total dose of 4500-5040 cGy in 5-5 1/2 weeks was given to entire involved breast and boost dose of 1000-2000 cGy in 1-2 weeks was given to the primary tumor site. Linac 4 MV X-ray was used for breast irradiation and electron beam was used for boost. Thirty five Patients received chemotherapy before or after radiotherapy. Patients characteristics, treatment techniques, and treatment related morbidities were analyzed. Results : Age distribution was ranged from 23 to 59 year old with median age of 40. Twenty-seven patients had T1 lesions and 34 patients had T2 lesions. In three patients, pathologic diagnosis was ductal carcinoma in situ. Thirty-seven Patients were N0 and 27 patients were Nl. There were three recurrences, one in the breast and two distant metastases during follow-up period(6-30 months, median 14 months). Only one breast recurrence occured at undetected separate lesion with microcalcifications on initial mammogram. There was no serious side reaction which interrupted treatment courses or severe late complication. Only one symptomatic radiation pneumonitis and one asymptomatic radiation pneumonitis were noted. Conclusions: Conservative surgery and primary radiotherapy for early breast cancer is Proven to be safe and comfortable treatment method without any major complication. Long-term follow up is needed to evaluate our treatment results in terms of loco-regional control rate, survival rate, and cosmetic effect.

Purpose : Hydronephrosis constitutes a great portion of fetal anomalies screened by prenatal sonogram. The present authors made an attempt to access its natural courses through follow up neonatal hydronephrosis diagnosed by prenatal sonogram. Methods : The study was composed of 23 neonates(36 renal units) who were diagnosed with hydronephrosis through prenatal sonogram screening and confirmed 3-7 days after birth with sonographic evaluation at Kyung Hee University Hospital. The neonates were closely monitored for 12-24 months with renal sonogram, diuretic renogram, intravenous pyelography(IVP) and voiding cystoureterography(VCUG). Results : The underlying diseases were composed of 16 cases(44%) of functional abnormalities, 14 cases(39%) of ureteropelvic junction(UPJ) obstruction, three cases(8%) of vesicoureteral reflux (VUR) and on case each of multicystic dysplastic kidney, UPJ obstruction with ureteral stenosis and ureterovesical junction(UVJ) obstruction with VUR. The degree of hydronephrosis was divided into three classes according to its severity. In 30 renal units with UPJ obstruction and functional abnormalities, 26(87%) showed mild hydronephrosis, while four(13%) were moderate. During the follow up period, six cases(20%) showed natural resolution of hydronephrosis, 15 cases(50%) showed improvement while two cases(7%) were aggravated with improvement only after surgery of the underlying disease. The cases which showed natural resolution were all mild hydronephrosis at diagnosis and the cases which underwent surgery due to continuous aggravation were mild one case and moderate one case. Conclusion : Those with cases of mild hydronephrosis show rapid natural improvement. On the other hand, in some cases, follow up monitoring reveal aggravation of the situation, emphasizing the necessity for thorough follow up for a long period of time.

Purpose: There has been increased the number of early gastric cancer and laparoscopy-assisted gastrectomy (LAG), due to early detection through mass screening program. We started the LAG in April 2004 and performed 119 cases of gastric cancer in 2005, so we report a surgical outcome compared with that of open gastrectomy (OG). Materials and Methods: 119 patients underwent LAG in 2005, and for open group, 126 patiens of early gastric cancer were selected sequentially from January 2005 to March 2005. We compared clinicopathologic characteristics, postoperative courses and complications between two groups. Results: There was no significant difference between age, a length of hospital stay, distal resection margin and a number of retrived lymph nodes. The operation time was longer in LAG group (239.2 vs 123.3 mins, P<0.001) and a diet progression was faster in LAG group (first flatus: 3.05 vs 3.70 days, SOW: 2.86 vs 3.22 days, liquid diet: 3.87 vs 4.19 days, soft diet: 4.84 vs 5.26 days, P<0.001). But there was no difference statistically in postoperative discharge date (7.73 vs 8.25 days, P=0.229). The additional requirement of analgesic injection was less frequent in LAG group (2.97 vs 4.92 times, P<0.001). The harvested lymph nodes were similar in both groups (23.9 vs 23.1, P=0.563). A complication rate was lower in LAG group (4.9% vs 9.5%), but there was no statistical significance (P=0.179). There was no mortality in both groups and no conversion to open gastrectomy in the LAG group. Conclusion: LAG can be performed safely and accepted in view of curative procedure in treatment of early gastric cancer. But we need the follow up of long-term period to evaluate the survival rate and recurrence, and a prospective randomized controlled study should be done to establish that LAG will be a standard operation for early gastric cancer.

Objective : Cavitary lesion in pulmonary tuberculosis sometimes makes problems in the course of treatment. Especially, retreatment cases tend to respond poorly to current antituberculosis agents. So, authors tried to render a guideline for clinical approach toward cavitary lesions in pulmonary tuberculosis. Methods : Retrospective analysis of 33 pulmonary tuberculosis patients with cavitary lesions was made. All the patients had got treatment at National Masan Tuberculosis Hospital from Jan. 1995 to Aug. 1995. Results: The ratio between male and female was 10:1. Age distribution was 69.7% in 3rd and 4th decades. The locations of cavitary lesion were 60.6% in right upper lung field and 36.4% in left upper lung field. In the extent of disease, there were 12 cases(36.4%) in moderate advanced and 21 cases in far advanced. Cavitary lesions were closed in 5 eases and remained in 28 eases. In the cases of closed cavity, it was happened within $10.6{\pm}4.72$ months after they took treatment, the size of cavity was $35.5{\pm}17.1$ in long diameter, $27.0{\pm}12.2$ in short diameter and $4.6{\pm}2.1\;mm$ in wall thickness. In the cases of remained cavity, the size of cavity was $31.9{\pm}12.3$ in long diameter, $21.0{\pm}9.8$ in short diameter and $5.04{\pm}2.0\;mm$ in wall thickness. In terms of negative conversion, it took $3.8{\pm}2.17$ months in the case of closed cavity but it was happened within 5 months for only 4 patients in the case of remained cavity. In the point of past medication history, there was none in closed cavities but there were none in 1 case, once in 3 cases, two times in 9 cases and more than three times in 13 cases among remained cavitary lesions. Conclusion : In the retreatment cases of pulmonary tuberculosis with cavitary lesions, they tend to respond poorly to current antituberculosis agents. So, if the lesions are localized, operative intervention may be a proper method as adjunctive treatment.

Background : Pneumocystis carinii pneumonia (PCP) is one of the most common cause of infection in patients with HIV infection. Recently, the incidence of PCP have been increasing in immunocompromised hosts without HIV infection. We compared the clinical characteristics of PCP between HIV infected and non-infected persons. Patients and Methods : We retrospectively reviewed the charts of 25 patients diagnosed as PCP from 1996 to 2002. Age, sex, underlying conditions, use of immunosuppressants, clinical courses, laboratory findings, treatment and prognosis were compared between HIV infected and non-infected persons. Results : Twenty-five patients with PCP were identified. 16 were HIV infected, and 9 were HIV non-infected. The mean age of overall patients was $43.4{\pm}13.2$ years. Underlying conditions in HIV non-infected persons were hematologic malignancy (7 cases), solid organ transplant (1 case), and autoimmune disease (1 case). Seven cases (77.8%) of HIV non-infected persons had a history of steroid use. Mean duration of symptoms was longer in HIV infected persons than in HIV non-infected persons, but it was not statistically significant. PaO2 was lower in HIV infected persons ($61.2{\pm}16.9$ mmHg vs. $65.4{\pm}15.4$), but it was not statistically significant. Chest X ray showed typical ground glass opacity in 12 cases (75%) of HIV infected persons and in 4 cases (44.4%) of HIV non-infected persons. Twelve cases (75%) of HIV infected persons were treated with steroid, as were 6 cases (66.7%) of HIV non-infected persons. Ventilator care was needed in 6 cases (37.5%) of HIV infected persons and in 2 cases (22.2%) of HIV non-infected persons. Mortality of HIV infected persons was 50%, and that of HIV non-infected persons was 11.1%. Conclusions : PCP showed some different clinical characteristics between HIV infected and non-infected persons. Prospective studies regarding the risk factors of PCP, prophylaxis, treatment and prognosis in HIV infected and non-infected persons are warranted.

Purpose: With the purpose of educating and producing outstanding paramedics by enhancing their competencies, this study aimed to make policy suggestions to re-establish the education system and improve the national examination and the certification scheme. Methods: This study used focus group interviews and questionnaires to collect data. Totally, there were 277 subjects, including experts from the education and field. Data were collected from September 9 to 20, 2016, and analyzed using SPSS 22.0. Results: To strengthen the curriculum of paramedics, this study suggested 27 courses with 94 credits as the standardized curriculum and derived 9 core competencies of paramedics. For the national examination, this study suggested consolidating written test subjects, adding scenario questions to practical tests, and applying critical criteria to simple practical tests that performs a procedure, grading these tests on a pass/fail basis. In addition, this study suggested converting certification into license, reflecting paramedics' healthcare job characteristics. Conclusion: The quality of emergency medical services in Korea will improve when those with core competencies that originated from the standardized curriculum based on the results of this study acquire their certification through the national test scheme, and the certification management system creates a virtuous cycle to further enhance paramedics' professionalism.

Purpose : $Henoch-Sch\"{o}nlein$ purpura(HSP) is a systemic vasculitis that involves multiple organs, especially the kidney, which is the most important organ in determining the prognosis of the disease. The morbidity of HSP nephritis in adults is low and there have been little research done on its clinical course so far. Therefore, we have compared the clinical course of HSP nephritis in children and adults in Korea. Methods : We retrospectively analyzed 81 cases of HSP nephritis in children younger than 15 years of age, and 25 cases of adults older than 15 years of age who were admitted to Yonsei University Medical College Severance Hospital from Jan. 1986 to May 2003. Results : The male to female ratio was 1.5 : 1 in children and 1.3 : 1 in adults. The incidence of HSP nephritis for both age groups was found to be increased during the autumn and winter. Infection was the predisposing factor in 39 cases(48.1%) of children, 16 cases(64.0%) of adults, and drugs were the predisposing factor in 8 cases(9.9%) of children and 4 cases (16.0%) of adults. All patients initially presented with microscopic hematuria. Thirteen cases (16.0%) of children and 7 cases(28.0%) of adults initially showed proteinuria of nephrotic range. Thirty four cases(42.0%) of children and 4 cases(16.0%) of adults showed normal urinalysis after treatment. Asymptomatic urinary abnormalities were found in 41 cases(50.6%) of children and 18 cases(72.0%) of adults. Complications such as nephrotic syndrome and hypertension were found in 3 cases(3.7%) of children and 2 cases(8.0%) of adults. Three children(3.7%) and 1(4.0%) adult required dialysis or renal transplantation. Follow-up renal biopsies were performed on 21 children, of whom 10 cases(47.6%) did not show any histologic change, 9 cases(42.9%) showed low grade changes, and 2 cases(9.5%) showed high grade changes. Prognosis was gloomy when proteinuria of nephrotic range and high grade of abnormal histology were present at diagnosis, and there was no significant difference between the two groups(P<0.05) Conclusion : This study showed that there was no difference in terms of the clinical features and courses between the children and adults with HSP nephritis. Proteinuria of nephrotic range and the severity of abnormal histologic changes at diagnosis were found to be associated with a bad prognosis, therefore we recommend that patients with these features require long term follow-up and management.
