Purpose:The pathophysiology of magnesium, the second highest common compound in humans, is still unclear, especially in preterm babies. We accessed the association between total magnesium (tMg), ionized Mg (iMg), and gestational age (GA) and that between serum magnesium (sMg) and intraventricular hemorrhage (IVH) in preterm babies. Methods:In all, 119 inborn preterm infants admitted between July 2006 and February 2008 were divided into the IVH group (19) and the control group (100) and were prospectively analyzed. TMg, iMg, pH, total calcium (tCa), and ionized Ca (iCa) levels were determined immediately after delivery or within 3 hours after birth, and their correlation with GA were investigated. Results:TMg was not correlated with GA, tCa, iCa, and pH. IMg was correlated with tMg (r=0.288, P=0.002) and iCa (r=0.212, P=0.021); however, it was not correlated with GA and pH. Mean GA and birth weight were significantly lower (P=0.002) and smaller (P=0.030) in the IVH group. Mean sMg was higher in the IVH group ($2.5{\pm}0.9mg/dL$) than in the control group ($2.1{\pm}0.6mg/dL$) (P=0.021). SMg was a risk factor even after logistic regression analysis (OR, 2.798; 95% C.I., 1.265-6.192; P=0.011). Conclusion:In less than 37-week-old preterm babies, tMg and iMg were similar, regardless of GA. High sMg may be a risk factor for IVH in premature babies, regardless of their exposure to antenatal magnesium.

Purpose : Transcatheter closure of atrial septal defects (ASD) is currently established therapy as an alternative to surgery. But rarely, complications are reported in some studies. We report early and intermediate term complications associated with transcatheter closure of atrial septal defects using the Amplatzer septal occluder (ASO). Methods : From June 2003 to May 2006, 64 patients underwent transcatheter closure of secundum ASD or patent foramen ovale using the ASO. The ratio of male to female was 1:2.4, the median age was 17 years (range: 2.6-64 years) and their median weight was 47.5 kg (range: 2.6-64 kg). Results : The median diameter of ASD measured with transthoracic or transesophageal echocardiography was 15 mm (range: 6-28 mm), the median balloon stretched diameter was 18 mm (range: 6.5-34 mm), and the median size of device was 19.5 mm (range: 6-36 mm), was little difference with balloon stretched diameter. There were 10 cases of complications: arrhythmia (2), device malformation (2), aorta to right atrial fistula (1), hemolytic anemia (1), mitral valve encroachment (1), malposition (1), residual shunt (1), and inferior vena cava perforation (1). Conclusion : Transcatheter closure of ASD using ASO is effective and safe therapy. However, significant complications such as aorta to atrial fistula, atrial erosion, or device embolization can happen, so an appropriate selection of patient and device in relevance to size and anatomy of ASD is important for successful closure.

Purpose : Herbal medicine is thought to be widely used by children with epilepsy, but there have been few studies. This study aimed to investigate the perceptions and the actual conditions of usage of herbal medicine by children with epilepsy. Methods : From July to August 2007, three hundred seventy eight questionnaires were completed by parents of epileptic children who visited pediatric neurology clinic of Korea University hospital and Kwangmyung-Sungae hospital. Demographic data and patterns of usage of herbal medicine were investigated. Results : Among 378 patients, sixty five (17.2%) reported using herbal medicine. Major reasons for using herbal medicine were 'to enhance general health' and 'belief that it has fewer side effects'. Majority of respondents did not notify their physician about using herbal medicine because 'they did not need to share this with doctor' and 'they thought their doctor would disapprove'. After taking herbal medicine, 33.3% of patients reported that it did not benefit their seizure but they felt healthier. Usage of herbal medicine was significantly related to number of AEDs (antiepileptic drugs), duration of AED treatment, association with psychosomatic disorders and motivation by other people or by mass media. Conclusion : Considerable numbers of epileptic children were using herbal medicine during treatment with AED and did not inform their physician about usage of it. Physicians should be aware of benefits and harms of herbal medicine and actively intervene in the usage of herbal medicine by epileptic patients.

Borimsa Temple in Jangheung, one of the Goosanseonmoon of Shilla Dynasty, calls for a study in the field of landscape architecture because it has very significant elements in cultural and ecological landscaping aspects. This study examined the changes in landscaping elements of Borimsa Temple since the 17th century in order to newly recognize cultural landscaping value of space composition elements for traditional temple and to verify landscape architectural position. For research method, literatures such as Sajeonggi (事蹟記), Joongchanggi, a surveyed map by Fujishima Gaijiro in 1928 and Joseon Gojeogdobo (朝鮮古蹟圖譜) and modern documents including Borimsa Temple Precision Ground Survey Report and photographic records of National Archives of Korea and provincial governments were examined together with a field survey in order to trace changes in landscape elements such as buildings within the temple site, pond and temple forest. The results are as the following: First, for geographical locations of Borimsa Temple, it is located in an auspicious location and Shipyuknahansang and Cheonbul were placed in a supplementary purpose according to the contents of Bojoseonsatapbi. Compared to Namhwaseonsa Temple in China, it has a similar environmental composition but the fact that buildings were placed on platforms is a distinctive difference. Second, architectural landscape of Borimsa Temple went through the Japanese colonial era and Korean War and still going through changes today. Thus, there shall be some appropriate measures such as to establish an archive of past landscape data. Third, the contents of Borimsa Temple Sajeonggi suggests that the pond of Borimsa Temple had been in a indeterminate form with stones on the outer edge. Its name could have been Yongcheon (湧泉) according to the contents of Joongchanggi. Also, the current landscape, in comparison with past photographs, is a result of changes from surface raise occurred by ground reinforcement within the temple site. Fourth, Jangsaengpyoju (長生標柱) mentioned in Bojoseonsatapbi and Borimsa Temple Sajeonggi was thought to be the dried juniper tree in front of Daewoongbojeon, which can be found in past photographic documents but, it is now assumed to be Seokbihyeong (石碑形) considering the Gukjangsaeng and Hwangjangsaeng of Dogapsa Temple of the similar time period. Moreover, Hongsalmoon mentioned in Joongchanggi was established by King's order after the Manchu war of 1636 in praising of Buddhist monks those who had volunteered to fight for the country. Fifth, it is apparent in Borimsa Temple Joongchanggi that geomancy was a consideration in landscaping process of Borimsa Temple, and the record indicates that pine trees, bo trees and persimmon trees were planted. Sixth, tea tree forest was verified of its historical root that is Seongchailyeo from Unified Shilla through passing down of Jeong Yak-yong's Goojeunggoopo method and relevant documents of Seon Master Choui and Yi Yu-won. Seventh, nutmeg tree forest suggests that nutmegs were used in national ceremonies and for medical uses. The nutmeg tree forest was also verified of its role as Naehwasoorimdae (a forest built to prevent fire from spreading) through aerial photographs and placement of a forest reserve.

The purpose of this study is to understand preliminary education. level of understanding and the degrees of educational requirement for cancer patients on radiotherapy and to present the preliminary data to development of effective and practical patients treatment programs. Based on the abovementioned results of this study. Relationship betweendegrees of knowledge and demand for educational requirement for patients who are undertaking radiotherapy could be varied with different factors such as educational background, ages, regions of treatment, experience of symptoms. In general, patients do not have enough information, on the other hand, have very high demand for educational requirement. Customized education patients by patients would not be possible in reality. However, if we could provide standard for patients and establish systematic sessions during treatment based on this study, more and better patients satisfaction and results of treatments could be achieved.

Junior colleges are higher education institutions that have played a major role in the economic development of Korea by providing the necessary human resources for its industrial development. Recently, however, they have experienced difficulties due to the reduction in the number of students. Therefore, it is time for junior colleges as a representative higher vocational education institution to change their role in this rapidly changing environment, and adopt a survival strategy through mutual cooperation and competition. The purpose of this study was to analyze the current state of the national health universities, to investigate the policy changes adopted by colleges and universities, and to utilize the results as data. This study analyzed the current status of health science colleges nationwide and investigated the policy changes as well as the directions presented to the colleges, in order to use the results as the basic data to promote the diversification of the class periods and degree programs. This study surveyed 636 professors from health sciences departments and industry workers from May 1 to May 30, 2017. 70.7% of the respondents supported the transition of the existing three-year systems of the health science departments to four-year systems. The reason for this is that it is possible to strengthen the field practice and personality education of the students by having a sufficient number of class periods, and to provide them with an equal educational background. The most anticipated effect of the transition to a four-year system is to improve the social status of medical personnel and to improve the educational environment of the colleges/universities. Moreover, the universities, associations of medical personnel and Ministry of Education are expected to play a leading role in the transition to the four-year system. Based on the results of this study, it was concluded that a more systematic and advanced vocational education system for the training of professional healthcare workers is needed in the upcoming fourth Industrial Revolution era. Also, this transition is expected to actively foster the education of advanced health care workers thanks to the diversification of the degree programs through the adjustment of the class periods which can be completed by general university (4-year) graduates.

The clinical practices provide the students with a good opportunity to study the practical experiences in their field through the clinical training education in hospital. Now, in this study, comparing the perceptions of the clinic teachers with those of students at the clinical site. The study was conducted to the students attending universities located in Seoul and who finished the clinical practices in 2013. The questionnaires were distributed to the student and collected from them. The study were conducted to 275 questionnaires with frequency analysis, crosstabs, chi-square test and McNemar test. The major motivation was of the select radiography course was high employment rate(44.0%) and the satisfaction of radiography course was general(53.1%). 51.3% of the study answered 8 weeks current duration of clinical practices is proper. The 3-year course students answered that the period of clinical practices would be proper if it is performed in the winter vacation in their second year in college(47.3%). The 4-year course students answered that the first semester in their third years is proper for clinical practices( 27.7%). The students answered that they felt the lack in their knowledge on the professional field(32.4%) during the clinical practices and some of the practical training is different from the education performed at school(68.4%). Most of answered that they were satisfied with the clinical practices and among them they recognized the importance of the clinical practices ($3.94{\pm}0.89$). After the clinical practices, their desire for getting job as a radiography has changed from 84.1% to 82.9%. The reason why they want the job related to the radiation is because the job is stable (changed from 49.0% to 46.0% after the clinical practice) while the reason why they don't want be a radigrapher because that job is not proper for them (changed from 37.0% to 40.7% after the clinical practice) The effort should be made to enhance the position of radiation professionals through the improved education system to the students, rather giving them education for just employment.

This study is therefore aimed at measuring the surface dose rate and the spatial dose rate in and outside the radionuclide facility in order to ensure safety of the patients, radiation workers and family care-givers in their use of such equipment and to provide a basic framework for further research on radiation protection. The study was conducted at 4 restrooms in and outside the radionuclide facility of a general hospital in Incheon between May 1 and July 31, 2014. During the study period, the spatial contamination dose rate and the surface contamination dose rate before and after radiation use were measured at the 4 places-thyroid therapy room, PET center, gamma camera room, and outpatient department. According to the restroom use survey by hospitals, restrooms in the radionuclide facility were used not only by patients but also by family care-givers and some of radiation workers. The highest cumulative spatial radiation dose rate was 8.86 mSv/hr at camera room restroom, followed by 7.31 mSv/hr at radioactive iodine therapy room restroom, 2.29 mSv/hr at PET center restroom, and 0.26 mSv/hr at outpatient department restroom, respectively. The surface radiation dose rate measured before and after radiation use was the highest at toilets, which are in direct contact with patient's excretion, followed by the center and the entrance of restrooms. Unsealed radioactive sources used in nuclear medicine are relatively safe due to short half lives and low energy. A patient who received those radioactive sources, however, may become a mobile radioactive source and contaminate areas the patient contacts-camera room, sedation room, and restroom-through secretion and excretion. Therefore, patients administered radionuclides should be advised to drink sufficient amounts of water to efficiently minimize radiation exposure to others by reducing the biological half-life, and members of the public-family care-givers, pregnant women, and children-be as far away from the patients until the dose remains below the permitted dose limit.

Bronchogenic cyst is a rare and benign disease. Because of its complication or associated disease, Bronchogenic cyst requires surgical treatment. Recently, with the development of diagnostic methods, its incidence has increased. So we reviewed our results from the past 30 years. Material and Method: We reviewed 27 cases surgically treated from March 1971 to March 2003. This investigation is designed to illustrate the peak age incidence, sex ratio, symptoms, anatomic location, radiologic imagings, associated diseases, operative methods, postoperative pathologic findings and postoperative complications. Result: The peak age incidence laid in the 1st to 3rd decade and the ratio of male and female was 1 : 1.5. The most common complaints were cough and dyspnea, but some had hemoptysis. There were 22 cases (81%) of Intrapulmonary bronchogenic cysts and 5 cases(19%) of mediastinal bronchogenic cysts. Thirteen cases (48.1%) showed cystic lesion in simple chest X-ray. Ten cases showed cystic lesion among 13 cases that had taken computed tomography. We found associated disease in 15cases (56%). The inflammatory diseases from infection were many in intrapulmonary bronchogenic cysts and especially, one case showed carcinosarcoma. Mitral regurgitation and Bronchial obstruction could be seen in mediastinal bronchogenic cysts. The 13 cases (48%) were managed by lobectomy, and cystectomy, pneumonectomy, and segemental resection were done in 7 cases (26%), 4 cases (15%), 3 cases (11%) respectively. Cystic contents were mucus in 9 cases, pus in 9 cases, blood in 2 cases, and carcinosarcoma in 1 case. Bronchotracheal communications were in 13 cases (48%). Five cases showed Postoperative complications, which were pneumothorax, empyema, bleeding. Postoperative death could not be found. Conclusion: Almost all patients had clinical symptoms. Severe complications could be associated with bronchogenic cysts. Recently, With the development of diagnostic methods, preoperatively accurate diagnosis is possible; therefore, invasive study has decreased. Bronchogenic cyst is a benign disease. However, because of its clinical symptoms, complications, and possibility of malignant change, immediate surgical treatment is needed.
