Objective : The purpose of this study is to discuss the role and ways to improve the position and rights of Korean Medicine Doctors (KMDs) working at long-term care hospitals (LTCHs) through survey analysis. Method : (1) The legal and institutional position of KMDs is studied using current law and related papers. (2) The online survey was conducted through KMD community websites, targeted at KMDs working at LTCHs. Results : (1) Whereas there is perceived added benefit for the eight specializations for a specialist of Western medicine at LTCHs, in the case of a specialist of Korean Medicine, their value is not institutionally recognized at all. (2) A Western inpatient's medical fee is more than a Korean inpatient's medical fee, and the individual fee for the same medical treatment is also higher in Western hospitalization. So, Korean medical hospitalization actually cannot be made. Because of that, Korean Medicine Doctors find it difficult to be primary care physicians. (3) Musculoskeletal diseases and the aftereffects of cerebrovascular diseases were the most common chief complaints addressed in Korean medical consultations. Conclusion : This study shows that KMDs working at LTCHs have suffered many kinds of inequality. That is because of the limited medical scope of the current medical system and real constraints from the gap in Korean-Western medical fees by the National Health Insurance Corporation. Therefore, it is necessary to eliminate these variations along with revising the statute with continuous research.

Purpose: Hypertension has been a major cause of death in Korea since the 1970s, and has resulted in being a significant economic burden to the finances of national health care. The Ministry of Health and Welfare made several efforts. but hypertension control programs in Korea are still non standardized and ineffective. We wanted to investigate the current hypertension control program in public health centers systematically and suggest the direction for future programs. Method: The design of this study is a cross sectional investigation. From September to October in 2002, we sent a set of questionnaires to all PHCs, and 179 centers responded (response rate = 74.0%). The instrument was developed based on components of National health systems. Results: 1) Resources: The department responsible for hypertension control programs is the Department of Health Promotion. Health Education Center, Community Health Center, Citizen's Health Center, etc. The chief personnel of those departments are nurses. but 27.4% of PHCs have no full time nurse for hypertension management programs. PHCs had a lot of teaching materials (nine types per a PHC) and most of the recommended contents were included. But, periodical evaluation and revision were not being made, 2) Management: Nurses' (13.03 9.46 in 23 score) actions for hypertension control were not qualitative, but regular training and evaluation were seldom carried out. Need assessment (25.9%) and evaluation (about 10-20%) for the hypertension control program were indicated as low. 3) Programs: Programs focused on individuals rather than community or public, and 2nd prevention rather than 1st, 3rd prevention. Conclusion: The Ministry of Health and Welfare has to construct the infrastructure for hypertension control programs. Related scholars and committees should develop and declare standardized manuals for hypertension control and the management system, as well.

Objective : To investigate the efficiency of diffusion tensor imaging (DTI) fiber-tracking based neuronavigation and assess its usefulness in the preoperative surgical planning, prognostic prediction, intraoperative course and outcome improvement. Methods : Seventeen patients with cerebral masses adjacent to corticospinal tract (CST) were given standard magnetic resonance imaging and DTI examination. By incorporation of DTI data, the relation between tumor and adjacent white matter tracts was reconstructed and assessed in the neuronavigation system. Distance from tumor border to CST was measured. Results : The sub-portion of CST in closest proximity to tumor was found displaced in all patients. The chief disruptive changes were classified as follows : complete interruption, partial interruption, or simple displacement. Partial interruption was evident in seven patients (41.2%) whose lesions were close to cortex. In the other 10 patients (58.8%), delineated CSTs were intact but distorted. No complete CST interruption was identified. Overall, the mean distance from resection border to CST was 6.12 mm (range, 0-21), as opposed to 8.18 mm (range, 2-21) with simple displacement and 2.33 mm (range, 0-5) with partial interruption. The clinical outcomes were analyzed in groups stratified by intervening distances (close, <5 mm; moderated, 5-10 mm; far, >10 mm). For the primary brain tumor patients, the proportion of completely resected tumors increased progressively from close to far grouping (42.9%, 50%, and 100%, respectively). Five patients out of seven (71.4%) experienced new neurologic deficits postoperatively in the close group. At meantime, motor deterioration was found in six cases in the close group. All patients in the far and moderate groups received excellent (modified Rankin Scale [mRS] score, 0-1) or good (mRS score, 2-3) rankings, but only 57.1% of patients in the close group earned good outcome scores. Conclusion : DTI fiber tracking based neuronavigation has merit in assessing the relation between lesions and adjacent white matter tracts, allowing prediction of patient outcomes based on lesion-CST distance. It has also proven beneficial in formulating surgical strategies.

This study investigated the smoke blocking and control systems for the safety of residents evacuation and for the prevention of smoke spread through the central corridor in the event of central corridor type of intelligent building fire. We offered additional ways of utilizing smoke ventilators and intake ventilation equipment and utilized CFD-based fire simulation program(FDS Ver.5.5.3) in order to analyze the effect. As a result, many differences in the smoke block effect, depending on the application of smoke ventilator and location of installation, was found. In addition, the result was found that larger effect was showed not in the case of application of smoke ventilator in central corridor only but application in fire room. The reason is that the smoke leakage is blocked primarily as air is flowed in the fire room through open door by operation of intake smoke ventilator in the public corridor and secondarily, the smoke leakage to the public corridor could be blocked as fire and smoke were released to the opened smoke ventilator continuously. Especially, the effect was maximized through complex interactions by applying smoke ventilator and intake ventilation equipment in corridor together rather than applying smoke ventilator and intake ventilation equipment independently. The proposed measure through this study shall be considered from architectural plan as one of ways for blocking from smoke spread to the central corridor in the central corridor type of intelligent building. In addition, flaws on regulation shall be established and supplemented.

The purpose of this study was to determine the association between school administrator support as perceived by nutrition teachers (dietitians) and job satisfaction in order to provide data concerning efficient job performance of nutrition teachers, to determine effects of school administrator support on job satisfaction in nutrition teachers, and to provide basic data that could help improve school meals. Major supporters of nutrition teachers (dietitians) were chief administrators (55.3%), principals (27.2%), assistant principals (15.0%), and managers in charge (2.4%). Nutrition teachers (dietitians) scored 3.38 for perception of school administrator support, 3.66 for emotional support, 3.27 for informational support, 3.22 for instrumental support, and 3.11 for evaluation support. Support of nutrition teachers (dietitians) by school managers included emotional support (3.66)>informational support (3.27)>instrumental support (3.22)>evaluative support (3.11). Nutrition teachers (dietitians) scored 3.37 for job satisfaction, as follows: work performance (4.19)>interpersonal relationships (3.39)>job satisfaction in general (3.37)>job itself (3.29)>job environment (3.07)>performance rating and benefits system (2.70). Statistically significant correlation was observed between perception of school administrator support and job satisfaction (r= .771, p< .01). Therefore, school administrators are necessary to provide evaluative supports to nutrition teachers (dietitians), performance assessment, employee benefit packages, and improvement of school meal plans and quality.

Background: Emergencies in dentistry can be classified as medical and dental. Medical emergencies occur mainly during dental treatment in patients with a systemic disease. Dental emergency departments are largely divided into dental emergency rooms located in dental college hospitals and medical emergency rooms located in medical institutions. This study aimed to analyze the characteristics of and provide help to dental emergency patients in a dental hospital. Methods: Overall, 1806 patients admitted to a dental emergency room at Yonsei University Dental Hospital for 1 year were included. The data collection period was from October 1, 2014 to September 30, 2015. An investigator reviewed medical records from the electronic medical record (EMR) system and radiographs. Results: The patients were 1,070 men and 736 women. The sex ratio was 1.45:1. The commonest age group was of 0-9 years, including 451 (25.0%) patients, followed by 20-29 years, including 353 (19.5%) patients, and 30-39 years, including 277 (15.3%) patients. Of the 108 patients transferred to the Severance emergency department, 81 had trauma, 19 were in pain, 4 were bleeding, and 4 had other complaints. Among chief complaints, 1,079 patients (60.3%) had trauma, 564 (31.5%) had pain, and 75 (4.2%) had bleeding. Twenty-three cases (1.3%) were caused by temporomandibular disorder (TMD). Conclusion: Dentists should be able to adequately assess patients in a dental emergency room and treat trauma, pain, and bleeding.

We used polymers of alternating cationic and anionic nature to build up shells on fiber surfaces, strengthen the worn-out fibers and improve paper properties made from such fibers. OCC and ONP pulps were either dipped or salted out in the cationic polyallylamine, polyacrylamide and starch solutions. After centrifugal drying, these were followed by treatments in anionic polyacrylic acid, poly-acrylamide, and starch solutions, respectively. The shell-enhanced fibers were formed into handsheets and their physical properties evaluated. The results show that building multiple shells on worn-out fiber surfaces can strengthen the fibers and paper. The simpler and more practical impregnation-centrifuging treatment provided the desired effects, whereas salting out the polymers produced somewhat superior fibers. The latter process, were impractical, however. The first pair of polymeric shells imparted marked strength improvement, whereas later layers had diminishing efficacies. Overall, the methods can improve fiber quality, attaining paper strength requirements without resorting to expensive measures. Alternate cationic polymer and filler powders were also deposited on fiber surface based on the micriparticle system in an anticipation of stiffness gains. Platy minerals, such as montmorillonite, bentonite, sericite, clay and talc were added following cationic PAM. After dewatering of polymer-pigment shelled fiber of one to 3 pairs of layers, handsheets either calendered or uncalendered were evaluated. The results indicate that regardless of calendaring, stiffness of the handsheets did not improve appreciably while certain other strength properties showed gains. We also attempted the novel starch gel filler addition method wherein tapioca starch and filers (PCC, sericite or clay) were mixed at high solids content of 50% and cooked until gelatinized. The filled handsheets were dried under various conditions and then tested for their properties. Improvements in strengths of modified filled paper were observed.

This experiment was conducted from 1991 to 1993 at the forage experimental field, College of Agriculture and Life Sciences, SNU, Suweon to investigate the effects of previous crop residues on growth and yield of succeeding corn(2ea mays L.) and also to determine the best double cropping system necessary to maximize the total dry matter yield of winter forage crops plus corn for silage. In this experiment, treatments consisted of no crop as a control, late maturing Kodiak rye(Seca1e cereale L.), Bamapoli forage rape(Brassica napus Subsp. oleifera L.), G-sprinter oats(Avem sativa L.), Chief crimson clover(Trifolium incarnatum L.), Jackson Italian ryegrass(lo1ium rnultiJlorum L.), Vantage vetch(Vicia sativa L.) and early maturing Koolgrazer rye(Seca1e cereale L.). Corn leaf number and silking date were not significantly affected by previous crop residues, but the leaf number of corn following Italian ryegrass was reduced by 1.9 relative to no previous crop. The plant height and LA1 were significantly reduced during early development when corn followed Italian ryegrass and late maturing Kodiak rye (p<0.05). The dry matter and estimated TDN yields of corn were significantly reduced when corn followed Italian ryegrass and late maturing Kodiak rye. The yield reductions for corn following Italian ryegrass, late maturing Kodiak rye and early maturing Koolgrazer rye, relative to com when no previous crops were planted, were 34, 17 and 8%, respectively. Therefore, the reduction in corn growth and yield in this experiment could be explained by an allelopathic effect resulting from the Italian ryegrass and rye residues. The highest total dry matter yield of 30,509kg/ha was obtained from an early maturing rye-corn double cropping sequence in combination among the eight cropping systems.

Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney and nervous system, and occurs predominantly in mostly males. The patients with Lowe syndrome are characterized with prominent forehead, thin and sparse hair, protruding ears, congenital cataracts, glaucoma, mental retardation, stunted growth, hypotonia, decrease in muscle mass and tendon reflexes, renal tubular dysfunction, and metabolic bone disease. A 6-year-old boy with Lowe syndrome was admitted to our clinic, with multiple caries and a chief complaint of intermittent pain on the left mandibular molar area. Because of difficulty in management of behavior and his medical problem, general anesthesia was performed for dental care. No specific complication was noticed during dental treatment procedure under general anesthesia and also during periodic recall-checks. General anesthesia itself, however, could be a potentially life-threatening procedure due to patient's biomedical problems. When a dental procedure under general anesthesia is to be required in patient with Lowe syndrome, it may be advisable being teamed with physicians, and general anesthesia duration should be as short as possible.
