The elderly population has been dramatically increasing over the past years, but most of the population has developed chronic diseases and handicaps due to aging. High-intensity resistance training is one of the most effective ways to improve muscular strength, but it is unclear whether body composition and functional fitness would be increased by high-intensity resistance training. The aim of this investigation was to explore whether 12 weeks of high-intensity training would improve muscular strength, body composition, and functional fitness in women over the age of 70 years. Twenty-four participants were randomly assigned to a high-intensity resistance training group (n=8), a low-intensity resistance training group (n=8), and a control group (n=8). The experimental groups exercised 3 days per week for 12 weeks at a local fitness center. An analysis of variance(ANOVA) with repeated measures was used for analysis. The results showed that there was a significant improvement in agility and muscular strength following the high-intensity resistance training. Moreover, Moreover, %body fat and body fat mass decreased significantly after the 12 weeks of high-intensity resistance training(p<0.05). Based on these results, it was concluded that high-intensity resistance training is efficient for women over the age 70 years in increasing their muscular strength and functional fitness and reducing their total body fat mass.

In order to investigate correlation between mother's dental ca re for her children and their dental caries, this study was conducted wi th the dental examination record of 365 children who showed the same number of questionnaires with those examined for dental conditions and questionnaires written by mothers among children between three and six years of age and their mothers in Yeoncheon, Gyeonggi province in June 2004 to estimate frequency and percentage of general properties of subjects and mother's oral health care behaviors for her children by research items, to carry out cross-tabulation analysis and correlation analysis following Chi-square distribution for the presence of dental caries in deciduous teeth and oral health care behaviors, and to use decision tree analysis among data mining techniques for those factors associated with the presence of dental caries in deciduous teeth, and drew the following conclusions. 1. For mother's oral health care behaviors and attitudes for her children, 225 mothers(61.6%) confirmed their children's teeth-brushing; 278(76.2%) used no fluorine; and 286(78.6%) observed their children's teeth, 322 mothers(88.2%) instructed their children in teeth-brushing while 268 (73.4%) provided dental care, 232 mothers(63.7%) treated their children's cavity; 290(79.4%) believed that their children had good dental conditions; and 294(80.5%) answered that they began to provide their children with dental care in deciduous teeth. 2. As for the presence of dental caries in deciduous teeth and dental health care behaviors, there were statistically significant differences in employment, confirmation after teeth-brushing, teeth observation, instruction in time for teeth-brushing, use of fluorine, cavity treatment, time for dental care, and perception of dental conditions(p<0.05). 3. As for correlation between dental caries in deciduous teeth and oral health care behaviors, mothers who worked, who believed that their children didn't have good dental condition, and who thought that it was necessary to begin to provide dental care in permanent teeth were found to get their children to suffer from dental caries in deciduous teeth. Besides, those who failed to confirm teeth-brushing, who used no fluorine, and who failed to observe teeth and gave no instruction in time for teeth-brushing were shown to get their children to suffer from dental caries in deciduous teeth. 4. Variables to determine the presence of dental caries in deciduous teeth were classified by cavity treatment, mother's employment, time for dental care, and observation of children's teeth. The first node to determine the presence of dental caries in deciduous teeth was found to be cavity treatment; the next criteria for classification after cavity treatment were shown to be mother's employment and time for dental care. In case of children with no cavity, they were found to be mother's employment and teeth observation.

Background : There is increased recognition that rigorous approach to functional assessment will complement the assessment of clinical status. This study is to develop the appropriate visual function index in Korean patients with cataracts by the assessment of the reliability, validity of visual function indexes including VF-14. Methods : An prospective study was performed with 92 patients who had undergone either one eye or both eye cataract surgery by 3 ophthalmologists practicing at a university hospital. Patients were interviewed. and clinical data were obtained. Doctors were questioned with self-entered questionnaire forms. Medical record was examined to understand surgery process. The survey was conducted at 1-2 days before cataract surgery. Results : We used following measures : 7 visual function indexes, global measures of patients' trouble and satisfaction with vision, and best-corrected visual acuity(VA) in each eye. 7 visual function indexes showed a high internal consistency reliability (Cronbach's alpha coefficients ${\geq}$ 0.86). The better visual acuity(operated eye, better eye), the higher patient satisfaction with vision, the lower symptom score, the lower patient trouble with vision was correlated with preoperative visual function index scores. Among 7 indexes, VF-12 with the exclusion of 2 items drivings from VF-14 is a high Cronbach's alpha coefficient and correlation coefficient and the highest $R^2$. Conclusion : We conclude that VF-12 is reliable and valid in Korea. So we suggest that in Korea, all items of VF-14, the visual function index, which is in use internationally, ought to be surveyed and VF-12 which has been excluded by 2 items of drivings from VF-14 ought to be used for analysis.

Background : This study was done to assess the relationship among multiple patient outcomes of cataract surgery perioperatively, 3-4 months and 12 months after surgery. The patient outcomes include changes in visual acuity(operated eye, better eye), visual function(VF-14), patient satisfaction, subjective satisfaction with vision, and subjective overall health status. Methods : For the assessment of relationship, prospective study was performed with 92 patients who had undergone either one or both eye cataract surgery by 3 ophthalmologists practicing at a university hospital. Patients were interviewed. and clinical data were obtained. Doctors were questioned with self-entered questionnaire forms. Medical record was examined to understand surgery process. The survey was conducted at 4 stages : preoperatively, perioperatively, postoperative 3-4 months, and postoperative 12 months. Results : The correlations within patient outcomes at 4 stages - the visual acuity of operated eye and that of better eye, patient satisfaction and VF-14, subjective overall health status and relative health status as against others - were found to be positively correlated. The change in the visual acuity of operated eye and better eye was correlated with VF-14 as well as with patient satisfaction. The change was also correlated with overall health status. However, the correlations between variables were decreased as the postoperative period got longer. Conclusion : As for the postoperative clinical patient outcomes, VF-14 is acted to linker between visual acuity - clinical outcomes and overall health status - endpoint outcomes. Therefore. VF-14 is the index of patient-sided and disease-specific outcome for cataract surgery.

To overcome problems of conventional glass ionomers, resin components have been added to glass ionomers. On a continuum between glass ionomers and composites are a variety of blends, employing different proportions of acid-base and free radical reactions to bring about cure. Popular groups defined between the ends are resin-modified glass-ionomers(RMGIs), polyacid-modified composite resins(Compomers) and ionomer modified resins. These groups show different clinical properties, and in selecting these materials for a restoration, one should sufficiently understand these different setting properties. In this study, some difference in the setting characteristics of different groups of hybrid ionomers were examined. Two RMGIs (Fuji2 LC,GC / Vitremer, 3M), three Compomers (Dyract AP, Dentsply / F2000, 3M / Elan, Kerr) were involved in this study. The identification of the setting characteristics of different groups was achieved by a two-stage study. First, thermal analysis was performed by a differential scanning calorimeter, and then the hardness of each group at different depth and time were measured by a micro-hardness tester. Thermal analysis was performed to identify the inorganic filler content and to record the heat change during setting process. The setting process was progressed for each material by chemical set mode and light-cured mode. In the hardness test, samples of materials were prepared with a 6mm-diameter metal ring, and the hardness was measured at the top, and 1mm, 2.5mm, 4mm below at just after a 40 second-cure, and after 10 minutes, 24 hours, and 7 days. Statistical analysis was performed by Mann-Whitney rank sum test to assess significant differences between set modes and types of materials, and by ANOVA and T-test to evaluate the statistical meanings of data at different times and depths of each materials. Followings are findings and conclusions derived from this study. Thermal analysis; 1. Compomers show no evidence of chemical setting while RMGIs exhibit heat output during the process of chemical setting. 2. Heat of cure of RMGIs exceed Compomers. 3. The net heat output of RMGIs through light-cured mode is higher than through chemically set mode. Hardness test; 1. Initial hardness of RMGIs immediately after light cure is relatively low, but the hardness increases as time goes by. On the contrary, Comomers do not show evident increase of the hardness following time. 2. Compomers show a marked decrease of setting degree as the depth of the material increases. In RMGIs, the setting degree at different depths does not significantly differ.

The purpose of this study was to examine relations on the autonomy, nursing performance based on the awareness and satisfaction of electronic medical record system for nurses. This Study was a descriptive survey design using convenience sampling. There were 194 general hospital nurses, who agreed to participate in this study, taken a structured questionnaire during august 2013. SPSS 20.0 version was used for descriptive analysis, frequency, percentage, mean, standard deviation, independent t-test, one-way ANOVA and Pearson correlation coefficiency. The major findings of this study were as follows. The mean score on the awareness of EMR was 3.68, the mean score on the satisfaction was 3.47 and nursing autonomy mean score was 3.25, nursing performance mean score was 3.55. There were significant differences in the awareness according to working field and computer certificate. There were significant differences in satisfaction depending on whether they held computer certificates Head nurses and the above scored significantly higher in nursing performance compared to nurses at the lower position. Also, higher awareness was significantly related to higher satisfaction. Higher satisfaction was significantly related to higher nursing autonomy and performance. The findings of this study imply that nurses need to raise their EMR awareness and satisfaction and make best used of their qualification with their computer certificate.

In this study, the proposal to seek ways to reduce the amount of radiation is drawn by comparing and analyzing CT Dose Index(CTDI) on the pediatric head CT which was performed at the busan regional hospitals, to the national diagnostic reference levels. As a result, it was appeared to exceed the amount of the dose recommendation in order of hospital, general hospital and senior general hospital in the hospital-specific classification and from 2 to 5 year, from 1 month to 1 year and from 6 to 10 year in the age-specific classification. In addition, the amount of the dose recommendation was exceed in order of helical, axial and volume in the scan-specific classification. As the results of the scan range reset to match the diagnostic reference level, the dose reduction showed 11.68%, 15.79% and 20.66% in senior general hospital, general hospital and hospital respectively. In the results of analysing patient average scan ranges which does not deviate from the guideline of patient dose recommendation, there was age of 1 month to 1 year, 2 to 5 year and 6 to 10 year of $03.2{\pm}11.8mm$, $110.5{\pm}14.5mm$, and $117.8{\pm}17.2mm$ respectively.

Objective : To determine the clinical risk factors associated with the mode of delivery decision and to compare cesarean section rates after adjusting for risk factors identified among Korean hospitals. Methods Data were collected from 9 general hospitals in two provincial regions by medical record abstraction during February 2000. A total of 3,467 cases were enrolled and analyzed by stepwise logistic regression. Performance of the risk-adjustment model (discrimination and calibration) was evaluated by the C statistic and the Hosmer-Lemeshow test. Crude rates, predicted rates with 95% confidence intervals, and adjusted rates of cesarean section were calculated and compared among the hospitals. Results : The average crude cesarean section rate was 53.2%, ranging from 39.4% to 65.7%. Several risk factors such as maternal age, previous history of cesarean section, placenta previa, placental abruption, malpresentation, amniotic fluid abnormality, gestational anemia, infant body weight, pregnancy-induced hypertension, and chorioamnionitis were found to have statistically significant effects on the mode of delivery. It was confirmed that information about most of these risk factors was able to be collected through the national health insurance claims database in Korea. Performance of the risk-adjustment model was good (c statistic=0.815, Hosmer-Lemeshow test=0.0621). Risk factor adjustment did lead to some change in the rank of hospital cesarean section rates. The crude rates of three hospitals were beyond 95% confidence intervals of the predicted rates. Conclusions : Considering that cesarean section rates in Korean hospitals are too high, it is apparent that some policy interventions need to be introduced. The concept and methodology of risk adjustment should be used in the process of health policy development to lower the cesarean section rate in Korea.

한국간호 I. 간호행정제도 및 법규의 변천 1. 간호행정기구 한국의 의료행정은 현대의학의 도입과 더불어 1894년 6월 내부에 위생국을 둔다는 규정이 발표됨으로서 시작되었고 1901년 관제개편에 따라 위생국에 보건과와 의무과가 설치되었다. 그 후 1945년 12월 보건후생부 간호사업국내에 보건간호과 기관간호과 조산 간호과가 설치되었고 각 도에는 간호 사업계가 설치되었다. 1948년부터는 보건사회부 의정국내의 조산간호과가 간호 사업과로 개편되었다. 그후 1970년 간호사업과가 간호사업담당관제로 개편되었으며 1981년부터는 간호사업담당관제도 폐지되어 보건국의 가족보건과나 의정국 지역의료과에서 한 명의 간호원이 참여하는 정도로 간호행정기구가 점차 축소되었다. 2. 간호법규 1)면허 1962년 개정된 의료법에 의하여 간호원의 면허는 문교부장관이 인가한 간호교육기관 졸업자중 간호원 국가시험 합격자로 규정하였다. 조산원의 경우는 1914년 처음으로 조산원 면허등록을 시작하였으며 현재는 간호원 면허를 받은 자로서 보건사회부장관이 지정하는 교육병원에서 1년의 정규 교육과정을 필한자로 그 자격을 명시하고 있다. 2) 자격시험 자격시험은 1916년부터 실시되었으며 1920년 이후는 각 도에서 관할 실시하였다. 그 후 1962년부터는 보건사회부장관의 주도하에 국가시험을 시행하였으며 현재는 국립 보건원에서 간호원을 포함한 의료업자의 국가 시험을 주관하고 있다. 3)간호수가 간호원 조산원에 관한 간호수가 관계 규칙은 1911년에 발표된 것으로 간호원의 경우 출장 시에 출장비와 간호료를 환자가 지불하도록 하는 것이었다. 1925년 5월까지는 각 지역별로 간호수가에 차이가 있었으나 동년 6월부터 수가규정이 전국적으로 통일되었다. 그 후 1953년부터는 국공립병원 간호원들에게도 다른 일반 공직자와 같이 직급을 보함으로서 간호직에 대한 보수가 통일되었으며 1971년부터는 간호직 수당이 제정되었다. II. 간호사업의 분야별 발전 1. 임상간호제도의 발전 1)초기의 임상간호 한국에 서양의학을 기초로 설립된 최초의 병원은 1885년 의사 Allen에 의한 왕립병원이다. 그 후 정부에 의하여 1894년 군부병원이 설립되었고, 1899년 내부병원이 1904년에 적십자 병원이 설립되었다. 당시에 이루어진 현대간호는 일본인 간호원들에 의해 전해진 일본식 간호와 선교사 간호원들에 의해 전해진 서구식 간호방식이 있었는데 이 두 간호방법은 문화적 배경이나 사회적 인습에 의한 많은 차이점을 볼 수 있었다. 2) 일제하의 임상간호 이 당시에 이루어진 일본식 간호방법을 보면 간호원들의 주업무가 환자를 위한 간호보다도 의사 보조에 더 치중한 것을 볼 수 있다. 한편 선교계 병원에서는 입원환자에 대해서는 간호원들이 전인간호를 실시하였으며 병원당국과 의사들의 협조로 많은 간호사업의 발전을 가져올수 있었다. 3) 광복 이후의 임상간호 6.25 동란 후 한국에는 병원이 계속 늘어나 현재 20Bed 이상의 전국의 병원수가 431개소이고 이중 80Bed 이상의 종합병원이 148개소나 된다. 각 병원의 간호사업은 간호사업과 또는 간호사업부의 행정체제로 운영되고 있으며 최근에는 간호과정(Nursing Process)의 개념을 도입하여 문제중심 간호기록인 POMR(Problem Oriented Medical Record) 방법을 시도하고 있다. 또한 면허간호원은 매년 중앙회에서 실시하는 보수교육을 10시간 이상 받고 있다.

Purpose: The purpose of this study is to measure the internal and external rotation of shoulder and compare with normal volunteer and patients diagnosed as SLAP lesion. Materials and Methods: Thirty-eight cases (group 1) who had SLAP lesions at shoulder arthroscopy and fourty young volunteers(group 2) were analyzed retrogradely with medical record, intra-operative arthroscopic photo & video for SLAP lesions and the ROM of shoulder Under the interscalene anesthesia, the range of motion of internal rotation and external rotation were measured on flxed scapula and 90 degree abduction of shoulder, and the same method for group 2. We analyzed the results with two sample T-test and Wisconsin signed ranks test. Results: There was a significant difference between group 1 and group 2 for the ROM of shoulder. (IR; p<0.001,ER; p<0.001).For the group 1, internal and external rotation with the arm abducted 90 averaged 50 and 64 degrees and for the group 2, internal and external rotation averaged 77 and 90 degrees with significant difference(IR; p<0.001,ER; p<0.001).Conclusion: The range of motion of shoulder, especially internal and external rotation significantly decreased in SLAP lesions. Our results suggest that a limited rotational motion of shoulder closely related with SLAP lesion.
