The purpose of this study was to investigate the treatment pattern of patients with neuropathic pain (NeP) in Korea through computerized database of Health Insurance Review and Assessment Service (HIRAS) over three years' period from 2003 to 2005. The results showed that the numbers of treatment visits were the highest for diabetic neuropathy (DN), followed by postherpetic neuralgia (PHN) and trigeminal neuralgia (TN) in order. Top 3 specialties for treatment visits due to NeP conditions were neurology, neurosurgery and anesthesiology. While cost of a treatment visit was higher in anesthesiology and emergency clinics compared to other clinics, there was a tendency to increase costs for visits to clinics of rehabilitation medicine and family medicine over the three years. Cost of dental visits was relatively high for TN, atypical facial pain (AFP) and atypical odontalgia (AO). Surgeries frequently applied to patients with NeP were sympathetic plexus or ganglion block, block of peripheral branch of spinal nerve and cranial nerve or its peripheral branch block. Most common prescribed medication were anticonvulsants, anti-inflammatory analgesics and anti-psychotic drugs while anti-inflammatory analgesics were overwhelmingly frequently prescribed for AO and glossodynia. Based on the results of this study, NeP disorders more relevant to dentists were AO, TN and AFP, TN of which seems to be the most important in terms of patients' number and cost for treatment visits. This indicates that dentists, especially oral medicine specialists should actively participate in management of TN, AO and AFP and share relevant information with patients and community.

The objective of this study was to provide information on difficulties in performing tasks of employees of the Center for Children's Foodservice Management (CCFSM) to obtain information as a resource for improving work performance. Data were collected from employees working at the CCFSM over a period of 6 months until December 2013. The recruitment period was from 16 December, 2013 to 30 January, 2014. A total of 228 employees (79.7%) participated in the study, and 227 completed questionnaires were analyzed. Statistical analyses were performed on data utilizing the SPSS V20.0. Employees tasked with 'nutrition guidance visits', 'hygiene safety guidance visits', and 'teaching to cook visits' who worked outside of the office frequently had difficulties with 'physical exhaustion'. They reported that 'working outside of the office encumbers later office work' and that 'employees' suggestions for changes are not easily accepted in child-care facilities. The following statements in the questionnaire were highly rated by each of the employees in charge of 'Gathering training' and 'Budget management': 'As a gathering training is conducted within the working hours of child-care facilities, participation rate is low' and 'The differences in regulations of consignment organization, local government, and KFDA are confusing'. This study also suggests that CCFSMs should have authority over child-care facilities, which demonstrate no desire for improvement even after CCFSM employees offer several suggestions for better foodservice or deliberately avoid participating in CCFSMs without good reasons. Besides, CCFSMs are supported by the KFDA and can lessen the workload of child-care facilities in developing educational materials for better foodservice.

The present paper examined the stress and ADL (activities of daily living) index in relation to the characteristics of the elderly in nursing homes. For this study, questionnaires were given to 110 seniors in the N-district of Seoul, and S-myeon, Hoengseong-gun, Gangwon Province from May 1 to September 30, 2013. For data analysis, t-test, correlation analysis, and multiple regression analysis were performed using the SPSSWIN18.0 program. The analysis of actual proof was made at a significance level of 5 percent. The findings from the analyses were as follows: first, the relocation syndrome into nursing homes has a positive correlation with the stress of deficient family visits in the category of daily stresses; second, depression has a positive correlation with the stresses of deficient private time and space and deficient family visits in the category of daily stresses; third, weight control has a positive correlation only with the stress of deficient private time and space in the category of daily stresses, whereas a nutrition deficiency has positive correlation with the stress of deficient family visits in the category of daily stresses. These findings may serve as ground source data for establishing policies regarding the stresses in relation to the characteristics and ADL index of the elderly in nursing homes.

The Korea Air Force(KAF) has operated freight flights based on the prefixed time and route schedule, which is adjusted once in a month. The major purpose of the operation of freight flights in the KAF is to distribute necessary supplies from the home air base to other air bases. The secondary purpose is to train the young pilots to get more experiences in navigation. Each freight flight starts from and returned to the home air base everyday except holidays, while it visits several other air bases to accomplish its missions. The study aims to forecast freight demand at each base by using time series analysis, and then it tried to optimize the cost of operating flights by solving vehicle routing problem. For more specifically, first, several constraints in operating cargos were defined by reviewing the Korea Air Force manuals and regulation. With such constraints, an integer programming problem was formulated for this specific routing problem allowing several visits in a tour with limitation of maximum number of visits. Then, an algorithm to solve the routing problem was developed. Second, the time series analysis method was applied to find out the freight demand at each air base from the mother air base in the next month. With the forecasted demands and the developed solution algorithm, the oprimum routes are calculated for each flight. Finally, the study compared the solved routing system by the developed algorithm with the existing routing system of the Korea Air Force. Through this comparison, the study proved that the proposed method can provide more (economically) efficient routing system than the existing system in terms of computing and monetary cost. In summary, the study suggested objective criteria for air routing plan in the KAF. It also developed the methods which could forecast properly the freight demands at each bases by using time series analysis and which could find the optimum routing which minimizes number of cargo needed. Finally, the study showed the economical savings with the optimized routing system by using real case example.

Two experiments were conducted to compare the feed intake patterns and growth performance of Meishan and Yorkshire growing pigs. Experiment 1 was carried out over a 6-wk period and used 48 barrows with equal numbers of purebred Meishan (M) and Yorkshire (Y). Pigs were allocated to four groups of 12 pigs consisting of equal numbers of M and Y. Initial BW were $36.4{\pm}0.32kg$ and $42.1{\pm}1.41kg$ for M and Y, respectively. Experiment 2 was carried out over a 5-week period and used 48 pigs consisting of equal numbers of both barrows and gilts and of crossbred Meishan$\times$Yorkshire (MY) and purebred Yorkshire (Y) animals. Pigs were allotted to 6 pens of 8 pigs, with 4 single- and 2 mixed-genotype groups (initial $BW=28.5{\pm}0.99kg$). In both experiments, pigs were given ad libitum access to a grower diet (17% crude protein, 0.9% lysine, 3365 kcal/kg ME) via feed intake recording equipment (F.I.R.E.). Pigs carried an ear-tag transponder with an unique identification which allowed the time, duration, and size of individual meals to be recorded. In Exp. 1, Y had higher ADG (721 vs 353 g, p<0.01), daily feed intake (DFI; 2.338 vs 1.363 kg, p<0.01), made more frequent visits to the feeder per day (NFV; 18.5 vs 7.7, p<0.01), had a shorter feeder occupation time per visit (FOV; 7.4 vs 12.9 min, p<0.01), and ate less feed per visit (FIV; 130 vs 177 g, p<0.01) than M pigs. Feed consumption rates (CR) were greater for Y compared to M (19.3 vs 14.8 g/min, p<0.01). Feeder occupation time per day (FOD) was longer for Y than M (114.3 vs 82.8 min/pig, p<0.01). Yorkshire pigs visited the feeder more frequently between 0800 and 1100 h. Meishan pigs showed more frequent feeder visits between 0600 and 0800 h, and between 1600 and 2100 h when feeding competition with Y was reduced. In Exp. 2, there was no effect of genotype or group composition on DFI, ADG or gain:feed ratio. Crossbred pigs (MY) made fewer feeder visits (12.6 vs 17.7, p<0.01), and had greater FIV (124 vs 98 g/visit, p<0.01), and longer FOV (8.11 vs 7.24 min/visit, p<0.01) and FOD (112 vs 100 min, p<0.05) than Y pigs. Results of this study suggest substantial genetic variation in feeding patterns as well as in growth performance.

Objective : The aim of this study was to investigate the number of measurements and visits for blood pressure measurement. We also analyzed the change of blood pressure based on the measurement method and measurement interval. Methods : Data of three clinical trials evaluating the effect of acupuncture, moxibustion, and qigong for pre and mild essential hypertension were used. Blood pressure was measured 3 times each visit with 1 or 5 minutes interval, and it was checked until $3^{rd}$ visit. Two trials used sphygmomanometer and another one trial used automatic device for blood pressure measurement. Results : The mean difference between $1^{st}$ and $2^{nd}$, and $2^{nd}$ and $3^{rd}$ measurement were significant in systolic (p<0.001) and diastolic blood pressure (p<0.001). However, in automated measurement or measuring with 1 minute interval, the difference between $2^{nd}$ and $3^{rd}$ was not significant. The mean of $1^{st}$ and $2^{nd}$ measurements was also significantly different from the mean of all three measurements in both systolic (p<0.001) and diastolic blood pressure (p<0.001). While the difference between each visit was not significant in diastolic blood pressure, the systolic blood pressure difference was significant between $1^{st}$ and $2^{nd}$ visit in automated and manual measurement. Conclusion : The mean of two measurements and three measurements were significantly different. The change of blood pressure was different according to the method and interval of blood pressure measurement.

The purpose of this study is to compare the differences between first visits and the recurred time of TMD patients about the number of visits, the treatment plans, the symptoms and the results after the conservative treatments. This could lead us to assess the prognoses of TMDs treated conservatively. We investigated 54 patients who have visited the Department of Oral Medicine in PNUH from 1991 to 2001, diagnosed as TMDs and treated conservatively with medications, physical therapies and splints. The treatments were terminated since the subjects have shown much improvements and resumed when TMDs recurred from 1992 to 2002. We researched the diagnoses, symptoms, the number of visits, the treatment plans and the results comparing the time before and after the treatments were carried out and following are the results. 1. Both the primary and the recurred groups improved after having been treated conservatively. 2. Both the primary and the recurred groups showed no differences in pains and MCOs when they first visited though the noises and LOMs turned out to be more serious in primary group. 3. Both the primary and the recurred groups had no differences in pains, noises, LOMs, MCOs when the treatments were over. 4. The results of treatments were not affected by treatment plans, sex, diagnoses in both primary and recurred groups. 5. Most of the patents tended to visit less than 10 times in recurred patients.

Background: Inhaled corticosteroids (ICSs) are the most essential medication for asthma control. Many reports suggest that the usage of ICSs improves not only the control of asthma symptoms but also prevents exacerbation. We investigated whether increases in ICS prescriptions are associated with decreases in asthma exacerbation in the clinical practice setting. Methods: We retrospectively analyzed the database of adult asthma patients who had visited a tertiary referral hospital, the Asan Medical Center between January 2000 and December 2009. The number of emergency department (ED) visits, admissions, intensive care unit (ICU) care, deaths, and ICS prescriptions were analyzed to evaluate the time trend of asthma exacerbation as a function of the ICS prescription rate during the ten years. Results: The numbers of ED visits, admissions, and episodes of ICU care decreased during the ten years (p<0.001, p=0.033, p=0.001, respectively) while the number of ICS prescriptions increased (p<0.001). We found a correlation between the number of ICS prescriptions and the number of ED visits, admissions, or ICU care. For these outcomes, the correlation coefficients were r=-0.952, p<0.001; r=-0.673, p=0.033; r=-0.948, p<0.001, respectively. Conclusion: The number of ICS prescriptions increased during the past ten years while the number of asthma exacerbations decreased. Our results also showed a negative correlation between the ICS prescription rate and asthma exacerbation in the clinical practice setting. In other words, an increase in ICS prescription may be a major cause of a decrease in asthma exacerbations.

The objective was to determine the relationship between feed intake levels and patterns, and growth performance and body composition of barrows and gilts using automatic feed intake recording equipment (F.I.R.E.). This system records the time of visits to the feeder and the duration and size of meals for individual animals housed in groups. Ninety-six crossbred pigs were grown from $33.4{\pm}0.51$ to $109.7{\pm}1.39kg$ live weight over a 13-week period. Eight mixed-sex groups of 12 pigs were used and 4 dietary treatments were compared giving 2 pens per treatment. The dietary treatments consisted of corn-soybean meal diets with differing protein levels which ranged from 14.7% to 19% between 30 to 55 kg, from 13.3% to 16.9% between 56 and 85 kg, and from 12.3% to 16.8% for the remainder of the study. Animals were ultrasonically scanned to measure loin-eye area and backfat thickness to estimate carcass fat-free lean content at the beginning and end of the study. Barrows had higher daily feed intake than gilts (2.67 vs. 2.46 kg resp. p<0.05) which was the result of a longer feeder occupation time per visit (4.77 vs. 4.54 min, resp. p<0.05), higher feed consumption rates (30.4 vs. 29.0 g/min, resp. p<0.05), and higher feed intakes per visit (136.9 vs. 126.8 g, resp. p<0.01). Gilts had less backfat and greater loin-eye area than barrows (p<0.05). Diet had no significant effect on growth performance and had limited impact on feeding patterns. Body weight showed high correlations with ADG (r=0.74), feed intake per visit (r=0.51) and feed consumption rate (r=0.69). Positive correlation were also found between daily feed intake and feed intake per visit (r=0.45), feeder occupation time per day (r=0.56), and feed consumption rate (r=0.55), and between daily feed intake and backfat thickness (r=0.32) and feed consumption rate and loin-eye area (r=0.32). There were negative correlations between number of feeder visit per day and daily feed intake (r=-0.54), and between feed intake per visit and number of feeder visits per day (r=-0.43). However, correlations between feed intake traits and carcass traits were generally low. Visits to the feeder were greatest during the morning (0700 to 1100 h) and lowest during the evening and nighttime. These results highlight limited variation among the sexes in feeding patterns and suggest important relationships between feeding behavior and feed intake.

This study made a descriptive analysis of the cumulative amount and rate of sports medical care utilization during the 24th Seoul Olympic Games by the participating athletes, officials, etc. The sports medical care utilization was a component of the total medical care use and was basically caused by the prevention and treatment of sports injuries. The analytic data were derived from the Olympic Health Management Information System(OHMIS) of the SLOOC and the Korea Athlete Trainer Association(KATA). These were analyzed according to the quantity of physician visits and the utilization rate, which was the amount of utilization divided by the total number of participating persons. The results were as follows: Firstly, the sports medical care utilization by the persons participating in the Seoul Olympics amounted to 17.9% of the total medical care utilization. The venue medical services utilization accounted for 54.7% of the total physician visits, which was larger than the village medical center's utilization. The number of physician visits per hundred persons during the 2 week period in the venue clinic was 3.03 and that of the village medical center was 2.51, therefore, the total was 5.54. Secondly, athletes accounted for 82.3% and officials 12.2% in the sports medical care utilization by participants. These results were because athletes, who were directly related to the games, called extremely often on the physicians. The utilization rate of sports medical care by athletes was 34.29. Thirdly, the sports medical demand according to type of therapy could be ranked from high to low in the following order: sports massage, thermal therapy, and electrical stimulation treatment, etc. The department of physical therapy in the village medical center was used a great deal. Fourthly, the trend of daily sports medical care utilization by the athletes showed a bell shape centering around the opening day of the Seoul Olympic Games. The utilization rate of athletes was 2.3; however, that of officials was 0.6. Lastly, the sports medical demand was calculated according to the continents, and Central America, Africa and Middle-East Asia proved to have a higher rate of sports medical care utilization than the more powerful and industrialized continent or regions.
