Selection of location in food service start-up business is sure to be a shortcut to achievement of business performance, and in this context, it's no exaggeration to say that food service industry is an real estate industry. This study looked into what influence of the location factor in food service start-up business had on sales performance, and intended to verify whether the location factors ultimately influenced business performance consequent on the influence of location factors on start-up business satisfaction. To this end, this study set food service owner-operators as its research subject, and conducted a survey of the operators (of restaurants) located in Anyang-si from December 1, 2016 until January 30, 2017. This study distributed a total of 300 copies of questionnaires, and collected 245 copes, among which this study used 198 copies for empirical study excluding the copies whose reply was unfaithful. This study did empirical analysis of 198 copies using SPSS 22.0 Statistical Package Program, together with the application of frequency analysis, factor analysis and regression analysis. The major results of this study are as follows: First, this study divided the location factors in food service start-up business stores into the four, i.e. accessibility, clustering property, placeness and visibility, etc. Second, the study results showed that accessibility, clustering property, placeness and visibility had significant influence as one in the influence of locational factors on sales performance. Third, this study could understand that start-up business satisfaction had a partial mediated effect in the influence of location factors on sales performance. Resultantly, this study confirmed food service start-up business's own selection of location, and wished to find major factors and a differentiated point in time of selection of location of stores in other fields. Such a result gives an implication that it's necessary to concentrate all efforts to increase sales performance of food service start-up business from the location selection phase, and to make efforts to increase start-up business satisfaction.

Purpose : The objective of this study was to investigate effects of different smoothing kernel sizes on brain tissue-masked susceptibility-weighted images (SWI) obtained from normal elderly subjects using voxel-based analyses. Materials and Methods: Twenty healthy human volunteers (mean $age{\pm}SD$ = $67.8{\pm}6.09$ years, 14 females and 6 males) were studied after informed consent. A fully first-order flow-compensated three-dimensional (3D) gradient-echo sequence ran to obtain axial magnitude and phase images to generate SWI data. In addition, sagittal 3D T1-weighted images were acquired with the magnetization-prepared rapid acquisition of gradient-echo sequence for brain tissue segmentation and imaging registration. Both paramagnetically (PSWI) and diamagnetically (NSWI) phase-masked SWI data were obtained with masking out non-brain tissues. Finally, both tissue-masked PSWI and NSWI data were smoothed using different smoothing kernel sizes that were isotropic 0, 2, 4, and 8 mm Gaussian kernels. The voxel-based comparisons were performed using a paired t-test between PSWI and NSWI for each smoothing kernel size. Results: The significance of comparisons increased with increasing smoothing kernel sizes. Signals from NSWI were greater than those from PSWI. The smoothing kernel size of four was optimal to use voxel-based comparisons. The bilaterally different areas were found on multiple brain regions. Conclusion: The paramagnetic (positive) phase mask led to reduce signals from high susceptibility areas. To minimize partial volume effects and contributions of large vessels, the voxel-based analysis on SWI with masked non-brain components should be utilized.

This study was conducted in order to evaluate the characteristics of air temperature fluctuation inside the Daegeumgul, Ondaldonggul, and Seongnyugul Caves, which are the most representative limestone caves in Korea, and also to assess the effects of air temperature on cave temperature. Temperature was measured hourly at three sites in Daegeumgul, Ondaldonggul, and Seongnyugul Caves from April 13 to June 25, 2019. Additionally, air temperature data for the areas around the caves was provided by the Meteorological Administration. Using this collected data, the basic statistical measure of fluctuation characteristics over time was ascertained, and time series analyses were performed. Wide variation of temperature was exhibited in the order of the cave entrance, the cave water inflow point, and the midpoint. Cave temperature was observed to increase gradually during the study period. There was a vast range in temperature at the Daegeumgul station located approximately 150 m outside the cave, but it remained nearly constant beyond the midpoint. Although the effect of air temperature was not significant due to the influence of visitors, the effect of air temperature on cave temperature gradually decreased from the entrance to the interior. At Ondaldonggul, there was a wide range in temperature recorded at the entrance due to the influence of air temperature, but it stayed almost constant in the interior. However, at the site where cave water flows into the cave, temperature was influenced by the cave water temperature. At Seongnyugul, there was a distinct fluctuation in temperature recorded at the cave entrance, while the middle of the cave remained nearly constant. Temperature fluctuated due to the air temperature at the entrance, while at the middle of the cave, measurements were expected to be affected to a greater extent by the lake water temperature than by the air temperature. However, this pattern was not observed. According to the time series analysis results, in all caves, fluctuations of air temperature affected cave temperature after approximately one hour. Cave size and structure, water presence, the entrance's size and shape, air flow, and visitor patterns can all influence cave temperature. Therefore, consideration of these factors is very important in the pursuit to clearly understand cave temperature characteristics.

This study investigated the preference and recognition of cooked rice mixed with multigrains. The data for the analysis was collected from 464 people who were residing in Seoul, Gyeongsang and Jeolla area, and analyzed by the SPSS 18.0 program. The result showed that 77.8% of the respondents liked cooked rice mixed with multigrain, showing significant difference by age (p<0.001) and occupation (p<0.01). Of the respondents, 33.8% consumed cooked rice mixed with multigrains at least once a day, showing significant difference by gender (p<0.01), age (p<0.001) and occupation (p<0.001). The most popular type of grains to mix with rice were, in order, black rice (3.8)> brown rice (3.7)> barley (3.7)> proso millet (3.4)> foxtail millet (3.4)> SoRiTae (3.3)> sorghum (3.2)> adlay (3.2)> mung bean (3.1)> buckwheat (3.0)> BacTae (2.8). A total of 32.5% of the respondents answered that 21~30% was proper mixing ratio of multigrains-added cooked rice, showing age (p<0.001), occupation (p<0.001) and resident area (p<0.05). Three or four kinds of grains were preferred to mix cooked rice, showing significant difference by age and occupation (p<0.001). Of the respondents, 43.1% chose price reduction as the most desired improvement of multigrains in the market. Most of the subjects had affirmative view intake of cooked rice mixed with multigrains, but recognized that multigrains were expensive. From these results, this study will provide basic information for the increased availability of multigrains and optimization of the multigrain ratio mix.

The purpose of this study was to examine dietitians' perception of importance about standards of foodservice management associated with long-term care hospital accreditation. This study was carried out through a postal survey consisting of 500 questionnaires, and 157 returned questionnaires were used in the statistical analysis. The results were summarized as follows. Average scores of perception of importance were 4.54/5 points in foodservice production management domain, 4.56/5 points in foodservice facilities management domain, and 4.70/5 points in foodservice sanitation domain. The average scores of importance of long-term care hospitals without accreditation were significantly (P<0.05) lower than those of hospitals with accreditation in items of 'establishment of ventilation equipment in kitchen', 'establishment of hand-washstand in toilet (warm-water, soap)', 'setup of sterilizing foothold in entrance of kitchen and toilet', 'division and use of knife, chopping board, gloves, and utensils before and after cook', 'establishment of cleaning plan and cyclic practice', and 'recording of receiving diary'. Results indicate that there is a need to supplement a casebook of regulations by suggesting detailed and critical limits in the case of below average points of importance. A manual, including HACCP standards for foodservice management of long-term care hospitals, is needed, along with education and webpage for comparing notes on accreditation of long-term care hospitals.

Objectives : When a patient who attempts suicide visits the emergency room, it is important that the departments of emergency medicine, internal medicine, and psychiatry communicate with each other and prioritize treatment. This study was conducted to verify the effectiveness of the multidisciplinary emergency consultation system (ECS) for drug intoxicated patients. Methods : We retrospectively analyzed the data from medical records prior to the ECS, from July 2017 to May 2018, and after the ECS, from July 2018 to May 2019, to verify the effectiveness of the system. Results : After the ECS, admission to open wards was significantly higher than to the intensive care units (χ²=8.567, p=0.014). In addition, the proportion of consultations to the department of psychiatry among patients admitted to other departments tended to increase (χ²=4.202, p=0.053), and the time required for consultation response decreased (Z=-2.031, p=0.042). As a result of the consultation, the proportion of the patients who had been transferred to the department of psychiatry was increased (χ²=4.692, p=0.043), and the time spent to transfer tended to decrease (Z=-1.941, p=0.052). Conclusions : After implementing the ECS for drug intoxicated patients, unnecessary intensive care unit admissions, consultation response time, and the time spent to transfer were reduced, and the rate of consultation referrals and transfer rates increased. This means that the multidisciplinary consultation system rapidly provided essential medical services to patients at lower medical costs.

The development of an industry including distribution sector is influenced by not only government policy but the related firms' behaviors. Recently the large-scale retailers have had more enormous channel power than any other distributors including monopolistic makers. Now is the time for government to prepare some policies against the unfair transaction behaviors by large-scale retailers. In this paper I tried to inquire into the distribution competition policy from a political correspondent point of view related with the transition of distribution system. For the purpose of this article I compared the case of Korea with Japan. According to the results so far inquired, there are some commons and differences in the cases of the two. Some suggestions are as follows. Considering the predominant position the concept of large-scale retailers is to be extended from a single store to numerous chain stores in the political level. Government needs to examine the standard propriety for large-scale retailer; the size of selling area and amount of sales a year. When a large-scale retailer store is to be established, it need to be taken a permit or a pre-inspection. The Fair Trade Commission have to secure the neutrality from Government's strategies. And government should find out the examples of unfair transaction behavior types and prepare some proper guidelines continually. For the last time statistical data by distributors are to be fitted out and the actual investigations for estimating the effects of government policies need to be enforced.

The physical and chemical characteristics of soils in a small watershed were investigated and the effect of geology and land use on soil quality were examined by using multivariate statistical methods, principal components analysis and discriminant analysis. The soil developed from andesite had finer texture and higher contents of water extractable inorganic components, clay, and mafic minerals than the soil developed from granite. It is considered that the accumulation of salts in the farmland soils indicated by electrical conductivity, contents of cations and anions and pH was caused by fertilizer input during cultivation. The low contents of organic matter in the farmland soils was due to the enhanced oxidation of organic matter by tillage and by the harvest of crops. The contents of inorganic components are increased as following order: upland > orchard > paddy field > forest. The high contents of water soluble $SO_4\;^{2-}$ of paddy soils is due to the oxidation of sulfides mineral formed during the flooding period during the air-dry and extraction. The results of principal components analysis show the difference of soil quality was controlled by geology and land use. PCI indicate the input of fertilizer, mineral weathering and ion exchange reaction by application of nitrogenous fertilizers. The results of two discriminant analyses using water extractable inorganic components and their ratios by land use were also clearly classified by discriminant function 1 and 2. In discriminant analysis by components, discriminant function 1 indicated the effect of fertilizer application and increased as following order: upland > orchard > paddy field > forest soil. The investigated and predicted data for land use from discriminant analysis showed similar results. The discriminant analysis can be used as a useful method certifying the change of land use.

In Korean history, vegetables were the major side dishes of meals and originally korean diets were based on vegetables. But recently people prefer meat dishes rather than vegetables and traditional vegetable cooking seems to be disappeared. So it is needed to be positioning the importance of vegetables in food culture of Korean. In present study, history of vegetable eating was reviewed and recent consumption pattern were analyzed. 1. Since the era of the three Kingdom's and Koryo dynasty, the kinds of vegetables varied and at Chosun Dynasty people used similar kinds of vegetables as nowadays except a few things. A Garlic and mug wort had been used from the age of tribes to present and an egg, apple, cucumber, lettuce from the three Kingdom and a bamboo sprout, a taro, a burdock, a radish, a turnip, a stone-leek, a scallion, a Chinese cabbage, a marsh mallow, a spinach and a crown daisy from Koryo Dynasty and a pepper, a pumpkin, a tomato, a cabbage, a salary, a kale, a turnip and a beet from Chosun Dynasty to present. A guard, a water shield plant, a yam and wild plants would have been used before but they would not use any more. 2. Current vegetable consumptions of Korean is 232.2kg/person/yr and comparing with world mean consumption(101.9kg), Koreans still eat the largest amount of vegetables than any other countries and among Asian countries, Koreans consume more vegetables than China(203.5kg) and Japanese people(111.6kg) do. 3.The most frequently consumed vegetables were vegetables for seasonings such as a garlic or stone-leek and for kimchi such as a Chinese cabbage, radish, and carrot. But from data of Korean National Health and Nutrition Survey(2001), kinds of vegetables which people had were only 72 items showing that the kinds of vegetables were limited. 4. A lot of wild plants that would have been used for famine relief are now disappeared and on the other hand, it is increasing of some new and foreign vegetables and herbs. Cooking methods and intake pattern of vegetables are changed and varied so a traditional cooking method such as namuel is less preferred than before. But vegetable wrapping and green vegetable juice, eating uncooked vegetables(sang-sik) are very popular.

Purpose : The purpose of this study was to compare the clinical features of staphylococcal scalded skin syndrome(SSSS) isolated methicillin-resistant Staphylococcal aureus(MRSA) with those of SSSS isolated methicillin-sensitive Staphylococcal aureus(MSSA) in children. Methods : We retrospectively reviewed the medical records and microbiological results of 36 cases of SSSS who were admitted to the Pediatric Department of Ulsan Dong-Kang General Hospital from Jan. 1999 to Dec. 2003. Results : Among 36 cases, there were 7 generalized types, 1 abortive type in MRSA group and 5 generalized types, 6 abortive types in MSSA group. The peak incidence of age was between 2 and 5 years in both groups. SSSS were diagnosed with increasing frequency. Most of MRSA group were diagnosed in 2003(6/8). The peak seasonal incidence was fall and winter in both groups. Facial lesion was observed in all cases followed by flexural lesion in both groups. Staphylococci were isolated from the skin and throat most frequently in both groups. Upper respiratory illness and conjunctivitis were most common preceding infections in both groups. Among 8 cases of MRSA group, 4 cases were treated completely with ampicillin-sulbactam. There was no significant difference of mean duration of admission between MRSA group and MSSA group. Conclusion : There was no significant difference of clinical features between MRSA group and MSSA group although generalized types of SSSS were more common in MRSA group than in MSSA group.
