The cooked surf clam meat was treated with BHA or EDTA, and then dehydrated by means of hot-air dehydration or sun drying. The dehydrated products were packed in glass bottle and stored for three months in the dark place. After three month storage, the pigment loss and water absorbing capacity of dehydrated products were compared with those of directly after dehydration. Both of the sun dried and hot-air dehydrated surf clam products showed a great deal of pigment loss during storage. The BHA treatment prior to dehydration of surf clam meat had good effects on the pigment retention, and the EDTA treatment had a weak effect on it during storage. The rate of rehydration of dehydrated surf clam products had markedly decreased during storage. And it could be seen that there was little difference among the rate of rehydration of the BHA or EDTA treated product and untreated one during storage.

The raw surf clam meat was pretreated with BHA, EDTA or $NaHSO_3$. The pretreated meat was chopped with chopper, and spread the chopped meat on nylon net, and then dehydrated with cabinet type hot air dryer. In the surf clam meat flake process, the pretreating and the copping steps prior to final dehydration improved the pigment retention and texture of the products. The chopping steps prior to dehydration reduced the dehydration time of surf clam meat. The BHA treatment prior to dehydration of mashed surf clam meat had an outstanding effect on the pigment retention during a process of dehydration and storage. The surf dam meat flakes reabsorbed water more rapidly about two times than the dehydrated natural surf clam meat products. The surf clam meat flakes stored for three months in the dark place showed less pigment loss than the exposed ones, and the former reabsorbed water more rapidly than the latter.

Ideal rotator cuff repair is to maintain high fixation strength and minimize gap formation for optimizing the environment of biologic healing of tendon to bone. Among the current repair techniques, the suture bridge technique is superior to single- or double-row repair in ultimate load to failure, gap formation, restoring anatomical footprint and achieving pressurized contact area. The suture bridge technique also minimizes gap formation and has rotational and torsional resistances allowing early rehabilitation. However, despite superior biomechanical characteristics of the suture bridge technique, there is no evidence that these mechanical advantages result in better clinical outcomes. Furthermore, there is no difference in failure rates between the double-row repair and suture bridge techniques. An appropriate repair technique should be determined based on tear size and pattern and tendon quality.

To determine rapid and reliable analytical method for ochratoxin A detection in cereal-based Korean traditional foods, ochratoxin A content was measured by high-performance liquid chromatography (HPLC) with immunoaffinity column clean-up. Recoveries of ochratoxin A in tested samples ranged from 68.4 to 85.3%. Occurrences of ochratoxin A were 15, 10, and 5% for Kochujang, Deonjang, and Kanjang, respectively. None was detected in Sunsik (mixed cereals). Average levels of ochratoxin A ranged from $0.5\;to\;1.3{\mu}g/kg$, lower than maximum residue level of $5-50{\mu}g/kg$ of ochratoxin A recorded in foreign food code.

Recently hospitals are implementing a One Stop Service as part of patient-care service. With the One Stop Service, medical treatment including consultation, inspection, and results are changing to be made available in one visit. Therefore most examinations are reserved for the same day; however, there are cases in which additional visits are necessary because of certain properties related to exams. This study compares and analyzes the number of reinspections before and after reforms. By designating the order of priority for BMD examinations and implementing education from information obtained in the OCS E-manual update, the number of reinspections for wards was reduced from 58 to 21, Outpatient departments were reduced from 51 to 12, and errors in reservations made by employees in the department of radiology were reduced from 98 to 11. Reinspections can be reduced with full understanding the factors related to reinspection and a background check prior to inspection in order to determine the order of priority for inspections. This will also reduce workers' stress and increase their efficiency and at the same time decease patient dissatisfaction and improve hospital reliability.

Since the introduction and operation of BF certification, a total of 6,432 certificates has been issued until February 2020, of which educational research facilities make 1,091 cases (754 preliminary certification, 337 main certification) out of 6,237 buildings, acquiring BF certification of about 20%. Qualitative evaluation is conducted with focus on the three items of BF-certified building evaluation index, which are medium facilities, internal facilities, and sanitary facilities, and major keywords are the deducted through the Text Mining analysis of the derived results. As a result, problems with access paths occurred in the case of the facilities, and assessment indicators for users were found to be necessary among the assessment of the steps of the internal facilities. Finally, we could see that sanitation facilities needed to improve toilets installed in residential development facilities. Based on the results obtained, the study seeks to suggest directions for improving the evaluation index required for BF-certified school facilities.

This study analyzed the characteristics of chemical accidents, including the accidents occurring each year according to status, type of accident, accident cause for chemical substance transporting accidents. The major aim of this study was to provide information on the chemical accidents that occurred involving chemical substance transporting accidents from 2013 to July - 2016. The total incidence of chemical transporting accidents was 77 cases; 74 cases occurred by the spill & leakage type. The main cause of the accidents analyzed was traffic accidents (41 cases). Forty-six accidents were related to hazardous chemical substances. Among the 46 hazardous chemical substances involved in transporting chemical accidents, 46% of the accident substances were hydrogen chloride. For the prevention and response to accidents occurring during the transportation of chemicals, it is necessary to complement the precautions for chemical accidents caused by transportation accidents and chemical spills and leaks of chemicals. In addition, when the chemical transport of an accident occurs, it is necessary to apply a chemical transport safety system for chemical transfer.
