This experiment was planned to find a proper postharvest handling technique of 'Niitaka' pears for storage. The effect of polyethylene film wrapping, ethylene scrubber, and Prolong application on maintanence of freshness were compared in prestored fruit.(60 days at $0^{\circ}C$). Weight loss was confirmed to be a major factor responsible for freshness loss during storage. Polyethylene film wrapping greatly reduced weight loss during storage but increased light skin browning. Also, in long-term storage, polyethylene film wrapping appeared not to be appropriate due to the severe occurrence of tissue senescence and/or senescence breakdown. Prolong application was found not to be effective on reducing weight loss as well as keeping freshness. Ethylene scrubber in polyethylene film wrapping effectively reduced the occurrence of light skin browning.

A 4-year-old female Shunauzer dog was referred to the Veterinary Teaching Hospital of Chungbuk National University due to anorexia and depression. The dog had a history of regular walking on grass fields, weight loss, and hyperthermia $(40.6^{\circ}C)$. In the physical examination, lymph node enlargement was confirmed. Complete blood count result revealed leukocytosis and thrombocytopenia but there was no decreasing of red blood cells. On blood chemistry, serum ALP, GGT, CPK, and LDH were elevated. Abdominal radiograph showed splenomegaly. Anaplasma platys infection was suspected with inclusion body-like substances in platelets on blood smear. Anaplasma platys was confirmed by PCR. On the basis of laboratory examination, final diagnosis was anaplasmosis. Treatment was followed for 3 months with tetracycline and doxycycline. The patient was monitored every week during the treatment. The patient has recovered to normal condition without any clinical signs. We are going to emphasize the need of PCR technique in diagnosis and to report the possibility of long term treatment more than two months in rickettial disease.

Fresh ginseng has a limited storage life due to the quality change caused by microbial spoilage as well as physiological deterioration. The present study investigated the effects of 1-methylcyclopropene (1-MCP) treatment, an inhibitor of ethylene action, on the microbial growth and quality maintenance of fresh ginseng during storage. Harvested fresh ginsengs were treated with $1{\mu}L{\cdot}L^{-1}$ 1-MCP for 20 hours at $4^{\circ}C$ and then stored at room temperature (RT) for 18 days or low temperature ($4^{\circ}C$) for 160 days. After 18 days of storage at RT, the percentage weight loss in 1-MCP treated fresh ginseng (8.3%) is lower than that of control (10.1%). During long-term storage at $4^{\circ}C$, weight losses were increased slightly until 120 days without difference between non-treated and 1-MCP ginsengs. In contrast, after 120 days of storage at $4^{\circ}C$, higher increase in weight loss was observed in non-treated ginsengs than in 1-MCP treated ginsengs. Respiration rate and ethylene production of fresh ginseng were reduced by 1-MCP treatments at RT. The 1-MCP treatment also resulted in lower microbial population compared to those of non-treated ginsengs at RT. However, in ginsengs stored at $4^{\circ}C$ for short-term (45 days), no differences were noted in weight loss and microbial population between 1-MCP treated and non-treated ginsengs. Major ginsenosides was not changed by 1-MCP treatment during the 7 days of storage at RT. Results suggest that 1-MCP treatment can be used to maintain the freshness of ginseng at room temperature for short term storage and at low temperature for long term storage. 1-MCP treatment could be applied on fresh ginseng to avoid deleterious effect of exogenous ethylene during storage and shipping.

The objectives of this study were to examine calpain activity and meat tenderness by three different feeding patterns in Korean native cattle (KNC). Total forty-five animals were assigned each fifteen in long term restriction feeding (LTFR), long-term restriction feeding and hormone treatment (LTFR-tH), and short term non-restriction feeding (STFNR), respectively. Concentrate was restricted based on body weight in exp 1 and 2. However, it was fed ad libitum in exp. 3. Hormonal implantation was made with $M-PO^{TM}$ for bulls and with $F-TO^{TM}$ for heifers at 18, 20, 22 months of age in exp. 2. Animals were purchased (3-5 month old) from local cattle market and managed in two local farms and university research unit at three different years. Animals were slaughtered at 24 months for long-term trial and at 18 month for short term-trial. Loin and tender loin muscle was used for calpain activity and meat quality. Calpain proteolytic system was not changed by treatment. However, calpastatin activity was low in short-term trial. The calpain and calpastatin activity is reciprocal relationship, therefore, the high calpain activity may effect on quality grade. The shear force value was decreased as the processing of aging after postmortem. On the other hand, the cooking loss was significantly higher in short-term than in long-term trial, and then gradually decreased by the aging. Hormone implants to increase meat yield influenced to calpastatin activity more powerfully than calpain activity to meat tenderness. In meat color-a*, there was not significant difference in loin. Meat color-b* was decreased as postmortem aging time increased in tenderloin. Western blots were done to learn whether these proteins are degraded during postmortem storage and whether this degradation temporally parallels the decrease of shear force value. Vinculin was detected at 0 day and 1 day and degraded after 3 day. In conclusion, Calpain activity was affected slightly on meat tenderness. But meat tenderness was influenced by calpastatin, more effectively.

At present, the selecting system and analytic estimation criterion on repair materials and methods of the deteriorated RC structures have not yet been set up in domestic. Under these circumstances, deterioration such as shrinkage crack, corrosion of rebar has been often occurred after repair, and this finally results in too frequent repairs. In this study, three types of repair methods were experimentally investigated by the accelerating test in a combined deterioration chamber and long-term field exposure test. Three types of repair methods applied in this study belong to a group of polymer cement mortar, which is commonly used in repair works. According to the results of this study, durability of repair mortar layers and corrosion properties of recovered rebar could be investigated in short period by the accelerating test in a combined deterioration chamber, which can simulate the condition of repeated high-and-low temperature and repeated dry-and-wet environment, spraying chloride solution and emitting $CO_2$ gas. After 36 month long-term filed exposure test in the coastal area, harmful macro-cracks are observed in the polymer cement mortar layer of some repair methods. These crack are considered to result from drying shrinkage of polymer cement mortar. Also, after 36 month exposure, amount of corrosion area and weight loss of rebar are found to be different according to the types of repair methods.

Purpose: The aim of this study was to develop long-term storage technology for Chinese cabbage in order to extend the period of availability of freshly harvested products. The scope of the paper deals with the use of a cooler with a remote monitoring and control interface in conjunction with use of packaging film. Methods: A cooler with a real time monitoring system was designed as a low-temperature storage facility to control temperature and relative humidity (RH). The effects of storage in high-density polyethylene (HDPE) plastic boxes, 3% chitosan dipping solution, polypropylene film (PEF) with perforations, and mesh packaging bags on physiological responses were investigated. The optimal storage temperature and humidity for 120 days were below $0.5^{\circ}C$ and 90%, respectively. Physiological and biochemical features of cabbage quality were also analyzed: weight loss, texture, and sugar salinity, chlorophyll, reducing sugar, and vitamin C contents. Results: The cooler with a remote monitoring and control interface could be operated by an HMI program. A $0.5^{\circ}C$ temperature and 90% humidity could be remotely controlled within the cooler for 120 days. Postharvest freshness of Chinese cabbages could be maintained up to 120 days depending on the packaging method and operation of the remote monitoring system. In particular, wrapping the cabbages in PEF with perforations resulted in a less than a 5% deterioration in quality. This study provides evidence for efficient performance of plastic films in minimizing post-harvest deterioration and maintaining overall quality of cabbages stored under precise low-temperature conditions with remote monitoring and a control interface. Conclusions: Packaging with a modified plastic film and storage in a precisely controlled cooler with a remote monitoring and control interface could slow down the physiological factors that cause adverse quality changes and thereby increase the shelf life of Chinese cabbage.

A 14-year-old, castrated male, domestic shorthair cat was referred for gastrointestinal (GI) signs, including nausea, regurgitation, anorexia, and weight loss. Abdominal ultrasonography revealed thickening of the wall of the gastric and proximal duodenum, moderately enlarged mesenteric lymph nodes, and coarse echotexture of the splenic parenchyma. The results of the feline leukemia virus test were positive. Based on gastrointestinal endoscopic characteristics and histopathological examinations, low-grade alimentary lymphoma was identified in multiple regions of the gastrointestinal tract. The patient was treated with oral prednisolone and chlorambucil chemotherapy, and the clinical signs resolved gradually. During serial follow-up, ultrasonographic findings demonstrated decreases in the duodenal wall thickness and size of the abdominal lymph nodes over a period of 550 days. Survival time was 886 days with prednisolone and chlorambucil chemotherapy. This report describes clinical features, imaging findings, endoscopic characteristics, histopathological features, and long-term management with chlorambucil chemotherapy in a case of feline low-grade alimentary lymphoma.

The purpose of the study was to examine nutritional management and nutritional care demands of home-visit care service and the nutritional status of serviced elderly. The survey was carried out from $5^{th}$ to $21^{st}$ of January, 2011 among 37 In-Home Service institutions. The number of elderly surveyed by 143 care helpers was 281. Analysis was performed for 203 subjects (male: 44, female: 159). The age distribution was from 50 to 99 years. The grading by long-term care insuranceshowed 18,2% on level 1 and 2, and 81.8% on level 3. For the disease treatment, the proportion of implementing diet treatment turned out to be very low. The proportion of subjects living with their children was 45.3%, and living alone was 29.1%. The proportion of home-visit care among types of In-Home Service was 70%. Subjects who needed additional necessary diet management service turned out to be 40.9%. Diet management was the most necessary services from all levels. MNA (specifiy MNA) scores were significantly (p < 0.001) associated with BMI, mid-arm circumference (MAC), calf circumference (CC), intake problems, and weight loss during the last 3 months. For studied elderly, 45.3% were malnourished, and 46.8% were at the risk of malnutrition by MNA score. Based on the result of this survey, the nutritional care was not systematic on the In-Home Service. Prevention and management of the disease was much better than the treatment to improve the quality of life. We conclude that nutrition management is necessary for the elderly. To improve nutritional status of elderly in home care services, systematic nutrition management should be implemented.

Background: Nursing home resident care is an ongoing topic of public discussion, and there is great interest in improving the quality of resident care. This study investigated the association between nursing home employees' job satisfaction and residents' satisfaction with care and medical outcomes. Methods: Employee and resident satisfaction were measured by questionnaire in 175 skilled nursing facilities in the eastern United States from 2005 to 2009. Facility-level data on residents' pressure ulcers, medically unexplained weight loss, and falls were obtained from the Centers for Medicare and Medicaid Services Long-Term Care Minimum Data Set. The association between employee satisfaction and resident satisfaction was examined with multiple and multilevel linear regression. Associations between employee satisfaction and the rates of pressure ulcers, weight loss, and falls were examined with simple and multilevel Poisson regression. Results: A 1-point increase in overall employee satisfaction was associated with an increase of 17.4 points (scale 0-100) in the satisfaction of residents and family members (p < 0.0001) and a 19% decrease in the incidence of resident falls, weight loss, and pressure ulcers combined (p < 0.0001), after adjusting for staffing ratio and percentage of resident-days paid by Medicaid. Conclusion: Job satisfaction of nursing home employees is associated with lower rates of resident injuries and higher resident satisfaction with care. A supportive work environment may help increase quality of care in the nation's nursing homes.
