BACKGROUND/OBJECTIVES: This study aimed to investigate cancer-specific survival (CSS) and associated risk factors in elderly gastric cancer (EGC) patients. SUBJECTS/METHODS: EGC patients (≥ 70 yrs) who underwent curative gastrectomy between January 2013 and December 2017 at our hospital were included. Clinicopathologic characteristics and survival data were collected. Receiver operating characteristic (ROC) analysis was used to extract the best cutoff point for body mass index (BMI). A Cox proportional hazards model was used to determine the risk factors for CSS. RESULTS: In total, 290 EGC patients were included, with a median age of 74.7 yrs. The median follow-up time was 31 (1-77) mon. The postoperative 1-yr, 3-yr and 5-yr CSS rates were 93.7%, 75.9% and 65.1%, respectively. Univariate analysis revealed risk factors for CSS, including age (hazard ratio [HR] = 1.08; 95% confidence interval [CI], 1.01-1.15), intensive care unit (ICU) admission (HR = 1.73; 95% CI, 1.08-2.79), nutritional risk screening (NRS 2002) score ≥ 5 (HR = 2.33; 95% CI, 1.49-3.75), and preoperative prognostic nutrition index score < 45 (HR = 2.06; 95% CI, 1.27-3.33). The ROC curve showed that the best BMI cutoff value was 20.6 kg/m². Multivariate analysis indicated that a BMI ≤ 20.6 kg/m² (HR = 2.30; 95% CI, 1.36-3.87), ICU admission (HR = 1.97; 95% CI, 1.17-3.30) and TNM stage (stage II: HR = 5.56; 95% CI, 1.59-19.43; stage III: HR = 16.20; 95% CI, 4.99-52.59) were significantly associated with CSS. CONCLUSIONS: Low BMI (≤ 20.6 kg/m²), ICU admission and advanced pathological TNM stages (II and III) are independent risk factors for CSS in EGC patients after curative gastrectomy. Nutrition support, better perioperative management and early diagnosis would be helpful for better survival.

In order to establish the frozen storage method of pork and contribute to the stabilization of pork price physicochemical changes and sensory evaluation of pork, stored at $-20^{\circ}C$ up to the period of 12 months, were analyzed every three months. The drip loss of frozen meat cuts was below 1% regardless of storage months. In the course of storage, pH of frozen half carcass rose a little, while that of meat cuts remained almost the same. WHC(water holding capacity) of frozen half carcass and meat cuts was in the range of $50{\sim}60\;and\;55{\sim}62%,$ respectively and VBN (volatile basic nitrogen) was about $11{\sim}18mg%,$ all of which did considerably change during the storage. TBA(thiobarbituric acid) value was not increased up to the 6th month of storage, but represented a considerable increase after the 9th month of storage, Both tenderness and juiciness of frozen pork were decreased after the 12th month of storage but the axxrptability of frozen pork to the consumers turned out fairly good.

This study was carried out to investigate the effect of dietary palm oil supplementation on the quality of the carcass and meat of Hanwoo (Korean cattle). Thirty-month-old steers were fed on a concentration with or without (control) palm oil for 3 mon prior to slaughter. The samples of M. longissimus were taken from all carcasses and then stored at $4^{\circ}C$ for 9 d. The carcass traits, total myoglobin content, pH value, total reducing ability, and myofibrillar fragmentation index were unaffected by supplementation with palm oil. However, the fat content, water-holding capacity, and tenderness were significantly increased by dietary palm oil (p<0.05). In the fatty acid composition, the palm oil group had a higher palmitic acid (C16:0) content and lower polyunsaturated fatty acids (PUFA) content compared to the control group (p<0.05). The lipid oxidation stability, myoglobin oxidation stability, and color stability were increased by dietary palm oil. It is concluded that supplemental palm oil increased the marbling and storage quality but decreased the PUFA in Hanwoo beef.

For the breeding purpose, in this study we attempted to select a new Lentinula edodes strain by comparing mycelial growth rate, fruit-body quality and mushroom productivity per substrate weight of hybrid strains with parent strains. Nineteen hybrid strains were made by cross of di-karyotic and mono-karyotic to develop strains suitable for sawdust cultivation of L. edodes. Among the nineteen strains, ten were selected by comparing mycelial growth rate on PDA media and wood rot on sawdust-based substrates. The most mushroom harvesting was achieved by 100 days incubation from KFRI 960, KFRI 961, KFRI 962, KFRI 963, KFRI 964, KFRI 971, KFRI 973 and 125 days from KFRI 968, 970. Experiment of incubation periods with the ten strains showed that there were productivity differences between 100 and 150 days incubations. Through comparison of hybrid strains' mushroom productivity it was found that there was no difference in mushroom productivity through crossing high temperature types with high temperature types, crossing low temperature types with high temperature types and crossing unknown temperature types with high temperature types, but there was difference through crossing middle temperature types with high temperature types. Hybrid strains showed better productivity compared with parent strains. Fruiting temperature type analysis of hybrid strains confirmed that strains of high temperature types have a dominant character.

Honey production from approximately 1.6 million colonies owned by about 199,000 Korean beekeepers was almost 23,000 metric tons in 2009. Nosema causes significant losses in honey production and the virus decreases population size. We initiated a survey of honey bee colonies on the blooming period of Acacia to determine the prevalence of Nosema and virus in 2011. Most Korean beekeepers have moved from the south to north of Korea to get Acacia nectar for 2 mon. This provided a valuable opportunity to sample bees originating from diverse areas in one location. Twenty hives owned by 18 beekeepers were sampled in this year. Nosema spore counts ranged from zero to 1,710,000 spores per bee. The average number of nosema spores per bee was 580,000. Approximately 95% of the colonies were infected with Nosema, based on the presence of spores in the flowering period of Acacia. This indicates that Nosema is the predominant species affecting honeybee colonies. Also, the seven most important honeybee viruses were investigated by reverse transcription-PCR. Among them, four different viruses were detected in samples. Black queen cell virus was present in all samples. Chronic bee paralysis virus was detected in 10% of samples. Deformed wing virus was present in only 5% of the samples. Prevalence of Sacbrood virus was 15%. However, Cloudy wing virus, Israel acute paralysis virus and kashmir bee virus were not detected in any of samples.

Purpose: This study was conducted to investigate the antioxidative, collagenase and elastase activities of defatted perilla ethanol extracts. In addition, the possibility of its use as a functional cosmetic material has been studied. Methods: In order to investigate the antioxidant function of the perilla extract, electron spin resonance (ESR) was measured with a spectrometer by analyzing the scavenging ability of diphenyl-β-picrylhydrazyl (DPPH) free radicals. Results: The antioxidant activity of DPPH free radical scavenging activity of the perilla extract was about 68% at 85 ㎍/ml, 85% at 20 ㎍/ml, 90% at 40-100 ㎍/ml, and showed antioxidant ability. The inhibitory activity of collagenase was increased to 4.1% at 20 mg/ml, 12% at 40 mg/ml and 26.7% at 100 mg/ml. The inhibitory activity increased in proportion to the concentration. The inhibitory activity of elastase was increased to 3.8% at 20 mg/ml, 15% at 40 mg/ml, 28% at 80 mg/ml and 35.7% at 100 mg/ml. Conclusions: These results suggest that the ethanol extract of perilla may inhibit the antioxidant activity and the activity of collagenase and elastase to improve the skin aging and wrinkles.

The purpose of this study was to present basic data in the nursing practice for the management of living kidney donor by understanding the nature and meaning of kidney donors, experiences. The research subjects were 11 living kidney donors who had donated from Mar 1991 to Feb. 1994 and discharged from the 3 hospitals in Pusan. Data has been collected by Intensive interview with donors. The data analysis has made by phenomenological method of Van Kaam for understanding the phenomenon and meaning of their experiences. The experiences of kidney donors were analyzed into the 4 situations, that is,'motivation of kidney donor', 'decision time to make kidney donation', 'pre-opperation','after donation'. The descriptive expression and common elements were drawn from original data of each situation on the basis of subjects' own words. From each situation, the com-mon elements of kidney donors' experiences were integrated, summarized and described as follows 1. Motivation of kidney donation They wanted to donate their kidney because of empathy of pain on the groung of love to the recipient and with exppectation of successful kidney transplant or as a solution of economic difficulty. 2. Experiences in deciding to make kidney do-nation In deciding to make kidney donation, donors had love toward the recipients. But they experienced conflict too. 3. Experiences before being operated on donated kidney In experiences from deciding to make kidney do nation to preoperation, donors had love toward the recipients. But they also felt anxiety or dissatisfaction. Therefore, they controlled their mind by their faith, support of medical staff or support of society. And they experienced regret for the sociological cognition or financial apprehension. 4. Experiences after kidney donation After kidney donation, donors experienced satis-faction and accompplishment in spite of mental and physical discomfortness, while they felt sense of loss / disappointment, repentance, regret, and apprehension of progress toward their condition. Thus, kidney donors donated their kidney on the ground of empathy and love to the recipient and with expectation of successful kidney transplant. But during the process of kidney donation, they ex perienced conflict, love, anxiety, regret, apprehension of economy. And after donation, they felt sense of satisfaction and accomplishment, while they felt sense of discomfortness, loss / disappointment, re-gret, repentance, or apprehension of progress toward their condition. This result contribute to nurses' role not only for the management of living kidney donors but also for the management of cadaver donors' family.
