This study was carried out to investigate the possibility for utilization and the effectiveness of citrus byproducts on the nutritional composition and sensory score of Jejudo native pig meat. The groups are consisting of the Jejudo native pig loin without citrus byproduct ($JNP-T_0$) and the Jejudo native pig loin fed with 8% and 15% citrus byproduct during growing and fattening period($JNP-T_1$). The contents of moisture, crude protein, crude fat, crude ash, calorie, cholesterol content Mg, P, K, Na, vitamin $B_1\;and\;B_2$, total amino acid, and total free amino acid content were not significantly different between $JNP-T_0$ and $JNP-T_1$(p>0.05). It was found that palmitic acid($25.301{\sim}27.403%$) was the highest one among saturated fatty acid while oleic acid($42.234{\sim}43.061%$) was the highest among unsaturated fatty acid in both groups. In case of sensory score, the color and aroma of raw meat, and the flavor preference of boiled meat of $JNP-T_0$ were higher than those of $JNP-T_1$(p<0.05). But the taste, texture, juiciness and palatability of boiled meat were not influenced by feeding of citrus byproduct.

Effect of barley bran flour on bread quality was investigated. With addition of barley bran flour, crude protein and ash contents of bread increased, and color of crumb and crust became darker than control group made with pure wheat flour. Content of dietary fiber in bread made with 5% barley bran flour was twofold higher than that of control group. Hardness of bread increased and volume decreased in proportion to bran content. Sensory qualities of 5% barley bran flour-added group and control group were not significantly different, but decreased in 10 and 15% barley bran flour-added groups, revealing optimal content of barley bran flour to be 5%.

Effects of conjugated linoleic acid (CLA) on physico-chemical properties of cooked ground pork patty were investigated for 11 days at $4^{\circ}C$. Pork patties containing 0, 1, 2, and 3% CLA were cooked at $90^{\circ}C$ for 30 min. The contents of crude protein and fat did not change whereas the content of ash and water decreased as the level of CLA enhanced. Lipid oxidation as measured by thiobarbituric reactive substances of patty was inhibited by addition of CLA. CLA treatment also reduced nitrite and cholesterol content and changed fatty acid composition. Consequently, given these positive effects of CLA, it may be assumed that CLA could be used as a fat additive for value-added pork patty.

This study examined the method of making high-quality serial cadastral map with field surveying, the renewal and applications of serial cadastral map which is made for the application of notification of various topographical maps, and related legal and institutional contents. The results of the study are as follows. First, we suggested the way of modification that enables preexisting methods to connect with field surveying in order to improve utilizability of serial cadastral map that is not utilized properly. In addition, we came up with legal grounds from a current law, 'act on surveying watercourses survey and cadastre' for the modification. We also examined legal and institutional factors, the renewal and application of various notifications of topographical maps for efficient application, and the application of modified serial cadastral map for field surveying. Once the current cadastral map is modified based on the results of our study, it is possible that notification of topographical maps gets more accurate, and serial cadastral map can be used for field surveying. In addition, the modification can be utilized for a step-by-step strategy that reduces the existing cadastral map managed as 3 types into the cadastral map managed as 1 type.

Purpose: This study investigated the impact of coronavirus disease 2019 (COVID-19) on women's health nursing clinical practicums in undergraduate nursing schools in Korea during the spring 2020 semester. Methods: A cross-sectional online survey on clinical practicum teaching experiences in the spring 2020 semester was distributed to members of the Korean Society of Women Health Nursing (KSWHN) who taught undergraduate nursing. One faculty member from each of 203 institutions was requested to respond and there were no duplicate participants. Seventy-nine participants (38.9%) responded and 74 responses were analyzed. Descriptive statistics were presented for all survey items. Results: Fifty-two faculty members (70.3%) belonged to universities and 22 (29.7%) taught at colleges. Thirty-eight (51.4%) answered that their institutions had affiliated teaching hospitals. More than half (52.7%) conducted hospital-based clinical practicums either entirely (n=20) or partially (n=19), whereas the rest of them (47.3%) conducted clinical practicums at school or home via online teaching. The typical teaching methods for offline or online education were case conferences, tests or quizzes, scenario studies, nursing skill practicums, (virtual) nursing simulations, and simulated patient education. Most of faculties (93.2%) supported the development of an educational platform to share educational materials and resources, such as case scenarios. Conclusion: Nursing faculty members utilized various teaching methods to enhance clinical skills and mitigate limited clinical exposure during the early stage of the COVID-19 pandemic. The KSWHN should move forward to develop an education platform and modalities for members who face many challenges related to the accessibility and quality of nursing education contents.

D-CATV VOD service provides various contents such as drama and movie with high quality regardless of time and place. As the usage time of the VOD service increases, the viewing time of real-time terrestrial broadcasting is shortened. As the demand for VOD service is high and the number of digital users is increasing, the VOD market is rapidly growing. Therefore this study investigates the age and gender analysis of digital cable TV users and analyzed the usage patterns and audience cases of users. VOD service has been shown to be used by many users for the first time through remote control and free coupons. Non-users of VOD service did not use it because of charge and did not feel the necessity, but some non-users did not recognize the free VOD service.

Pre-harvest sprouting(PHS) refers to germinating seeds in the mother plant before harvesting under low dormancy and humid climate, deteriorating grain quality, and rice yield. Rice varieties with floury endosperm(RFE) have been developed to boost domestic rice consumption by invigorating the processed rice industry, reducing milling and environmental cost. However, the PHS tolerance of RFE is relatively low in the rice varieties with transparent endosperm(RTE) since they soak moisture rapidly due to soft endosperm. In this study, Baromi2(BR2), floury endosperm, and Jomyeong1(JM1), PHS tolerance donor, were crossed to improve PHS tolerance. Major agronomic traits and PHS tolerance test of ten F₇(BR2/JM1) lines were conducted in NICS, 2022. The evaluations of PHS were carried out according to the method of RDA(2012) with slight modifications. Briefly, three panicles were treated and incubated 25℃ in a growth chamber 35 days after the heading date. Ten PHS tolerance promising lines demonstrated floury endosperm. The heading date of BR2 and JM1 was 7/27 and 8/5, respectively. The heading date of promising lines was 7/23~8/10. The PHS rate of BR2 and JM1 exhibited 56.3% and 10.7%, respectively. However, the PHS rate often promising lines demonstrated 2.4%~52.4%, 3 lines significantly lower than BR2. Further studies such as ABA contents are necessary to elucidate the mechanism of PHS tolerance in BR2/JM1. These results may contribute to developing elite RFE lines with improved PHS tolerance.

A total of 180 Arbor Acre broilers (35 days of age) were fed a diet containing 0%, 0.6%, 1.2%, 1.8%, 2.4% or 4.8% conjugated linoleic acid (CLA) for 3 weeks then slaughtered at week 1, 2 and 3. Thigh and breast muscles were seamed out, vaccum-packed prior to storage in a chill for days 7 to analyse thiobarbituric acid reactive substances (TBARS). The accumulation of CLA in breast and thigh muscles was increased significantly (P<0.05) as the CLA level was increased, but no significant difference amongst the treatments. The contents of saturated fatty acids were significantly increased(P<0.05) with an increase of dietary CLA level, but those of unsaturated fatty acids were significantly decreased (P<0.05). The content of mono unsaturated fatty acid (MUFA) was decreased as dietary CLA level increased, even though that of poly unsaturated fatty acid (PUFA) had a little difference between dietary CLA level. Dietary CLA reduced the degree of lipid oxidation in raw chicken meat during storage.

Meat production and quality traits in beef cattle are largely affected by genetic factors. Acetyl-Coenzyme A carboxylase-${\alpha}$ (ACACA) plays a key role in the regulation and metabolism of fatty acid biosynthesis in mammalian animals. The gene encoding ACACA enzyme was chosen as a candidate gene for carcass and meat traits. In this study, we investigated effects of single nucleotide polymorphisms (SNPs) in the ACACA gene on beef carcass and meat traits in Hanwoo (Korean cattle) populations. We have sequenced a fragment of intron I region of the Hanwoo ACACA gene and identified two SNPs. Genotyping of the two SNP markers (g.2344T>C and g.2447C>A) was carried out using PCR-SSCP analysis in 309 Hanwoo steers to evaluate their association with carcass and meat production traits. The g.2344C SNP marker showed a significant increasing effect on LW (p = 0.009) and CW (p = 0.017). Animals with the CC genotype had higher CW and LW compared with TT and TC genotypes (p<0.05). The g.2447A SNP marker was associated with higher MC (p = 0.019). Animals with the AA genotype had higher MC than animals with CC and CA genotypes (p<0.05). Although the degree of linkage disequilibrium (LD) was not strong between g.2344T>C and g.2447C>A in the LD analysis, four major haplotype classes were formed with two SNP information within the ACACA gene. We constructed haplotypes using the HaploView software package program and analyzed association between haplotypes and carcass traits. The haplotype of ACACA gene significantly affected the LW (p = 0.027), CW (p = 0.041) and MC (p = 0.036). The effect of h1 haplotype on LW and CW was larger than that of h3 haplotype. Animals with the h1 haplotype also had greater MC than did animals with h2 haplotype. Consequently, the ACACA gene could be useful as a DNA marker for meat production traits such as carcass yield and meat contents in Hanwoo.
