Objectives: To review studies evaluating effects of acupuncture on pain and depressive symptoms in fibromyalgia. Methods: Quantitative evidences (RCTs) were systematically reviewed. Literature were searched for a combination of fibromyalgia and depression (The Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, medline (via PubMed), Kmbase, KISS, ScienceON, OASIS, CiNii, CNKI). Quantitative research findings were critically appraised by Cochrane risk of bias (RoB) tool and pooled. Meta-analysis was then conducted using Review Manager (RevMan) 5.4. Results: Eighteen studies were selected. American College of Rheumatology (ACR) classification criteria for Fibromyalgia Syndrome was most frequently used as diagnostic criteria for fibromyalgia. As for outcome measurement, Hamilton Rating Scale for Depression (HAMD), Visual Analog Scale (VAS), and Total Effective Rate (TER) were used most commonly. Meta-analysis of ten studies revealed that both Depression and VAS scores of the Acupuncture+Western Medicine group were significantly lower than those of Western Medicine group (Depression: SMD, -0.94, 95% CI, -1.17 to -0.70; VAS: MD, -1.51, 95% CI, -1.83 to -1.19). Also, TERs of both Acupuncture group and Acupuncture+Western Acupuncture+Western Medicine group were significantly higher than those of the Western Medicine group (OR: 2.38, 95% CI: 1.29 to 4.41; and OR: 7.40, 95% CI: 3.41 to 16.07). There was no significant difference in Depression or VAS score between the Acupuncture Group and the Western Medicine Group. Conclusions: Acupuncture might be an effective option for pain and depressive symptoms of fibromyalgia when it is combined with Western Medicine treatment. For more accurate results, more types of Korean medicine treatment should be conducted.

The author is the first man who tried to use an anesthetic on insect specially for silkworm in orde to evaluate the silkworm health and silk yielding ability and the obtained results are as followings. 1. The necessary ether vapor induction for narcosis on silkworms is varied by the glowth of the silkworm which the larger worm is, the longer induction is required. For instance, it was 2∼3 minutes for the worms of third day fifth instar silkworm in case use of ether anesthetic. 2. The longer anesthetic induction for silkworms, the longer recovery needs from anesthesia. In case five minutes ether vapor induction, silkworms recovered narcosis during in 5∼130 minutes which had varied very much by the health variation. 3. The ether induction caused silkworm to vomit digestive juice from a few per cent of the worms, but the chloroform induction showed majority of the worms to vomit the digestive juice out of mouth. So, the ether was found as better anesthetic for silkworms. 4. When ether induction last more than 20∼30 minutes, the recovered silkworms can eat mulberry, but when it gets more than three hours they can not eat mulberry. And when it last more than ten minutes, the silkworm may eat mulberry leaf, but they can not spinn cocoon properly. 5. In case five minutes ether induction for silkworms on third day fifth instar, the stronger variety is, the rallier recovered from narcosis. 6. The recovering duration from narcosis varies regarding with each worm health which shows Poisson′s distribution even in a same variety silkworm. 7. The female worms recover from narcosis earlier than male worms which means the female worm is stronger than male one. 8. The later recovered silkworm from narcosis spinned more rich cocoon silk and ended with smaller pupae weight. Such a tendency showed until at some recovery duration, then the silk yield droped down on the worms recovered in more longer duration. The author (Choe) had named such a relation curve as "Silk Yield Curve against Silkworm Health." 9. The silk yield or cocoon layer ratio had varied from 13 to 27% even in a same worm varity cocoon which showed serious variation and call attention carefulness for the duplication work of a variety silkworm eggs. 10. Not always the rich silk yielding worm is the best worm during the silkworm selection and it should be considered with the silkworm health evaluation. 11. At present situation, only specific breeding expert is allowed to join in the selection service because of need many years experience by use of visual observation, but the ether anesthesia method may help such an evaluation with more accuracy and easy way even for the people in fresh on the field. 12. The effect of the narcosis on the silkworm for the next generation or hybrid worm will be reported in next publication.

Sweat contents were investigated for using those data to forensic purpose. The experiments of identifying sweat contents were as follow: 1) measurement of amino acids (aspartic acid, serine, glycine etc) by HPLC, 2) anions ($Cl^-$, $F^-$, and $SO{_4}^{2-}$) by IC and 3) trace elements (Cu, Zn, Li, B, etc.) by ICP-MS. Amino acid contents in sweat are varied with individual samples and glycine, threonine, alanine, valine and histidine are detected as the prime one. The detected anions are $Cl^-$(2167~4073 ppm) and $F^-$(454~582 ppm) mostly. Trace elements of Rb, Zn and Cu are detected and those concentrations are relatively very high. The compositions of sweat can be influenced by various factors (diet, anthropometric, characteristics, physical fitness, age, gender and the state of the health).

Improving the taste of rice in the breeding process is one of the important goals. However, it takes a lot of time and effort to select lines with good grain quality. MAS related to rice quality can help quickly and accurately select the elite lines in breeding programs. QTL qTV9, derived from Wandoaengmi 6, has been reported as a marker associated with improved glossiness of rice (Park et al., 2019). To confirm the function of QTL qTV9, 186 RILs derived from Hwayeong/Wandoaengmi6 were cultivated on ordinary planting cultivation for five years. The average DTH of Hwayeong and Wandoaengmi 6 was not significant at 99 and 97 days, respectively, but the averages of TV (toyo value) were 72.6 and 86.0, respectively. The DTH and TV of RIL vary from year to year. In 2017-2018, the average DTH was 98 days, which was significantly higher than the other three years. In 2018 and 2021, the average TV was 79.5 and 86.5, respectively, which were significantly higher than in other years. As a result of correlation analysis, DTH in the different years showed highly significant positive correlations (r = 0.71-0.92) from 0.71 to 0.92, whereas TV showed positive but weaker correlations (r = 0.42-0.71). The correlation between DTH and TV in each year was significant but weak (r = 0.25-0.64) and there was no correlation in 2017. The TV (77.6-88.7) of RILs with QTL qTV9 was significantly higher than that of RILs without qTV9 (72.6-84.9) for all five years. As a result of analyzing TV by DTH group, the TV of the lines with qTV9 in DTH groups (93-97) and (98-103) showed a significantly higher trend for all 5 years. And TV was not significant in DTH groups A, B, E, and F. This may have been influenced by factors such as insufficient populations between groups or differences in harvest timing. This study is expected to be used as data for improving the glossiness of cooked rice in breeding programs, and further study of the QTL qTV9 marker is required.

Objective: Jining Grey goat is a local Chinese goat breed that is well known for its high fertility and excellent meat quality but shows low meat production performance. Numerous studies have focused on revealing the genetic mechanism of its high fertility, but its highlighting meat quality and muscle growth mechanism still need to be studied. Methods: In this research, an integrative analysis of the genomics and transcriptomics of Jining Grey goats compared with Boer goats was performed to identify candidate genes and pathways related to the mechanisms of meat quality and muscle development. Results: Our results overlap among five genes (ABHD2, FN1, PGM2L1, PRKAG3, RAVER2) and detected a set of candidate genes associated with fatty acid metabolism (PRKAG3, HADHB, FASN, ACADM), amino acid metabolism (KMT2C, PLOD3, NSD2, SETDB1, STT3B, MAN1A2, BCKDHB, NAT8L, P4HA3) and muscle development (MSTN, PPARGC1A, ANKRD2). Several pathways have also been detected, such as the FoxO signaling pathway and Apelin signaling pathway that play roles in lipid metabolism, lysine degradation, N-glycan biosynthesis, valine, leucine and isoleucine degradation that involving with amino acid metabolism. Conclusion: The comparative genomic and transcriptomic analysis of Jining Grey goat and Boer goat revealed the mechanisms underlying the meat quality and meat productive performance of goats. These results provide valuable information for future breeding of goats.

In order to estimate the sedimentation rates of continental shelf and slope of Ulleung Basin in the Southwestern East Sea, $^{210}Pb,\;^{226}Ra\;and\;^{137}Cs$ were simultaneously measured by a well-type high purity germanium(HPGe) gamma detector. $^{137}Cs$ was used to determine whether the sediment were affected by bioturbation or not, and to judge the accuracy of estimated sedimentation rates. The estimated sedimentation rates decreased exponentially from slope to basin - 0.6 cm/yr in the continental shelf, $0.3{\sim}0.4$ cm/yr in the slope, and below 0.2 cm/yr in the margin of Ulleung basin. From our and other research results, we suggest followings about sediment transport of the study area. The sediment particles were transported by coastal current from south to north through the Korea Straight. And much of them were accumulated in the shelf area. And then, the rest of sediment particles were deposited in the lower slope and the southwest margin of the basin. Also the excess $^{210}Pb$ profiles indicate that the depositional processes in the study area may have been very complicate.

These studies were carried out to investigate the effects of the size of follicles, semen types, capacitation methods, and additions of hormones, estrous cow serum(ECS), fetal calf serum(FCS), bovine follicular fluid(BFF) and matured cumulus cell(MCC) to the medium on in vitro maturation and fertilization of bovine follicular oocytes. The ovaries were obtained from slaughtered Korean native cows. The follicular oocytes surrounded with cumulus cells were recovered by aspirating follicular fluid from the visible follicles of diameter 3~5mm. The follicular oocytes were cultured in TCM-199 medium containing hormones, FCS, ECS, BFF and MCC for 24~48hrs. in an incubator with 5% $CO_2$ in air at $38.5^{\circ}C$ and then matured oocytes were again cultured for 18~20 hrs. with motile capacitated spermatozoas the TCF (Tyrode calcium free) solution containing $100{\mu}g/ml$ of heparin. The results obtained in these experiments were summarized as follows: 1. The oocytes classified as "A,B,C,D and Degenerative" depending morphological integrity and those 61.4%, 12.1%, 19.2%, 4.2% and 3.0% of the total oocytes recovered, respectively. The maturation and fertilization rate of the A, B, C class follicular oocytes, cultured in the TCM-199 medium supplemented with 10% FCS were 89.1%, 78.0%, 52.6% and 78.1%, 66.1, 33.3%, respectively. 2. The average number of the follicular oocytes recovered from follicles size, 1~2mm, 3~5mm and above 5mm in diameter were 67, 98 and 63, respectively. The maturation and fertilization rate of the follicular oocytes, cultured in the TCM-199 medium were 56.7%, 82.5%, 46.0% and 44.8%, 71.4%, 28.6%, respectively. 3. The fertilization and cleavage rate of the follicular oocytes, inseminated with spermatozoas of epididymal cauda, neat and frozen semen were 63.3%, 73.3%, 70.0% and 32.7%, 37.8% 38.3%, respectively. 4. The fertilization and cleavage rate of follicular oocytes, fertilized with capacitated spermatozoas by heparin, BFF and HIS methods were 70.0%, 53.8%, 34.2% and 38.3%, 23.1%. 17.1%, respectively. And the fertilization and cleavage rate were higher method of heparin. 5. The maturation and fertilization rate of follicular oocytes, cultured in the TCM-199 medium supplemented with 5%, 10%, 15%, 20% and FSH, HCG, 17, $\beta$-estradiol were 76.0~82.3% and 26.2~70.0%, and those values were higher the supplementation than non-supplementation. 6. The maturation and fertilization rate of the follicular oocytes cultured in TCM-199 medium supplemented with 5~20% ECS and FCS were 74.0~80.6%, 26.2~30.0% and 71.7~76.9%, 51.9~58.0%, and the values were higher the supplement of ECS than FCS. 7. The maturation rate (68.0~64.6%) and fertilization rate(59.6~60.4%) of follicular oocytes cultured in TCM-199 medium supplemented with 10% FCS and 20~30% BFF were higher than those of follicular oocytes cultured TCM-199 medium supplemented with 10% FCS and 10% and 50% BFF. 8. The maturation rate(76.5%) and fertilization rate (61.7%) of follicular oocytes cultured in TCM-199 medium supplemented with 10% FCS and $1{\times}10^6/ml$ MCC were higher than those of follicular oocytes cultured in TCM-199 medium supplemented with 10% FCS and $1{\times}10^{{4}{\sim}{5}}/ml$ and $1{\times}10^8/ml$ cumulus cells.

Purpose : As several epidemics of aseptic meningitis had been reported in Korea since 1990, the need of epidemiologic study about enteroviral infections was recognized. We studied epidemiologic and clinical features of enteroviral infections in children. Methods : We analyzed the seasonal occurrence of enteroviral infections and age, sex and clinical diagnosis of the children admitted to five branch hospitals of Hallym University and diagnosed to have enteroviral infections by culture from January 1996 to December 1998. Results : Enterovirus was isolated in 126 out of 245(51.4%) stools, 15 out of 89(16.8%) nasopharyngeal aspirates and 195 out of 1,835(10.6%) cerebrospinal fluids. There were 273 echoviruses(Echo)(197 Echo 30, 46 Echo 9, 17 Echo 6, 13 unclassified), 24 coxsackieviruses B(CB)(11 CB 2, 2 CB 5, 11 unclassified), 7 coxsackieviruses A 24 and 32 unclassified enteroviruses. Yearly number of isolates was 65(46 Echo 9) in 1996, 239(197 Echo 30) in 1997 and 32(15 CB: 9 CB 2) in 1998. Epidemics of enteroviruses occurred mainly during the months May to October. The mean age of the infected children was $62.1{\pm}38.0$ months and 74.6% of the patients were younger than 7 years of age. There were 203 boys and 100 girls and 79.3% of the patients were diagnosed as aseptic meningitis. Conclusions : We confirmed that enteroviral infections occurred in epidemics from late spring to fall during the study period. Enteroviral infections occurred predominantly in boys and the preschool children. Aseptic meningitis was the main illness in the hospitalized children.

To use as a fundamental data for the sustainable agriculture, which is nowadays a major trend to keep the productivity and conserve the environment, 487 paddy soil samples were collected from 21 regions of the Gyeongnam Province and analyzed the chemical characteristics and microbial population of the soil. The microbial population densities were bacteria $298{\times}10^5$($4{\sim}3000{\times}10^5$ range), fungi $63{\times}10^3$($2{\sim}441{\times}10^3$ range), actinomycetes $19{\times}10^5$($0.2{\sim}1250{\times}10^5$ range), Bacillus sp. $53{\times}10^4$($4{\sim}890{\times}10^4$ range) and Pseudomonas sp. $198{\times}10^4CFU\;g^{-1}$($4{\sim}1724{\times}10^4CFU\;g^{-1}$ range), respectively. The microbial populations of the soil were in general higher in southern area than in the northern area of the Gyeongnam Province. The average ratio of bacteria/fungi population was 473. As soil clay content increased, the populations of aerobic bacteria, actinomycetes and Pseudomonas sp. were remarkably decreased. The ratio of aerobic bacteria and fungi was 1554 in sandy loam and clay loam 1144, while Bacillus sp./fungi ratio was 11 in clay loam and 10 in loam. On the topographical differences, aerobic bacteria and Bacillus sp./fungi ratio were the higher in coastal plains than any other areas. The microbial population densities from different soil types were generally lower in ill-drained paddy field than those of other paddy field. The content of $P_2O_5$, K, Ca, $NO_3-N$ and EC in soil were positively correlated to the population densities of aerobic bacteria, actinomycetes, fungi, Bacillus sp. and Pseudomonas sp.. The soil organic matter and Mg content were also positively correlated to the population densities of aerobic bacteria, actinomycetes, fungi and Bacillus sp.

The objectives or this study were to examine reed value or waste onion in duck. Experimental chicks (Cherry Valley F$_1$, 1day old, 350 chicks) were randomly assigned in 8 treatment groups, each 45 chicks, and man-aged for 7 weeks (3 kg BW, 49 days old). Treatments were control, 3%, 6% of chopped onion-fed, 5%, 10% of onion extract fed, 6% of onion meal, 3%, 6% of fermented onion-fed. Feed intake was significantly (P<0.05) high in control group, but ADG was high in 3% chopped onion-fed group. Feed requirement was very efficient in all treatment groups except 6% fermented onion-fed group. Dressing rate was high in 5% onion extract-fed group, but it was not significant. Abdominal fat was the highest in control and 6% fermented onion-fed group and lowest in 6% chopped onion-fed group. Cholesterol content was lower in all treatment groups than in control group, but it was not significantly different. Stearic acid ($C_{18:0}$) content was significantly low in all treatment group (P<0.05). However, arachidonic acid ($C_{20:4}$) content was higher in treatment group than in control group. In result, onion diet was not significantly effect on palatability, feed intake, ADG in ducks. Duck meat of onion-fed contained low cho-lesterol and high unsaturated fat content.
