We assessed the pesticide residues in the medicinal agricultural products distributed in Korea. Pesticide residues in 72 samples were analyzed using the QuECheRS method for 339 pesticides, using GC-MS/MS and LC-MS/MS. The pesticide residues were below the maximum residues limit (MRL) in 42 samples (58.3%); however, they exceeded the MRL in 5 samples (6.9%). These included 43 types of pesticides; 20 fungicides and 23 insecticides were detected 75 times and 58 times, respectively. Tebuconazole and carbendazim were the most detected fungicides, each 11 times. The levels of acetamiprid, cadusafos, chlorpyrifos, flubendiamide, fluopyram, and triazophos exceeded the MRL in Gogi berry, Omija, and Reishi mushroom. All of them were positive list system (PLS) items that lacked pesticide residue standards. Therefore, authorities should monitor the distributed medicinal agricultural products.

Adenoviruses are an important cause of respiratory tract infections, particularly in infants, young children, and immuno-compromised patients. In this study, we investigated the characteristics of adenoviruses isolated from outpatients with acute respiratory illness in Gyeonggi province of South Korea during 2009-2011. Adenoviruses were detected in 102 of 1,622 (6.3%) specimens by using PCR or real-time PCR with viral specific primers. 76 isolates were obtained from 102 specimens using the A549 cells. Serotypic distributions of isolated adenovirus were analyzed by sequencing of hexon gene. Six different serotypes were identified, which included adenovirus serotypes 1-6. Adenovirus 3 (n=40, 52.6%) was the predominant serotype. The predominant types of adenovirus every year were serotypes 1 and 3 in 2009, serotype 3 in 2010, and serotype 5 in 2011, respectively. Adenoviruses 1, 2, 4, 5, and 6 were isolated sporadically throughout the study period. Adenovirus 3 was present both during outbreaks and in sporadic cases. These results indicate that adenovirus 3 played major causative agent of adenovirus outbreaks in Gyeonggi province of South Korea during 2009-2011. Continuous surveillance for specific serotypes of adenovirus that can cause outbreaks is important.

'Sanggang', a new cultivar of Agrocybe aegerita, was bred with mating between monokaryotic strains isolated from 'GMAG45109' and 'GMAG45107' in Mushroom Research Station, Gyonggi Province A.R.E.S. in 2009. The optimum temperature for the mycelial growth of 'Sanggang' was 26 to 28$^{\circ}C$ on PDA(potato dextrose agar) medium. The optimum temperature for the primordia formation and fruiting body development of 'Sanggang', was 18 to 20$^{\circ}C$. In the bottle cultivation of 'Sanggang', the period of spawn running was around 38 days at 22 to 23$^{\circ}C$ and the period from scratching of inoculum to harvest was 12 days. These characteristics of 'Sanggang' were not different from those of 'Mihwang' (control). 'Sanggang' had brown-colored pileus, whereas 'Mihwang' had yellowish brown-colored one. In bottle cultivation, 'Sanggang' hada little smaller but stronger stipe and pilus than 'Mihwang', and 'Sanggang', as well as 'Mihwang', had upright stipe. And 'Sanggang' was shown to have lower veil opening ratio than that of 'Mihwang' at harvest time.The yield of fruiting bodies of 'Sanggang' was 134 g/850ml bottle, which was similar to that of 'Mihwang'. Resistance of'Sanggang' against Trichoderma spp., as well as 'Mihwang', was weak. Freshness of 'Sanggang' was maintained for 13 days under storage temperature 4$^{\circ}C$, while that of 'Mihwang' was maintained for 10 days.

To analyze physical and ecological characteristics of sand streams, Cheongmi, Yanghwa and Bokha streams on the similar environment were Lnvestigated and estimated. According to the estimation results of physical structures, ecological properties of the Cheogmi and Yanghwa streams were classified as 'fair to good', and the Bokha stream was classified as 'fair'; commonly, the representing streams were comparatively active on meandering and accumulation; on the other hand, erosion was less active. As a result of the study for flora on this 3 streams, $Phaiaris\;arundinacfa\rightarrowPhragmites\;japonica\rightarrowPhragmites\;communis\rightarrowSalix\;koreensis\rightarrowFraxinus\;rhynchophylla\rightarrowRobinia\;pseudo-acacia-Acer$ ginnala communities were developed in order of being closest to the water shore. In case of benthic macroinvertebrates, Ephemera striga ta Eaton and Cajopteryx atrata Selys, usually inhabited in the uncontaminated water, were investigated as common species. Besides, Limnodrilus gotoi Hatai and Family Chironomidae sp. 1 were the common dominant benthic macroinvertebrates.

This study classified and analyzed the assignments for the Hanbok skill contests between 1998 and 2017 so that the Korean hanbok can be properly passed down. this study proposes a variety of useful values for the Hanbok culture industry by providing basic data on various Hanbok making techniques to the Hanbok artisan. The results of the analysis of 39 assignments for the Hanbok skill contest are as follows. Firstly, The 20 assignments presented in the Local Skills Competitions consisted of 13 tasks (65%) in formal wear and 7 tasks (35%) in casual wear. Formal wear is mainly comprised of men's and children's wear (85.7%). There are Pungcha Baji, Sagusam, Kkachi Durumagi, Jeonbok & Bokgeon, Durumagi, and others on the formal wear of men'schildren's wear. In casual wear, 66.7% of women's wear such as scarves, skirts, jeogori, Hwejang Jeogori & chima were on the list of assignments. Secondly, All of the 19 assignments presented in the National Skills Competitions were in adult suits. Thirteen tasks (68.4%) were in formal wear and 6 tasks (31.6%) were in casual wear. Nine out of the 13 formal wear tasks (69.2%) were men's clothes. In 6 assignments of the casual wear, men's and women's clothes were presented three times each. Formal wear that had many assignments was the men's Chulik, which was presented three times in 2006, 2008 and 2016. Thirdly, Eighteen (90%) of the 20 assignments presented at the Local Skills Competitions were for lined clothes, and the remaining 2 (10%) were for unlined clothes. Eleven tasks (57.9%) out of the 19 assignments presented in the National Skills Competitions were for lined clothes, and 8 tasks (42.1%) were for unlined clothes.

This study explores experiences of male siblings without disability who are caring for their adult siblings with intellectual disability. To this end, in-depth interviews were conducted based on phenomenological qualitative research methods, and documents such as newspaper articles and broadcasting documentaries covering the care of participants were also used as materials. Data collection took place from August to October, 2017, and four brothers without disability participated in this study. Findings are presented as five themes: a sibling with a disability-centered life, living with complex emotions including emotional ambivalence, cautious life at all times, life to receive consolation, and life trying to achieve balance and harmony. Based on the results, political and practical considerations for brothers without disability and their families who support their adult siblings with intellectual disability are discussed. Implications for social workers are suggested.

This study empirically tests whether community participation has a positive effect on parenting efficacy among marriage immigrant women in South Korea. The 3rd wave of the Gyoenggi Education Welfare Panel data was used, which includes 396 marriage immigrant women residing in Gyoenggi Province. Findings of hierarchical multiple regression analyses suggested that higher Korean language proficiency, shorter duration of residency, lower parenting stress and more positive family environment were associated with higher parenting efficacy. Community participation level had a statistically significant and positive impact on parenting efficacy, even after controlling for other variables. The type of community activities did not have significant impact on parenting efficacy, except for children's school activities, which had a negative impact on parenting efficacy. Implications for social work practice are discussed.

Fine-grained sediments of the Han River and adjacent Kyonggi Bay have been studied using the powder x-ray diffractometer in order to study the distributional characteristics of clay minerals in the bottom and suspended sediments. The result of the XRD analyse shows that the major clay minerals in the lower Han River are composed of illite (57.1%), kaolinite (22.9%), and chlorite (19.6%) and that those of the Han River Estuary are composed of illite (67.2%), chlorite (16.5%), kaolinite 915.5%), and smectite (1.3%). The variation of mineral content shows distinct distributional characteristics depending on sedimentary environments. The illite content increases gradually approaching the Kyonggi Bay and kaolinite content decreases toward the sea within the range between 11% and 23%. The trend of chlorite is similar to that of kaolinite, the amount of which ranges between 14% and 19%. Smectite content is lower than 3%. Analysis of illite using peak-intensity ratio (001/002) indicates that two types of illites occur in the study area. Dioctahedral-type illite occurs as an indicator of the marine sediments. The illites distributed between the Kyonggi Bay and the Han River are mixtures of dioctahedral- and trioctahedral-types. This study indicates that the distribution of illite, kaolimite, and chlorite has been influenced mainly by the supply from the Han River and redistributed by estuarine circulation, such as tidal circulation and seasonal variation of river discharge. However, smectite is apparently supplied from other sources such as Yellow Sea or China. This study suggests that estuarine mixing system and seasonal variations of river discharge are the major factors controlling the distribution pattern of clay minerals in the study area.

This study aimed to create globally acceptable Hanbok-inspired work uniforms, by developing practical designs and providing useful resources for incorporating Hanbok characteristics into office attire. First, to establish the elements that the Hanbok work uniform should have, the definition and characteristics of service clothes and preferences for the process of modernization of traditional Hanbok were reviewed through a review of the preceding studies. For the Hanbok work uniform design, a total of 4 pieces, 2 for each male and female, were planned, a schematic diagram was created, and the design was modified after evaluation by fashion design experts. I made a pattern of the modified design with a CAD program, imported it into CLO 3D to produce a virtual costume, and confirmed the final design draft. Work uniform design has symbolism, functionality, and aesthetics as its characteristics. The functionality of the Hanbok work uniform designed in this study is suitable for the season, and it was designed to increase the efficiency of work when worn for a long time. The design was focused on the development of materials and patterns in consideration of comfort and activity. The esthetic nature of hanbok-inspired work clothes was intended to reveal details that could highlight the silhouette of the human body and reflect the beauty of hanbok.
