Taean county region has been economically lagged behind compared with other areas in Chungnam Province mainly due to disadvantages of the location such as traffic accessibility, social infrastructure and industrial complex. However, recently Taean region has been emerged as newly prospective area because west coastal highway will be constructed to connect Seoul urban area to famous beach sites, recreational facilities along the seaside of Taean county, where International Flower Exhibition will also be held in Anmyon Island for the year of 2002. This Paper aims to explore how International Flower Exhibition is contributing to the development of local economy of Taean County area and to suggest the strategies for the development of this area through promoting spread effects of these international events. It is estimated that although there will be loss of 32,987 thousands won during the period of international flower festival based on the cash flow analysis, long run profits would be 108 trillion won, when calculating indirect benefits derived from the sight seeing, flower sales and other incomes from various activities. In order to maximize post benefits of international flower event, it is suggested that Taean county should pursue the strategies for specializing in cultural events such as family recreational events, beach festival and traditional cultural events, improving the social infrastructure and promoting the local industry such as flower, tourism and advanced technological enterprises.

The purpose of this study was to provide information to prevent and manage the risk factors of adolescent health behavior by identifying the relationship between smartphone use and the intake of sugar-sweetened beverages of Korean adolescents. Data from the 2017 Korean Youth Risk Behavior Survey of 54,603 adolescents was used for this study. The study examined the variables related to general characteristics, smartphone use, and intake of sugar-sweetened beverages. Complex sample analysis was done by performing multivariate logistic regression analysis. Smartphone usage time (aOR = 2.19, 95%CI = 2.05-2.34) and smartphone use for communication (aOR = 1.51, 95%CI = 1.43-1.60) were associated with three or more times per week of SODA beverage intake. In addition, adolescents who experienced conflicts with family were associated with SODA beverage intake (aOR = 1.42, 95%CI = 1.33-1.51), conflict with friends was associated with sweet beverage intake (aOR = 1.39, 95%CI = 1.30-1.49), and study problems were associated with SODA beverage intake (aOR = 1.79, 95%CI = 1.54-2.07). Therefore, controlling the use of Smartphones in schools and homes and creating an environment in which communication skills can be learned can help adolescents reduce the intake of sugar-sweetened beverages. Positive relationships with family and friends, and appropriate management of academic stress can help reduce inappropriate health behaviors associated with smartphone use by adolescents.

This study was conducted to identify the factors affecting breastfeeding in adult women based on socio-demographic and health-related characteristics using the results of KNHANES VII-3. The data was analyzed by applying weights, using the complex sample analysis method of the SPSS Win 22.0 program. Breastfeeding was influenced significantly by age, education level, and the current smoking status. Women in the age group of 30-39 years had a breastfeeding rate that was 3.06 times higher than 19-29 year old women. Also, the breastfeeding rates for women with an education level under elementary school were 4.70 times higher than those with a college degree or higher education level and non-smokers and ex-smokers had levels 2.51 times higher than smokers. Therefore, for mothers under the age of 30, education on breastfeeding should be further strengthened. For mothers over 40 years old, lactation support to increase the milk supply should be provided as well as assistance toward care for other children in the family. Also, better-educated mothers will need to learn effective breastfeeding methods in limited environments such as work-life, and a social atmosphere needs to be established that is considerate to lactating women. Furthermore, education related to pregnancy and lactation should be provided for use in smoking cessation programs for female smokers.

Hyaluronidases are a family of enzymes that catalyse the breakdown of hyaluronic acid, which is abundant in the extracellular matrix and cumulus oocyte complex. To investigate the activity of recombinant bovine sperm hyaluronidase 1 (SPAM1) and determine the effect of the Asn-X-Ser/Thr motif on its activity, the bovine SPAM1 open reading frame was cloned into the mammalian expression vector pCXN2 and then transfected to the HEK293 cell line. Expression of recombinant bovine hyaluronidase was estimated using a hyaluronidase activity assay with gel electrophoresis. Recombinant hyaluronidase could resolve highly polymeric hyaluronic acid and also caused dispersal of the cumulus cell layer. Comparative analysis with respect to enzyme activity was carried out for the glycosylated and deglycosylated bovine sperm hyaluronidase by N-glycosidase F treatment. Finally, mutagenesis analysis revealed that among the five potential N-linked glycosylation sites, only three contributed to significant inhibition of hyaluronic activity. Recombinant bovine SPAM1 has hyaluronan degradation and cumulus oocyte complex dispersion ability, and the N-linked oligosaccharides are important for enzyme activity, providing a foundation for the commercialization of hyaluronidase.

α-Galactosidase is a debranching enzyme widely used in the food, feed, paper, and pharmaceuticals industries and plays an important role in hemicellulose degradation. Here, T26, an aerobic bacterial strain with thermostable α-galactosidase activity, was isolated from laboratory-preserved lignocellulolytic microbial consortium TMC7, and identified as Parageobacillus thermoglucosidasius. The α-galactosidase, called T26GAL and derived from the T26 culture supernatant, exhibited a maximum enzyme activity of 0.4976 IU/ml when cultured at 60℃ and 180 rpm for 2 days. Bioinformatics analysis revealed that the α-galactosidase T26GAL belongs to the GH36 family. Subsequently, the pET-26 vector was used for the heterologous expression of the T26 α-galactosidase gene in Escherichia coli BL21 (DE3). The optimum pH for α-galactosidase T26GAL was determined to be 8.0, while the optimum temperature was 60℃. In addition, T26GAL demonstrated a remarkable thermostability with more than 93% enzyme activity, even at a high temperature of 90℃. Furthermore, Ca²⁺ and Mg²⁺ promoted the activity of T26GAL while Zn²⁺ and Cu²⁺ inhibited it. The substrate specificity studies revealed that T26GAL efficiently degraded raffinose, stachyose, and guar gum, but not locust bean gum. This study thus facilitated the discovery of an effective heat-resistant α-galactosidase with potent industrial application. Meanwhile, as part of our research on lignocellulose degradation by a microbial consortium, the present work provides an important basis for encouraging further investigation into this enzyme complex.

A case study has been conducted on the changes in the identity and agency of international marriage migrant women who experienced a shift from a immigrant worker to a foreign spouse and a Korean citizen. The life histories of the eight female migrants living in Gumi area, a representative inland industrial complex in Korea, have been investigated by in-depth interview. The aim is to examine how the female migrants reconstruct and interpret their lives. The results reveal that the identy of a female migrant is flexible depending on her social positionality. The identities established from the past experiences in their native countries have been changed by their situations and conditions in Korea. The female immigrants recognize that their problems have been an important issue both in government policy and mass media. However, the female migrants express a strong revolt against the fact that they are considered as underclass victims or innocent people from underdeveloped countries. This implies their ambivalence toward international marriage that they selected subjectively. There is a finding to show a new possibility; the Transnational Marriage & Family Support Center supported by Government may provide a good ground for the female migrants to be a active group agent. The results illustrate that the international marriage migrant women could not be classified into a single group as wives. Called for are diverse researches reflecting the complex situations of migrant women.

The purpose of this study is to investigate factors related to substance use focusing on the sexual experiences and risky sexual behaviors among Korean adolescents. This study conducted with a secondary data analysis using the Seventh Korea Youth Risk Behavior Web-based Survey 2011 in South Korea. The study participants selected 75,643 Korean adolescents who were recruited anonymously through national web-based survey. Data were analyzed using descriptive statistics, rao-Scott ${\chi}^2$, and logistic regressions considering complex samples. Results indicated that substance use was significantly associated with sexual experiences such as sexual intercourse with the opposite sex (adjusted OR=5.691; 95% CI=4.223-7.670), sexual intercourse with the same sex (adjusted OR=21.180; 95% CI=14.704-30.507) and risky sexual behaviors such as sexual assaults (adjusted OR=9.936; 95% CI=7.217-13.680), date rape (adjusted OR=16.979; 95% CI=11.648-24.751), sexual intercourse after drinking (adjusted OR=6.564; 95% CI=3.986-10.810), unexpected pregnancies (adjusted OR=18.628; 95% CI=8.476-40.936), and sexually transmitted diseases (adjusted OR=21.872; 95% CI=13.920-34.367) in Korean adolescents. Findings of this study show that adolescents who use substances are more likely to engage in risky sexual behaviors. Therefore, intervention program should be designed to consider both substance use and sexual problems and to include the effective approaches at the family and school level.

This study aimed to identify factors associated with metabolic abnormalities in non-obese and obese postmenopausal women based on biopsychosocial model. Secondary data analysis was conducted using data from 5,335 postmenopausal women who participated in the Korean National Health and Nutrition Examination Survey (2015-2021). According to logistic analysis with applying a complex simple analysis in SPSS 26.0, biomedical (increased age; a family history of hypertension, type 2 diabetes, dyslipidemia, and cardiovascular diseases) and biosocial factors (low educational level) were associated with 1-2 metabolic abnormalities and metabolic syndrome, regardless of adiposity. Additionally, low familial socioeconomic status and prolonged sedentary behaviors were the biosocial and psychosocial factors associated with metabolic syndrome regardless of adiposity. Finally, insufficient physical activity was associated with metabolic syndrome in obese postmenopausal women. Based on these results, tailored strategies should be developed considering the significant factors associated with metabolic abnormalities and adiposity in postmenopausal women.

As the proportion of women's participation in economic activities is rising, the increase of husband and wife both working and nuclear families makes children up-bringing a social problem. But many families have difficulties by the shortage of day nurseries which can solve it. As we can see in the research, the most urgent problem is the extension of nurseries in quantity. In Taegu, since it became a wide-area city, there are 473 nurseries. But in the respect of distribution, only less than 10% of Dongs have more than 7 nurseries and more than 90% of Dongs have less than 7 nurseries. Consequently nurseries are extremely insufficient. Moreover 29 Dongs don't have any nurseries at all and they take 18.6% of Dongs. The second problem is the unbalanced distribution of nurseries. West and north ward which are industrial complex and swarmed with low-income families, and Tal-sung county which is recently included in the wide-area city keenly need the establishment of nurseries. Besides, Bi-san 1 Dong and Non-gong which have only $1{\sim}2$ nurseries though they have high proportion of children and women who can be pregnant are also the areas which take precedence of nursery establishment. The third problem is that government support must be increased in the areas which have many small, petty and profit-making private nurseries so that good quality teachers can make breeding activities in nice facilities and environment. In materials which are obtained by the interviews with publich servants in charge of family welfare in some ward offices. Young and unexperienced persons who aquired certificate of qualification take day-nursery permits and run nurseries only a few months. and if the profits are insufficient, they sell the nurseries for premiums to third persons who are not qualified. Then the third managers only think of profits without thought of good quality childcare. As the result, the nurseries become asylums not nurseries. That is why the conditions of nursery establishment must be restricted to suitable scale and experienced persons. The fourth problem is that the nurseries in work places are extremely insufficient. The women who have jobs have many things to do before they go to work such as preparing meals and leaving children in the care of someone. Hence the childcare problem of working women must be solved. In nuclear families, childcare is the most serious problem for working women. The fifth one is the reduction of childcare expenses. Women must sacrifice themselves a lot to make social activities. To say nothing of physical and mental burden, they have to spend much of their salaries on childcare. And yet they don't take the benefit of good quality childcare. For the participation of women in public affairs, society must support the childcare problem to have then be devoted to their jobs without worries about their children. Therefore Taegu wide-area city must select west, north ward which are industrial complex and the low-income swarmed area before everything and establish many national, public and corporate nurseries which cost less expenses.
