On the basis of the study intended to research by cross-sectional study keeped pace with semi-longitudinal study the growth accelerating phenomena that MGA(Maximum Growth Age) in teenager's body height. The duration of study is from Oct. 1st. 1991 to September 30 1992 and the data are analysed through computer. The body height and MGA of Koreans who had been for during the period from 1898 to 1973 proved transition of the growth accelerating phenomena by research data reported between 1913 and 1990. The results are as follows: 1. Maximum Growth Age The MGA's in body height of male are respectively the age 15.024 in 1913, 14.28 in 1940, 13.65 in 1959, 13.86 in 1967, 12.52 in 1983, 11.39 in 1987, 12.36 in 1990, while those of female are the age of 12.0 in 1940, 12.36 in 1959, 10.45 in 1969, 11.15 in 1985, 10.27 in 1988, 10.23 in 1990 ; these data show that the MGA of the Korean has been getting younger. 2. The correlation of the MGA's in body height are as below ; Male ; r = -0.448(p<0.01) Female ; r = -0.404(p<0.05) 3. The equation of linear regression of MGA's in body height are as below ; Male ; Y(MGA) = -0.0316X(the year)+75.297 Female ; Y(MGA) = -0.035X(the year)+79.986 4. The MGA's in body height are shown in Table 3. 5. From the transition of the growth accelerating phenomena, we can compute the fact that the MGA's has been getting younger by 0.3 year per 10 years. 6. The future growth accelerating phenomena in body height, the MGA's of male are respectively the age 12.25 in 1995, 12.09 in 2000, 11.94 in 2005, 11.78 in 2010, while those of female are the age of 10.16 in 1995, 9.98 in 2000, 9.81 in 2005, 9.64 in 2010, these data show that the MGA of female are more younger than that of male.

Purpose: The purpose of this research was to evaluate the application of the Problem-Based Learning(PBL) in nursing with regard to the learning process and learning outcomes. Method: PBL modules were provided to the students so that they could identify the nursing problems related to nutrition, regulation, and elimination, and implement appropriate nursing interventions according to the problems. PBL was also used to develop ability to use self-evaluation for nursing intervention outcomes. The modules were developed by the authors for the course, Nursing 1(3 credits) at Y university, and used during one semester, March to June 2003. Evaluation of the learning process and learning outcomes was done by self-report questionnaires and a semi-structured self -report developed by the authors. Result: The PBL evaluation included role of the facilitators, group work process, and self-directed learning attitude. The students evaluated the facilitator's role positively in fostering positive interactions and cooperative study among students and stimulating students to apply various problem-solving strategies. Students evaluated their own group work performances as a good opportunity to improve their group work participation, contribution, cooperation, and leadership through the PBL session. Their responsibility for their own learning and develop self-directed learning attitudes to connect present learning to long-term goals. Conclusion: Critical thinking, problem solving skills, self-directed learning and group work accomplishments in undergraduate student nurses were fostered and improved through the PBL program.
The purpose of this study is to identify the characteristics and influencing factors of the attachment-oriented caretaking behaviors among the mothers with infants. The total number of 204 mothers participated in this survey as subjects. They all were breast-feeding mothers who had their infants joining in the semi-final round of a healthy breast-feeding infant contest. The data were collected from July 14, 1999 to May 19, 2000. And the data were analyzed by SPSSWIN 10.0 version. The result of this study was as follows ; 1. The mean ages of the subjects were 29.5 and 95.6 percents of them were no-job housewives. 57.8% of them were normal delivery. And the mean months of the infants were 6.2 and the male infants were 57.4%. The first born babies were 62.3%. 2. The mothers are affirmative enough with their attachment-oriented caretaking behaviors (the total mean was $3.58{\pm}.631$). In general, the mothers showed very attachment-oriented caretaking behaviors, but the points that indicated "recording the development characteristics of the infant and discussing them with husband" were very low(score $2.79{\pm}.982$). 3. There are Significant differences in caretaking behaviors of the mothers according to their ages(F=3.497, p=.017), the degree of morning sickness(F=2.633, p=.050) and the birth order of their infants(F=4.854, p=.003). The older mothers and mothers who experienced the less morning sickness showed the higher scores of the attachment-oriented behaviors. The mothers who experienced the more deliveries showed the higher scores of the attachment-oriented behaviors. Accordingly, the above result suggests that the systematic and practical nursing intervention to encourage the attachment-oriented behaviors is essential to the younger, primipara mother.
Purpose: The world saw a shift into a new society consequent to the coronavirus disease 2019 (COVID-19), which made home quarantine mandatory for a person in close contact with those who tested positive. For children, however, home quarantine was not limited only to themselves but parents, especially mothers were involved and required to quarantine. This qualitative study aims to explore and understand mothers' experience and their related psychosocial issues while caring for their school-aged children in Korea, who had to home quarantine after coming in close contact with COVID-19 positive individuals. Methods: Data were collected from October 2020 to January 2021 via in-depth, semi-structured interviews with nine mothers of children who had to home quarantine. Interviews were conducted face-to-face in an independent space near the participant's home or workplace (n=5) or via online platforms or telephone (n=4). The data were analyzed using thematic analysis through several iterative team meetings. Results: Thematic analysis revealed the following four themes: "Unable to be relieved due to uncertain situations surrounding me," "Blame and hurt toward me, others, and one another," "Pulling myself together for my children in my broken daily life," and "Changes in the meaning of life amid COVID-19." Conclusion: The narratives show that mothers experienced psychosocial difficulties while caring for their children during home quarantine. It is necessary to reduce the social stigma toward individuals in home quarantine and establish policies to ensure work-family compatibility for such mothers.

Objectives: This study was conducted to identify the demand and willingness to pay for oral hygiene services among elderly people with long-term care insurance. Methods: Our study was a cross-sectional analysis. Subjects comprised 126 elderly individuals from long-term home-care centers. A total of 28 centers were selected through convenience sampling from among 78 centers in ${\bigcirc}{\bigcirc}$. For analysis, semi-structured questionnaires that required about 20-30 minutes to complete were used. Analysis was performed using SPSS 23.0 software. Results: The overall demand for oral hygiene services was 44.4%, and willingness to pay was 31.0%. Thirty-three people (58.9%) of elderly those who have demand for an oral hygiene service were willing to pay for the service, and 64 people (91.4%) who did not have a demand were not willing to pay for it. Among those with partial dependence on brushing, 65.6% had demand for oral hygiene services and 50.0% were willing to pay costs. Among basic livelihood beneficiaries, 69.6% were willing to pay for oral hygiene services; general subjects and relievers were less willing to pay. Conclusions: The overall demand for oral hygiene services among elderly people was 44.4%, and the willingness to pay was as low as 31.0%.
Purpose: This study investigated the patient safety culture (PSC), the perception of importance on patient safety management (PIPSM) and the patient safety management activities (PSMA) of care workers in nursing homes. This was a descriptive study that attempted to provide basic data for the patient safety education program of care workers. Methods: Data were collected using questionnaires and interviews from July 1 to 31 in 2020. One hundred and seventy-four care workers participated in quantitative research. The collected data were analyzed by the SPSS/WIN 25.0 program using descriptive statistics, t-test, ANOVA, Bonferroni, and Pearson's correlation. The qualitative data were collected through semi-structured, audio-recorded interviews with six representatives and six care workers from six nursing homes. Content analysis was performed to analyze the data. Results: Positive correlations were observed between PSC and PIPSM, and between PIPSM and PIPSM. Care workers' experience in patient safety management was in the following six categories: "Safety accident risk factors", "Type of safety accidents", "How to prevent safety accidents", "Effective safety management education", "Emphasis on occupational ethics of care workers", and "Needs for standard protocol" Conclusion: These findings indicate that considering the care workers' age and facility size, nurses should enhance patient safety education for care workers and establish a management activity system.
The New Silver Generation, which includes retired baby boomers, is eschewing traditional lifestyles, remaining socially and economically active, and striving to enjoy their lives. It is necessary to understand the preferences, sensibilities, and fashion propensities of such individuals. Thus, this study analyzed the New Silver Generation's fashion color preferences and proposed fashion color scheme guidelines that could be used in the fashion industry. First, surveys were conducted in people of the New Silver Generation aged from 55 to 65 years. The survey questions included the following: fashion color preferences, fashion sensibility and taste preferences, fashion interests, lifestyle, and demographic background. Second, the survey was conducted to identify differences in color preferences based on respondents' fashion interests and lifestyles. Next, to compose color palettes for the survey, 45 colors from the Munsell color system were chosen at random. The major research results were as follows: It was shown that socializing- and health-preferring individuals wore achromatic color, leisure-preferring individuals wore P color, and self-preferring individuals wore B color. The commonly worn colors were achromatic colors. After the age of 55 years, health- and leisure-preferring individuals often wore R color and RP color, respectively. Thus, this study proposed a color scheme arrangement that used achromatic colors, such as black and white, as the main colors list for the four lifestyle types.
Anti-cholinesterase (ChE)s are commonly prescribed as the symptomatic treatment of Alzheimer's disease. They are applied to prevent the breakdown of neurotransmitter acetylcholine (ACh) that bind to muscarinic and nicotinic receptors in the synaptic cleft. Seaweeds are one of the richest sources of bioactive compounds for both nutraceuticals and pharmacognosy applications. This study aimed to determine the anti-ChEs activity of Gracilaria manilaensis, one of the red seaweeds notables for its economic importance as food and raw materials for agar production. Methanol extracts (GMM) of G. manilaensis were prepared through maceration, and further purified with column chromatography into a semi-pure fraction. Ellman assay was carried out to determine the anti-acetylcholinesterase (AChE) and anti-butyrylcholinesterase (BuChE) activities of extracts and fractions. Lineweaver-Burk plot analysis was carried out to determine the inhibition kinetic of potent extract and fraction. Major compound(s) from the most potent fraction was determined by liquid chromatography-mass spectrometry (LCMS). GMM and fraction G (GMMG) showed significant inhibitory activity AChE with EC50 of 2.6 mg/mL and 2.3 mg/mL respectively. GMM and GMMG exhibit mixed-inhibition and uncompetitive inhibition respectively against AChE. GMMG possesses neuroprotective compounds such as cynerine A, graveolinine, militarinone A, eplerenone and curumenol. These findings showed a promising insight of G. manilaensis to be served as a nutraceutical for neuronal health care in the future.

Background: A nationwide outbreak of foot-and-mouth disease (FMD) in South Korea caused massive economic losses in 2010. Since then, the Animal and Plant Quarantine Agency (QIA) has enhanced disinfection systems regarding livestock to prevent horizontal transmission of FMD and Avian influenza (AI). Although the amount of disinfectant used continues to increase, cases of FMD and AI have been occurring annually in Korea, except 2012 and 2013. Objectives: This study measured the concentration of the disinfectant to determine why it failed to remove the horizontal transmission despite increased disinfectant use. Methods: Surveys were conducted from February to May 2017, collecting 348 samples from disinfection systems. The samples were analyzed using the Standards of Animal Health Products analysis methods from QIA. Results: Twenty-three facilities used inappropriate or non-approved disinfectants. Nearly all sampled livestock farms and facilities-93.9%-did not properly adjust the disinfectant concentration. The percentage using low concentrations, or where no effective substance was detected, was 46.9%. Furthermore, 13 samples from the official disinfection station did not use effective disinfectant, and-among 72 samples from the disinfection station-88.89% were considered inappropriate concentration, according to the foot-and-mouth disease virus guidelines; considering the AIV guideline, 73.61% were inappropriate concentrations. Inappropriate concentration samples on automatic (90.00%) and semi-automatic (90.90%) disinfection systems showed no significant difference from manual methods (88.24%). Despite this study being conducted during the crisis level, most disinfectants were used inappropriately. Conclusions: This may partially explain why horizontal transmission of FMD and AI cannot be effectively prevented despite extensive disinfectant use.
