Purpose : Since hepatitis A virus almost is transmitted by fecal-to-oral route, individual and public sanitation affects the prevalence and ages of hepatitis A infection. We researched the positivity rate of hepatitis A antibody at Pohang to make the basic data for subclinical infection and vaccination schedule. Methods : From January 2004 to February 2005, a total of 603 patients who were admitted at Hangdong University Sunlin Hospital, Dongguk University Hospital, and Christianity Hospital without any hepatic disease and vaccination of hepatitis A were enrolled. IgG antibody to hepatitis A virus were measured by electrochemiluminescence immunoassay(ECLIA). Results : Among 603 patients, 523 patients were less than 15 year of age and 80 patients were in above 15 years. The prevalence rate was 19.3%(101/523) in pediatric group and 70.0%(56/80) in above 15 years. In detail, the prevalence rate was 73.2%(52/71) in 0~5 months, 14.9%(11/74) in 6~11 month, 8.9%(7/79) in 12~17 month, 7.3%(6/82) in 18~23 month, 5.5%(4/72) in 2~3 years, 12.1%(9/74) in 4~8 years, 16.9%(12/71) in 9~14 years, 52.5%(19/40) in 15~29 years, and 92.5%(37/40) in group aged over 30 years. The prevalence rates in male and female showed no significant differences. Conclusion : The prevalence rate of hepatitis A in the group of 4~8 years and 9~14 years at Pohang was lower comparing with previous reports of other cities in Korea. We can postulate that the sanitation of children living at Pohang is at least not bad than other cities. And for the prevalence rate of hepatitis A is increased after 3 years, we should recommend that the vaccination of hepatitis A may be finished until 3 years.

Objectives: Firefighters are known to be exposed to a variety of toxic substances, but little information is available on the exposure profile of firefighting activities. The aims of this study were to conduct exposure monitoring of toxic chemicals at fire scenes, to compare the concentrations of respective chemicals among firefighting tasks, and to assess the main factors influencing the concentrations of chemicals. Methods: Researchers performed sampling at firefighting scenes during four weeks in 2013. At the scene, we collected samples based on firefighters' own activities and examined the situation and scale of the accident. Collected samples were classified into three categories, including fire extinguishing and overhaul, and were analyzed in the laboratory according to respective analysis methods. Results: A total of fourteen fire activity events were surveyed: five fire extinguishing, six overhaul, and three fire investigations. Although no substance exceeded the ACGIH TLV, PAHs were detected in every sample. Naphthalene ranged from 0.24 to 279.13 mg/㎥ (median 49.6 mg/㎥) and benzo(a)pyrene was detected in one overhaul case at 10.85 ㎍/㎥. Benzene (0.01-12.2 ppm) was detected in every task and exceeded the ACGIH TLV. No significant difference in concentrations between tasks was shown. Conclusions: These results indicate that all firefighting tasks generated various hazardous combustion products, including possible carcinogens.

Purpose : Recent changes in the population structure of Korea, such as rapid decline in birth rate and exponential increase in old-aged people, prompted us to prepare a new health improvement program in children and adolescents. Methods : We reviewed current health screenings applied for children and adolescents in Korea and other developed countries. We collected and reviewed population-based data focused on mortality and morbidity, and other health-related statistical data. We generated problem lists in current systems and developed new principles. Results : Current health screening programs for children and adolescents were usually based on laboratory tests, such as blood tests, urinalysis, and radiologic tests. Almost all of these programs lacked evidence based on population data or controlled studies. In most developed countries, laboratory tests are used only very selectively, and they usually focus on primary prevention of diseases and health improvement using anticipatory guidance. In Korea, statistics on mortality and morbidity reveal that diseases related to lifestyle, such as obesity and metabolic syndrome, are increasing in all generations. Conclusion : We recommend a periodic health screening program with anticipatory guidance, which is focused on growth and developmental surveillance in infants and children. We no longer recommend old programs that are based on laboratory and radiologic examinations. School health screening programs should also be changed to meet current health issues, such as developing a healthier lifestyle to minimize risk behaviors—or example, good mental health, balanced nutrition, and more exercise.
Purpose: Sharing genetic information with family members is important for cancer awareness and prevention. The purpose of this study is to examine disclosure patterns of positive BRCA genetic test results to patients' relatives. Materials and Methods: A total of 106 probands who had positive BRCA genetic test results from the Korean Hereditary Breast Cancer Study participated in our study. Subjects were asked whether they had disclosed their genetic test results to first-, second-, and third-degree relatives. Univariate and multivariate analyses were used to identify factors associated with positive result sharing with close and distant relatives. Results: In total, 99 respondents (93.4%) informed at least one at-risk relative of the test result, and they all reported that they had disclosed their genetic test result to a first-degree relative. Communication of test results to other relatives occurred significantly less often, with only 31 of 99 subjects (31.3%) sharing their results with second- or third-degree relatives. In the results of univariate analyses, disclosure of genetic test results to more distant relatives was associated with marital status and months since post-test counseling. The reasons for communication were to provide information about the BRCArelated cancer risk and to recommend the genetic test. Conclusion: Most individuals with the BRCA mutation share their test results with first-degree family members; however, these results reach more distant relatives significantly less often. Therefore, it is necessary to encourage patients' communication with extended family members through systematic genetic counseling.
Purpose: In this study, we developed a new software tool for the analysis of renal scintigraphy which can be modified more easily by a user who needs to study new clinical applications, and the appropriateness of the results from our program was studied. Materials and Methods: The analysis tool was programmed with IDL5.2 and designed for use on a personal computer running Windows. For testing the developed tool and studying the appropriateness of the calculated glomerular filtration rate (GFR), $^{99m}Tc$-DTPA was administered to 10 adults in normal condition. In order to study the appropriateness of the calculated mean transit time (MTT), $^{99m}Tc-DTPA\;and\;^{99m}Tc-MAG3$ were administered to 11 adults in normal condition and 22 kidneys were analyzed. All the images were acquired with ORBITOR. the Siemens gamma camera. Results: With the developed tool, we could show dynamic renal images and time activity curve (TAC) in each ROI and calculate clinical parameters of renal function. The results calculated by the developed tool were not different statistically from the results obtained by the Siemens application program (Tmax: p=0.68, Relative Renal Function: p:1.0, GFR: p=0.25) and the developed program proved reasonable. The MTT calculation tool proved to be reasonable by the evaluation of the influence of hydration status on MTT. Conclusion: We have obtained reasonable clinical parameters for the evaluation of renal function with the software tool developed in this study. The developed tool could prove more practical than conventional, commercial programs.
Lots of cultures, memories, histories of the local life have disappeared. Some sectors of universities and religion have keep their records in manuscript archive only. On the other hand records of public sectors were at least able to be managed by the records management law. Citizen's groups and academic bounds were also roles to get public records strong. However can we just describe whole body with only public records? As records management law a record of private sector which has value of preserving can be managed under national protection. Yet establishment of local archive is not obligate. Only stressing on public records is like what dictatorial government acted in past years. It is what we ignore diversity and request of community. We need to move our view that we have focused on public and central sectors to private and local sectors. Local records management based on locality could help to complete the entire puzzle. The way complete the puzzle is various and wide spheres including from cultural space to being extinct village. Locality is defined as the property in certain area or distinctiveness of locals. Establishing production strategies is as important as collecting records produced over the past years for local archiving. Local archiving has to be regionally conducted in phase. Moreover common wealth and recognition of communities are reflected in the acquisition process. In next to archiving local organizations and private records according to collection policy, methodology on local archiving needs for archive management and use in various public and private fields. This methodology could be possible by building a local archive networking tool. It is true that Local archiving is not familiar and clear yet. If we can turn the effort for public records we have made to endeavor for private sectors, we might expect big fruits in private sectors. We easily emphasis on globalization or internationalization, our daily lives start on our villages. Setting aside our small communities, such a puzzle of the whole would never be completed. This is good time to begin finding lost puzzle for future. The key that can find lost puzzles be held in archiving localities.
The purpose of this study is to examine the mediating effects of resilience in the relationship between parent support and career decision level of specialization technical high school students and to find out ways to improve the level of desirable career guidance and counseling. The research questions are as follows: First, what is the level of parent support, career decision level, and resilience of special technical high school students? Second, what is the relationship between parent support, career decision level and resilience of high school students? Third, the resilience of resilience plays a mediating role in the relationship between parent support and career decision level of special technical high school students. In order to achieve the purpose of the study, the theoretical background related to parent support, career decision level, and resilience of special technical high school students was investigated and the test tool was produced. The results of the study are as follows. Parental support, career decision level, and resilience were highly correlated. There was a significant correlation between parent support and career decision level, resilience and career decision level, and emotional support and verbal encouragement were more than 50% of the career decision level. In terms of mediating effect, the effect of parent support on career decision level was found to be partially mediated by overall resilience and sub - factors such as control, positive, and sociality. Therefore, in order to improve the quality of career guidance counseling, a program linked to the school and the home should be conducted considering both domestic factors and internal factors.
This study aims to evaluate Person Centered Care practice and characteristics of care services in Korean long-term care facilities using Dementia Care Mapping as a tool. DCM, systematic observational evaluation tool for measuring dementia patients' QOL, was transformed into self-report rating scale. The process of transforming DCM into a scale of 34 items involves operationalization of DCM concepts and it's adaptation into Korean long-term care practices. Review by research team of Bradford university was added to maintain DCM concept and meaning in this scale. The scale with Cronbach alpha of .88 was surveyed on 343 care workers. Survey result shows PCC value practiced by them is 3.77(of 5 likert scale) and values on each categories of PCC reveal the characteristics of care in Korean facilities; attachment(4.02), comfort(3.95), inclusion(3.89), identity(3.67) and occupation(3.41). Dementia care in Korean facilities focuses on recipients'safety, comfort but lacks individualistic care and the meaningful and fulfilling occupation for patients. Looking at the organizational and individual factors influencing DCM values, the small facilities showed higher PCC values and there are no significant difference in PCC values between public and private facilities. Managers and care workers with career of 1~2 years showed higher PCC values compared to other career ranks and lengthes. This study suggests care practice should be centered on personhood of patients in long-term care facilities, for which introduction of unit care and education of PCC for service providers including support personnel are needed. DCM and Korean DCM scale developed in this study are suggested for the PCC-based assessment on care quality.

Due to COVID-19, the external activities of urban residents have greatly shrunk, causing a lot of damage to the commercial district, such as a decrease in population and sales. The downturn in commercial districts means the collapse of the infrastructure of the national economy, and can have serious side effects on the local economy and individual lives. Therefore, it is necessary to look at the alley commercial area, which is closely related to the national local economy, and pay attention to the damage and stagnation of the alley commercial area where small business owners are concentrated. The purpose of this study is to classify alley commercial districts into growth commercial districts and decline commercial districts by using commercial sales time series data and DTW time series group analysis for the pre- and post-COVID-19 period. The main findings of the study are as follows. First, using the time series data on commercial sales before and after COVID-19, the alley commercial districts were divided into growth commercial districts and decline commercial districts, and it was confirmed that the distribution of growth commercial districts and decline commercial districts was regionally different. Therefore, it is necessary to actively manage commercial districts in areas where many declining commercial districts are distributed, and it is required to prepare policies for each region in consideration of the spatial distribution of declining commercial districts. Second, during the COVID-19 period, face-to-face essential industries, density of guest facilities, and population density negatively affected the sustainability of commercial districts, which is the opposite of previous studies. This is the result of empirically confirming the specificity of the COVID-19 period and the negative effects of the integrated economy, and can be used as basic data for effective commercial district management and policy preparation in the event of a national disaster in the future. Third, the characteristics of the background of the commercial district had a significant effect on the sustainability of the commercial district, and the negative effect of the attracting facilities inducing population concentration in the background area was found. This suggests that it is necessary to consider the characteristics of the background as well as the inside of the commercial district when establishing policies to revitalize the commercial district and support small business owners in a national disaster situation.
This study aims to provide basic data to reduce the incidence of radiation dermatitis and improve patient satisfaction by investigating the management status and satisfaction level of radiation dermatitis in patients undergoing radiation therapy. From October 28, 2022, to April 4, 2023, a survey was conducted on 137 breast cancer patients who received radiation therapy at G Hospital in Busan. The Radiation Therapy Oncology Group (RTOG) cutaneous acute radiotherapy toxicity score was used as the standard for measuring skin reactions, and the association between cancer stage and RTOG was analyzed. SPSS program (ver. 18.0) was used for statistical analysis. The frequency of radiation dermatitis occurrence was relatively low, with 73% in the RTOG 0-1 group and 27% in the 2-3 group. Patient satisfaction after radiation therapy varied significantly depending on the RTOG group, with lower levels of dermatitis resulting in higher satisfaction and higher levels resulting in dissatisfaction (p=0.001). Although there was no statistically significant difference in RTOG group and skin satisfaction depending on the frequency of aloe mist use (p=0.065), the group that used it 1-2 times a day (69.3%) showed a higher satisfaction level. The perceived effects of aloe mist use were statistically significant for decreasing heat sensation (p=0.001), pain (p=0.033), itching (p=0.001), and psychological stability (p=0.027), especially in the higher RTOG groups. Additionally, as cancer stage increased, the severity of radiation dermatitis also increased, which was statistically significant (p=0.001). In conclusion, radiation dermatitis is the most common side effect of radiation therapy, and it can appear in various forms depending on individual skin sensitivity and external factors during treatment. Adequate education before treatment and the use of MD Cream and aloe vera mist are recommended to reduce the incidence and manage radiation dermatitis effectively.
