This study investigated how many and which articles readers read in daily newspapers. Distinguished from previous research that measured readers' perception of their reading habits, this study picked up readers who read the newspaper in the morning, showed them every article in the newspaper, and asked them whether they read each article. This method enhanced the accuracy of measuring subjects‘ reading behavior. According to the results, 6.2% of the readers read at least half of the articles of the general section in the newspaper. Fewer readers went over the economic section of the newspaper. It was 4.1% of the readers. There were only 1.1% of readers who did not read any article of the general section, but the rate soared to 26.5% for the economic section. Many newspaper readers did not skip the first five pages of the newspaper, however the highest readership pages were found in the national coverage located in the middle of the general section. On the other hand, few readers read the articles on pages covering culture, international issues, and people. Readership of the top stories showed some unexpected results. The top stories of national coverage located in the middle of the general section were read by more readers than the top stories of the front pages. This study also investigated the difference between young and old readers. The readers of twenties and thirties did not read as many top stories on major pages and editorials as the readers of forties and older.

This article attempts to restructurize the current arguments on how to change the method of financing child care programme, which is currently under discussion in Korea. There has been a series of changes in Korean child care policy, such as the amendment of Child Care Act, the transition of its responsible administrations, adoption the child care policy as a national agenda. In these changes, new needs for child care financing method comes out with a new direction of child care policy and a plan of expansion of finances. That's the transition from 'facility-centered subsidy' to 'child-centered subsidy'. This article redefine it as the arguments about 'supply-side subsidy' vs. 'demand-side subsidy'. To analyse the different traits of two branches of arguments, this article reviews the social welfare models, and has come to the conclusion that the Burchardt's model is appropriate to explain the financing debates. Thus, the analysis the traits of the two perspectives is based on three dimensions i. e. service provision, financing and decision making according to the Burchardt's model. This also examines how the two sides is connected to the discussion of publicity and quality improvement of child care service. Through this approaches and analysis, this helps us restructurize the debates on the method of financing from the present superficial arguments.

This article is aimed at exploring what factors influence the perception change of the consumers for the cultural heritage values in the case of the cultural heritage policy program entitled with the cultural heritage Yahaeng. The consumers is considered as a key factor in the value creation system of the cultural heritage Yahaeng. It is necessary that the priority of the cultural heritage Yahaeng should be shifted from the supplies to the consumers. The consumer-based model of cultural heritage utilization is used as a theoretical framework. This study examines the influence of cultural heritage authenticity, cultural motivation, management system, loyalty on the perception change of the consumers for the cultural heritage values. This study is empirically examined by the means of a survey conducted on 205 visitors in the case of the Suncheon Yahaeng. The results indicate that the cultural heritage Yahaeng positively influences the perception change of the consumers for the cultural heritage values. In addition, the results indicate that cultural heritage authenticity is the most important factor which positively influences the perception change of the consumers for the cultural heritage values. In addition, the results indicate that cultural motivation positively influences on the perception change of the consumer for the cultural heritage values through the mediating variable of the loyalty. In line with its results, the article recommends that the significance based management system, evaluation system focused on the perception of the consumers for the cultural heritage should be established in the future. The article concludes that the local residents should be importantly considered as consumers and the collaborative partners in the cultural heritage Yahaeng.

The survey was carried out with a random sample of adults living in Busan and Gyeongnam. The collected material is used by the SPSS version 12.0. The frequency, percentage, examination were applied for studying. We separated the group of safety, general management, real hair management according to characteristic about scarp and hair problems. There is highly understanding about the hair problem that if someone has really sensitive scalp or who has dandruff or who has thin hair or who has someone has hair losing problem in their family. Usually, the group has highly understanding of hair problem, they consult about their hair and scalp with expert. They have a really good attention about the mass media(TV, Internet, Newspaper, Magazine) for scalp and hair health. They reduce using hair products. They always read hair product brochure first and use it. They don't eat fast food frequently. The survey has shown high levels of article. Now the research showed us that s have a strict connection between self-recognition and scalp treatments. That means someone has understanding hair problem then start treatment first.

Background: We earlier used PCR-dHPLC for mutation analysis of BRCA1 and BRCA2. In this article we report application of targeted resequencing of 30 genes involved in hereditary cancers. Materials and Methods: A total of 91 patient samples were analysed using a panel of 30 genes in the Illumina HiScan SQ system. CLCBio was used for mapping reads to the reference sequences as well as for quality-based variant detection. All the deleterious mutations were then reconfirmed using Sanger sequencing. Kaplan Meier analysis was conducted to assess the effect of deleterious mutations on disease free and overall survival. Results: Seventy four of the 91 samples had been run earlier using the PCR-dHPLC and no deleterious mutations had been detected while 17 samples were tested for the first time. A total of 24 deleterious mutations were detected, 11 in BRCA1, 4 in BRCA2, 5 in p53, one each in RAD50, RAD52, ATM and TP53BP1. Some 19 deleterious mutations were seen in patients who had been tested earlier with PCR-dHPLC [19/74] and 5/17 in the samples tested for the first time, Together with our earlier detected 21 deleterious mutations in BRCA1 and BRCA2, we now had 45 mutations in 44 patients. BRCA1c.68_69delAG;p.Glu23ValfsX16 mutation was the most common, seen in 10/44 patients. Kaplan Meier survival analysis did not show any difference in disease free and overall survival in the patients with and without deleterious mutations. Conclusions: The NGS platform is more sensitive and cost effective in detecting mutations in genes involved in hereditary breast and/or ovarian cancers.

It becomes possible to conserve and manage the records also which the Head of Archives(National Archives of Korea) designated at the Records Center(Special Records Center) based on the amendment of the Article 30 of the Enforcement Ordinance of the Public Records Management Act on Nov. 2014. However, the right for the decision for above is given to the National Archives of Korea and other operation and preservation management system different with existing ones such as that relevant Records Centers prepare preservation countermeasure of subject for the amendment and additionally perform all sorts of works about the management should be prepared when the amendment treatment is executed. However, there is only the contents about the change of the preservation place is regulated in the Enforcement Ordinance of the Public Records Management Act and no legal basis to support the repositories for these change, so additional improvement is necessary. In this paper, present condition of preservation place change of the National Archives of Korea and the operation condition of relative records centers and suggest the supplementary and improving items with the Public Records Management Act.

This article is experimentally to investigate thermal-flow characteristics of the magnetic fluid for concentric annuli under externally fixed magnetic fields using visualization technique. Temperatures of the inner tube and outer tube in the tested concentric annuli were constantly maintained at both $30^{\circ}C$ and $25^{\circ}C$ and the middle tube was filled with the magnetic fluid. Magnetic field was uniformly applied using 4 permanent magnets at 4 directions of the concentric annuli. As a result, the thermal-flow characteristics of the magnetic fluid for concentric annuli could be controlled by directions of the external magnetic fields.

Fluid pumps in chemical processes are typically driven by electric motors. Even if the motor is separated from the pump with seals, wear resulting from friction and misalignment can lead to leakage of chemical fluid, causing corrosion in the bearing supporting the motor, and, eventually, failure of the motor. It is thus a standard procedure to replace bearings at regular intervals. In this article, we propose 3D-printed plastic ball bearings for use as an alternative to commercial stainless-steel ball bearings. The plastic bearings are easy to manufacture, require less time to replace, and are chemically resistant. To validate the applicability of the plastic bearings, we first conducted chemical resistance tests. Bearings were immersed in 30 caustic acid and 30 nitric acid for 30 min and 24 h, respectively. The test results showed no corrosive damage to the bearings. A test rig was set up to compare the performance of the plastic bearings with that of the commercially equivalent deep-groove ball bearings. Loading test results showed that the plastic bearings performed as well as the commercial bearing in terms of vibration level and load-handling capability. Finally, a plastic bearing was subjected to a clean-in-place process for three months. It actually outperformed the commercial bearing in terms of chemical resistance. Thus, 3D-printed plastic bearings are a viable alternative to stainless-steel ball bearings.

In urban construction projects, it is crucial to evaluate the impacts of excavation-induced ground movements in order to protect surrounding structures. These ground movements resulting in damages to the neighboring structures and facilities (i.e., parking basement) are of main concern for the geotechnical engineers. Even more, the danger exists if the nearby structure is an ancient or masonry brick building. The formations of cracks are indicators of structural damage caused by excavation-induced ground disturbances, which pose issues for excavation-related projects. Although the effects of deep excavations on existing brick masonry walls have been thoroughly researched, the impact of twin excavations on a brick masonry wall is rarely described in the literature. This work presents a 3D parametric analysis using an advanced hypoplastic model to investigate the responses of an existing isolated brick masonry wall to twin perpendicular excavations in dry sand. One after the other, twin perpendicular excavations are simulated. This article also looks at how varying sand relative densities (D_r = 30%, 50%, 70%, and 90%) affect the masonry wall. The cracks at the top of the wall were caused by the hogging deformation profile caused by the twin excavations. By raising the relative density from 30% to 90%, excavation-induced footing settlement is greatly minimized. The crack width at the top of the wall reduces as a result of the second excavation in very loose to loose sand (D_r = 30% and 50%). While the crack width on the top of the wall increases owing to the second excavation in medium to very dense sand (D_r = 70% and 90%).

Purpose : This study investigates the effectiveness of digital therapy for stroke patients in Korea. Methods : A comprehensive database search was performed using KCI, Science on, e-article, RISS, KISS and Korea OpenMed databases for randomized controlled trials (RCTs) that studied the effects of digital therapy on patients who had a stroke. This study includes RCTs published from January 2000 to July 15, 2022, which fulfilled the inclusion and exclusion criteria. A total 697 studies were screened and 30 studies were included in the final analysis. Methodological quality was assessed with the Cochrane's RoB (risk of bias) tool. Meta-analysis was performed using CMA 4.0 software. Results : A total of 56 effect sizes were calculated from the 30 selected studies. As a result of the analysis, the overall effect size of digital therapy was .59 (95 % CI=.43-.74). When classified according to type of intervention, VR (virtual reality) (g=.58, 95 % CI=.40-.75), and CACR (computer assisted cognitive rehabilitation) (g=.62, 95 % CI=.30-.95) were statistically significant. VR showed medium to large effect sizes in cognitive function (g=.78, 95 % CI=.20-1.37), psychosocial function (g=.63, 95 % CI=.20-1.07), and physical function (g=.61, 95 % CI=.38-.83). In the CACR, there was a large effect size in cognitive function (g=.84, 95 % CI=.52-1.15), but there was no significant difference in psychosocial function. Also, there was no significant difference between the two interventions in activities of daily living and no significant difference in the effect size of both interventions according to the intervention session. Furthermore, medium to large effect sizes were found for subacute and chronic stroke patients according to the duration of disease. Conclusion : This study presents evidence that digital therapy has a positive effect on various functions of stroke patients in Korea. The researchers expect to actively accept the new paradigm of digital therapy and continue to apply digital therapy in clinical practice.
