This study aimed to elucidate the architectural characteristics of the cathedral architecture of the Archdiocese of Gwangju, which was completed in the period of liberation and turbulence, and the conclusions are as follows. Gwangju Archdiocese Cathedral, completed during the period of liberation and turbulence, was built with some assistance from the U.S. military or with the efforts of the faithful, and there are a number of factors such as space directing by Aps, the development of a simplified bell tower, the appearance of a stone cathedral, the application of a quenset structure, and an increase in size. show special features The indented apse appears only after liberation, and is a characteristic that appears prominently in stone churches. The simplified form in which the bell was hung by raising the outer wall appeared in the early church shows a change in the composition with a porch in front. The stone church and the quanset-structured church only appeared after liberation and were built only in the 1950s. The size of the cathedral reflects the increase in the number of believers after the Korean War, and the average area is about 1.5 times higher than before liberation. When considering the spacing of the bays as a module, the size plan followed the implicit norm of early cathedral architecture of 36.5m, but gradually decreased to 2.7m and 2.4m.

「Security Services Industry Act」made in 1976 for the purpose of contributing to the good operation of services industry by establishing the requirements for promotion, development and systematic management of services industry has been since 26 times of overall revisions. Period division of private security through overall revision of 「Security Services Industry Act」 can be roughly divided into three periods. The first is a settlement period. It is a period when the present five business areas were completed rom 1976 to 2001. Beginning with facility and escort security in 1996, five types of jobs have been prepared. so far by adding personal protection in 1996, and machine and special security in 2001. The second is a quantitative growth period. It is a period when quantitative development is made on the institutional basis. As various culture, sports and arts events are increasing based on the demand of security services due to an increase in the people's sense of security, quantitative development was made, which additionally influenced the downward trend of capital and the possibility of having two jobs through revisions. The third is a qualitative growth period. From 2013 to the present is a period when quantitative growth has slowed and qualitative growth has been made. After the period of quantitative growth, the growth slowed down. However, by raising the criteria for permission of services industry through creation of a rule for the group civil petition, by raising capital, by institutionally compensating for diverse punishment regulations, by realizing the training hours for new security guards, by permitting private education, etc, the reliability and professionality of a security guard job has been to be recovered.

As the low fertility intensifies in Korea, this study investigated fundamental differences between the government's low fertility policy and public perception of it. To this end, we selected four times 'Aging Society and Population Policy' documents and news comments for two weeks immediately after announcement of the third and fourth Policy as analysis targets. Then we conducted word frequency analysis, co-occurrence analysis and CONCOR analysis. As a result of analyses, first, direct childcare support during the first and second periods, and a social structural approach during third and fourth periods were noticeable. Second, it was revealed that both policies and comments aim for the work-family compatibility in 'parenting'. Lastly it was showed public interest in environment of raising children and the critical mind to effectiveness of the policy. This study is meaningful in that it confirmed the public perception using big data analysis, and it will help improve the direction for the future low fertility policy.

On April 28, 2021, the bereaved family of the late Samsung Group chairman Lee Kun-Hee made a gift of 9,797 items (in 21,693 pieces) from his estate to the National Museum of Korea. Among the donated cultural heritage are 535 mirrors (in 555 pieces), which constitute the largest proportion of the metal art in the donation. This article discusses a group of mirrors from the donated collection dating to the Western Han and Samhan periods - a total of twenty-three mirrors (twenty-two from the Western Han Dynasty and one from the Samhan Period) - that are presumed to have been found together. However, there is no known case of such a large number of Western Han mirrors being discovered together, raising doubts about whether this group should be considered to have been buried all together. Furthermore, the presence of a Samhan mirror among the group suggests that this one at least must have been found together with a Western Han mirror. Additionally, considering that early Samhan mirrors have been found in the southeastern part of the Korean Peninsula, particularly in the region occupied by Jinhan Confederacy (in present-day Gyeongsangbuk-do Province), it is likely that these mirrors were also excavated somewhere in Jinhan. Also, -18 is a repurposed imitation of a jade eye cover. No similar examples have been found in Korea, China, or Japan, but there are instances of bronze mirrors being used as substitutes for jade burial ornaments that have been identified in China. The repurposing and use of Western Han mirrors as circular ornaments have been observed only in Jinhan in the southern part of the Korean Peninsula, indicating that this item was likely used in Jinhan as well. Further research and discoveries are anticipated in the future.

The encapsulation of bacteria may be used to harness them for longer periods of time in order to make them viable, whereas antibiotic treatment would result in controlled release of therapeutic molecules. Encapsulated Escherichia coli GFP (green fluorescent protein) (E. coli GFP) was used here as a model for therapeutic substance - GFP fragments release (model of bioactive substances). Our aim was to evaluate the performance of bacteria encapsulated in hollow fibers (HFs) treated with antibiotic for induction of cell death. The polypropylene-surface-modified HFs were applied for E. coli encapsulation. The encapsulated bacteria were treated with tetracycline in vitro or in vivo during subcutaneous implantation into mice. The HF content was evaluated in a flow cytometer, to assess the bacteria cell membrane permeability changes induced by tetracycline treatment. It was observed that the applied membranes prevented release of bacteria through the HF wall. The E. coli GFP culture encapsulated in HF in vitro proved the tetracycline impact on bacteria viability and allows the recognition of the sequence of events within the process of bacteria death. Treatment of the SCID mice with tetracycline for 8 h proved the tetracycline impact on bacteria viability in vivo, raising the necrotic bacteria-releasing GFP fragments. It was concluded that the bacteria may be safely enclosed within the HF at the site of implantation, and when the animal is treated with antibiotic, bacteria may act as a local source of fragments of proteins expressed in the bacteria, a hypothetical bioactive factor for the host eukaryotic organism.

This study examines the relationship between sentiment of speculators and price movements in the futures markets of WTI crude oil, copper, and wheat during the period 2003~2014 using Granger causality tests. The results indicate that speculative positions overall has no predictive power for returns in each futures market. Rather, returns seem to have effects on speculators' sentiment especially during periods of both economic expansion and recovery. During a recession, meanwhile, changes of speculators' sentiment index in the WTI crude oil and copper markets provide predictive power for returns in a positive direction, suggesting that speculators' pessimistic sentiment aggravates declines in commodity prices. Since the effects of speculative positions on market prices are ambiguous, tight regulations on speculative trading are not advisable. In a bearish market, however, regulatory bodies should consider raising speculative position limits because large speculative short positions and (or) liquidation of index traders' long positions may lead steep price declines.

Childhood Cancer Foundation of ROC(CCFROC) has been founded since 1982. Its goal is to provide comprehensive care for cancer children and their families. And in turn, under the provision of good and complete care, they can be back to the school and society. To achieve this goal, it needs to get every body's effort of the society together. The foundation has been founder under this concept and tried to fulfil this task. The first step is to educate the public to know that childhood cancer can be cured and the process of treatment is long and expensive. In order to reach this life-saving procedure, campaigns for raising money is most important thing. Then, pediatric hematologists / oncologists try to organize study group, named Taiwan Pediatric Qncology Goupp(TPOG), to make treatment protocols for childhood cancers. Its primary purpose is to increase the cure rate to prove the earlier the diagnosis and treatment, the better the prognosis. The second step is to provide full support of medical expenses and further to give help for emergent need to living. Through the varieties of active exercises of cancer children or families, foundation provides opportunities for them to share the experience during the different periods of diseases. The third step is to extend the scope of training activities for many kinds of personnel who devote to the care for cancer children. On the other hand, it promotes the cooperation or communication with international organizations and sets up recreation playing ground in the communities. The aim is to provide a comprehensive and integrated care for cancer children during their education, breeding and even accomplishment period. Besides the financial support of medical care, it provides social services to give psychological support for children and their families, to strengthen doctor-patients or doctor-families relationship. The foundation provides the mourning religious activities to cherish the memory of their children who passed away and to comfort their sadness. Since the childhood cancer is curable, its treatment should be active, comprehensive and it needs to provide to all cancer children without exception. Indeed, the work of CCFROC should be changed according to the environment and different time period. But, it needs the full support from the society. We hope the scope and content of the work will be more extended and its achievement will be better than now in the future.

This study attempted to estimate the level of perceived lack of time in Korean society, to link it to time management and to identify the possible association that accounts for time shortage. I employed the gender perspective in order to reveal the dynamics and complexity of the perception of a lack of time in the population. The sample for the study was drawn from the 1999 and 2009 Korean time diary data collected by the Korean National Statistical Office. From the original data, I selected a sample of second shift families(men and women who are presently working and raising children) living in metropolitan areas(including Seoul and six major urban areas in Korea). The dependent variable was time pressure measured by a single-item question on a four-point likert scale. The results of the study showed that working mothers perceived a greater time shortage as compared to working fathers. The time use pattern showed change during the periods, indicating that people worked fewer hours in paid labor and enjoyed more leisure hours and personal care hours. However, on average, people seemed to have experienced a greater time lack in 2009 as compared to 1999. The results from the ordered logistic regression model revealed that even though there were similarities in the impact of relevant factors, men's perception of a lack of time was more closely linked with their work role and social status, while for women, this perception was influenced by work and family duties. This indicates that Korean working mothers and fathers are facing a double jeopardy of time shortage in terms of combining their work and family roles. As a result, the level of time pressure by gender is converging toward a "never enough" phase. These findings generated policy implications and detailed suggestions.

Purpose: This study compared the different sling and resistance exercises on pelvic rotation during active straight leg raises (ASLR) and on pain in patients with chronic low back pain (CLBP). Methods: Twenty subjects were divided randomly into a sling group (SG) and a resistance exercise group (REG). Internal oblique (IO), external oblique (EO), rectus abdominis (RA), and rectus femoris (RF) muscle activity; pelvic rotation angle during ASLR; and visual analogue scale, pressure pain threshold were measured. Sling and resistance exercises were then performed for 30 minutes and the measurements taken again. Results: Both groups showed significantly lower RF muscle activity and significantly higher EO and IO muscle activity (p<0.05). The RA muscle activity decreased significantly in the SG, but increased significantly in the REG (p<0.05). The pelvic rotation angle was significantly lower in the SG (p<0.05). The pain press threshold increased significantly in both groups (p<0.05). The visual analogue scale decreased significantly in the SG (p<0.05). Conclusion: Both exercises appear to be beneficial for modifying the muscle activity and pain control in the intervention of CLBP. On the other hand, the sling was more effective in increasing the pressure threshold than resistance exercise, and the pelvic rotation angle was reduced. Therefore, both exercises can help patients with CLBP change their muscle activity and control pain. CLBP patients should use a sling for short periods of time to learn to reduce the pain and control pelvic rotation.

This study was carried out to investigate effects of different night temperature treatments during nursery period on flower bud differentiation and growth of pepper cv. Cheongyang. Number of leaves, top fresh weight and top dry weight of pepper seedlings were increased with increasing the night temperature during nursery periods. And also flower bud differentiation and days to flowering were accelerated as increasing the night temperature. Plant height, stem diameter, branch length and intermode length of pepper after transplanting were height at the low night temperature ($28/11^{\circ}C$), but they were retarded at the high night temperature ($28/21^{\circ}C$) treatment. Number of lateral branches was significantly reduced at the high night temperature, but there was no a regular tendency in branching habit of the main stem by temperature treatments. Seedling growth before transplanting was retarded at the low night temperature but gradually recovered after transplanting into the plastic house. However, seedling growth at the high night temperature was shown in contrast to above response of the low night temperature.
