Personal information (hereinafter referred to as "PI") infringement has recently emerged as a serious social problem in Korea. PI infringement in the public and private sector is common. There were 182,666 cases of PI in 2,624 public organizations during the last three years. Online infringement cases have increased. PI leakage causes moral and economic damage and is an impediment to public confidence in public organizations seeking to manage e-government and maintain open and aboveboard administration. Thus, it is an important matter. Most cases of PI leakage result from unsatisfactory management of security, errors in home page design and insufficient system protection management. Protection management, such as encryption or management of access logs should be reinforced urgently. However, it is difficult to comprehend the scope of practical technology management satisfied legislation and regulations. Substantial protective countermeasures, such as access control, certification, log management and encryption need to be established. It is hard to deal with the massive leakage of PI and its security management. Therefore, in this study, we analyzed the conditions for the technical protection measures during the processing phase of PI. In addition, we classified the standard control items of protective measures suited to public circumstances. Therefore, this study provides a standard and checklist by which staff in public organizations can protect PI via technical management activities appropriate to laws and ordinances. In addition, this can lead to more detailed and clearer instructions on how to carry out technical protection measures and to evaluate the current status.

The objective of this study was to evaluated the photoprotective effects of porcine placenta extract (PPE) on ultraviolet B (UVB)-induced oxidative stress in human keratinocytes (HaCaT) to evaluate its functional activities as a skin food ingredient. PPE prepared by subcritical water extraction was termed SPE, and subsequently digested by enzymes to prepare E-SPE. Increased intracellular reactive oxygen species (ROS) levels (192.0%) induced by UVB were decreased by SPE and E-SPE. SPE had more effective ROS scavenging activity than E-SPE treatment. UVB treatment increased expression of tissue inhibitor of metalloproteinase 1 (TIMP-1), and this elevated expression was decreased by E-SPE treatment. High-dose treatment with E-SPE (50 and 100 µg/mL) reduced TIMP-1 expression levels of UVB-C (control) to 33.5 and 34.6%, respectively. In contrast, at low SPE doses (1 and 10 µg/mL), the treatment slightly decreased TIMP- 1 expression levels to 73.3% and 71.3% of UVB-C, respectively. In conclusion, the present study demonstrated the protective effect of SPE and E-SPE against UVB damage in keratinocytes via ROS scavenging, down-regulating MMP-2 expression and up-regulating TIMP- 1 expression. This highlights the potential for SPE as an ingredient in the preparation of functional food against photoaging.

Interior design education has been developed rapidly since the discipline established in Korea in 1980s but unfortunately the development was without any progressive transition until 1990's. When Korean Institute of Interior Design/KIID inaugurated in 1992, interior design education and related research activities began to be intensified. Despite its effort, there were still confusion about the discipline as there were many similar discipline tracks (architecture, design, fine art, & home economic, etc.) each having an own definition of interior design and introducing different aspects of educating the subject. Education program for interior design still not sufficiently supporting the needs of today's rapidly changing industry nor to prepare the diverse needs of the client. In order for interior design major to be effective in the future and fulfill the needs of current industry development within our society, re-evaluation of our current interior design educational programs in Korea is important. This study will be the beginning of a research series. As the first part of the research series, this particular study has been focused on reviewing of current status of interior design majors in the nation and its current condition. While making suggestion for the changes in curriculum, the following points will have to be considered as basic principle. First, understanding the duality of technology and design to accommodate the contents of design discipline. Second, understanding the need of practice and theory combined for practical education. And lastly, considering ways to adopt the human experience in order to develop creativity in oneself. The focus of this research is only on the interior design discipline, and research method as the following; first, analyze current status by reviewing admission data for 2010. Second, process a survey regarding the interior design education and practice-related issues in admissions and collect opinions from educators and professional designers in the field. Thirdly, with reference to previous studies, suggestions will be made for the discipline to be effective in the field. As mentioned earlier, this study series will continue and develop to suggest improvement in interior design program as well as to provide curriculums for students get ready for the industry with more up-to-date knowledges and creativities.

The EPON has been actively studied as one of the access networks for the economic configuration of FTTH. The EPON must support the dynamic bandwidth allocation to the subscribers in order to support the QoS due to its base on Ethernet technology EFM SG, which is actively working for the standardization of EPON, also recently decided to select DBA. Therefore in this paper, we designed a ONU buffer scheduling algorithm(AIWFQ) and a scheme of DBA(Class-based FCFS) for the OLT suitable for embodying MPCP of the EPON. In this paper, we proposed methods that the EPON system can make use of by measuring end to end process delay time and the buffer size in order to implement the algorithm by using the OPNET.

This study purports to find out the meanings of chemotherapy among cancer patients. The subjects of this study were selected from those patients who have taken chemotherapy at least twice at a hospital affiliated with a university. The twelve subjects agreed to join the present study and had no problem in communication with others. The data were collected through observations and interviews by the researcher. The phenomenological analysis method proposed by Giorgi was adopted for analyzing the data. The experiences of the subjects to chemotherapy were classified into 24 atributes. These attributes were also categorized into four groups such as hope, pain, fear, and ordea according to their meanings. The subjects expressed hope through the attributes such as "the wish for a new life." "the wish for healing." "the plasure form improvement of cancer." "the wish for being discharged form a hospital." "the interest in dietectic treatment." and "the trust in medical staff." Pain was represented by such attributes as "the physical pain", "the suffering from intravenous injection." "the discomfort of hospital environment." and "the economic burden." As for the attributes represention fear, "fear of being hospitalized." "tehr obscurity of uncertain situations." "the fear of side effects." "the fear of recurrence of cancer," "the lack of knowledge of the disease." Finally, nine attributes werw frouped to ordeal "the will endeavouring to recover cancer" "the adaptation to the present situation." "the giving up of being healthy," "the regret of the past life." "the recognition of significant others." "the physical changes." "the emotional changes." "the social changes." "the recollection of illness experiences." The above findings indicate that chemotherapy means hope, pain, fear, and ordeal to those cancer patinests under treatment. Hence, the nursing interventions for those cancer patients need to be directed to maintaining hope, alleviating pain and fear, and overcoming ordeal. There are some suggestions in achieving these goals : (1) the nurses caring for cancer patients need to understand the meaning of chemotherapy experienced by those patients, (2) a nursing specialty of intravenous injection needs to be developed, (3) interventions for providing emotional support should be devised, (4) nursing care should also be available to those cancer patients being dischaged at home.

Cosmetics market information is important due to advances in information communication technology and the growth of cosmetics market. This study analyzed the relationship between the pre-purchase utilization of information (commercial, neutral, personal and experiential) and the post-purchase satisfaction of skin care cosmetics, categorized as functionality, safety, economic feasibility, information reliability, purchase convenience, condition of purchase place, packaging/design of product and service. This study analyzed reliability, frequency, differences, correlation and regression analysis using SPSS ver. 24.0. The study results are summarized as follows. First, gender was a significant variable in the level of information source utilization. Women used commercial, neutral, and experiential information sources more actively than men. However, women had lower post-purchase satisfaction that could be understood through expectation disconfirmation theory. Women have very high expectations that can lower post-purchase satisfaction. Second, information source utilization can improve post-purchase satisfaction for cosmetics. The consumer post-purchase satisfact the lowest in the commercial information source; however, consumers were satisfied when the commercial informationinformation sourceenon and regre. Third, the consumeried itnformation sourceenon and regression analysis ial, neutral,source and reflected the characteristics of experiential goods. Therefore, companies should provide accurate commercial, personal and experiential information to increase consumervide accurate commercial, per as well as conduct experiential marketing.

Metaverse is a compound word of 'meta' and 'universe', which means transcendence and the world. It is a digital world where daily life and economic activities are possible. While the Metaverse is being actively used as an alternative space to enjoy leisure life since COVID-19, not much academic research on Metaverse in Korea has been done yet. Based on the previous research on Metaverse in Korea and overseas we conducted a typology analysis on cultural leisure-based Metaverse and a study on its key features. Considering the current situation in which the Metaverse era is blooming we also investigated the development trends of the Metaverse and related technologies at home and abroad. We also presented the direction of advancement of the cultural leisure-based Metaverse. This study differentiates itself from previous domestic and foreign studies by discovering and analyzing theoretical models, frameworks and features in terms of society, collaboration, and leisure use through case studies. It is meaningful that this research presents directions on further Metaverse research that reflect the current information technology (IT) and changes in life.
