'Private Garden', is a legal concept that encourages the opening of private gardens to the public. Twenty-five private gardens have registered with the Forest Service since the 2015 policy was enacted. Although it is a positive system in terms of spreading and encouraging garden culture, the exact nature, role, and designation requirements have not been fully discussed. The purpose of this study is to analyze the characteristics of 25 private gardens in Korea. The results of the study noted that the southern region occupied a large part of the geographical distribution of the private gardens, which is due to the natural and climatic conditions, the policies of the local governments, and the discretion of public officials. In addition, the gardens are almost all made up of modern gardens; there was only one house garden from the Joseon Dynasty. The owners of the gardens range from their 50s to 80s in age. The gardens were started because the owner believed it was a good endeavor, but many owners felt that it was difficult to manage the enlarged garden and eventually opened it through as a Private Garden in anticipation of receiving economic support. There are also owners who are willing to revitalize the area. In addition, profits are generated from facilities other than the gardens, and some operate related programs to promote the culture of gardening. For a sustainable Private Garden system, it is necessary to check the registration criteria and establish a clear role in the region. There is also a need for further measures for management and marketing. This study is meaningful as basic research on the Private Garden system that is not yet systematic.

The purpose of this paper is to survey the influence of the culture change on the dress and personal adornments, and to survey the change of factors from the August 15. 1945 to 1960, in connection with the social and cultural background, applying B. Malinowski′s "Theory of Culture Change" which means an acculturation is the change′s elements of the dress and its ornaments. It is remarkable that the dress and personal adornments of Korean women after August 15, 1945 has great change from the traditional dress of the thousands years. Through the Liveration on August 15, 1945, American military government and the establishment of the Korean government, American democracy has brought many changes on Korean society. Advancement of education, an society with developed economic life, and introduction of scientific skill have influenced on the women′s way of thinking and a style of behavior and the view of value. The acculturation, the supply of mass communication, introduction of new institution and the reorganization of the old institution, the change of the economic situation, the change of the educational system, the change of the point of value, the development of scientific skill have greatly influenced on the dress and personal adornments. Modern dress and personal adornments of Korean women has the following developing procedure. The Liberation from Japan on the 15th, of August, 1945, the stationing of American Soldiers during hte Koran War, returning of the oversea′s brethern, and the mass communication have the direct and indirect contact with western civilization, and bring the occasion of development of the modern dress of Korean women. The increase of mass communication, such as radio, TV, newspaper, magazines and the frequent fashion shows showed fine design and practical western style dress to the women. This was the real beginning of the western style dress in Korea. By the increase of employment and the improvement of the economic situation, the consumption of clothing and the adornments was increased, so that a wide variety of fashions was set, and numerous kind and form of dress came in. As the increase of the number of women students, their practical and free dress life demanded western style dress. After the Liberation from Japan, the open-door policy of sex, public morals and traditional ethics became lax, and in this disordered society, indecent expose of the body was common. By the different kind of technological development, the form, fabrics, colors and patterns in clothes were much influenced and the hair style, make up, shoes and adornments were much influenced too. As shown above, the change of the dress has the same connection with that of society and culture. This shows that the dress and personal adornments represent clearly the cultural phenomenon of the society and cultural change of the society.

The aim of this study was to assist the development of parenting-aid policies by analyzing information from life perspectives, family system theory, and integrated family policy perspectives. For this purpose, we conducted a literature using a variety of sources including internet sites, laws, published material related to current parenting-aid policies. Based on analyses we formulated four agendas: empowering parent competency, supporting diverse family parenting, guaranteeing parent's rights, and supporting parenting of dual-income families parenting. The results were as follow: Firstly, for empowering parent competency, we proposed the development of family relationship empowerment programs including family life cycle and children-raising support services. Secondly, for diverse family parenting, we proposed access to integrated parenting-aid programs dependent on family types. Thirdly, for guaranteeing parent’s rights, we proposed the supporting of child raising costs and tax returns to families with children, and provide child allowances. Finally, for dual-income family parenting, we proposed that schools and communities must recognize that dual-income families are a universal family type, establish family friendly business culture, and to develop a more democratic domestic family-relationship. This policy proposed a new paradigm where parents must be recognized as partners and stakeholder in development of family related policies. Ultimately, such policies will contribute to increased birth rate and development of a more respectful society.

Under the light intensity of 25-72$\mu$E/ m$^{2}$/s Botryococcus braunii UTEX 572 grew faster than Botryococcus sp. GE 24 isolated from a freshwater lake. The specific growth rate ($\mu$) of B. braunii UTEX 572 was highest at 0.260 (1/day) on a dry weight basis in Chu 13 medium from 1 to 9 days of incubation and then continuously decreased. Carbohydrate concentration and cellular nitrogen and phosphorus contents of B. braunii UTEX 572 gradually decreased with light intensity over a range of 25-72$\mu$E/m$^{2}$2/s, whereas the concentrations of protein and cellular N:P ratio increased with light intensity. Chlorophyll-a concentration showed a decreasing tendency with light intensity. The dry weight of B. braunii UTEX 572 increased in the highest rate of 83 mg/l/day at pH 8.0. When the N: P ratio of Chu 13 medium was adjusted to 50: 1 by addition of nitrogen source, dry weight increasing rate was 115 mg/l/day between 20 and 28 days of incubation which was the highest value during the cultivation. Cell growth in an open culture of B. braunii UTEX 572 was highest with Chu 13 medium, whereas that with Chu 13 medium adjusted to pH 7.0, containing 250 mg/l penicillin, or containing 1% glucose was reduced on a large scale. However, this result shows the possibility of the mass cultivation of B. braunii UTEX 572 in an open system competing with other microorganisms.

The advantages of the OPS techniques(Vajta G et al, Mol Reprod Dev 51: 53-58,1998) give 1) high survival rates of various types of eggs, 2) quick and simple process, 3) inexpensive equipment and reduced chilling injury. The efficiency of IVM/IVF technique in the porcine species is relatively lower than that obtained in other species such as ruminants. Two experiments were designed to investigate the effects of in-vitro fertilization of porcine oocytes matures using different OPS protocol for chilling and warming of vitrification. Porcine oocytes from ovaries collected at abattoir were matured for 44 hours in TCM199 Earle's salt supplemental with pyruvate, pff, L-cysteine, hormones and gentamycin. Oocytes were denuded and fertilized with frozen boar semen by common method. Porcine embryos produced routinely by in-vitro culture system of NCSU23 medium. The vitrification and the warming were conducted by OPS method with the glass micropipette instead of straw vessels and modified the protocol of G.Vajta(1999). In Exp 1, Chilling/Warming:Holding Medium(HM)+EG+DMSO/HM +sucrose Medium(SM) at 39$^{\circ}C$ warm stage. In Exp 2, : PBS+CS+EG+Ficoll+ Trehalose/PBS+Trehalose at 25$^{\circ}C$ stage. Filling, freezing, packing, thawing out and further culturing were performed to follow the basic protocol of G Vajta. During IVM-lVC and post-warming, fertilization parameter and developmental potential were compared to and statistically analysed. It was not significantly different from Exp 1 and Exp 2 but 25$^{\circ}C$ of stage was slightly higher on the morula/blastocyst forming rate and better atmosphere for worker than that at 39$^{\circ}C$ stage.

For the diagnosis of cancer-related diseases in clinical practice, pathological examination using biopsy is essential after basic diagnosis using imaging equipment. In order to proceed with such a biopsy, the assistance of an oncologist, clinical pathologist, etc. with specialized knowledge and the minimum required time are essential for confirmation. In recent years, research related to the establishment of a system capable of automatic classification of cancer cells using artificial intelligence is being actively conducted. However, previous studies show limitations in the type and accuracy of cells based on a limited algorithm. In this study, we propose a method to identify a total of 4 cancer cells through a convolutional neural network, a kind of deep learning. The optical images obtained through cell culture were learned through EfficientNet after performing pre-processing such as identification of the location of cells and image segmentation using OpenCV. The model used various hyper parameters based on EfficientNet, and trained InceptionV3 to compare and analyze the performance. As a result, cells were classified with a high accuracy of 96.8%, and this analysis method is expected to be helpful in confirming cancer.

Poly(ε-ʟ-lysine) (ε-PL) is a novel bioactive polymer secreted by filamentous bacteria. Owing to lack of a genetic system for most ε-PL-producing strains, very little research on enhancing ε-PL biosynthesis by genetic manipulation has been reported. In this study, an effective genetic system was established via intergeneric conjugal transfer for Streptomyces albulus PD-1, a famous ε-PL-producing strain. Using the established genetic system, the Vitreoscilla hemoglobin (VHb) gene was integrated into the chromosome of S. albulus PD-1 to alleviate oxygen limitation and to enhance the biosynthesis of ε-PL in submerged fermentation. Ultimately, the production of ε-PL increased from 22.7 g/l to 34.2 g/l after fed-batch culture in a 5 L bioreactor. Determination of the oxygen uptake rate, transcriptional level of ε-PL synthetase gene, and ATP level unveiled that the expression of VHb in S. albulus PD-1 enhanced ε-PL biosynthesis by improving respiration and ATP supply. To the best of our knowledge, this is the first report on enhancing ε-PL production by chromosomal integration of the VHb gene in an ε-PL-producing strain, and it will open a new avenue for ε-PL production.

This study examines the establishment of Sea-po (서포) in the opening period of Korea at the end of the 19th century. The role they played, the particular situations and their geographical characteristics are researched, The earliest sea-po was Koh-je-hong sea-po, which was established in Tae­kwang-kyo at the end of 1880s. Around 1905, a specialised book distribution system was set up with establishement of Chu-han-yung book store, Kim-sang-man book store, Jesuit book store, Tae-dong su-si, Kae-myung sea-kwan, Tong-wha seo-kwan. The owners of the seo-pos were pioneers in introducing modern culture with nationalistic consciousness, although they were primarily businessmen and their social origins varied. The primary role of seo-pos was selling a variety of books but some combined printing and publication of books as well. It seems that publication business took roots around 1908, though it is difficult to know the accurate dates of first attempts. Some sea-pas offered book rental services for poor people who could not easily afford to purchase books. A certain amount of deposit had to be paid to benefit from the services. Jesuit Bookstore in Pyungyang had a library facility with a large stock or books in the same building open to public for free. These sea-pas started mainly in Seoul and Pyungyang, which were traditional centers for economic and cultural affairs. Early introduction of foreign cultures and commercial developments in these areas contributed to the establishment of sea-pos. The sea-po which took charge of book distribution in the provinces was set up around 1906. One of the important findings of this study is that the geographical distribution of sea-po shows the following three characteristics. First is that the area such as Seoul, Taegu and Chunju were the traditional centers of publishing culture from which Pang­gak-bon(방각본) emerged. Second characteristic is Pyungyang and the surrounding Pyungbuk province, and harbors like Inchon and Pusan, which had the benefits of early spread of modem cultures. Third characteristic is Kaesung and the surrounding Hwanghae province which bridged Pyungyang and Seoul. The reception of foreign cultures stimulated the commercial spirits traditionally attributed to Kaesung to establish sea-pas most actively.

The tourism industry has a great influence on national economy activation. The development of IT technology has enabled the collection and analysis of personal profile information, location information and activity information based on the characteristics, behavior, purchase propensity and interest of tourists. In order to realize this, the implementation of convergence smart tourism information service platform is completed by developing business model, IoT & Big Data integration management system, big data algorithm development and analysis platform in three stages. The underlying technology of the platform and algorithm needs a process of adopting open source, expanding the service element on the basis of it, and then complementing the problem through the test-bed demonstration test that connects the area. Using this platform, it is possible to develop a smart tourism environment that can provide customized services for each tourist by analyzing various information in an integrated manner. Also, it will be possible to improve the life of tourist destination residents and contribute to regional revitalization and job creation through the creation of smart tourism ecosystem focused on the region.
