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.

본 연구는 한국인의 가치구조와 행동판단에서의 이중성을 대학생, 성인 및 탈북자를 중심으로 알아보고자 했다. 이를 위해 대학생 150명(남: 89명, 여: 61명)과 40세 이상 성인 155명(남: 80명, 여: 75명) 그리고 남한 사회에서의 직접적인 일상생활 경험이 없는 탈북자 80명(남: 39명, 여: 41명)에게 설문을 실시하였다. 참가자들은 한국의 전통적 특성 7개 차원 및 이에 대응하는 서구적 특성 7개 차원에서 자신의 가치관, 자신의 행동 및 타인의 행동(대학생과 성인은 남한사람의 행동 그리고 탈북자는 북한사람의 행동)을 평가하였다. 그 결과, 탈북자, 성인 그리고 대학생 순으로 전통적 가치를 더 많이 가지고 있었으며, 서구적 가치는 서로 차이가 없는 대학생과 탈북자집단보다 성인에게 더 적었다. 또한, 탈북자의 가치구조가 서로 차이가 없는 대학생과 성인집단보다 더 이중적이었다. 행동판단에서의 이중성과 관련해서, 개인주의-집단주의 차원에서 세 집단 모두 타인의 행동보다 자신의 행동을 더 높게 평가했는데, 이것은 수평적 집단주의와 수평적 개인주의에서 자신들을 더 높게 평가했기 때문이다. 또한, 나머지 평가차원에서 이 세 집단 모두 타인의 행동을 자신의 행동보다 훨씬 더 부정적으로 평가했다. 이러한 결과들을 한국사회의 문화적 변동과 관련해서 논의하였다.

The COVID-19 pandemic has posed significant community challenges towards higher education around the world. The urgent and unexpected request for full-time university courses to switch over to online teaching was a particular challenge. Online learning and learning imply a certain pedagogical knowledge content (PKC), mainly related to the design and organization for better learning and the creation of unique learning environments using digital technologies. With the help of the present academic paper, we provide some expert opinion on the PKC connected with online learning with the aim of helping non-university professionals (that is, those with lack of online learning experience) navigate these challenging times. Our findings point to the planning of learning activities with certain features, a combination of three types of presence (social, cognitive and facilitative) and the need to adapt the assessment system to new learning requirements. We will conclude by contemplating on how responding to a crisis can improve teaching and learning practices in the post-digital era.

In order to find an environment-friendly method to suppress astragal stem rot caused by the isolates of Rhizoctonia solani AG 1 and AG 4, we tested an antagonistic fungus Gliocladium virens G1 was evaluated as a biocontrol agent and estimated inorganic compounds and organic materials were tested for their effect of the disease suppression. G. virens G1 effectively inhibited mycelial growth in a dual culture and caused mycelial lysis in the culture filtrate. No adverse effect was observed when examined for seed germination and seedling growth. Promoted seedling growth was observed with the seed treatment. Seeds of astragal plant were germinated higher in the sterile soil than the natural soil. Of 14 inorganics tested, alum, aluminum sulfate and calcium oxide significantly suppressed the mycelial growth and sclerotial germination. Milled pine bark and oak sawdust also suppressed the mycelial growth. Soil amended with 1% of G. virens G1 composted with pine bark (w/v) significantly controlled astragal stem rot in the glasshouse experiments.

While screening for nematicidal activity of bacterial origins, various pseudomonads strains were inhabited in tomato rhizosphere. One isolate designated as $PE_{10}$ was selected for studies on nematicidal properties and plant growth-promoting (PGP) activity and was identified as Pseudomonas aeruginosa based on morphological features, biochemical and physiological tests, and carbohydrate utilization. To investigate nematicidal activity, Meloidogyne incognita juvenile mortality was determined using $PE_{10}$ culture filtrate. Inhibition of strain $PE_{10}$ against Fusarium oxysporum was observed using dual culture technique. Strain $PE_{10}$ showed good siderophore activity, HCN and IAA production abilities, and growth and development enhancement of tomato.

The medium compositions of Alcaligenes eutrophus were optimized for increasing PHB productivity. It is very important to optimize the concentrations of inorganic salts and trace eleme- nts as well as carbon and nitrogen sources to maximize cell growth rate and productivity. The fed-batch culture of Alcaligenes eutrophus by dual feeding of ammonia water and glucose under optimized initial medium concentrations was carried out. Glucose was fed manually according to glucose consumption rate and ammonia water by pH-stat. The final cell concentrations and PHB content in 30 hours were 122 g/l and 65% of dry cell weight(yielding 79 g of PHB/l), respectively and 2.64 g/l/hr of PHB production rate was obtained.

Studies have been made for the wireless sensor network protocols by a number of researchers to date. In particular, the studies as to the hierarchical protocol LEACH algorithm was concentrated. Various studies have been derived for the performance of the protocol is based on the LEACH protocol have been made. Improved algorithms have been proposed continuously. On the other hand, The performance comparison and evaluation of the improved algorithm is insufficient. Therefore, we compared the performance for the ML-LEACH (Multi Hop-Layered) and DL-LEACH (Dual Hop-Layered) been derived mainly LEACH. scalability, energy consumption, CH elected, network lifetime were selected as a Performance evaluation items.

For isolation of antibiotic-producing bacteria antagonistic to Fusarium oxysporum, a total of 327 microorganisms were screened from sesame-growing soils collected at various locations in Korea by the modified Herr's triple-agar-Iayer technique. Among the 36 bacterial isolates further screened by the dual culture test on tryptic soy agar, 10 were tested to show their antagonistic activity against 14 plant pathogenic fungi. Bacterial culture filtrates were shown either to inhibit some phytopathogenic fungal growth or to suppress F. oxysporum infection of sesame plants maintained in the green house. An isolate, B23, with the most prominent antagonistic activity was identified as Bacillus subtilis.

In this paper we investigate the table settings of Korean ceremonial foods for Honrye (a marriage ceremony) and Jerye (sacrificial rituals). According to the procedure of Honrye, the tables for Honrye are to be the divided into four classes; Bongchisang for Nappe ceremony, Choroyechungsang for Chorye ceremony, Keunsang for the bride and bridegroom and Pyebecksang for Kyungugorye ceremony. Jerye is to be divided into several classes; Shunjoje, Shijoje, Leeje, Kheeilje, Myoje, Sokjeulje, Sasije, and so on. Foods for Jerye are a little different from those for Honrye, but the form of table settings for Jerye is similar to that of Keunsang in Horye. Each table setting for Honrye and Jerye has its own form, that represents the meaning of that ceremony. Furthermore, foods prepared for Honrye and Jerye have the Korean dual principle of the negative and positive.
