The purpose of this study was to investigate the preferred methods for making summer kimchi as a basic research of making commercial kimchi. Questionnaire were collected from 590 housewives nationwide in Korea, and the data were analyzed by SPSS program. The results were as follows: (1) The average salting time of Chinese cabbage was 3~5 hrs when the combined method of dry and brine salting was used, regardless of the region. (2) Seven jeotkals (salt-fermented fishes) including anchovy, anchovy juice, shrimp, northern sand lance juice, hair-tail viscera, flatfish and yellow corvenia were mainly used in kimchi. Among them, anchovy and anchovy juice jeotkals were preferred to all others in Southern area (Busan, Gwangju, Gyeongnam, Gyeongbuk, Jeonnam), while shrimp jeotkal in Seoul, Gwangju, Jeonbuk, Chungnam and Jeju, and northern sand lance juice jeotkal in Daegu, Daejeon and Gyeonggi, respectively. In most regions, however, blending type of 2 jeotkals was used in kimchi. (3) Eleven ingredients such as red pepper, garlic, ginger, green onion, radish, leek, onion, carrot, sugar, sesame and MSG were used as basic components for making kimchi. In particular, MSG was used as a basic ingredient regardless of region and age. However, a standard taste for making kimchi was depended on housewife in this study.

Spatio-temporal variation in fruit set in orchids would affect long-term population viability and will influence genetic diversity over many generations. The aim of this study was to examine the breeding system of the nectariferous terrestrial orchid Epipactis thunbergii, to specifically determine levels of fruit set in terms of time and space under natural conditions. We examined pollination under natural conditions and conducted hand pollination experiments during a 2-year survey in four populations located along 1.5 km of coastal line in Jinguiri (rual village) [Jeollanam-do (province), southern Korea]. We found that, over a 2-year period, levels of percentage of fruit set were similar within patches of the four populations. By contrast, we detected significant differences in the percentage of fruit set among patches. We also found that plants with larger inflorescence size produced significantly more fruits than plants with fewer flowers. Over a 2-year period, the percentage of fruit set for E. thunbergii was similar but low (14.1%) compared to that averaged for eighty-four rewarding species (37.1%). However, an increase in fruit set was achieved by hand-pollinations: artificial self-pollination (90.5-95.2%), artificial geitonogamy (94.7-95.0%), and cross-pollination (artificial xenogamy, 91.3-91.4%). No emasculated flowers produced fruits and no automatic pollination was found in E. thunbergii. Our findings suggest that E. thunbergii is a self-compatible terrestrial orchid that depends on pollinators (insects) to achieve fruit set in natural habitats, and that local environmental conditions were similar over a period of 2 years in the study area. Our results also highlight the cryptic variation of fruit production in time, but more pronounced variability in space.

Smart work is deeply embedded in our contemporary lives. This is called Smart Life. The expansion of communication, caused by smart life is utilized for the political purposes of politicians, political candidates, and political policies. Chiefly, smart life includes improvement in awareness, personal relations, and policy advocacy. Socially, smart life leads the proliferation of issues and civil movement. In particular, smart life has a significant effect on culture. In the case of K-POP, it is disseminated going beyond space time. It enhances economic value added by joining and sharing at the same time. Smart life has numerous advantages such as improving the quality of life, but it might cause inconvenience depending on users because there are differences in acceptance according to generations. Due to the heavy weight on the device, there are some side-effects such as lacking in human thinking, disclosure in private life, lacking in basic securities, increase in information addicts who are anxious when they do not get on the Internet or SNS, and interference with work. However, this inconvenience can change into convenience when users are accustomed to it. Like this, smart life influences politics, economy, society, and culture a lot. Working environment of smart life is a new paradigm, which can generate high performance through working in an exciting and bright atmosphere with easy economy and putting value on results.

This study examined radiation damage and the optimal gamma-ray dose for mutation breeding in oat (Avena sativa L. cv. Samhan). The seed germination rate decreased as the dose increased over 500 Gy. The median lethal dose (LD₅₀) was approximately 392 Gy. The median reduction dose (RD₅₀) for plant height, tiller number, root length, and flash weight was 411, 403, 394, and 411 Gy, respectively. The optimal dose of gamma irradiation for inducing oat mutation appears to be in the range 300-400 Gy. We performed the comet assay to observe nuclear DNA damage induced by gamma-ray irradiation. This assay showed a clear difference with gamma-ray treatments. DNA damage increased temporarily 7 days after treatment depending on the dose, while no significant difference was identified in response to 300 Gy 30 days after the gamma-ray treatments. The growth characteristics of the M₂ generation decreased as the dose increased over 400 Gy.

Recently policy coordination and integration have emerged as core challenges as complexity and uncertainty of policy. Especially as innovation and environment policy is expanding and its position is being further elevated within policy hierarchy, policy integration has emerged as core governance challenges for nation states. OECD countries emphasized the need of coordination and integration of policy by introducing concepts such as 'Environmental Policy Integration', 'the Third generation innovation policy', 'integrated innovation policy'. This study analysed the background, concepts, objects, mechanisms, and major issues of integrated innovation policy and various attempts for integrate innovation policy by policy level and cycle. Developing integrated innovation policies has become increasingly important for the EU and OECD countries in recent years. OECD countries including Finland have developed broader policy agendas for balancing policy objectives and aims of other policy sectors and horizontal relationships with other policy sectors. Policy integration helps to reorient policies where related policies are in conflict and to ensure coherence across different policy areas. Policy integration emphasizes long-term policy adjustment and adaptation based on social agreement and common vision.

The purpose of this study was to examine whether parental beliefs, value of children, and filial obligation were related. The subjects were 748 students(male 323, female 425) who were currently enrolled at university located in Seoul. The instruments used for this study were Filial Obligation Scale(Cho, 2002), Parenting Beliefs Questionnaire, and Value of Children by Arnold et al.(1975, 2001). Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlations by SPSS PC Program. The results showed that university students generally demonstrated a higher level of individual-oriented beliefs than relation-oriented beliefs on parental beliefs. With regard to parental beliefs, family relation-oriented beliefs was relatively low in comparison with independence/autonomy-oriented beliefs, happiness-oriented beliefs, and cognition/knowledge-oriented beliefs. In addition, emotional value of children was relatively high in comparison with instrumental value of children. Also, male university students possessed a higher level of filial obligation. the level of cohabitation experience with their parents played a significant role in affecting the level of filial obligation. Unsurprisingly, a higher relation-oriented parental beliefs and emotional value of children demonstrated a higher level of filial obligation. There were also positive relationships between emotional value, instrumental value, and filial obligation. Hence, this study suggests that a practical, functional training services and resources for future parents must be ensued.

Dentinogenesis imperfecta is an example of an inheritable dentinal defect originating during the histodifferentiation stage of tooth development, with involvement of the primary and permanent teeth. Shields, Bixler and El-Kafrawy proposed three types of Dentinogenesis imperfecta : Type I, II, III. Witkop reported a prevalence of 1 in 8000 with the trait, and no significant difference between male and female. Affected teeth have red-brown discoloration often with distinctive wearness of occlusal surface of posterior teeth and incisal surface of anterior teeth. Once enamel seperated from underlying defective dentin, the dentin demonstrates significantly acclerated attrision. Radiographically, the teeth have thin roots, bulbous crown, cervical constriction, and obliteration of the root canals and pulp chambers. In primary dentition periapical lesions or multiple root fractures are often observed. In successive generations the phenotypes of discoloration and wearness of teeth occurred, and one of the patient's subships, 10 year-old sister, showed general discoloration of her teeth and mild wearness. In this case, a 4 year-old male reported to the Yonsei University Pedodontics clinic, with a chief complaint of discolored teeth. The teeth showed generally yellowish-brown discoloration and moderate wearness. In radiographic features, obliteration of pulp, bulbous crown, and short roots were observed. It was diagnosed as Dentinogenesis imperfecta. The posterior teeth were restored with Stainless Steel Crown, and defective incisors including left upper primary central incisor which was extracted due to a root fracture with Open-faced Stainless Steel crown.

The self-segmentation of Seoin(西人) School and the appearance of Soron(少論) School in the 17th century Joseon society has an important meaning in the political history. Soron School(少論學派) had quite different line in their thought and public position from the Noron(老論) School represented by Song Shi-yeol. With such thought and position, Soron School added a vitality to the barren climate of Joseon intellectual society and soon became an important school of it. Especially, the senior leaders of early Soron School shared the culture of discussion and dialogue which was represented by the phrase, "the forest of debate and the hill of argument". Accordingly, Soron School could form an unique academic tradition which was different from other schools. For instance, Park Se-dang(朴世堂), Nam Gu-man(南九萬), Yoon Jeung(尹拯) and Park Se-chae(朴世采) had relatively flexible Conception of Heresy; which was in the same context with the academic position of Soron School that allowed diverse approaches to truth each as the path of justice. Furthermore, the leaders of Soron School continued dialogue and discussion on the wide range of current issues. They deeply sympathized with the Tangpyeong-ron(蕩平論), which was to appoint important government positions equally from multiple schools. They thought that the Tangpyeong-ron(蕩平論) was to avoid the harmful influence of conflicts between schools, the Bungdang(朋黨), and tried to tune and compromise the different opinions of different schools. In fact, the "Hwanggeuk Tangpyeong-ron" (皇極蕩平論) submitted by Park Se-chae was the summarization of the discussions shared by the Soron School leaders. Consequently, the seniors of Soron School practiced their philosophy that "the true academic practice is the communication" by keeping the dialogue with other schools while respecting the difference of each other, rather than staying comfortably in the closed academic fence of uniformity. Such communicative academic practice adopting discussion and dialogue had been succeeded to the second generation of Soron School and it remained as an unique academic tradition of Soron School.
