Radical paradigm shift is being expected due to the coming of the so-called intelligent society. In the intelligent society, things or machines are able to use intelligence for the first time in history and this will bring about fundamental changes at every corner of human society. This article analyzes views of the world in order to figure out basic directions of this paradigm shift. A dualistic view of world mediated by technology is suggested for a new world view of the intelligent society, based on comparison of a traditional dualistic view of world between human-nature and a tripartite view of world between human-machine-nature. This article summarizes paradigms of the intelligent society into four ; externalization of intelligence, productivity explosion, platform society, and self-organizing society. These new paradigms will provide lots of benefits such as intelligence augmentation, production capacity increase, and self-organizing effect. But at the same time, it will increase risks of system failure because of loss of human control on technologies. In conclusion, it is argued that human choices and efforts will decide the future of the intelligent society becuase the paradigm shift is value neutral in essence.

This study is to develop a grid-based daily runoff model considering seasonal vegetation canopy condition. The model simulates the temporal and spatial variation of runoff components (surface, interflow, and baseflow), evapotranspiration (ET) and soil moisture contents of each grid element. The model is composed of three main modules of runoff, ET, and soil moisture. The total runoff was simulated by using soil water storage capacity of the day, and was allocated by introducing recession curves of each runoff component. The ET was calculated by Penman-Monteith method considering MODIS leaf area index (LAI). The daily soil moisture was routed by soil water balance equation. The model was evaluated for 930 $km^2$ Yongdam watershed. The model uses 1 km spatial data on landuse, soil, boundary, MODIS LAI. The daily weather data was built using IDW method (2000-2008). Model calibration was carried out to compare with the observed streamflow at the watershed outlet. The Nash-Sutcliffe model efficiency was 0.78~0.93. The watershed soil moisture was sensitive to precipitation and soil texture, consequently affected the streamflow, and the evapotranspiration responded to landuse type.

Impaction of the maxillary central incisor may cause social, esthetic, and functional problems in children. There are various means of treatment for the inverted maxillary central incisor, such as extraction, surgical opening followed by orthodontic traction surgical repositioning or intra-alveolar autotransplantation prior to extraction. In this case, we surgically repositioned the inverted maxillary central incisor to normal semi-erupted position in a 5-year-old boy The developmental stage of the inverted tooth was Nolla's 6.5, which indicates formation of less than one third of the root. After surgical reposition, we did follow-up for 21 months, expecting spontaneous growth Unfortunately, poor prognosis was noted further root was not observed. Such failure seems to originate from possible injury on Hertwig's epithelial root sheath by surgical trauma. We performed surgical repositioning to retain the tooth instead of extraction. However, arrest of root development occurred which is one of the critical complications. In order to increase the success rate of the surgical reposition procedure, minimal surgical trauma is required as well as selection of adequate indication and decision of proper time of treatment considering the stage of root development.

This study was conducted to understand the degree of personality and interpersonal relationships among dental hygiene students. The survey was conducted from April 1, 2021 to June 30, 2021. As a result of the study, personality was 3.42 points and interpersonal relationships were 3.46 points. In general, there was a statistically significant difference in both personality and interpersonal subdomains in interpersonal satisfaction and college life satisfaction (p<.05, p<.001). The more experience they had in clinical practice, the lower their scores for friendship and professorship among interpersonal relationships. Among the sub-domains of personality, morality and sociality were analyzed as having the highest positive correlation (r=.674), and in interpersonal relationships, the relationship between friends and professors was analyzed as high (r=.606). Therefore, for the holistic growth of dental hygiene students as preliminary dental hygienists and their adaptation to the dental care field, a long-term strategy and continuous educational approach are needed at the university for cultivating character and interpersonal relationships, which are the basics. In addition, various programs related to the duties of dental hygienists should be developed and methods to be applied should be sought.

Purpose: This preliminary study is aimed at developing standardized tools for psycho-social assessment of patients in needs for hospice/palliative care. To accomplish the purpose, investigators examined effects of perceptions of social workers on the importance of psycho-social domains of assessment in hospice/palliative care settings. Moreover, investigators paid attention to variances of perceptions of social workers' along with types of institution and credentials of those family settings. Methods: A form of questionnaire was first explored from an initial interview assessment of 10 government-certified hospice care providers and a literature review, second constructed with eight domains and 80 items, and sent by e-mail to 55 institutions and hospitals providing hospice/palliative cares in Korea. Lastly, a total of 31 agencies returned with a completed responses and consent form (56% response rate). SPSS program (version 18.0) was used for data analysis. Results: Study found that social workers perceived patients' family background (m=4.53, 5-point scale) as the most important assessment domain, whereas economic conditions (4.06 point) the least important. Social workers' perception varied by credentials (i.e., license types, training, full-time position, types of care facility). Conclusion: Based upon study findings, investigators can conclude strong needs for developing a assessment tool that measures multiple domains (i.e., psychological, social and ecological aspects) of patients. A standardized assessment tool should be structured with 2 axis (center/core and expanded/peripheral) and tailored for institution type. Second, professional trainings must be provided by strengthening legal institutionalization and fostering qualified social workers with full responsibilities of hospice and palliative care patients.

The study conducted research investigating their about knowledge and attitude of toward elderly aimed at 251 students in the Department of Dental Hygiene located in some areas of Gyeongbuk and Gyeongnam. The total average score concerning knowledge about the elderly was found to be 11.78 out of a full score of 25 points, and the level of physical and physiological knowledge was the highest. As regards the total average of the attitude toward the elderly, it posted at 98.58 points out of a full score of 150 points and the attitude regarding the aspect of welfare was the most positive. About toward elderly correlation of knowledge and attitude between higher knowledge score more positive was attitude about toward elderly. From the above results, it would be necessary to reinforce not only the physical and physiological aspect of the elderly but also the education in the family and social areas during the development of educational contents for the Department of Dental Hygiene in relation to the elderly. Furthermore, it is deemed imperative to improve the relationship between the younger generations and the elder generation by having students practice in institutions related to the elderly, such as institutions for senior nursing and senior welfare centers and to develop a generational community program that will provoke positive interactions between them.

최근 한국보건사회연구원이 국민의 의약품 사용실태를 조사한 결과에 의하면 1천명중 33명이 매일 항생제를 복용한다. 이는 OECD 회원국가의 평균치 21명보다 월등히 높은 비율로, 약물남용이 우려할 만한 수준임을 보여준다. 이 조사는 또 97년도 의료보험 환자중 병$\cdot$의원에서 58.9$\%$가 항생제를 처방받았다고 밝혔다. 폐렴구균의 70$\~$80$\%$가 항생제 남용으로 페니실린에 내성을 보였는데 이는 아시아 최고수준이다. 약물남용은 항생제 뿐 아니다. 많은 사람들이 의사처방 없이 자가처방으로 약을 구입하며, 자가처방의 절반은 감기약을 구입하는데 이 경우 부적절한 처방이 문제된다. 더구나 감기약은 1가지만으로도 남용할 경우 부작용이 많은데 `판피린과 콘택 600을 주세요` 라는 식으로 물약과 알약을 동시에 주문한다. 이와 같은 약의 중복사용은 약물의 남용효과를 더욱 크게 한다.

2005년 9월의 총선거를 거쳐 11월에 독일에서 처음으로 여성 수상인 앙켈라 메르켈 총리가 이끄는 대연립정권이 탄생하였다. 총선거 전에는 메르켈 총리가 소속된 기독민주사회동맹(CDU/CSU)이 자유민주당(FDP)과 연린정권을 구성하는 것으로 예상되었으나 사회민주당(SDP)의 선거전 후반의 맹렬한 추격으로 CDU/CSU의 득표수가 늘어나지 못하여, 결국 CDU/CSU는 SPD와 같이 대연립정권을 꾸미게 되었다. 이 양 당은 선거 전에 에너지정책 분야에서는 서로 용납치 않는 정책강력을 발표하여 왔었다. 특히 원자력 정책에 있어서는 양 당의 의견에 격차가 심하여 총선거 후에 실시되었던 정책 협의과정에서 최후까지 합의가 이루어지지 못한 사항의 하나였다. 2005년 11월 11일에 발표된 대연립정권의 정책강령에 담겨진 에너지 정책의 개요를 소개함과 동시에 에너지 정책에 있어서의 앞으로의 과제에 관하여 기술한다.
