This study examines the status quo of Korean archives and records management from the Governmental as well as professional activities for the development of the field in relation to the new legislation on records management. Among many concerns, this study primarily explores the following four perspectives: 1) the Government Archives and Records Services; 2) the Korean Association of Archives; 3) the Korean Society of Archives and Records Management; 4) the Journal of Korean Society of Archives and Records Management. One of the primary tasks of the is to build the special depository within which the Presidential Library should be located. As a result, the position of the GARS can be elevated and directed by an official at the level of vice-minister right under a president as a governmental representative of managing the public records. In this manner, GARS can sustain its independency and take custody of public records across government agencies. made efforts in regard to the preservation of paper records, the preservation of digital resources in new media formats, facilities and equipments, education of archivists and continuing, training of practitioners, and policy-making of records preservation. For further development, academia and corporate should cooperate continuously to face with the current problems. has held three international conferences to date. The topics of conferences include respectively: 1) records management and archival education of Korea, Japan, and China; 2) knowledge management and metadata for the fulfillment of archives and information science; and 3) electronic records management and preservation with the understanding of ongoing archival research in the States, Europe, and Asia. The Society continues to play a leading role in both of theory and practice for the development of archival science in Korea. It should also suggest an educational model of archival curricula that fits into the Korean context. The Journals of Records Management & Archives Society of Korea have been published on the six major topics to date. Findings suggest that "Special Archives" on regional or topical collections are desirable because it can house subject holdings on specialty or particular figures in that region. In addition, archival education at the undergraduate level is more desirable for Korean situations where practitioners are strongly needed and professionals with master degrees go to manager positions. Departments of Library and Information Science in universities, therefore, are needed to open archival science major or track at the undergraduate level in order to meet current market demands. The qualification of professional archivists should be moderate as well.

This study was performed to support the 6th forest basic planning by Korea Forest Service as predicting the change of forestland area by the transition of land use type in the future over 35 years in South Korea. It is very important to analyze upcoming forestland area change for future forest planning because forestland plays a basic role to predict forest resources change for afforestation, production and management in the future. Therefore, the transitional interaction between land use types in future of South Korea was predicted in this study using econometrical models based on past trend data of land use type and related variables. The econometrical model based on maximum discounted profits theory for land use type determination was used to estimate total quantitative change by forestland, agricultural land and urban area at national scale using explanatory variables such as forestry value added, agricultural income and population during over 46 years. In result, it was analyzed that forestland area would decrease continuously at approximately 29,000 ha by 2027 while urban area increases in South Korea. However, it was predicted that the forestland area would be started to increase gradually at 170,000 ha by 2050 because urban area was reduced according to population decrement from 2032 in South Korea. We could find out that the increment of forestland would be attributed to social problems such as urban hollowing and localities extinction phenomenon by steep decrement of population from 2032. The decrement and increment of forestland by unbalanced population immigration to major cities and migration to localities might cause many social and economic problems against national sustainable development, so that future strategies and policies for forestland should be established considering such future change trends of land use type for balanced development and reasonable forestland use and conservation.

This study explored all domestic and international theories for maintenance and health enhancement of an old and big tree, and carried out the anatomical survey of the operation part of the tree toward he current status of domestic surgery and the perception survey of an expert group, and drew out following conclusion through the process of suggesting its reform plan. First, as a result of analyzing the correlation of the 67 subject trees with their ages, growth status. surroundings, it revealed that they were closely related to positional characteristic, damage size, whereas were little related to materials by fillers. Second, the size of the affected part was the most frequent at the bough sheared part under $0.09m^2$, and the hollow size by position(part) was the biggest at 'root + stem' starting from the behind of the main root and stem As a result of analyzing the correlation, the same result was elicited at the group with low correlation. Third, the problem was serious in charging the fillers (especially urethane) in the big hollow or exposed root produced at the behind of the root and stem part, or surface-processing it. The benefit by charging the hollow part was analyzed as not so much. Fourth, the surface-processing of fillers currently used (artificial bark) is mainly 'epoxy+woven fabric+cork', but it is not flexible, so it has brought forth problems of frequent cracks and cracked surface at the joint part with the treetextured part. Fifth, the correlation with the external status of the operated part was very high with the closeness, surface condition, formation of adhesive tissue and internal survey result. Sixth, the most influential thing on flushing by the wrong management of an old and big tree was banking, and a wrong pruning was the source of the ground part damage. In pruning a small bough can easily recover itself from its damage as its formation of adhesive tissue when it is cut by a standard method. Seventh, the parameters affecting the times of related business handling of an old and big tree are 'the need of the conscious reform of the manager and related business'. Eighth, a reform plan in an institutional aspect can include the arrangement of the law and organization of the old and big tree management and preservation at an institutional aspect. This study for preparing a reform plan through the status survey of the designated old and big tree, has a limit inducing a reform plan based on the status survey through individual research, and a weak point suggesting grounds by any statistical data. This can be complemented by subsequent studies.

This experiment was designed to explore the specific functional interrelations between the vestibular semicircular canals and the extraocular muscles which may disclose the neural organization, connecting the vestibular canals and each ocular motor nuclei in the brain system, for vestibuloocular reflex mechanism. In urethane anesthetized rabbits, a fine wire insulated except the cut cross section of its tip was inserted into the canals closely to the ampullary receptor organs through the minute holes provided on the osseous canal wall for monopolar stimulation of each canal nerve. All extraocular muscles of both eyes were ligated and cut at their insertio, and the isometric tension and EMG responses of the extraocular muscles to the vestibular canal nerve stimulation were recorded by means of a physiographic recorder. Upon stimulation of the semicircular canal nerve, direction if the eye movement was also observed. The experimental results were as follows. 1) Single canal nerve stimulation with high frequency square waves (240 cps, 0. 1 msec) caused excitation of three extraocular muscles and inhibition of remaining three muscles in the bilateral eyes; stimulation of any canal nerve of a unilateral labyrinth caused excitation (contraction) of the superior rectus, superior oblique and medial rectus muscles and inhibition (relaxation) of the inferior rectus, inferior oblique and lateral rectos muscles in the ipsilateral eye, and it caused the opposite events in the contralateral eye. 2) By the overlapped stimulation of triple canal nerves of a unilateral labyrinth, unidirectional (excitatory or inhibitory) summation of the individual canal effects on a given extraocular muscles was demonstrated, and this indicates that three different canals of a unilateral vestibular system exert similar effect on a given extraocular muscles. 3) Based on the above experimental evidences, a simple rule by which one can define the vestibular excitatory and inhibitory input sources to all the extraocular muscles is proposed; the superior rectus, superior oblique and medial rectus muscles receive excitatory impulses from the ipsilateral vestibular canals, and the inferior rectus, inferior oblique and lateral rectus muscles from the contralateral canals; the opposite relationship applies for vestibular inhibitory impulses to the extraocular muscles. 4) According to the specific direction of the eye movements induced by the individual canal nerve stimulation, an extraocutar muscle exerting major role (a muscle of primary contraction) and two muscles of synergistic contraction could be differentiated in both eyes. 5) When these experimental results were compared to the well known observations of Cohen et al. (1964) made in the cats, extraocular muscles of primary contraction were the same but those of synergistic contraction were partially different. Moreover, the oblique muscle responses to each canal nerve excitation appeared to be all identical. However, the responnes of horizontal (medial and lateral) and vertical (superior and inferior) rectus muscles showed considerable differences. By critical analysis of these data, the author was able to locate theoretical contradictions in the observations of Cohen et al. but not in the author's results. 6) An attempt was also made to compare the functional observation of this experiment to the morphological findings of Carpenter and his associates obtained by degeneration experiments in the monkeys, and it was able to find some significant coincidence between there two works of different approach. In summary, the author has demonstrated that the well known observations of Cohen et al. on the vestibulo-ocular interrelation contain important experimental errors which can he proved by theoretical evaluation and substantiated by a series of experiments. Based on such experimental evidences, a new rule is proposed to define the interrelation between the vestibular canals and the extraocular muscles.

대순진리회는 '구천응원뇌성보화천존강성상제(이하 '구천상제')'를 주신(主神)으로 신앙하는 종교단체이다. 그렇다면 대순진리회의 '구천상제'와 중국 도교에서 모셔지는 '구천응원뇌성보화천존'(이하 '보화천존')은 어떤 연관성이 있는 것인가? 이런 질문을 토대로 본 글에서는 이 신들의 기원과 칭호, 도세법문(度世法門 : 세상을 제도하고자 펼친 법도) 등의 관점에서 그 차이점과 공통점을 하나씩 비교해 보았다. 먼저 기원이라는 측면에서 '구천상제'와 '보화천존'을 비교해보면, '구천상제'는 천지인 삼계의 최고신으로서 강씨 가문을 선택하여 인간의 육신으로 태어났다. 강씨 성은 상고 신농씨에서 시작되었는데, 고대 문헌에 근거하면 신농씨는 태양신, 남쪽, 불(火) 등으로 상징화된다. 이런 상징들은 '구천상제'가 인간으로 태어날 때 나타난 "하늘이 남북으로 갈라지다", "큰 불덩이가 몸을 덮치다", "천지가 밝아지는도다" 등의 현상들에서 찾아볼 수 있다. 도교의 '보화천존'은 뇌신의 특징을 가지면서 일신(日神), 월신(月神)과 관계를 맺고 있는데, 이런 면들은 신농씨로부터 분석한 '구천상제'의 신적 기원과 일치하고 있다. 또한 도교에서는 신농씨가 다스리던 세상을 중국 상고시대의 가장 이상적인 사회형태로 보고 있는데, 이것을 '구천상제'가 건설하려는 후천선경과 연관 지어 생각해보면 '구천상제'가 신농씨의 후손인 강씨 종가에서 태어난 배경을 이해할 수 있다. 도교의 '보화천존' 역시 중생의 이익을 도모하고, 조화로운 인간세상을 만드는 것을 목표로 삼고 있으며, 이것은 대순진리회 '구천상제'가 행한 대순의 목적과 거의 비슷하다고 볼 수 있다. 다음으로 '구천상제'와 '보화천존'은 칭호에서도 공통점과 차이점을 살펴볼 수 있다. 단적으로 말하자면, '구천상제'에는 '보화천존'에 비해 '강성상제'라는 칭호가 추가되어 있다는 것이다. 또한 도교에서는 '보화천존'을 최고신으로 모시지 않으며, '구천상제' 신앙에서는 '보화천존' 신앙에서와 달리 뇌신과의 관계에 대한 설명을 찾아볼 수 없다. 마지막으로 '구천상제'와 '보화천존'의 도세법문을 비교해보면 첫째, 구천상제는 세상이 혼란, 불공평, 죄악에 빠졌기에 육신으로 인간 세상에 강림한 후 대순진리를 선포하였다. 이와 유사하게 보화천존도 천하와 인간세상을 순시하여 죄악과 겁액을 없앤다는 '순시천하(巡視天下)' 사상이 있다. 물론 여기에는 차이점이 존재하는데, 그 중 하나는 '보화천존'은 순시할 때 인간의 육신으로 화하지 않았다는 점이다. 또 다른 하나는 '보화천존'이 인간 세상에 창교의 방법을 통하여 선경을 건설하고자 하는 목표를 전해주지 않았다는 점이다. '보화천존'은 교리를 가르치거나 신통을 발휘하는 데에만 중점을 두고 있다. 둘째, '구천상제'가 내린 가르침인 해원상생은 후천선경을 건설하기 위한 수단과 과정이다. 도교의 '보화천존'도 인간이 지은 많은 죄악과 겁액은 세상 사람들이 맺은 원한과 관계가 있으므로, 이런 겁액과 죄를 해소하려면 해원부터 해야 한다는 것을 수차례에 걸쳐 언급하고 있다. 도교에서 말하는 '해원'의 구체적인 내용은 주로 인간의 시비, 질병, 겁액에 관한 것이며, 그 해결 방법으로는 주로 마음속으로 『옥추보경』을 읽는 것이다. 이를 '구천상제'의 '해원상생' 가르침과 비교하면 그 사상의 폭이나 깊이, 중요성, 이론적 측면 등에서 비교적 간단한 형태로서 체계적인 면모로까지 나아가지는 못하였다. 셋째, '구천상제' 는 곤경에 처한 사람이 신명의 호칭을 부르면 그에 상응하는 신명이 달려와서 구원해준다는 '소리감응' 방법을 사용하고 있는데, 이 방법은 도교의 '보화천존' 역시 사용하고 있는 것이다. 넷째, '구천상제'는 과오를 범한 사람이 자신의 과오를 뉘우치면, 그 다음에 상제의 용서를 받음으로써 그 원한이 풀리게 된다는 참법(懺法 : 懺悔法)을 세인(世人) 교화에 자주 사용하였다. 물론 이것은 해원상생의 구체적인 적용이라 할 수 있다. 기능면에서 보면 이 방법은 『구천응원뇌성보화천존옥추보참(九天應元雷聲普化天尊玉樞寶懺)』의 참의(懺儀)와 공통되는 점이 있다. 참의는 수도자 스스로 자신의 잘못을 뉘우치고, 수도에 정진하며, 사회의 안정을 도모하고, 포덕에 힘쓰고, 악을 물리치고 선을 널리 펼친다는 것인데, 이런 의미에서 양자는 일치한다고 생각된다. 필자가 생각하건대, 대순진리회의 '구천응원뇌성보화천존강성상제'와 도교의 '구천응원뇌성보화천존' 사이에는 공통점이 아주 많지만 동시에 차이점 또한 적지 않다. 만약 더욱 다양한 자료들을 수집하여 더욱 깊고 광범위한 연구를 진행한다면 한국 대순진리회와 중국 도교, 특히 도교의 뇌법종파(雷法宗派)와의 상관관계를 해석하는 데 큰 도움이 될 것이라 생각한다.

This study tries to review 'Sakuteiki(作庭記)', the Book of Garden Making, compiled at the end of the 11th Century during the Heian Period of Japan, from the East-Asian perspective. 'Sakuteiki' is a Garden Theory Book, the oldest in the world as well as in Asia, and it contains the traditional knowledge of Japanese ancient garden culture, which originated from the continent(Korea and China). Traditional knowledge related to East-Asian garden culture reviewed in this paper is "Fungsu Theory"(風水, Asian traditional ecology: Fengshui in Chinese; Fusui in Japanese), stemmed from the culture to seek sound and blessed places to live in. Viewed from modern landscape architecture, the Fungsu Theory corresponds to ecology(science). The Fungsu Theory was established around the Han Dynasty of China together with the Yinyangwuxing(陰陽五行) Theory and widely used for making human residences including gardens. It was transmitted to Japan via Korea as well as through direct transaction between Japan and China. This study reinterprets garden design principles represented in Sakuteiki, which were selected in 5 key words according to the Fungsu Theory. The 5 key words for the Fungsu Theory are "the place in harmony of four guardian gods(四神相應地)", "planting trees in the four cardinal directions", "flow of Chi(氣)", "curved line and asymmetry", and "mountain is the king, water is the people". Garden design principles of "the place in harmony of four guardian gods(四神相應地)" and "planting trees in the four cardinal directions" are corresponding to "Myeongdang-ron(明堂論, Theory of propitious site)". The place in harmony of four guardian gods mentioned in Sakuteiki is a landform surrounded by the flow of water to the east, the great path to the west, the pond to the south, and the hill to the north. And the Theory originated from Zhaijing(宅經, Classic of dwelling Sites) of China. According to this principle, the city was planned and as a miniature model, the residence of the aristocrat during the Heian period was made. At the residence the location of the garden surrounded by the four gods(the flow of water, the great path, the pond, and the hill) is the Myeongdang(明堂, the propitious site: Mingtang in Chinese; Meido in Japanese). Sakuteiki explains how to substitute for the four gods by planting trees in the four cardinal directions when they were not given by nature. This way of planting originated from Zhaijing(宅經) and also goes back to Qiminyaoshu (齊民要術), compiled in the 6th Century of China. In this way of planting, the number of trees suggested in Sakuteiki is related to Hetu(河圖) and Luoshu(洛書), which are iconography of Yi(易), the philosophy of change, in ancient China. Such way of planting corresponds to that of Yongdoseo(龍圖墅, the villa based on the principle of Hetu) presented in Sanrimgyeongje (山林經濟), an encyclopedia on agriculture and living in the 17th Century of Korea. And garden design principles of "the flow of Chi(氣)", "curved line and asymmetry" is connected to "Saenggi Theory(生氣論, Theory of vitality)". Sakuteiki explains the right flow of Chi(氣) through the proper flow and the reverse flow of the garden stream and also suggests the curved line of the garden stream, asymmetric arrangement of bridges and stones in the garden, and indented shape of pond edges, which are ways of accumulating Chi(氣) and therefore lead to "Saenggi Theory" of the Fungsu Theory. The last design principle, "mountain is the king, water is the people", is related to "Hyeongguk Theory(形局論, Theory of form)" of the Fungsu Theory. Sakuteiki explains the meaning of garden through a metaphor, which views mountain as king, water as the people, and stones as king's retainers. It compares the situation in which the king governs the people with the help of his retainers to the ecological phenomena in which mountain(earth) controls water with the help of stones. This principle befits "Hyeongguk Theory(形局論, Theory of form)" of the Fungsu Theory which explains landform on the analogy of social systems, people, animals and things. As above, major garden design principles represented in Sakuteiki can be interpreted in the context of the Fungsu Theory, the traditional knowledge system in East Asia. Therefore, we can find the significance of Sakuteiki in that the wisdom of ancient garden culture in East-Asia was integrated in it, although it described the knowhow of a specific garden style in a specific period of Japan.

With the increased development in downtown underground space facilities that vertically cross under a railway at a shallow depth, the demand for non-open cut method is increasing. However, most construction sites still adopt the pipe roof method, where medium and large diameter steel pipes are pressed in to form a roof, enabling excavation of the inside space. Among the many factors that influence the loosening region and loads that occur while pressing in steel pipes, the size of the pipe has the largest impact, and this factor may correspond to the magnitude of load applied to the underground structure inside the steel pipe roof. The super equilibrium method (SEM) has been developed to minimize ground disturbance and loosening load, and uses small diameter pipes of approximately 114 mm instead of conventional medium and large diameter pipes. This small diameter steel pipe is called an SEM pile. After SEM piles are pressed in and the grouting reinforcement is constructed, a crossing structure is pressed in by using a hydraulic jack without ground subsidence or heaving. The SEM pile, which plays the role of timbering, is a fore-poling pile of approximately 5 m length that prevents ground collapse and supports surface load during excavation of toe part. The loosening region should be adequately calculated to estimate the spacing and construction length of the piles and stiffness of members. In this paper, we conducted a comparative analysis of calculations of loosening load that occurs during the press-in of SEM pile to obtain an optimal design of SEM. We analyzed the influence of factors in main theoretical and empirical formulas applied for calculating loosening regions, and carried out FEM analysis to see an appropriate loosening load to the SEM pile. In order to estimate the soil loosening caused by actual SEM-pile indentation and excavation, a steel pipe indentation reduction model test was conducted. Soil subsidence and soil loosening were investigated quantitatively according to soil/steel pipe (H/D).

To construct a ship, blocks of various sizes must be moved and erected . In this process, lugs are used such that they match the block fastening method and various functions suitable for the characteristics of each shipyard facility. The sizes and shapes of the lugs vary depending on the weight and shape of the block structures. The structure is reinforced by welding the doubling pads to compensate for insufficient rigidity around the holes where the shackle is fastened. As for the method of designing lugs according to lifting loading conditions, a simple calculation based on the beam theory and structural analysis using numerical modeling are performed. In the case of the analytical method, a standardized evaluation method must be established because results may differ depending on the type of element and modeling method. The application of this ambiguous methodology may cause serious safety problems during the process of moving and turning-over blocks. In this study , the effects of various parameters are compared and analyzed through numerical structural analysis to determine the modeling conditions and evaluation method that can evaluate the actual structural response of the lug. The modeling technique that represents the plate part and weld bead around the lug hole provides the most realistic behavior results. The modeling results with the same conditions as those of the actual lug where only the weld bead is connected to the main body of the lug, showed a lower ulimated strength compared with the results obtained by applying the MPC load. The two-dimensional shell element is applied to reduce the modeling and analysis time, and a safety working load was verified to be predicted by reducing the thickness of the doubling pad by 85%. The results of the effects of various parameters reviewed in the study are expected to be used as good reference data for the lug design and safe working load prediction.

This study has been carried out to estimate mean concentration and the daily intake of 2 artificial sweeteners (aspartame and sucralose) by analyzing food samples. Total number of samples was 755 and the number of samples detected for sweeteners was 33 (detection rate was 4.4%). Contribution rate to total estimated daily intake (%) of artificial sweeteners in food categories was high in candy for aspartame and sucralose. Total Estimated Daily Intakes $({\Sigma}EDI)$ for different age groups were high in $13{\sim}19$ years old for aspartame and $7{\sim}12$ years old for sucralose. Total estimated daily intakes $({\Sigma}EDI)$ of men and women were 5.10 mg/person/day and 4.88 mg/person/day, respectively. Total estimated daily intakes $({\Sigma}EDI)$ of artificial sweeteners were shown as follows; 3.75 mg/person/day for aspartame and 1.27 mg/person/day for sucralose, respectively and assuming a body weight of 55 kg. These values were ranged from $0.15{\sim}0.17%$ of acceptable daily intake (ADI) evaluated by FAO/WHO and $1.0{\sim}21.4%$ of theoretical maximum daily intake (TMDI), and therefore, judged to be safe.

This study predicted the probability of corrosion initiation of reinforced concrete tunnel boxes structures using the Monte Carlo Simulation. For the inner wall and outer wall in the tunnel boxes, exposed to airborne chloride ion and seawater directly respectively, statistical values of parameters like diffusion coefficient D, surface chloride content $C_s$, cover depth c, and the chloride threshold level $C_{lim}$ were examined from experiment or literature review. Their average values accounted for $3.77{\times}10^{-12}m^2/s$, 3.0% by weight of cement, 94.7mm and 45.5mm for outer wall and inner wall, respectively, and 0.69% by weight of cement for D, $C_s$, c, and $C_{lim}$, respectively. With these parametric values, the distribution of chloride contents at rebar with time and the probability of corrosion initiation of the tunnel boxes, inner wall and outer wall, was examined by considering time dependency of chloride transport. From the examination, the histogram of chloride contents at rebar is closer to a gamma distribution, and the mean value increases with time, while the coefficient of variance decreases with time. It was found that the probability of corrosion initiation and the time to corrosion were dependent on the time dependency of chloride transport. Time independent model predicted time to corrosion initiation of inner wall and outer wall as 8 and 12 years, respectively, while 178 and 283 years of time to corrosion was calculated by time dependent model for inner wall and outer wall, respectively. For time independent model, the probability of corrosion at 100 years of exposure for inner wall and outer wall was ranged 59.5 and 95.5%, respectively, while time dependent model indicated 2.9 and 0.2% of the probability corrosion, respectively. Finally, impact of $C_{lim}$, including values specified in current codes, on the probability of corrosion initiation and corrosion free life is discussed.
