It is obviously true that the aspects of interior designs in current use have been combined with changing trends and developed and handed down throughout centuries. An examination of respective characteristics of spaces where Korean presidents have lived during their terms of office could get a useful clue by which both traces of Korean modernism and senses of modeling can be perceived. However, there are not enough literatures that can be verified. Therefore, it would be especially meaningful to find out and analyze documents unearthed. The purpose of this study is to consider the expressiveness of interior designs of presidential residence and office which have been combined with changing trends and developed, while classifying respective cases during presidential tenure by periods of Joseon Government general, U. S military administration, the first Republic, the second Republic, the third and the fourth Republic, the fifth Republic, and the sixth Republic, examining relevant literatures, photos, drawings and making on-the-spot survey. The study is also intended to get a better understanding of the aspects and the features of interior designs shown in presidential residences and offices that are not so much made known due to uneasy access to archives and to document the resources buried in oblivion and to consider the historical meanings.

Now, the conservation policy of historic environments in Korea which started in early 1980's, is in a danger. In addition, because of economic crisis started last year, the concerns for historic environments are growing weaker. However, this situation can be a good opportunity to prepare for the coming conservation works, The purpose of this study is to find clues for conservation of historic environments by considering foreign precedents. For concrete results, this study selects historic rural settlements as a case and focuses on the relationship among related people in the light of the their rights. Based on the consideration of foreign precedents, three different characters in the conservation process could be identified compared with korean cases; 1) Except partial works of public sector, generally the conservation process is under the control of nonprofit groups and residents themselves, 2) Conservation methods include with the proper change process for the sustainable settlement, and avoid the unconditional past-oriented approach, 3) Conservation methods are composed of not only the preservation of external forms such as assets but also the continuous participation and management of the community. And the most important clue which has been extracted is that the diverse rights of related people in the historic rural settlements should be kept in balance thoroughly.

토지이용변화는 환경 변화에 영향을 주는 대표적인 인자이기 때문에 수문 모델링에 있어서 상당히 중요하다. 특히 급격한 도시화가 이루어지는 지역에 대해서는 토지이용변화를 반드시 고려하여야 한다. 인구와 지형자료를 이용하여 토지이용변화를 모의할 수 있는 CLUE-S 모델이 개발되었지만 아직까지 대부분 수문모델은 토지이용변화를 고려하지 못하고 있었다. 이에 Pai, N. 와 D. Saraswat은 SWAT2009_LUC Tool를 개발하여 시공간적으로 변화하는 토지를 고려한 수문모의를 가능하도록 하였다. 하지만 SWAT2009_LUC는 새로운 종류의 토지이용종류를 고려할 수 없어 유역 내 새로운 토지이용도가 추가될 시 이를 모의할 수 없다는 단점을 가지고 있다. 이러한 단점을 극복하기 위해서 Friedrich J. Koch Koch는 Land use Update and Soil Assessment(LUPSA)를 개발하여 새로운 토지이용도 및 변화된 토지이용도의 경사도를 추가적으로 고려할 수 있도록 하였다. 하지만 LUPSA 모듈은 공개되어 있지 않다. 따라서 본 연구에서는 SWAT 사용자들이 토지이용변화를 많이 고려할 수 있도록 Web 기반의 LUC 모듈을 개발하였으며, SWAT BFlow Alpha Factor와 경사도 기반의 CN을 산정할 수 있는 모듈을 추가하였다. 본 연구에서 개발된 Web 기반의 LUC는 국내뿐만 아니라 해외 SWAT 사용자들로 하여금 급격하게 토지가 변화한 유역에 대해 정확한 수문모의를 하는데 기여할 것이라 판단된다.

Posterior interosseus (PI) nerve compression is a rare form of compressive neuropathy. It can cause pain along the radial nerve course and weakness of radial nerve innervating muscles without sensory symptoms. A 65-year-old man visited our institution complaining weakness of finger extension and thumb abduction after 2 times of injections at the right elbow in local clinic. The patient's clinical history and physical examination implied an iatrogenic radial nerve injury caused by the injection. The electrophysiologic study revealed of posterior interosseus neuropathy (PIN) with incomplete conduction block. However, the ultrasound study showed that the PI nerve was compressed by an anechoic cyst. The magnetic resonance imaging also confirmed of a ganglion cyst, not a hematoma. After repeated aspirations and a steroid injection, the electrophysiologic study showed recovery of motor weakness. Despite of the clue which implying an iatrogenic injury, clinician should consider other possibilities such as ganglion cysts and ultrasound guided aspiration and steroid injection could be an effective option for conservative management.

Recently, Chang et at.$^[9]$ proposed a new password-based key agreement protocol and a password change protocol to improve the efficiency in the password-based authenticated key agreement protocol proposed by Yeh et at.$^[8]$. However, Wang et al.$^[10]$ showed that their protected password change protocol is not secure under the denial of service attack and the dictionary attack This paper proposes an improved password change protocol to solve this problems in the Chang et al's protocol. In the proposed protocol, the format of communication messages is modified not to have any clue for the guessing of the password and verifying of the guessed password. The proposed protocol supports the advantages in the previous password-based protocols and solves the problems in them effectively.

In an environment in which a limited type and number of sensors are used, a demand for acquiring various context information may appear. In this study, a new method for acquiring various context information than before was proposed in an environment in which a limited number of sensors are required. To this end, a clue was obtained from the Exon-Intron theory, which is gaining great interest in the field of biology, and a method for acquiring various context information was proposed based on this. By applying Exon-Intron's selective cutting and combining method, events of each sensor were efficiently cut and each event data was combined and utilized, thereby realizing the diversification of the acquired context information.

Background: Bees and flowering plants associations were initially began during the early Cretaceous, 120 million years ago. This coexistence has led to a mutual relationship where the plant serves as food and in return, the bee help them their reproduction. Animals pollinate about 75% of food crops worldwide, with bees as the world's primary pollinator. In general, bees rely on flower scents to locate blooming flowers as visual clue is limited and also their host plants from a distance. In this review, an attempt is made to collect some relevant 107 published papers from three scientific databases, Google Scholar, Scopus, and Web of Science database, covering the period from 1959 to 2021. Results: Flowering plants are well documented to actively emit volatile organic compounds (VOCs). However, only a few of them are important for eliciting behavioral responses in bees. In this review, fifty-three volatile organic compounds belonging to different class of compounds, mainly terpenoids, benzenoids, and volatile fatty acid derivatives, is compiled here from floral scents that are responsible for eliciting behavioral responses in bees. Bees generally use honest floral signals to locate their host plants with nectar and pollen-rich flowers. Thus, honest signaling mechanism plays a key role in maintaining mutualistic plant-pollinator associations. Conclusions: Considering the fact that floral scents are the primary attractants, understanding and identification of VOCs from floral scent in plant-pollinator networks are crucial to improve crop pollination. Interestingly, current advances in both VOCs scent gene identification and their biosynthetic pathways make it possible to manipulate particular VOCs in plant, and this eventually may lead to increase in crop productivity.

Aesthetics of use for modern people can be regarded as being weighted toward universal and rational function since it has focused on an 'automation and efficiency' and 'smartness' in terms of technological and human engineering position. Thus, aesthetics of use as an individual agent has remained in minimal level. This study attempts to seek conceptual model of design regarding the behavior of users from the systematization of critical theories about the usability. To do that, 'HERTZAIN TALES' written by Anthony Dune and the concept and system of Droog Design have been used as a core standard. In line with the various experiments by artist groups such as Fluxus, Memphis group and the work of product semantics, and inherent characteristics of Droog design, which has surfaced from the 1990s, concepts that has mentioned in the Hertzain tales have been organized into main texts. By overcoming cognitive bias inherent in the material culture and by overcoming an existing usability based on immateriality and dialectic solution, the autonomy of critical design and instrumentality of Droog design have been systemized. By interpreting the design aspect of 12 pieces that have been submitted to the RE;MIND section, the core of this study, it has been confirmed that conceptual and critical design's aesthetics of use From the interpretation of the design aspect of 12 pieces that have been submitted to the RE;MIND section, the core of this study, it has been confirmed that conceptual and critical design's aesthetics of use has established the autonomy and independence of the behavior of users, created functional articulation of materials and secured new conceptual model and thus, could be an effective methodical clue for creating an emergent design.

The objective of this article is to induce that the conception of 'Qi-jul(氣質) and Qi-pum(氣稟)' was introduced to the Sasang(四象) Constitutional Medicine from bibliographic study on the theory of 'Qi-pum(氣稟)'. The conclusions summerized as followings. 1. In the oriental medicine, qualitative difference of 'zheng-qi(正氣)' among the individuals, the opposing power against a disease, is regarded as constitution. Having been used as 'nature(素)', 'quality(質)' and 'character(氣質)' in the oriental medical book, the word of 'Che-Jil(體質)' was used in good earnest at the end of 'Qing(情)' dynasty. 2. The nature(性) is divided into two, original nature(本然之性) and charicteristic nature(氣質之性) in the 'New confucianism(新儒學)' and the former means a principle(理), is a pure and good thing and used as a conception of universality, the latter is a principle of character and a imperfect imitation of principle(理). 3. It was repeatedly confirmed that 'Qi-jil and Qi-pum' meant the difference among the individuals by the dispute of 'Li-Qi(理氣)' caused by Lee Hwang(李滉) and Lee Yi(李耳) and by that of 'Ho-Rak(湖洛)' in the Ch'o-son(朝鮮) dynasty. 4. Han Sok-Ji, based on Meng-Zi(孟子)'s doctrine that man's inborn nature is good, criticized the theory of 'Qi-pum' which was 'Zhu-Zi(朱子)'s opinion and his opinion about the life(命) was thought to clue to the classification of the 'Sasang(四象)' invented by Lee Je-Ma as Park Se-Dang's theory that everyone has common nature but has different life(命). 5. By introducing the theory of 'Qi-pum' and the conception of life(命) which was understood as a special character by Han Sok-Ji and Park Se-Dang to Sa-sang constitutional medicine, Lee Je-Ma explained the reason why each man who was classified four constitutions, 'Taiyang'(太陽), 'Taiyin'(太陰), 'Shaoyang'(少陽), 'Shaoyin'(少陰), had the different formation of the visceral department(臟局).

Background: Studies of morphological variation within and among populations provide an opportunity to understand local adaptation and potential patterns of gene flow. To study the evolutionary divergence patterns of Schlegel's Japanese gecko (Gekko japonicus) across its distribution, we analyzed data for 15 morphological characters of 324 individuals across 11 populations (2 in China, 4 in Japan, and 5 in Korea). Results: Among-population morphological variation was smaller than within-population variation, which was primarily explained by variation in axilla-groin length, number of infralabials, number of scansors on toe IV, and head-related variables such as head height and width. The population discrimination power was 32.4% and in cluster analysis, populations from the three countries tended to intermix in two major groups. Conclusion: Our results indicate that morphological differentiation among the studied populations is scarce, suggesting short history for some populations after their establishment, frequent migration of individuals among the populations, and/or local morphological differentiation in similar urban habitats. Nevertheless, we detected interesting phenetic patterns that may predict consistent linkage of particular populations that are independent of national borders. Additional sampling across the range and inclusion of genetic data could give further clue for the historical relationship among Chinese, Japanese, and Korean populations of G. japonicus.
