Morphology and histochemical characteristics of the alimentary tract in surfperch, Ditrema temmincki were investigated by histological observation. The relative length of gut(RLG) in surfperch, that is the postpharyngeal portion of the alimentary tract, is about 0.89 to standard length. The absence of a stomach, which is the part of expantion of the alimentary tract between esophageal end and the entrance of the bile duct into the intestine, was observed. The alimentary tract is divided into the esophagus, esophageal-intestine part, anterior intestine, mid intestine, posterior intestine, intestinorectum part, rectum, rectal-anus part, and anus by morphology and histochemical features. Morphology of mucosal folds is the most complexity in the rectum and the tunica muscularis of the esophagus and anus is more advanced than those of other parts. The epithelial layers of mucosal folds consist of columnar epithelium except for cuboidal cells of the anterior part of the esophagus. The goblet cells and polysaccharide absorptive cells were observed in the alimentary tract. Nutritive polysaccharide is mainly absorbed by the absorptive cells in the posterior intestine of the surfperch.

This study addresses and examines differences in firm value after tax audits by the Korean Internal Revenue Service. Tax audits can potentially depreciate a firm's value due to the mass cash outflow that often results from the additional tax charges involved. However, tax audits that reveal negative aspects of a business, such as excessive entertainment expenses, fraudulent accounting, or inappropriate business practices, may have positive effects on a firm's value, as the monitoring involved can improve accounting transparency and reduce agency costs. This study shows that there is typically an increase in a firm's value in the year after a tax audit has been conducted, in comparison with the previous year. This result suggests that firm value can increase after a tax audit is conducted, despite the possible value depreciation resulting from a mass cash outflow.

With the advancement of AI technology, legal status and regulation issues for AI robots, and the necessity of a robot registration system are emerging. Since the shape and activity area of AI robots will no longer be limited to hardware in one country, the definition and regulation of AI robots should be expanded to a comprehensive concept including software, and information about them should be securely managed and shared by governments around the world. From this perspective, we extend 'AI robot' to the concept of Juridical AI encompassing hardware and software, and propose a method to operate the Juridical AI registration system using a permissioned blockchain called Juridical AI Chain. Since blockchain is an internationally distributed database, operating such AI registration system based on the blockchain will be a way to effectively cope with the global problems caused by the commercialization of AI robots.

Stability of resistance of the two-spotted spider mite (Tetranychus urticae) to dicofol was investigated. Resistance level (23.0-fold) of adult females to dicofol was kept up to 1 year without selection by dicofol, but was decreased to 15.8-, 10.7-fold after 2 and 3 years, respectively. Susceptibility of adult females obtained from reciprocal crosses $(R_{female}\timesS_{male},R_{male}\times S_{female})$ of the R and S stains to dicofol was declined by the success of generation.

To deepen the understanding of shear behaviour in beams without transverse reinforcement, the relative importance of five contributing factors to concrete shear resistance($v_c$), which are i)flexural compression zone, ii)friction at crack faces, iii)dowel action, iv)arch action and recently identified, v)residual tensile stresses across cracks, was explained physically using two analytical methods based on the truss concept. One is called "Modified Compression Field Theory(MCFT)" considering ii) and v) explicitly, and the other "Crack Friction Truss Model(CFTM)" more dominantly ii) in determining concrete resistance. To verify their effectiveness, the predictions using MCFT and CFTM were also made for twenty KAIST beam tests($f'_c$=53.7Mpa), designated more likely to the development of the size effect law based on the fracture mechanics concept. Experimental findings with varying of a/d, longitudinal reinforcement ratios, and obtained from MCFT enabled additional explanations for some phenomena which were difficult to measure in tests. However, MCFT seemed somewhat conservative for beams with higher longitudinal reinforcement, while somewhat unsafe for beams with larger depths. More tests are necessary leading to firm conclusions in these areas.

Recently, twin-tunnel is often designed in the aspects of disaster prevention and economical reasons. However, the design cases and the studies are relatively insufficient. By the twin-tunnel excavation, deviate stresses of pillar between tunnels are increased and the increased stresses induce the instability of the twin-tunnel. In this study, numerical analyses about the twin-tunnel behaviour were conducted with varying ground strength, width of pillar and depth of earth cover and a series of regression analyses were carried out by using the results of numerical analyses for the twin-tunnel. Based on the numerical analyses, an estimation method of derived stresses is suggested through the regression analyses. Also, based on the results of regression analyses, an quantitative estimation method considering the reinforcement effects is also suggested. Then various parametric studies were conducted to be considered the reinforcement type and various design parameters. Finally, the efficiency of the suggested method based on the Hoek-Brown Failure Criterion is verified through the results of parametric studies.

Purpose: The purpose of this study was to analyze the prevalence and consequences of verbal abuse in the operating room nurses by physicians and other nurses. Method: The data were collected from 761 operating nurses. The period of data collection was from September 7 to November 25, 2004. For this study the following tools were used: the verbal abuse scale, the emotional stress scale and the long-term negative effect scale. The data were analyzed by using SPSS Win 11.5. Result: 744 nurses reported experiencing some type of verbal abuse from a physician and other nurses. The emotional stress and long-term negative effect were significantly increased by verbal abuse. The nurses of less than one year increased emotional stress from verbal abuse. The physician was the most frequent source of emotional stress by verbal abuse, followed by other nurses. The long-term negative effect was significantly increased in the factors of emotional stress and the physician was the most frequent source than other nurses. Conclusion: Verbal abuse of nurses by physicians and other nurses continues to exist and is associated with negative consequences. Nurse administrators have to assess the present state for workplace verbal abuse and must endeavor in order to reduce verbal abuse.

아건강상태(亞健康狀態)에 처하여 있는 환자는 양의학적으로 뚜렷한 병리적 변화를 찾아보기가 쉽지 않다. 그러나 중의학의 병기이론을 근거로 하면 아건강상태(亞健康狀態)는 일정한 병리적 상태에 처한 것으로 인식된다. 즉 인체의 음양과 기혈이 편파(偏頗)되어 있으며 단지 그 변화가 초기단계에 있기 때문에 병태(病態)적 요인에 비하여 정도(程度)적인 차이가 있는 것으로 인식된다. 중의학이 건강에 대한 인식은 ‘천인상응(天人相應)’과 ‘음평양비(陰平陽秘)’, ‘정신내치(精神乃治)’란 관념이다. 주로 사람과 자연환경 및 외부사회간의 상호관계, 그리고 체내의 음양조화를 이룬 동태평형(動態平衝)을 중요시한다. 즉 인체의 기혈평형과 장부기능의 협조(協調)를 강조하고 기기(氣機)의 조창(調暢)이 건강의 근본(根本)이라고 인식한다. 시대적인 관계로 중의학에는 아건강상태(亞健康狀態)란 용어가 없지만 2000여년 전(前)에 성서(成書)된 중의학의 경전거작(經典巨作)인 ${\ulcorner}$내경(內經)${\lrcorner}$ 속에 일찍이 ‘미병(未病)’이란 개념(槪念)과 치미병(治未病)의 관념을 제출하였다. 이는 중의학이 미병선방(未病先防)의 의학사상을 나타내었고 주로 치병지미성(治病之未成), ‘치기미전(治其未傳)’, ‘차후방복’등 세 가지 방면의 내용을 제시된다. 또한 중의학은 양생학(養生學)에 대하여 특별히 중시하였고,${\ulcorner}$내경(內經)${\lrcorner}$에 대량(大量)의 편폭(篇福)으로 어떻게 양생하고 정기(正氣)를 보호해야 한다는 방법이 소개 되어 있다. 후세(後世) 역대의가(歷代醫家)는 그 내용을 더욱 충실(充實)케 하고 발전시켰다. 근대(近代)에 이르러서 중의학술(中醫學術)에 특유한 내용인 '미병학(未病學)'이 형성되었고, 그 이론체계 속에 아건강상태(亞健康狀態)의 예방과 치료에 관한 내용이 포함되어 있다.

Objectives : I'd like to introduce a Korean medical scientist, Lee Gyoojoon (李圭晙, 1855-1923)'s achievements about Huangdi's Internal Classic (黃帝內經, HIC) to examine the Section of Viscera and Bowels to inspect the Medical Classics (稽經藏府篇, SVBIM) of the Double grinded Medical Mirror (醫鑑重磨, DMM), which is a medical book published in 1922, his last studies. And I'd like to describe its meaning of medical history. Methods : For this, I compared the DMM with two primary texts, the representative medical books of Joseon dynasty, Treasured Mirror of Eastern Medicine (東醫寶鑑, TMEM) and Lee's former research result of HIC, Major Essentials of Huangdi's Internal Classic Plain Question (黃帝內經素問大要, MEHIC), in the aspects of the original text, annotation, editing, attached theses, and so on. Results : Lee Gyoojoon criticized the TMEM in two aspects. First, it was unfocused and miscellaneous, second, it intended to help Yin Qi (陰氣) and reduce Yang Qi (陽氣) so that it regards a prime mover, Yang Qi, as an enemy. In order to solve these problems he deleted miscellaneous articles and sort out the points to accord with the HIC. As a result, he had written the Section of SVBIM of the DMM in the form of revising the subtitles or refuting the contents of TMEM and quoted the partial texts of MEHIC to be written by the view of Supporting Yang Qi (扶陽). Conclusions : Lee Gyoojoon proposed the Supporting Yang Qi medicine to preserve the Heart fire (心火) based on his lifelong Neo-Confucianism (性理學) study. The Section of SVBIM of the DMM showed how to apply his medical theory, which is achieved by the study of the medical classic HIC to real clinical medicine through a medium of the TMEM. In addition, it could explain concretely how the Confucianists studied the medicine and how Confucianism can impact to the development of medical theory.

Objectives : The goal of this paper is to research what affected diagrams of liver originated from Mingtangzangfutu while they were changed. Methods : Diagrams of liver in Traditional Chinese and Japanese medical books had been gathered as many as possible. After they were divided into ones which were originated from Mingtangzangfutu and the others, diagrams originated from Mingtangzangfutu, were again classified into 4 filiations according to Huang Longxiang(黃龍祥)'s standard. Apart from his classification, they were analysed by 4 form factors, e.g. shape, number, veins and petiole of leafs. Results : Reliability of this methods had been confirmed by the correspondence with Huang's 14 standard books, before 29 diagrams of liver were derived from 33 books including 13 books that Huang had already suggested. The lobes of liver in most of diagrams resembled 7 lanceolate or long oval leafs, or a maple leaf with 6 indentations, 4 left lobes and right 3 ones. In most of diagrams, veins of leafs were described variously, and petioles of leafs were drawn more shortly or longer. Analysing 29 diagrams by 4 form factors proved that Huang's classification had crossing features among 4 filiations. This phenomenon implied the painters or doctors drawing diagrams might not convince if the shape of liver was correct or not. Although veins and petiole of leafs in diagrams of liver could be compared with tissues in liver in modern human anatomy, diagrams were not been affected by dissection from Yuan(元) to middle Qing(淸) dynasty. Conclusions : Lingshu(靈樞), Nanjing(難經) and Wang Bing would had constantly acted on 29 diagrams of liver, since diagram of liver originated from Mingtangzangfutu, appeared first in Zhenjiujuying(鍼灸聚英). But they did not come from dissection during same periods.
