Objective: This research aimed to explore the changes in the observed abdominal sagging index (ASI) and reproductive performance of Roman male and female geese during the breeding period. Methods: The 339 six-month-old breeding geese (109 male; 230 female) were used in this study, in which five male and five female geese were slaughtered on a monthly basis to record the ASI. Results: The short diameter of the testes of the male goose when the female goose lays eggs and in the second, third, and fourth months was significantly wider than in the fifth months (19.0, 20.8, 21.4, and 19.6 vs 12.7 and 14.0 mm/bird; p = 0.0105). On the other hand, the testicular weight of the male goose in the second and third months after the female goose lays eggs was significantly higher than that in the second and fifth months after laying (0.33% and 0.37% vs 0.11% and 0.19%; p = 0.0212). During the exploring period, the length and weight of the fallopian tube, the weight of the ovary, the number of follicles in 2 to 3 cm, the number of follicles in 3 to 4 cm, the fallopian tube weight in the carcass weight percentage, and the ovary weight in the carcass weight percentage all demonstrated a significant curve response. Further, female ASI was positively correlated with reproductive tract length (r = 0.815; p<0.05) and egg production per female (r = 0.790; p<0.05). Conclusion: The ASI classification method is more objective and easy to distinguish. This scoring method has a high correlation with the number of eggs laid by each goose and the length of the reproductive tract, inferring that the goose observation could take advantage of ASI during egg-laying and can predict the reproductive system development during the laying period and determine when the breeding goose begins to lay eggs.

The most important bases of maritime laws in China are laws enacted by Constitution, a legislative institution of National People's Congress and Legislation of NPC Standing Committee. However, in reality, the institution, which become the basis of Chinese marine policy and leads overall maritime affairs, is a State Council of the Chinese central government and many objects of our researches on Chinese marine policy and laws are composed centering on this administration law. Therefore, in understanding Chinese maritime laws, it becomes an important prerequisite to understand relevant laws (statutes), administration law, statutes of local province, mutual authority relationships of these legislative institutions, and interpretation authority regarding laws (statutes). In May 2003, Chinese State Council ratified and declared ${\ll}$Guideline of the national maritime economic development plan${\gg}$ and this is the first macroinstructive document enacted by the Chinese government for promoting maritime economy in integration development. This plan guideline shows very well a new policy and deployment direction of maritime policy in China. China is already striving to lead its maintenance stage of domestic legislation into a new stage under the UN maritime laws agreement system and this is an expression of intention to take national policy regarding the ocean as a new milestone for the national economy through concurrent developments in various fields such as national territory, economy, science technology, national defense, and maritime biology. In this point, Chinese maritime policy and maritime legislation provide lots of indexes of lessons in many parts. In particular, regarding Korea, which has to solve many issues with China in Yellow Sea, East China Sea, and Balhae, we have to realize that we can maximize national interest only with a systematic approach to research on changes of domestic policies and maritime legislation within China. In addition, in understanding Chinese maritime related laws, we have to realize it is an important task to not only understand legislative subjects for mutual creation of order within the entire frame of law orders of China but also to predict and react to direction of policy of Chinese domestic legislation through dynamics of these subjects.

Seismic isolation and vibration control techniques have been developed and put into practical use by challenging researchers and engineers worldwide since the latter half of the 20th century, and after more than 40 years, they are now used in thousands of buildings, private residences, highways in many seismic areas in the world. Seismic isolation and vibration control structures can keep the structures undamaged even in a major earthquake and realize continuous occupancy. This performance has come to be recognized not only by engineers but also by ordinary people, becoming indispensable for the formation of a resilient society. However, the dynamic characteristics of seismically isolated bearings, the key elements, are highly dependent on the size effect and rate-of-loading, especially under extreme loading conditions. Therefore, confirming the actual properties and performance of these bearings with full-scale specimens under prescribed dynamic loading protocols is essential. The number of testing facilities with such capacity is still limited and even though the existing labs in the US, China, Taiwan, Italy, etc. are conducting these tests, their dynamic loading test setups are subjected to friction generated by the large vertical loads and inertial force of the heavy table which affect the accuracy of measured forces. To solve this problem, the authors have proposed a direct reaction force measuring system that can eliminate the effects of friction and inertia forces, and a seismic isolation testing facility with the proposed system (E-isolation) will be completed on March 2023 in Japan. This test facility is designed to conduct not only dynamic loading tests of seismic isolation bearings and dampers but also to perform hybrid simulations of seismically isolated structures. In this paper, design details and the realization of this system into an actual dynamic testing facility are presented and the outcomes are discussed.

The digitization of traditional medical knowledge in Tanzania will greatly enhance its preservation and dissemination. This is especially important given the challenges facing the current methods of preserving and managing such knowledge. This study presents the requirements engineering approaches and requirements for a web-mobile application that would successfully digitize indigenous knowledge of phytomedicine and relevant practitioners licensing and registration processes. To establish the requirements of such a digital system application, the study sought the opinion of 224 stakeholders whose suggestions were used to analyze and model the requirements for designing such a web-mobile tool. The study was carried out in Arusha, Kagera and Dar es Salaam regions of Tanzania which involved ethnobotanical researchers, herb practitioners, curators from herbaria and registrar officers from Traditional and Alternatives Health Practice Council. Structured interview, survey, observation and document review were employed to find out the basic functional and non-functional requirements for possible designing and implementation a web-mobile application that would digitize indigenous knowledge of medicinal plants. The requirements were modelled using the use case and context diagrams. Finally, the study came up with a list of items for both functional and non-functional requirements that can be used as guidelines to develop a web-mobile application that will capture and document traditional medical knowledge of medicinal plants in Tanzania and, enabling relevant authorities to regulate and manage stakeholders.

Icariside II, a flavonol glycoside, was isolated from the aerial part of Epimedium Koreanum Nakai by the anti-hepatotoxic acitivity guided fractionation technique employing $CCl_4-in-toxicated$ primary cultured rat hepatocytes as an assay system. Its anti-hepatotoxic activity was evaluated by measuring activity of glutamic pyruvic transaminase released from the $CCl_4-in-toxicated$ primary cultured rat hapatocytes. Icariside II significantly reduced the activity of glutamic pyruvic transaminase released from the $CCl_4-in-toxicated$ primary cultured rat hepatocytes and resulted in 78% recovery of the toxicity at the concentration of $200{\;}\mu\textrm{m}$. The anti-hepatotoxic activity of icariside II on the $CCl_4-in-toxicated$ primary cultured rat hepatocytes was as potent as that of silybin.

Several algorithms for nuclear power plant (NPP) break event detection, isolation, localization, and size estimation are proposed. A break event can be promptly detected and isolated after its occurrence by simultaneously monitoring changes in the sensing readings and by employing an interquartile range-based isolation scheme. By considering the multi-sensor data block of a break to be rank-one, it can be located as the position whose lead field vector is most orthogonal to the noise subspace of that data block using the Multiple Signal Classification (MUSIC) algorithm. Owing to the flexibility of deep neural networks in selecting the best regression model for the available data, we can estimate the break size using multiple-sensor recordings of the break regardless of the sensor types. The efficacy of the proposed algorithms was evaluated using the data generated by Maanshan NPP simulator. The experimental results demonstrated that the MUSIC method could distinguish two near breaks. However, if the two breaks were close and of small sizes, the MUSIC method might wrongly locate them. The break sizes estimated by the proposed deep learning model were close to their actual values, but relative errors of more than 8% were seen while estimating small breaks' sizes.

승선 환경의 폐쇄성과 이사회성, 선내 규율의 엄격함 등으로 청년들은 선원직을 기피하고 있다. 우리나라는 승선근무예비역제도라는 특수한 제도가 존재해 청년들을 선원직으로 유인하고 있지만, 이 제도마저 존립이 위태롭다. 최근의 선원 고용유형은 선박관리회사로부터 고용되어 선사에 파견되는 비정규직 형태가 대부분이다. 선박관리회사(SM)와 선원 간에 임시 고용계약을 맺고, SM이 선사에 선원을 파견하는 비정규직 고용형태가 유행하고 있다. 선원직 매력도가 떨어지고 있는 상황에도 2018년 발표된 국가 해운재건 5개년 계획에는 선박과 화물의 확보 방안만 담겨 있다. 이 논문의 핵심 내용은 이항로짓모형을 이용해 선원의 고용형태 결정요인을 분석하는 것이다. 분석 결과, 선원의 최종학력이 고용형태를 결정하는 요소로 나타난 반면, 소속선사 유형, 승선 선종, 소속 선박관리회사 유형, 근무 분야, 해기사 면허 소지 여부 등은 선원 고용형태 결정에 유의미한 변수가 아닌 것으로 나타났다.
