화장품의 변질요인은 크게 물리적 또는 화학적 변화에 의한 요인과 미생물오염으로 인한 각종 문제점으로 대별될 수 있다. 이 중에서 미생물 오염문제는 제품의 상품가치에 미치는 영향 뿐만 아니라 지속적인 사용에 의한 피부의 위생적 측면때문에 그 중요성에 대한 인식이 높아지고 있다. 따라서, 제품개발시는 화장품 처방중의 영양성분의 배합, pH, 유화형태, 방부제의 혼합, 분배계수 및 그 안정성을 고려하여야 함은 물론이고 처방중의 모든 원료의 각각에 대한 항균능 및 피부자극여부를 사전에 미리 조사하여 각 제품별로 적당한 방부체계를 선택하는 것은 매우 중요한일이다. 독성실험방법에 있어서 in vivo 실험에 대체할 수 있는 새로운 in vitro 실험방법 수립 즉, 동물실험을 하지 않고 in vitro 실험결과로부터 in vivo 결과를 예측할 수 있도록 새로운 in vitro 실험체계의 가능성을 실험하였다. 4종의 cell line중 transformed mouse fibroblast L929가 본 실험에서 사용하기에 배양상의 용이성과 안정성, 재현성의 관점에서 가장 알맞은 cell line이었다. transformed mouse fibroblast L929를 사용한 NR$_{50}$ assay와 Draize score간의 regression coefficient ${\gamma}$값은 0.91이었다. 혈청은 시험물질의 세포에 대한 민감성에 영향을 주었다. 따라서, modified serum-free method를 이용함으로써 regression coefficient가 증가된 즉, 상관성 및 재현성이 높은 결과를 얻을 수 있었다. 이러한 기술은 독성실험에 실험동물을 사용하지 않고 in vivo test에 대체 할 수 있고, 또한 화학물질에 대한 prescreening으로 이용할 수 있을 것으로 판단된다.원과 섭식장소, 수중생물의 경우는 특히 수온, 수량 영양원등이다.(중략). 본 연구의 접근방법으로는 ASRS의 개념적인 Reference Model을 수립하고 이 Reference Model에 대한 Formal Model로 DEVS(Discrete Event System Specification)을 이용하여 시스템을 Modeling하였다. 이의 Computer Simulation을 위하여 DEVS형식론 환경에서의 Simulation Language인 DEVSim ++ⓒ를 이용하여 시스템을 구현하였다.. 실형 결과로는 먼저 선형 상미분방정식의 예로 mass-damper-spring system, 비선형 상미분방정식의 예로는 van der Pol 방정식, 연립 상미분방정식의 예로는 mixing tank problem 등을 보였으며, 그의 공학에서 일어나는 여러 가지 문제들도 다루었다.화물에 대한 방어력이 증가되어 나타난 결과로 여겨지며, 또한 혈청중의 ALT, ALP 및 LDH활성을 유의성있게 감소시키므로서 감잎 phenolic compounds가 에탄올에 의한 간세포 손상에 대한 해독 및 보호작용이 있는 것으로 사료된다.반적으로 홍삼 제조시 내공의 발생은 제조공정에서 나타나는 경우가 많으며, 내백의 경우는 홍삼으로 가공되면서 발생하는 경우가 있고, 인삼이 성장될 때 부분적인 영양상태의 불충분이나 기후 등에 따른 영향을 받을 수 있기 때문에 앞으로 이에 대한 많은 연구가 이루어져야할 것으로 판단된다.태에도 불구하고 [-wh]의미의 겹의문사는 병렬적 관계의 합성어가 아니라 내부구조를 지니지 않은 단순한 단어(minimal $X^{0}$ elements)로 가정한다. 즉, [+wh] 의미의 겹의문사는 동일한 구성요 소를 지닌 병렬적 합성어([$[W1]_{XO-}$ $[W1]_{XO}$ ]

This research, with the participants of the female elderly using a home-visit bath among long-term care services, made an in-depth analysis of what they experience while getting a home-visit bath. We conducted in-depth interviews with 8 elderly people. According to the result, the female elderly experienced the absence of a caregiver, difficulty in carrying out daily life due to physical diseases, getting what they need by themselves, getting comfortable in body and mind, accepting their given situation though feeling shame at getting a bath, and expressing their desires. In addition, they had a close relationship with a care helper. On the basis of the results, a systematic training system which could intensify the professionalism of care helpers was suggested. For the enhancement of the elderly's emotional stability in a long-term care, an integrated case management system was also suggested, which supports the family by organizing an integrated network by region between a long-term care service, home-visit care service, welfare center, and the National Health Insurance Corporation.

This study was conducted to evaluate the productivity of whole crop silage wheat utilizing the paddy fields during a couple of years from 2019 to 2021 in Suwon, Korea. This investigation was used the two maturity types of wheat cultivar 'Cheongwoo' (early) and 'Taeu' (late). The heading date of 2^nd year (Oct. 2020 to May. 2021) cultivation was delayed about 11 to 13 days by more than 1^st year (Oct. 2019 to May. 2020). The growth characteristics were shown that the plant height was increased in 2^nd cultivation, while the number of culms and the panicle part ratio were decreased. Moreover, the nutritive value of 'Cheongwoo' and 'Taeu' were also decreased in 2^nd cultivation. These changes have thought to a difference of the precipitation by cultivation years. Because, the precipitation during the period from the end of winter dormancy to the harvesting stage in 2^nd (337 mm) cultivation was more about twice than 1st (169.3 mm) cultivation. However, the dry matter yield of 'Cheongwoo' was not shown a statistical difference by cultivation years, while 'Taeu' was shown to decrease tendency. The total dry matter yield regardless of the cultivation years were higher in 'Cheongwoo' than 'Taeu', and especially 'Cheongwoo' was more 3 tons per hectare (15.3 t/ha) than 'Taeu' (12.6 t/ha) at 2^nd cultivation (p<0.01). The trend of dry weight in 'Cheongwoo', early mature type, showed a relatively high ratio of dry matter (p<0.05) was considered that due to a high panicle ratio by a fast heading and an adequate weight of panicles by a sufficient maturing. In conclusion, selecting the early maturity cultivars could achieve a higher and more stable total dry matter yield considering the cropping system in the central region. Furthermore, it also has the advantage of being able to double-cropping system with forage rice, which has considered the maximum whole-crop forage production year-round. These results suggest that the 'Cheongwoo' be optimum cultivar to produce the year-round forage on paddy fields in the central region.

Current tourism is quickly transforming into experiential and insightful tourism from simple sightseeing tourism. Due to the experiential tourism trend, cultural interpretation of cultural tourism interpreter has a significant meaning in experiential tourism for tourist. This research was conducted on tourists visiting a representative palace of Korea, Gyeongbokgung, regarding how contents and communication skill of cultural tourism interpretation influence revisit intention of the tourists. As a result, value and interest of interpretation contents influence positive impact on tourist satisfaction. Second, progress and attitude of interpretation give positive influence on tourist satisfaction but not effective on communication with audience. Third, we found that tourist satisfaction influences positively on revisit intention. As the research result shows, both context and communication skill of interpretation are very important factors in cultural tourism interpretation. Therefore, the research emphasizes on government's suport on systematic management, treatment and position of cultural tourism interpreter retraining program.

This essay explores the ways in which the philosophical concept of "original form" is expressed in relevant laws and regulations, the legal character of respective regulations, the way in which each regulation is applied in practice for heritage management, and the factors required for this concept to serve as a legally binding fundamental principle. The current laws and regulations on heritage maintain a consistent requirement for preserving the original form of heritage, both for the general public and for heritage professionals. However, the principle of preserving original form is expressed as a declaration or imperative without substantive definitions. Consequently, heritage administrators simply follow administrative procedures for heritage conservation, management, and promotion while failing to specify the meaning of "original form." For the practical application of the principle of preserving original form to overall heritage conservation activities as an actual legal principle, further provisions should be added for the purpose of clarifying the principle, with consideration given to the observation of fundamental principles for legal provisions, such as the principles of clarity, equality, and proportion. The principle of preserving original form still functions as the most necessary principle for heritage conservation and therefore should be reestablished as a refined and rational regulatory system.
