고로쇠수액의 채취시기별 이화학적 특성 및 영양성분을 분석하였다. 고로쇠수액의 갈변도 및 탁도는 채취시기가 늦어질수록 증가하는 경향을 보였으며, pH 및 총산도는 큰 차이가 없었다. 유기산은 citric acid 및 malic acid가 검출되었으며, citric acid는 채취시기가 늦어질수록 감소하는 경향을 보였고 malic acid는 증가하였다. 유리당은 sucrose와 fructose 및 glucose가 검출되었으며, sucrose는 채취시기가 늦어질수록 감소한 반면, fructose는 증가하였고 glucose는 채취시기 후반기에만 검출되었다. 조단백질과 조회분은 채취초중반기에는 변화가 없었으나, 후반기에 많은 증가를 보였다. 무기성분은 Ca, Cu, Fe, K, Mg 및 Mn 등이 검출되었으며, K, Mg 및 Fe는 채취기시가 늦어질수록 증가하였다. 이상의 결과로부터 채취시기 후반기에 채취되는 고로쇠수액은 탁도의 증가로 인하여 음용하기 어렵지만, 조단백질, 유기산, 무기성분 등의 증가로 영양적으로 우수할 것으로 판단되므로 적절한 가공방법을 이용하여 탁도를 제어한다면 이용률 향상에 도움이 될 것으로 판단된다.

A study was conducted to determine the effect of prostaglandin $F_2$ alpha ($PGF_2$ alpha) on the reaction time and seminal characteristics of buffalo bulls. Semen was collected from three Murrah bulls in three periods: pre-treatment, treatment and post-treatment. During the treatment period each bull was administered 2 ml $PGF_2$ alpha (Synchrocept, Fenprostalene) im, 1 hour prior to semen collection. In the post-treatment, semen was collected 7 days after the last injection of $PGF_2$. Semen samples were evaluated immediately after collection. Pre-collection injection of $PGF_2$ alpha has no significant effect on reaction time, semen volume, percentage motility, sperm concentration and total number of sperms per ejaculate. Fluctuations in semen color and consistency were observed. There is a significant (p<0.05) increase in the mean percentage of normal spermatozoa during the treatment and post treatment periods. Likewise, administration of PG results into a significant (p<0.05) rise on the average percentage of live sperms but this effect was not manifested in the post-treatment period. Improvement in mass activity was observed during the treatment and post-treatment periods.

Effects of various preservation periods and subcultures on fruiting body formation of Cordyceps militaris were investigated using EFCC C-10995 single ascospore strains. Fruiting body formation by original strains was profuse when preserved at $4^{\circ}C$ for $5{\sim}6$ months. Fruiting from subcultures was stable till second to sixth subcultures, after which it decreased sharply. The more the colony color of subcultures changed, the less the fruiting bodies formed. Liquid inoculum preparation of single ascospore strains in the same or separate broths did not affect fruiting body formation. Similarly, two strains C-10995-3 and C-10995-6 in different numbers during liquid inoculum preparation produced similar fruiting bodies.

This article reports an attempt to perform a similarity analysis on a collection of 25 culinary manuscripts in Chosun periods using a set of quantitative text analysis methods. Historical culinary texts are valuable resources for linguistic, historic, and cultural studies. We consider the similarity of two texts as the distributional similarities of the functional components of the texts. In the case of culinary texts, text elements such as food names, cooking methods, and ingredients are regarded as functional components. We derive the similarity information from the distributional characteristics of the two key functional components, cooking methods and ingredients. The results are also quantified and visualized to achieve a better understanding of the properties of the individual texts and the collection of the texts as a whole.

Objective: The hypothesis was that apparent ileal digestibility (AID), basal endogenous losses, and standardized ileal digestibility (SID) of amino acids (AA) are not affected by adding acid to collection containers or bags used to collect ileal digesta from pigs. Methods: Twenty-four growing barrows (initial body weight: 77.8±4.5 kg) that were fitted with a T-cannula in the distal ileum were fed diets for three 7-d periods. An N-free diet and 3 diets containing corn, soybean meal, or wheat middlings as the sole source of AA were used. Within each period, each of the 4 diets were fed to 6 pigs. Among the 6 pigs, digesta from 3 pigs were collected in bags containing no HCl, whereas 40 mL of 3 N HCl was included in the bags used to collect digesta from the remaining 3 pigs. Every other bag collected from each pig was emptied into a container without adding HCl, whereas the remaining bags were added to a container along with 40 mL of 3 N HCl for each bag. All digesta were stored at -20℃ immediately after collection. Data were analyzed using a model that included feed ingredient, HCl in bags, HCl in containers, and all 2-way and 3-way interactions as fixed effects. No 3-way interactions were significant, and data were, therefore, reanalyzed independently for each diet as a 2×2 factorial. Results: There were no interactions between adding HCl to collection bags and to containers, and no effects of adding HCl to collection bags or containers for AID, basal endogenous losses, or SID of most AA were observed. Conclusion: It is not necessary to add acid to digesta collection bags or collection containers if ileal digesta are stored at -20℃ immediately after collection.

기록관에서 수집정책은 수집을 위한 지침서로서의 역할 뿐 아니라 기록관의 업무계획 수립과 업무절차 실행 방안을 개발하는데 기초가 된다. 또한, 수집정책은 법률이나 규정에서 모두 다룰 수 없는 구체적이고, 세부적인 내용을 수립할 수 있으므로 기록물 수집 시에 체계적이고 전략적인 접근을 가능하게 해준다. 우리나라와 동일한 대통령제 국가인 미국은 개별 대통령기록관마다 수립된 시기는 상이하지만 이미 반세기 전부터 수집정책을 수립하여 기록물 수집을 위한 근거자료로서 활용하고 있다. 이와는 반대로 국내 대통령기록관은 아직까지 수집정책을 수립하지 않고 있으며, '수집규정' 및 '수집계획'에 기반하여 수집이 이루어지고 있는 실정이다. 미국 대통령기록관의 수집정책과 국내 대통령기록관의 '수집규정' 및 '수집계획'을 비교하여 살펴보면, 미국의 경우 대통령의 특성을 반영하여 재임기간 생산하여 이관 받은 기록물 이외에도 대통령과 관련한 인물 사건 지역뿐 아니라 개인적 관심사를 반영한 개인기록물에 대해서도 적극적으로 수집하고 있으며, 그 범위 및 절차에 이르기까지 상세하게 기술하고 있다. 반면, 국내 대통령기록관의 '수집규정'과 '수집계획'은 개별 대통령에 따른 기록물의 특성을 충분히 반영하지 않은 일반적이고 모호한 수준에 그치고 있어, 일관되고 전문화되어야 할 수집 업무의 연속성을 유지하기 어려워 보인다. 이에 본 연구에서는 미국 개별 대통령기록관의 수집정책 사례분석을 통하여, 시사점을 도출하고, 국내 대통령기록관의 개별 대통령에 따른 수집정책 수립방안을 제안하는 데 그 목적을 두었다.

Field measurements of the wind-induced response of two residential reinforced concrete buildings, among the tallest in the world, have been performed during two typhoons. Natural periods and damping values have been determined and compared with other field measurements and empirical predictors. Suitable and common empirical predictors of natural period and structural damping have been obtained that describe the trend of tall, reinforced concrete buildings whose structural vibrations have been measured in the collection of studies in Hong Kong compiled by the authors. This data is especially important as the amount of information known about the dynamic parameters of buildings of these heights is limited. Effects of the variation of the natural period and damping values on the alongwind response of a tall building for serviceability-level wind conditions have been profiled using the gust response factor approach. When using this approach on these two buildings, the often overestimated natural periods and structural damping values suggested by empirical predictors tended to offset each other. Gust response factors calculated using the natural periods and structural damping values measured in the field were smaller than if calculated using design-stage values.

This paper proposes a flooding safety system (FSS) and its operation strategy that can provide long-term safety and effective maintenance for modules of small modular reactor (SMR) and metal containment maintained at dried environment during normal operation. During hypothesized accidents, the FSS re-collects the evaporated steam into the common pool by the condenser installed above the common water pool and provides an emergency coolant for the cavities and auxiliary pools. This study suggested that the condensate re-collection strategy using the FSS can effectively delay the depletion of available water in response to the accidents. Without recollection, the achievable grace periods ranged from 44 to 1507 days for six-module and one-module accidents, respectively. However, with a full re-collection (ratio = 1.0), the time to total depletion of emergency coolant was estimated indefinite. Even with a partial re-collection ratio of 0.3, a grace period of 83.5 days could be ensured for a six-module transient. This study reported the effectiveness of condensate re-collection and the FSS as an innovative safety management strategy and system. Employing a condensate re-collection strategy with a high re-collection ratio can enhance the long-term safety and effective convenience of SMR operations and maintenance.

Due to the rapid growth of publications, librarians have been facing the problems caused by the shortage of stack as well as the quality deterioration of library collections. This naturally disappointed the user communities and the present library activities are weak and inadequate. It seems to the author that one of the desirable actions in remedying this problems is to weed library collections properly and regulraly. The purpose of this study is to establish weeding criteria in library collections, particulary in the fields of polictical science, economics and law In order to establish weeding criteria, shelf-time period which is the length of time that a book remains on the shelf between the last two users of a volume, was measured by examining the book cards or date-due slips of circulating books and collections which remained in the stack. The results of this study are as follows: (1) In the fields of political science economics and law, the shelf-time periods of general materials in Korean for circulation was measured. (2) This study shows shelf-time periods that vary in different subject fields. (3) Combining the shelf-time periods of books in active circulation and the total collection including books which have never been circulated, the size of library holdings which may satisfy a certain percentage of the current circulation can be estimated.

The growing demand for the real time traffic information is bringing about the category and number of traffic collection mechanism in the era of ITS. There are, however, two problems in making data into information using various traffic data. First, the information making process of making data into the representative information, for each traffic collection mechanism, for the specified analysis periods is required. Second, the integration process of fusing each representative information into "the information" for each link out of each source is also required. That is, both data reduction and/or data to information process and information fusion are required. This article is focusing on the development of information fusing algorithm based on voting technique, fuzzy regression, and, Bayesian pooling technique for estimating the dynamic link travel time of networks. The proposed algorithm has been validated using the field experiment data out of GPS probes and detectors over the roadways and the estimated link travel time from the algorithm is proved to be more useful than the mere arithmetic mean from each traffic source.
