A study is reported which investigated the additive nature of digestible energy (DE) from dietary nutrients and to estimate the relative energy values of different energy-yielding nutrients in practical trout diets. A growth study was conducted over 12 weeks with 6 diets. Rainbow trout (Oncorhynchus mykiss) were fed diets once a day ad libitum. Digestible energy values determined and calculated had direct relationship indicating additive nature of such values for feed ingredients. Overall growth performance was best in a diet containing 33% digestible protein (DP) with a DP/DE ratio of 18.6. A reduction in digestible protein level with the same DP/DE rat io led to a significant decrease in growth and feed efficiency. The increase of 7% of lipid with concomitant decrease in protein resulted in the relative gain of 130% in growth and nutrient retention, suggesting that 1 g of lipid is equal to about 1.3 g of proteins in terms of net energetic value. Replacement of 10% of dietary lipid by carbohydrates led to a slight decrease in energy retention efficiency but to a great increase in lipid retention efficiency (130%) showing that dietary carbohydrates led to increased lipogenesis.

The effect of cardiopulmonary bypass procedures on the blood components were studied through the measurements of several serum enzymes, SGOT, SGPT, CPK and LDH with its isozymes in the patients who had surgery for their heart diseases. They wre 85 patients: 40 Males and 45 Females. Their ages ranged widely between one and fifty-six. They were divided into 5 groups: Group I.patent ductus arteriosus without extracorporeal circulation, Group II-atrial septal defect, Group III-ventricular septal defect, Group IV-tetralogy of Fallot, and Group V-valve replacement. Generally serum enzymes revealed the increased values after surgery and the tendency returning toward preoperative levels. With the high total serum LDH levels seen uniformly after operation which persisted long in patients with replaced valves, the changes of LDH-isozymes were further analyzed. The isozymes, especially LDI and LDs increased their activities postoperatively, and the other fractions varied little. And $LD_1$/$LD_2$ ratios also showed similar rises and falls while the elevated values lasted longer in the patients with cardiac valve replacement. The significant values of LDH-isozymes in predicting the hemolysis occuring after extracorporeal circulation and in following the patients whose valves were replaced have been further discussed with the special stress placed on the $LD_1$/$LD_2$ratios.

이 논문에서는 최근 강화된 내진규정에 의하여 현장에서 시공에 어려움을 겪고 있는 특수전단벽의 배근상세를 완화할 목적으로 제안된 경계요소 횡보강상세에 대하여 횡보강근의 형태와 배근간격에 따른 실험결과를 제시하고 있다. 실험결과, 제안된 횡보강 상세를 채용한 실험체의 균열 및 파괴양상은 폐쇄형 후프를 사용한 실험체와 유사한 경향을 나타내었으며, 최대강도도 예상값을 모두 상회하는 것으로 나타났다. 또한, 에너지 소산능력을 비교한 결과, 완화된 배근상세를 따르는 실험체(SSWR2)의 경우 기존 설계기준의 특수전단벽 실험체(SSW2)와 유사한 내진성능을 가지고 있는 것으로 나타났으며, 설계기준에서 제시하고 있는 1.5% 수준의 변형각 조건을 충분히 만족하고 있어 구조물의 주요 횡력저항 요소로서 사용될 수 있을 것으로 판단된다.

Purposes: This research is conducted to identify main features and trends of mission, vision and core values in Korean tertiary general hospitals by using text-mining. Methodology: For the study, 45 mission, 112 vision and 190 core values are collected from 45 tertiary general hospitals' homepages in 2022 and use word frequency analysis and Leyword co-occurrence analysis. Findings: In the tertiary general hospitals' mission, there are high frequency words such as 'health', 'humanity', 'medical treatment', 'education', 'research', 'happiness', 'love', 'best', 'spirit', and mission mainly includes the content of contributing humanity's health and happiness with these words. In case of vision, high frequency words are 'hospital', 'medical treatment', 'research', 'lead', 'trust', 'centered', 'patient', 'best', 'future'. By using these words in vision, it represents the definition and characteristics of vision such as ideal organizations in the future, goals and targets. As a result of the Leyword co-occurrence analysis, vision includes the content of 'high-tech medical treatment', 'special care for patients', 'leading education and research', 'the highest trust with customer', 'creative talents training'. -astly, the high frequency word-pairs in core values are 'social distribution', 'innovation pursuit', 'cooperation and harmony', and it defines standards of behavior for organizations. Practical Implication: To correct the problems of vision, mission and core values from findings, firstly, it needs for Korean tertiary general hospitals to use the words that can explain organization's identity and differentiate others in their mission. Secondly, considering strengthening the role of hospitals in their community and the importance of members in organizations, it is necessary to establish vision with considering community and members to activate vision effectively. Thirdly, because there are no specific guidelines of establishing mission, vision and core values for healthcare organizations, this research concepts and results could be utilized when other organizations establish mission, vision and core values.

This paper describes a parameter extraction method for HBT(Heterojunction Bipolar Transistor) equivalent circuit model without measurements of special test structures or numerical optimizations. Instead, all equivalent circuit parameters are calculated analytically from small-signal S-parameters measured under different bias conditions. These values being extracted from the cutoff mode can be used to extract intrinsic parameters at the active mode. This method yields a deviation of about 1.3 % between the measured and modeled S-parameters.

We generate ring class fields of imaginary quadratic fields in terms of the special values of certain eta-quotients, which are related to the relative norms of Siegel-Ramachandra invariants. These give us minimal polynomials with relatively small coefficients from which we are able to solve certain quadratic Diophantine equations concerning non-convenient numbers.

A geometric construction of an exact algebraic formula for graded partition functions, of which a special one is the classical unrestricted partition function p(n), from a diophantine point of view is presented. Moreover, the involved process allows us to compute the value of a graded partition function in an inductive manner with a geometrically built-in self-error-checking ability at each step for correctness of the computed values of the partition function under consideration.

In this Paper we consider non-deterministic finite Rabin-Scott's automata. We define special abstract objects, being pairs of values of states-marking functions. On the basis of these objects as the states of automaton, we define its edges; the obtained structure is considered also as a non-deterministic automaton. We prove, that any edge of any non-deterministic automaton defining the given regular language can be obtained by such techniques. Such structure can be used for solving various problems in the frames of finite automata theory.

We propose a class of hierarchical Bayes estimators of the error variance under the relative squared error loss in balanced fixed-effects two-way analysis of variance models. Also we provide analytic expressions for the risk improvement of the hierarchical Bayes estimators over multiples of the error sum of squares. Using these expressions we identify a subclass of the hierarchical Bayes estimators each member of which dominates the best multiple of the error sum of squares which is known to be minimax. Numerical values of the percentage risk improvement are given in some special cases.

This paper is concerned with the design of an appropriate sampling plan or stopping rule and the construction of estimate for the estimation of process or lot fraction defective. Various sampling plans which are well known or have potential applications are unified into a generalized sampling plan. Under this sampling plan sufficient statistic, probability distribution, moment, and minimum variance unbiased estimate are obtained. Results for various sampling plans can be derived as special cases. Then, under given parameter values, the relative efficiencies of the various sampling plans are compared with respect to expected sample sizes and variances of estimates.
