The case study describes kindergarten children's reading stances and responses with relation to those of their mothers'. Rosenbaltt's theory (1978) of aesthetic and efferent stances in used to characterize the relationship between the reader and the text. mother's reading stances are examined by observing each case study child's reading experience with his/her mother at home. In most cases differences in some children's preferred stances seemed to reflect differences in their mothers' stances. As a result, children took a different type of stance from the teacher's efferent stance and were perceived by the teacher to be slower with regard to literacy development, even though they had formed their own reading worlds. Interestingly enough, children with an aesthetic reading stance were welcomed among their peers during free play time. In contrast, children who took a stance congruent with the teacher's efferent stnace were perceived by the teacher to be on the right track with regard to literacy development, although their reading worlds seened to be limited. Interestingly, the children with efferent reading stances were not engaged in collaborative meaning negotiation processes with peers. The case study children with mothers who did not take an extreme type of stance, I.e., neither a very efferent nor a very aesthetic stance, seemed to choose a type of stance depending on a context.

No phosphatidylcholine (PC) was detected in the membrane of Rhodobacter sphaeroides pmtA mutant (PmtAl) lacking phosphatidylethanolamine (PE) N-methyltransferase, whereas PE in the mutant was increased up to the mole % comparable to the combined level of PE and PC of wild type. Neither the fatty acid composition nor the fluidity of membrane was altered by pmtA mutation. Consistently, aerobic and photoheterotrophic growth of PmtAl were not different from wild type. However, PmtAl showed an extended lag phase (15 h) after the growth transition from aerobic to photoheterotrophic conditions, indicating the PC requirement for the efficient formation of intracytoplasmic membrane (ICM). Interestingly, the B800-850 complex of PmtAl was decreased more than twofold in comparison with wild type, whereas the level of the B875 complex comprising the fixed photosynthetic unit was not changed. Since puc expression is not affected by pmtA mutation, PC appears to be required for the proper formation of the B800-850 complex in the ICM of R. sphaeroides.

This paper aims to analyze whether company characteristics are potential determinants of human resource accounting (HRA) disclosure practices by Vietnamese listed companies. It examines the human resource disclosure level of 204 companies by content analysis of these companies' annual reports. The study has relied on a multiple linear regression to test the association between a number of corporate attributes and the extent of human resource disclosure in companies' annual reports. The extent of human resource disclosure was measured using unweighted human resource disclosure index. The explanatory variables considered in this study were firm size, firm age, profitability, leverage, industry profile, and auditor type. The results revealed that the most influential variable for explaining firms' variation in human resource disclosure is firm size followed by firm age and profitability. Thus, it can be concluded that firm size, firm age and profitability are major predictors that may affect the variety of HRA disclosure practices on firms listed in the Vietnam Stock Exchange. However, neither industry profile nor auditor type seems to explain differences in human resource disclosure practices between Vietnamese listed firms, indicating that company's industry profile and auditor type are not a matter for the company to disclose HRA information.

Objectives: Type 2 diabetes mellitus is a metabolic disease characterized by insulin resistance and high blood glucose level from progressive insulin secretory defect. The rhizome of Atractylodes japonica Koidz. (AJ) has been used for treatment of retention of water in oriental medicine. The aim of this study is to examine the effects of AJ on type 2 diabetes rats. Methods: Type 2 diabetes was induced by 60% high fat diet and low dose streptozotocin. Rats were divided into 4 groups (n = 6); Nor (normal control group), Con (diabetic group treated with vehicle), Met (diabetic group treated with 200 mg/kg metformin) and AJ (diabetic group treated with 100 mg/kg AJ). The body weights and food intakes were measured during the treatment period. After 4 weeks treatment, blood glucose level, HOMA-IR, and protein expressions of IRS-1, p-IRS-1, PPAR-${\gamma}$, and GLUT4 were measured, and histopathological examination of beta cell was performed. Results: Compared with the control group, blood glucose level and HOMA-IR were reduced in rats treated with AJ. Impaired beta cells in pancreas of rats were recovered and phosphorylation of IRS-1 was increased in rats treated with AJ. And also, protein expressions of PPAR-${\gamma}$ and GLUT4 were increased by treatment of AJ. Conclusions: The results suggest that Atractylodes japonica Koidz. may have anti-diabetic effect on type 2 diabetic rats through regulation of blood glucose level and insulin resistance. Therefore Atractylodes japonica Koidz. may have positive effects on patients with type 2 diabetes.

The type II secretion system (T2SS), which transports selected periplasmic proteins across the outer membrane, has rarely been studied in nonpathogens or in organisms classified as Betaproteobacteria. Therefore, we studied Cupriavidus metallidurans (Cme), a facultative chemilithoautotroph. Gel analysis of extracellular proteins revealed no remarkable differences between the wild type and the T2SS mutants. However, enzyme assays revealed that native extracellular alkaline phosphatase is a T2SS substrate, because activity was 10-fold greater for the wild type than a T2SS mutant. In Cme engineered to produce three Ralstonia solanacearum (Rso) exoenzymes, at least 95% of their total activities were extracellular, but unexpectedly high percentages of these exoenzymes remained extracellular in T2SS mutants cultured in rich broth. These conditions appear to permit an alternative secretion process, because neither cell lysis nor periplasmic leakage was observed when Cme produced a Pectobacterium carotovorum exoenzyme, and wild-type Cme cultured in minimal medium secreted 98% of Rso polygalacturonase, but 92% of this exoenzyme remained intracellular in T2SS mutants. We concluded that Cme has a functional T2SS despite lacking any abundant native T2SS substrates. The efficient secretion of three foreign exoenzymes by Cme is remarkable, but so too is the indication of an alternative secretion process in rich culture conditions. When not transiting the T2SS, we suggest that Rso exoenzymes are probably selectively packaged into outer membrane vesicles. Phylogenetic analysis of T2SS proteins supports the existence of at least three T2SS subfamilies, and we propose that Cme, as a representative of the Betaproteobacteria, could become a new useful model system for studying T2SS substrate specificity.

This thesis is focused on kinematical and kinematical analysis of each types(Type #1 : use both swing of arm and reaction of knee, Type #2 : Use only swing of arm, not reaction of knee, type #3 : Neither use of swing of arm nor reaction of knee) of vertical jumps according to gender of High School Students. The subjects of this study is High School Student's male and female, 5 each, for analyzation of actions 3D image analyzing and GRF machines were used. To identify the differences of analyzed variables, an independent T-test on gender, an One-way ANOVA on types were used. Summery of the results are stated below. first of all, female students showed differences on Hip Joint angle and Joint Velocity from male students on Kimentic Variable. So training on hip joint force of flection and extension of female students is needed. Both male and female students showed relatively bigger result of arm's Angular Momentum than thigh's Angular Momentum on Type #1. This is regarded of faster Joint Velocity of Arm. Bigger result of female students of arm's contribution on Type #1 than male students can be said as Female student's weaker hip joint's angular muscle force than male student's, so the dependency of arm is heavier than male students. In Kinetic variable, GRF showed bigger result on male students than female students. So female students need to enhance joint's torque to increase GRF than male students. On vertical Impulse, high numeric data of last two reaction of tiptoe of vertical GRF and antero-posterior GRF helped increasing impulse by extending action time of force.

Appropriation of partial substitution of concentrate mixture by urea-molasses-mineral block (UMMB) lick supplements for 20 lactating crossbred cows in 2nd and 3nd lactation was studied. Animals fed on wheat straw ad lib. and Berseem (Trifolium alaxandrium) fodder @ 1.5 kg/d on dry matter basis. Animals of control group were given concentrate supplement, while in treatment groups 10% of the concentrate requirement was substituted with 3 different types of UMMB lick type A ($T_1$), type B ($T_2$) and type C ($T_3$). CP content of the ration was 15%. Total dry matter intake (DMI) was about 1.0 kg/kg of fat corrected milk (FCM) yield and was not significantly different between control and treatment groups. Digestibility of neither proximate principles nor cell wall constituents were deviated on UMMB licks partial supplementation. FCM yield was increased by 140, 410 and 460 g/d, in $T_1$, $T_2$ and $T_3$, respectively, in comparison to control group but differences were statistically invalid. Though fat per cent was reduced, fat yields were remain constant among treatments. Milk composition was unaltered except significant difference (p < 0.01) in non-protein nitrogen (NPN) content. Gross-N and digestible-N conversion was significantly higher (p < 0.01) with $T_1$, $T_2$ and $T_3$ than control group. Energy utilization efficiency for milk production was only 36%. Result demonstrated that UMMB licks could be partial supplemented up to 10% of the concentrate requirement of crossbred cows yielding on an average 14kg/d without any adverse effect on feed intake, nutrient utilization and mild production. Comparatively, UMMB lick type B and C was proved better than type A and also economically viable.

The system and symbolizing ideologic meanings of the metallic Kwon in period of the Three-Kingdoms were comsidered by comparing to their cultural path and structal styles throughout the tree and the deer worship ideology. The results of this study are as followings; Firstly, the beginning of the Korean, mostly northern style was originated from metal tools of the Bronze age in BC 6c-7c. The maJ;lufature of the metallic adornment brought the pr-evailing use of metallic objects of craftwork after the supply of ironmongery. Secondly, the cultmal characteristics of the metallic Kwan in the kor-ean Peninsula were influenced f-rom the northern chinese tribes, Momg Go, Hung No, and Sien-pi who were transmitted from the scythian of the southern Russia having a prefenence for gold. Thir-dly, the metallic Kwon of the Kogmgo and the Baekje era was ideologically based on the ar-t of Buddism of the pattern of blazing flame, the carved pattern of flower- of herb, and the honey. sukle which were tramsmitted to china thr-ough the silk noad. Fourthly, the metallic K wam of the silla era consisted of the tree and the antler types in closely nelated to the tree and the deer ideology which were based on the background of shamanism. It should be raid that the metallic Kwan of the silla esa are connected to the type of nor-them ancient K wan. Lasthy, the metallic Kwan-Mo of the Kaja esa was mosthy original type of flower of herb even if kome of these ar-e similiar to the tree adornment type of silla. This type of flower of herb in based on the scythian type with a statue im silveer founded at Alexandnopol in the southern russia.

The purposes of the study were to introduce a new approach in overcoming career problems of adolescents with multicultural backgrounds, and to explore public views on their careers. Using the Q-methodology, the types of perception toward multicultural adolescents' careers and their features from diverse views were drawn, Data from 35 participants and 34 statements were analyzed by using the QUANL-PC program. The identified perception types were classified as four types: neutral perception type, economic hardship perception type, lack of career training perception type, and lack of professional support perception type. The results found that views toward career problem of adolescents with multicultural backgrounds are neither positive nor negative, and their perceptions were more varied and specific beyond the dichotomy. Therefore, to promote the careers development of adolescents with multicultural backgrounds, more individualized career supporting strategy should be provided based on the applicable perception types.

Travel YouTubers who cross the boundary between tradition and novelty communicate by sharing their activities with others through SNS-based media. Media content should not only satisfy individuals, nor should it be too purpose-oriented. YouTube channels should be operated so that users can easily access content naturally, and more diverse methods can be pursued based on usage patterns and satisfaction theory. This study is about the type of perception of Generation Z on travel YouTube titles. As a result of conducting QUANL program analysis on 34 Q samples and 28 P samples from the Q methodological perspective, a total of three types were found. For types with unique characteristics, the first type was named "attention of keywords that draw imagination," the second type was "preferred to stories that stimulate curiosity," and the third type was "image satisfaction reflecting expectations." In addition, considering the characteristics of each type found, the scalability and strategic plan of the activities that Generation Z travel YouTubers want to unfold were presented.
