This study investigates the factors influencing service outcomes of group homes and residential care centers, as well as the factors causing any differences between the two service outcomes. 119 and 137 5-6th graders were selected from group homes and residential care centers respectively, using the cluster sampling method. Multiple regression and Blinder-Oaxaca decomposition were used in this study. The results revealed that 'stigma', 'school adjustment', and 'social support' were significant factors influencing service outcomes among children in group homes, while 'stigma', 'primary caregivers' attitude', and 'peer relations' were identified as significant factors among children in residential care centers. The study also found that the mean service outcome score for group homes was higher than that of residential care centers. The 74 percent of this difference in the mean scores was due to the difference in children' characteristics of the two out-of-home care service types. The remaining 26 percent of this difference was due to unobserved characteristics. Finally, the implications of this study in child welfare practices were also discussed.

The following are what this auther concluded in his recent research of bamboo cultivation. 1. The bamboo logging should be prohibited during the months of July and August, for during that season the growth of the terrestrial stem is most vigorous and active. 2. The growth of terrestrial stem of the phyllotachys pubescens is not likely to be affected the soil texture on which it grows and it is sappling sprout out well enough in any kind of soil, but it was found out that it grows in the best condition on the sand-clay soil and in next best condition on the clay-soil. 3. The bamboo blossoming takes always most of the nutritions needed for the growth of the terrestrial stem and causes to decay 90 percent of the next year buds which await in the terrestrial stem to sprout as the sappling. The remaining 10 percent of the buds is to be the "re-incarnated bamboos" 4. The terrestrial thin roots of blossoming bamboo are negative in their growth, too weak in absorbing the nutrition. The above stated facts show, to be brief, that growth of bamboo depends largely upon that of the terrestrial stem.

The core purpose of the paper is to explore perceptual displays of rural India towards the role and impact of ICT in transforming the lives through education and telecommunications. After meticulous review of pertinent literature on ICT, and its policy framework, the researcher administers both quantitative and qualitative field data collected from the villages of Andhra Pradesh, Karnataka, Kerala, and Tamil Nadu with a sample of 250 from each state. More than 90 percent of respondents from the four southern states in India clearly thought that the role and impact of ICT is very momentous. Predominantly, cent percent respondents from Kerala evinced that ICT is the major reason for achieving the tag of "100% Literacy State". And also in the remaining three states viz., Andhra Pradesh, Karnataka, and Tamil Nadu, the literacy rate has crossed mind-boggling figures only because of ICT's reinforcement. Even in the arena of telecommunications, these four states average telecom density is more than the country's average. The paper concentrated only on how ICT function empirically to build human capacity in rural south-India through the sectors of only education and telecom. This study is first of its kind and precious to all stakeholders of the ICT sector like educational institutional, telecom firms, customers, employees, and governments, etc.

The present study has been undertaken to analyze scan manifestations in obstructive jaundice. Scan changes were cprrelated with the duration of jaundice. In addition, clearance rates of trace dose of colloidal radiogold were assessed in each case. The materials were consisted of 19 cases with surgically and/or histopathlogically verified obstructive jaundice from various causes including common duct stone, empyema of the gall bladder and carcinoma of the pancreas head etc. Blood clearance rates of colloidal $^{198}Au$ were determined after the injection of 8 uCi by simple geometrical drawing of recorded strip charts. Scan was performed following additional injection of the same radiogold. In 16 out of 19 cases, the scan revealed rather typical "arborifrom" mottlings around the porta hepatis. The intensity and appearance of such mottlings on the scan was related with the duration of jaundice and level of serum bilirubin and alkaline phosphatase. The blood clearance rates remained to be within normal range in 74 percent of the patients. In the remaining 26 percent, clearance rates ranged between 4.1 and 6 minutes. It is concluded that the association of "arboriform" mottlings and normal or mildly delayed clearance rates in the patients with jaundice is characteristic of obstructive changes in the biliary system.

Objectives: This study measures the level of cognition of employee's patient safety culture and evaluates the current level through comparing the results to external levels. Ultimately it is performed to construct a strategic improvement plan through the basic database for patient's safety culture. Methods: A questionnaire survey of self reporting type was carried out using structured questionnaire of the patient's safety culture for employees currently employed in a hospital. Total responders was 1,129 and a response rate was 54.6%. The survey results were calculated with a percent positive response, and the current level was evaluated by comparing with the survey results of a hospital (2009 and 2014) and the survey result of The Agency for Healthcare Research and Quality(2014). Results: Sub-dimension of high percent positive response for each area were 'teamwork within hospital units' (80%), 'feedback & communication about error' (73%) and 'supervisor/manager expectations & actions promoting safety' (67%). Meanwhile, 'teamwork across hospital units' (31%), 'hospital management support for patient safety' (29%), 'staffing' (27%) and 'non-punitive response to error' (17%) were relatively low percent positive response. Compared to the survey results of AHRQ (2014) for each area, 'teamwork within hospital units' (80%), 'feedback & communication about error' (73%), 'frequency of event reporting' (66%) were at the top 50% percentile level and the remaining sub-dimensions showed a very low level in the lower 10% percentile area. Conclusion: In order to establish a system for patient safety culture within the hospital and evaluate the effect on this, it is necessary to periodically evaluate the patient's safety culture and establish regulations on hospital safety culture to comply with this.

Aluminum dross should be recycled in consideration of characteristics of the dross and its reutilization after processing. In this study, aluminum dross generated in the domestic secondary aluminum industry was processed to use it as raw material for producing aluminum hydroxide. Sample dross was classified according to its size. The dross smaller than 1mm was leached with sodium hydroxide solution to extract the remaining aluminum from the dross into the solution, and then aluminum hydroxide precipitate was recovered from the leach liquor. Purity of the obtained aluminum hydroxide was above 98 percent, and particle size of the sample was in range of 3-39${\mu}{\textrm}{m}$. From the result, it was suggested that this process could be applicable to recycling of aluminum dross.

Perhaps, one of the typical emerging markets drawing tremendous attention from not only business professionals but also policy-makers would be the mobile Internet services. In recent years many research institutes reported their predictions on the growth of the mobile Internet services market, announcing that the market would show explosive growth and replace the wired Internet service market rapidly. Unfortunately, however, the reality we are facing at present is quite different from their expectations. The realized share of the mobile services in Korea last year has turned out remaining only about one percent of the total network service revenue. What are the reasons for the gap between the prospects and the reality? Starting from this question, this paper attempts to explore the generic pitfalls of the traditional number-crunching methods adopted thus far for the forecast of newly emerging market trends, and present an alternative by introducing systems thinking to the mobile Internet service market as an example, followed by its rationale as a new tool for forecasting and some reasoning about why traditional methods are no longer appropriate.

Purpose Serum Thyroglobulin measurement is a major tool for the follow-up of differentiated thyroid cancer (DTC) patients. Thyroglobulin is Normal thyroid tissue, or thyroid cancer tissue produced only. Thyroid hormone to a halt without Tg differentiation of thyroid cancer recurrence just by measuring how to decide whether there was increasing expectations if I can do it instead. Therefore, in excellent sensitivity Tg new inspection of the functional sensitivity by measuring the looked to evaluate the usefulness of reagents. Thyroidectomy is measuring the numbers Tg (total thyroidectomy) remaining thyroid ablation and radioactive iodine (radioactive iodine remnant ablation, RRA) DTC in patients being diagnosed with or help predict the remaining early detection of thyroid cancer recurrence. Materials and Methods Agent that I'm currently using Tg of the measurements of low clinical specimen for a second drainage of the three (0.08 0.17, 0.98, ng/mL) within the scope of the dilute magnification (2, 4, 8, 16, 32 times) by dilute Intraassy (n=10) and Interassay (n=10) out in no time. Concentration value according to the coefficient of variation and the mean and standard deviation of each measurement (Coefficient of variation, CV) the absolute value of the measured values that corresponds to 20 percent target a coefficient of variation of CV Find the value of the concentration of the functional sensitivity measurement did. Also, analytical sensitivity with recovery rates, Dilution test inspections, and interrelationship, compared. Results Sensitivity is an excellent analytical sensitivity within the prosecutor kit Tg 0.006 ng/mL, and core analytical sensitivity, conducted by the 0.006 ng/mL to same conclusion. Be rather high to 142 percent recovery rate was 60 to measurement and functional sensitivity, 0.01766 ng/mL(Intraassay n=10) was measured at. CBC is relatively good correlation as ($R^2=0.949$) the correlation. Conclusion Recently ultrasensitive thyroglobulin this clinically important indicators of the previous kit and demands are lower than sensitivity to the measurement results. Therefore, ultrasensitive thyroglobulin test is correlated that there would be useful in value in nuclear medicine the thyroid gland.
