Purpose: The purpose was to develop a preliminary scale to measure Korean adolescents' health behaviors through a qualitative approach, to evaluate the scale psychometrically, and to develop a final scale. Methods: Participants were 61 adolescents for qualitative interviews and 1,687 adolescents for the psychometric evaluation. Procedure included content analysis of interviews to identify health behavior categories for Korean adolescents, pre-test to confirm that preliminary scale items were understandable, content validity by an expert panel, development of the web-based computer-assisted survey (CAS), and psychometric analysis to determine reliability and validity of the final scale. Results: A final scale was developed for both paper-and-pencil and CAS. It consisted of 14 health behaviors (72 items), including stress and mental health (10), sleep habits (5), dietary habits (12), weight control (4), physical activity (4), hygiene habits (5), tobacco use (5), substance use (2), alcohol consumption (4), safety (4), sexual behavior (9), computer use (3), health screening (4), and posture (1). Conclusion: The scale's strong points are: 1) Two thirds of the final scale items are Likert scale items, enabling calculation of a health behavior score. 2) The scale is appropriate to Korean culture. 3) The scale focuses on concrete health behaviors, not abstract concepts.

This paper presents the choice of appropriate sets of input variables for large-scale linear multivariable systems. It is shown that the selection of a good set of input variables for control may become important when both strong and weak input variables are available. The transmission of information from the inputs to the outputs is investigated and appropriate scaling procedures to derive a scaled input matrix are proposed. Singular value decomposition methods facilitate the quantification of the systems excitation stemming from the various input variables, and thus the selection of an appropriately strong and orthogonal set of input variables. The need for and the implementation and benefits of reducing the number of input variables are illustrated by a large-scale steam generator model of a real process.

This review aimed to assist clinicians in the identification and assessment of adult attention-deficit hyperactivity disorder (ADHD) with an emphasis on diagnostic and rating instruments. Pubmed and RISS were utilized to identify relevant studies and critical reviews on the diagnosis and assessment of adult ADHD, published between 1988 and 2010. The Adult ADHD Self-Report Scale-v1.1, the ADHD Rating Scale-IV, the Conners Adult ADHD Rating Scale, and the Current Symptoms Scale have been utilized for self-reporting of current ADHD symptoms. The Brown ADD Rating Scale, the ADHD Rating Scale-IV, the Current Symptoms Scale, and the Conners Adult ADHD Rating Scale have also been evaluated by an observer. The Childhood Symptom Scale and the Wender-Utah Rating Scale have been used for retrospective assessment of childhood ADHD symptoms and the Adult ADHD Investigator Symptom Rating Scale, the Adult Interview, the Brown ADD Diagnostic Form, the Conners adult ADHD diagnostic interview for DSM-IV, and the Wender-Reimherr Interview have been available as comprehensive diagnostic interviews. There is a wide variety of instruments available with respect to adult ADHD. The choice of appropriate instruments is essential for achieving accurate diagnosis and assessment of this disorder.

This paper proposes a novel desktop virtual reality system. Based on the position of the user's face, the proposed system selects the most appropriate image of an object from a set of photographs taken at various angles, and simply "pastes" it onto the display at the appropriate location and scale. Using this system, the users can intuitively feel the presence of the object.

The advanced driver assistant system (ADAS) requires the collection of a large amount of information including road conditions, environment, vehicle status, condition of the driver, and other useful data. In this regard, large-scale sensor networks can be an appropriate solution since they have been designed for this purpose. Recent advances in sensor network technology have enabled the management and monitoring of large-scale tasks such as the monitoring of road surface temperature on a highway. In this paper, we consider the estimation and fusion problems of the large-scale sensor networks used in the ADAS. Hierarchical fusion architecture is proposed for an arbitrary topology of the large-scale sensor network. A robust cluster estimator is proposed to achieve robustness of the network against outliers or failure of sensors. Lastly, a robust hierarchical data fusion scheme is proposed for the communication channel between the clusters and fusion center, considering the non-Gaussian channel noise, which is typical in communication systems.

The safety of pile foundation is getting declined when the pile foundation acting on lateral load is exposed by dredging. So appropriate reinforcement is needed for stability secure. Thus, in this study, the stability variation and reinforcement range caused by dredging is estimated on the basis of down scale test. The scale effect is determined by real scale numerical analysis. the behavior of pile by dredging stages is estimated by load control type. The credibility is verified through the comparison between down scale model test and numerical analysis.

The purpose of this study was to examine the feasibility and validity of the Application of Cognitive Function Scale as developed by Lidz and Jepsen (1997). Data were collected from 4 to 5-years-old children. The analysis for item adequacy indicated that the passing rate increases according to age. Futhermore the analysis for test adequacy indicated that internal consistency reliability was .85 in the pre-test and .80 of post-test in terms of the cognitive function scale, and .90 of pre-test and .93 in the post-test in relation to the behavior observation scale. In conclusion, our analysis of the ACFS shows sufficiently high scores in terms of both validity and reliability, so as to indicate that this test is an appropriate way to measure the cognitive function and non-intellective function of young Korean children.

본 연구는 유아교사의 동료장학과 교사발달을 위한 동료 평가 척도개발을 목적으로 실시되었다. 선행연구에서 유아교사 평가척도에 대한 연구는 많이 논의되어 왔으나, 평가자는 주로 원장 또는 상급자에 의해 일시적인 평가나 자기평가로 이뤄져왔다. 본 연구에서는 주변 동료교사를 통해 유아교사 평가가 이뤄질 수 있도록 문항을 개발하였다. 동료교사를 통한 평가는 교사의 지속적인 모습을 평가할 수 있기 때문에 교사에 대해 보다 세밀하게 평가가 이뤄질 수 있다는 점에서 장점이 있다고 볼 수 있다. 본 논문에서는 51개 문항을 가지고 동료 평가를 실시하였는데, 9개 영역으로 분리하여 150명을 대상으로 설문조사를 실시하였다. 이를 위해 척도의 적절성(내용타당도, 구인타당도, 문항내적합치도)과 문항의 적절성(문항변별도)을 분석하였다. 분석 결과 동료 유아교사 평가 문항으로서 적절한 척도임을 알 수 있었다.

Purpose: To develop and validate a scale suitable and efficient scale for use in clinical practice as to assess pain in premature infants. Method: Pain indicators identified by observation of preform infants. A cohort of preform infants was studied prospectively to determine the construct validity, inter-rater reliability, and internal consistency of the scale. The PIPS uses four indicators of pain: corrected gestational age, heart rate, oxygen saturation, behavioral state. The validation study included 45 premature infants with gestational age of 37 weeks or less. Results: The inter-rater reliability of the PIPS was acceptable, with Pearson correlations ranging from.720 to.970. Internal consistency was high: Cronbach's alpha coefficients ranged from.551 to.653. There was a strong correlation between the PIPS and PIPP scores (each researcher's r=.743, each indicator's r=.914). Although gestational age showed no association between these factors and the sum, the other variables were positively associated with the sum. Time needed to calculate PIPS scores is was less than Premature Infant Pain Profile (PIPP) scores(p<.000). Conclusion: The validation data suggest that the PIPS is appropriate and efficient for assessing pain in premature infants. Further studies are required about to determine appropriate interventions for each pain score on the PIPS.

Hemolymph is oxidized and darkens visibly during the collection from silkworm due to the activity of tyrosinase in it. Toxic quinones are produced by the oxidation and consequently inhibit the cell growth. Heat treatment can be used to prevent the oxidation ; however, the oxidation may occur during the collection of hemolymph before it is heat-treated. It makes the hemolymph collection difficult especially on a large-scale preparation. Hemolymphs collected from 257 different strains of silkworms were examined to select the slowly oxidized hemolymphs. Hemolymphs collected from mutant strains such as Lemone, TBO, Cre, Y4, and wEb showed relatively slow color changes. Oxidation rates of the hemolymphs were measured by the absorbance change using a spectrophotometer. The hemolymph of wEb showed the slowest oxidation. The absorbance of this mutant hemolymph reached the saturation value at 20$^{\circ}C$ in 450 min, whereas the total oxidation time of the wild-type (Baekokjam) hemolymph at the same temperature was 120 min. We tested if this mutant hemolymph is useful as a medium supplement for insect cell culture. Cell growth rate and final cell concentration in the medium supplemented with the wEb hemolymph were almost same as those in the medium supplemented with the wild-type hemolymph. Hemolymph is collected on a small scale by clipping the abdominal leg; however, this method is not appropriate fro large scale preparation. Centrifugation after chopping the silkworm hemolymph by a blending mixer is a more appropriate procedure for large scale collection. Slowly oxidized wEb hemolymph resulted in higher cell concentration than the wild-type hemolymph when hemolymph was collected by the large scale preparation method.
