A method is described for ideally reconstructing the profile from a surface profiling measurement containing a reasonable amount of null measurement data. The proposed method can conjecture lost information and rectify irregular data that result due to bad measuring environments, signal transmission noise, or instrument-induced errors, The method adopts the concept of computer graphics and consists of several processing steps. First, a search for valid data in the neighborhood of the null data is performed. The valid data are then grouped and their contours are extracted. By analyzing these contours, a bounding box can be obtained and the general distribution of the entire area encompassing the valid and null data is determined Finally, an ideal surface model is overlaid onto the measurement results based on the bounding box, generating a complete reconstruction of the calculations, A surface-profiling task on a liquid crystal display photo spacer is used to verify the proposed method. The results are compared to those obtained through the use of a scanning electron microscope to demonstrate the accuracy of the proposed method.

The purpose of this paper is to explain the process of developing and validating the instrument to measure the university's organizational core values and sub-values known as ESI iDART. The three core values are excellence, synergy, and integrity, while the five sub-values comprise knowledge, discipline, trustworthiness, diligence, and responsibility that all staff should understand and practice. These values must be measured to examine the extent to which the staff has practiced them in their work life. With regard to methodology, the research instrument used in the study was developed using a focus group study involving 39 university staff from various departments and campuses. The instrument was later refined and validated by a group of experts from the university. In the main study, the instrument was distributed to all 17,969 university staff from all over the country. After one month, a total of 11,688 university staff participated in the survey indicating a 66% response rate. Using descriptive analysis, reliability analysis, and ANOVA, the results indicate that instrument is considered valid and reliable to be used. The major findings from the study show that organizational values increase over time. Some theoretical and managerial implications are also discussed.

Purpose: This integrative review study was done to analyze methods used for validation studies in Korean nursing research. Methods: In this study, the literature on instrument development in nursing research from Research Information Sharing Service (RISS) and major nursing journal databases in Korea were examined. The MeSH search terms included 'nursing', 'instrument', 'instrument development', 'validation' and 189 articles were included in the review. Results: The most frequently reported validity type was content validity, followed by construct validity, and criterion validity. One third reported a single type of validity, and 15% of the studies demonstrated three kinds of validity at the same time. In about 40% of the studies, both content and construct validity were examined. Conclusion: The results of the study indicate that it is necessary to provide a wider variety of evidence to establish whether instruments are valid enough to use in nursing research.

A new method is developed to estimate the evaporation of water from a surface with high accuracy and resolution. The principle of new method is to detect a weight change of buoyant weight according to a change in water level of Class A Pan mesured by the use of a strain-gauge load cell. Field test of evaporation recording new instrument was carried out at Suwon for 10 days July 1999. It is possible in field observation to measure hourly evaporation amount by newly developed evaporation recording instrument in Class A Pan against strong solar radiation. Present study provide a possibility of domestic high accuracy instrument development below than 0.1mm water level measurement accuracy. If there is low humidity and high wind speed conditions which is possible to evaporate from water surface during night time. And it needs continuous study to understand between meteorological elements and latent heat effect at ground level by field observation study using high accuracy evaporation recording instrument.

Purpose: The purpose of this study was to develop an instrument to measure the parenting behavior of primary caregivers of children in early childhood. Methods: An instrument was developed according to Devellis's instrument development process. The participants in this study who completed the main survey were 370 mothers and grandmothers. The survey was conducted from June 1 to July 30, 2014, and collected data were analyzed using item analysis, half-split reliability and Cronbach's ${\alpha}$ coefficient, exploratory and confirmatory factor analysis, convergent validity. Results: The factor structure of the instrument showed the cumulative variance as 55.7% in the factor analysis. As a result of a confirmatory factor analysis, a four-factor structure was found to be appropriate, and the construct validity and convergent validity of the instrument were thereby confirmed. The finalized parenting behavior instrument consisted of 26 items and four independent factors: affectionate, laissez-faire, educational and impulsive. A five-point Likert scale was employed, and a higher score in a particular factor showed that most of the behaviors belonged to the factor. Conclusion: The instrument developed in this study was found to be reliable and valid, and can be used to develop parent-child relationship building.

The Korea Astronomy and Space Science Institute is participating as a South Korean partner in the Commercial Lunar Payload Services (CLPS)of NASA. In response, the Korea Astronomy and Space Science Institute is currently conducting basic research for the development of four candidate instrument payloads. The magnetic field instrument is one of them and it's scientific mission objective is the moon's surface magnetic field investigation. Therefore, the development requirement of the lunar surface magnetic field instrument were derived and the initial conceptual design was started. The magnetic field instrument has a 1.2 meter boom which has two three-axis fluxgate magnetometer sensors and one gyro sensor to get a attitude information of the boom. The concept of measuring the lunar surface magnetic field will carry out using multiple sensors by placing semiconductor type magnetic field sensors inside the electric box including boom mounted fluxgate sensors. In order to overcome the very short development period, we will use the KPLO (Korean Lunar Pathfinder Orbiter) magnetometer design and parts to improve reliabilities for this instrument. In this presentation, we introduce the instrument requirements and conceptual design for the Lunar surface magnetic field instruments.
