This descriptive exploratory study was conducted to analyze the results of developmental screening test using DDST and the follow-up diagnostic evaluation in one public health center, and to evaluate the feasibility of developmental screening in nursing. Samples were 373 children under 6 years who visited the public health center. Mothers' satisfaction on the developmental clinic was also determined. Summaries of the results were as follows:v 1. 0.5% of children in height and 1.9% of children in weight were included in below 3 percentile of Korean children's growth chart, but none of them showed developmental delay. 2. The results of DDST showed 92.1% of subjects were classified as normal, 3.7% as abnormal, and 4.2% as questionable among 354 children. 3. Most of children who showed the abnormal development at the first DDST were confirmed having the developmental delay at the follow-up diagnostic evaluation. On the other hand, most of children who showed the questionable development at the first DDST revealed having the normal development in follow-up screening test. 4. The result of the DDST was influenced by the birth order of the subject and delivery type. 5.The mean satisfaction score by mothers on developmental clinic was 4.35 in 5 Likert scale. In conclusion, we could certain the feasibility and usefulness of developmental screening in community and child care nursing. To fulfil the increasing needs of mothers with infants on the child development, nurses have to provide anticipatory guidance and parent education in addition to the developmental screening test. We hope to expand the developmental screening in nursing field not only of clinical setting but also of community.

The objective of this study is to investigate the quality characteristics of yanggeng prepared with different amounts of Crataegi fructus extracts(CFE; 0, 5, 10, 15, 20). Increasing the amount of CFE in the yanggeng tended to increased the moisture and acidity, while it decreased the level of pH. In chromaticity determination, the values of lightness(L) and yellowness(b) showed a decrease. However, the value of redness(a) increased by increasing levels of CFE. In addition, hardness increased by increasing levels of CFE. Although regarding texture profile analysis, hardness and springiness of yanggeng were increased, adhesiveness and cohesiveness of yanggeng were decreased. Cohesiveness shown similar result compared to the control and CFE added treatments. The sensory evaluation indicated that CFE 15 showed the best preference in color, taste, texture, flavor, and overall acceptance. Based on these results, 15% should be recommended as a optimum level of CFE to be added for the preparation of yanggeng. And these results suggest that CFE may be a useful ingredient in yanggeng for improvement of the quality.

In this paper, we analyzed the optical properties of the LED module for dental care, which has the effect of promoting cell regeneration and scar treatment. The LED module is a U-shaped module suitable for the shape of teeth. It is manufactured with an LED module (632 nm) and an LED module (632 nm + 870 nm), analyzes the results of optical properties, sets the irradiation distance, irradiation time, and is effective in healing skin wounds. Evaluation was conducted. It was tested in 6 test groups according to the light irradiation conditions, and light was irradiated to the scar site every other day for 7 days, 1 day and 3 days. As a result, it was confirmed that the effect of scar treatment was the highest when the combined wavelength of 632 nm + 870 nm was irradiated in pulse mode than when the single wavelength was irradiated and the composite wavelength was continuously irradiated. In group C group irradiated with PW Mode: pulse mode (period 36 ms, pulse width 35 ms) using a composite wavelength with LED module (632 nm + 870 nm) than group A without light irradiation, the length of scar reduction was 19 %, the area of the scar was further reduced by 10%, and it was confirmed that it is effective in treating scars in the wound area.

Muscle fillets of flounder, Limanda herzensteini, were sliced into small pieces and dehydrated by the methods of sun drying, hot air drying and vacuum freeze drying, and evaluated for the protein quality by the method of shortened pepsin pancreatin digest residue (SPPDR) index which is the modified method of shortened pepsin digest residue index. In the analysis of the muscle protein hydrolysates, glutamic acid, aspartic acid and lysine comprised about 39% of the total amino acids of the protein. The content of pure protein in flounder muscle was 18.8%. The result of nutritional evaluation of the dried muscle protein by the computation of the SPPDR index showed that the freeze dried flounder muscle protein was superior in the nutritional efficiency to the others, sun dried. The freeze dried flounder muscle protein marked 89 of the SPPDR index number which is quite similar to the muscle protein of terrestrial animal in nutritional quality.

A general goal of the AT%(Asynchronous Transfer Mode) network is to support connect across various network. On ATM networks, ABR services are provided using the remained ban after allocation CBR and VBR traffic. Realtime services such as transmitting audio or video data may be provided using CBR ado VBR which have a constrained transmission delay, but in these cases, the communications bandwidth may be wasted. In this paper a simulation has been performed to compare and evaluate the performance between the ERICA(Explicit Rate Indicate Avoidance) and EPRCA(Enhanced Proportional Rate Control Algorithm) switches which use Explicit Rate switch algorithm for ABR switch. The variation of the ACR at the source end system, the queue length, the utilization rate of the link bandwidth and the share fairness at the transient and steady states are used as the evaluation criteria for the simulation. As a result of simulation, ERICA algorithm switch was ten times long compared to ERPCA switch to achieve assigned fair share. so EPRCA switch is superior to ERICA about load response. For Fair share and stability, ERICA switch is excellent to EPRCA switch.

The process of assessing environmental values and impacts is subjective and depends on predictions, limiting the securing of scientific rationality. Therefore, it is necessary to make a supplement by securing procedural rationality. This study has been tried to secure procedural rationality of EIA based on information disclosure system. The Aarhus Convention is an international treaty that defines the right of the public to access to environmental information and to participate in decision-making. This study evaluates Korean EIA information disclosure system by deriving 10 indicators based on the provisions on information disclosure presented in the Aarhus Convention. As a result, the five indicators were satisfied in terms of direction of information disclosure and provision. And the four indicators for the basis of utilization and process are required to be supplemented by detailed regulations. Finally, we derive the need for research on the asymmetry of expertise and acceptability of EIA system through public understanding indicators.

As the 4th industrial age approaches, the demand for semiconductors is increasing enough to be used in all electronic devices. At the same time, semiconductor technology is also developing day by day, leading to ultraprecision and low power consumption. Semiconductors that keep getting smaller generate heat because the energy density increases, and the generated heat changes the shape of the semiconductor package, so it is important to manage. The temperature change is not only self-heating of the semiconductor package, but also heat generated by external damage. If the package is deformed, it is necessary to manage it because functional problems and performance degradation such as damage occur. The package burn in test in the post-process of semiconductor production is a process that tests the durability and function of the package in a high-temperature environment, and heat dissipation performance can be evaluated. In this paper, we intend to review a new material formulation that can improve the performance of the adapter, which is one of the parts of the test socket used in the burn-in test. It was confirmed what characteristics the basic base showed when polyamide, a high-molecular material, and alumina, which had high thermal conductivity, were mixed for each magnification. In this study, functional evaluation was also carried out by injecting an adapter, a part of the test socket, at the same time as the specimen was manufactured. Verification of stiffness such as tensile strength and flexural strength by mixing ratio, performance evaluation such as thermal conductivity, and manufacturing of a dummy device also confirmed warpage. As a result, it was confirmed that the thermal stability was excellent. Through this study, it is thought that it can be used as basic data for the development of materials for burn-in sockets in the future.

We sought to derive an overall strategy for green business certification of medical institutions and to propose the improvement directions for green management evaluation systems through applying the criteria to medical institutions. A self-assessment survey was conducted at 44 targeted hospitals across the country, and the 2012 green management evaluation criteria for healthcare services were used as assessment tools. As a result, only 11 of the 44 hospitals were eligible for green business certification. By type, hospitals with more than 400 beds, hospitals in Seoul and the Gyeonggi area (${\geq}$ 400 beds) and private hospitals (${\geq}$ 400 beds) received relatively high scores. In an analysis of the mean score, only the difference between the hospitals with ${\geq}$ 400 beds and < 400 beds was statistically significant. When we analyzed the interviews of the hospitals with lower scores, it is important to change the awareness of executives and employees, to establish vision/strategy/objective, to promote relatively small-scale activities, and to establish long-term plans. To improve green management evaluation systems, it is necessary to reset the assessment area, to control scoring and weights, to create certification grades, and to adjust additional points.

As OWL(Web Ontology Language) has been selected as a standard ontology description language by W3C, many ontologies have been building and developing in OWL. The lena developed by HP as an Application Programming Interface(API) provides various APIs to develop inference engines as well as storages, and it is widely used for system development. However, the storage model of Jena2 stores most owl documents not acceptable into a single table and it shows low processing performance for a large ontology data set. Most of all, Jena2 storage model does not consider hierarchical structures of classes and properties. In addition, it shows low query processing performance using the hierarchical structure because of many join operations. To solve these issues, this paper proposes an OWL ontology relational database model. The proposed model semantically classifies and stores information such as classes, properties, and instances. It improves the query processing performance by managing hierarchical information in a separate table. This paper also describes the implementation and evaluation results. This paper also shows the experiment and evaluation result and the comparative analysis on both results. The experiment and evaluation show our proposal provides a prominent performance as against Jena2.
