Purpose: This study was performed to identify the effects of intraoperative music therapy on the anxiety level of adult patients undergoing local anesthesia in the operating room. Method: The research design was a nonequivalent control group pretest-posttest. Data collection was done with 48 patients undergoing local anesthesia from June 2003 to September 2()03. The 24 patients in the experimental group were given music therapy through headphones from the beginning of the operation to the end of the operation with local anesthesia. The data were analyzed using SPSS/PC 10.0 for Windows. Results: Postoperative state anxiety scores were significantly different between the experimental group and the control group. Intraoperative pulse rates were significantly different between the two groups. But systolic and diastolic blood pressures and respiratory rates were not significantly different between the two groups. Conclusion: Considering these results, music therapy can be regarded as an effective nursing intervention that relieves anxiety for adult patients undergoing local anesthesia. However, to determine the best use of this therapy, further study is required for different types of anesthesia and operations such as ambulatory surgery.

This study is a plan for the Jeju Sanghyo Botanical Garden construction, and it is prepared to maintain the identity of the local landscape by composing the garden using the local landscape resources. The goals of becoming one of world's best, garden centered botanical garden and at the same time one that represents culture of Jeju. Unusual species are included in the collection and with the general collection, special collection and exhibition by different kinds are planned to be offered to the public. The garden will demonstrate the world's various types of gardens in a compressed way. It is our endeavor to become center of culture beyond plant education and exhibition, drawing a large number of people to our garden. Moreover, conservation of Jeju's unique botanic resources will be carried out and the garden will show the garden culture. Due to the size of the site, different themes will be exhibited in one zone in a parallel. Unique combination of each local landscape resource will create own theme. The display will be divided into three different stages: the 1st stage is an educational exhibition, assisting more understanding of distinguishing different locations, the second is exhibition by various species and the final stage will show an ideal way to develop a garden with harmony of various plant species.

This paper Proposes a new couple particle swarm optimization (CPSO) for multimodal functions. In this method, main particles are generated uniformly using Faure-sequences, and move accordingly to cognition only model. If any main particle detects the movement direction which has local optimum, this particle would create a new particle beside itself and make a couple. After that, all couples move accordingly to conventional particle swarm optimization (PSO) model. If these couples tend toward the same local optimum, only the best couple would be kept and the others would be eliminated. We had applied this method to some analytic multimodal functions and successfully locate all local optima.

In the context of additive noise steganography model, we propose a method to detect least significant bit (LSB) matching steganography in grayscale images. Images are decomposed into detail sub-bands with local linear transform (LLT) masks which are sensitive to embedding. Novel normalized characteristic function features weighted by a bank of band-pass filters are extracted from the detail sub-bands. A suboptimal feature set is searched by using a threshold selection algorithm. Extensive experiments are performed on four diverse uncompressed image databases. In comparison with other well-known feature sets, the proposed feature set performs the best under most circumstances.

Altar architecture is a kind of sacrificial building, mainly formed in altar. Central architecture of Altar architecture is relatively simple. However, various attached building are necessary for worship. Among them, Sinsil which is a place to seal a God's tablet, is very important. The central government of the Joseon Dynasty attempted to define the local sacrificial system and make it customary as a way to strengthen the centralization based on Confucianism. Nonetheless, the altar architecture of the province without detailed regulations, were managed and underwent repairs according to the political situation of the state and local circumstances. Sinsil, which is an important component of the altar architecture, best reflects this situation. Therefore, it was possible to grasp the situation of the altar architecture of the province in the Joseon Dynasty by analyzing the Sinsil through various documents. As a result of analysis, it was divided into six types. In addition, It is also found that there are temporal relation between these six types.

The objective of this paper is to define local optimization algorithms (LOA) to solve Resource-Constrained Project Scheduling Problem (RCPSP) and analyze the performance of these algorithms. By representing solutions with activity list, three primitive LOAs, i.e. forward and backward improvement-based, exchange-based, and relocation-based LOAs are defined. Also, combined LOAs integrating two primitive LOAs are developed. From the experiments with standard test set J120 generated using ProGen, the FBI-based LOA demonstrates to be an efficient algorithm. Moreover, algorithms combined with FBI-based LOA and other LOA generate good solutions in general. Among the considered algorithms, the combined algorithm of FBI-based and exchangebased shows best performance in terms of solution quality and computation time.

Optimization in the engineering design is to select the best of many possible design alternatives in a complex design space. One major problem of local minimization algorithm is that they often result in local optima. In this paper, a hybrid method was developed by coupling the genetic algorithm and a traditional direct search method. The proposed method first finds a region for possible global optimum using the genetic algorithm and then searchs for a global optimum using the direct search method. To evaluate the performance of the hybrid method, it was applied to three test problems and a problem of designing corrugate bulkhead of a ship.

Dipterocarps or Dipterocarpaceae is a commercially important timber producing and dominant keystone tree family in the rain forests of Borneo. Borneo's landscape is changing at an unprecedented rate in recent years which affects this important biodiversity. This paper attempts to model the natural occurrence (distribution including those areas with natural forests before being converted to other land uses as opposed to current distribution) of dipterocarp species in Sarawak which is important for forest biodiversity conservation and management. Local modeling method of Inverse Distance Weighting was compared with commonly used statistical method (Binary Logistic Regression) to build the best natural distribution models for three genera (12 species) of dipterocarps. Database of species occurrence data and pseudoabsence data were constructed and divided into two halves for model building and validation. For logistic regression modeling, climatic, topographical and edaphic parameters were used. Proxy variables were used to represent the parameters which were highly (p>0.75) correlated to avoid over-fitting. The results show that Inverse Distance Weighting produced the best and consistent prediction with an average accuracy of over 80%. This study demonstrates that local interpolation method can be used for the modeling of natural distribution of dipterocarp species. The Inverse Distance Weighted was proven a better method and the possible reasons are discussed.

From the evaluation of physical properties such as springiness, gumminess, adhesiveness, chewiness and hardness by the texture analyzer, vegetable soybean lines with green seed-coat were best as compared with those with black, brown, mixed, and yellow seed-coats. A panel test evaluated on the basis of taste, sweetness, chewiness, and total scores also indicated that soybean lines with green seed-coat were the best. The total scores of panel test was decreased in the order of green > yellow> black> brown seed-coat colored soybean. The mean value of sucrose content obtained by HPLC analysis was highest in black seed-coat colored soybean, and followed by green, yellow, and brown soybeans. The highest sucrose content (8.22%) was observed in 180362, a soybean line with green seed-coat. The full-season type soybeans showed much higher sucrose content than summer types which are mainly cultivated on farmer's fields for vegetable purposes. The final 13 lines selected from 300 colored soybeans showed nearly the same panel scores as Miwongreen. However, these lines had a great deal of variation in sucrose content, and much higher readings in texture analysis than Miwongreen, especially in chewiness and hardness which were the most important properties in vegetable soybeans.
