The purpose of this case study is to provide the basic knowledge and the rationale for establishing the professional personnel position of Landscape Architecture(LA) in local Government of Korea o the basis of the characteristics and adoption system of professional personnel organization in comparison with the cases of Japan, the United States of America, and Germany. I have analyzed the case of Chonju City, Chollabuk-Do, recruited professional personnel of LA by using informal career position, to justify the needs and the division of professional Landscaping works of the city and to figure out drawbacks of the current adoption system of professional personnel in South Korea. In have found the following results that 1) City Mayor in Korean local Governments do not have the proper authorizing rights of recruiting the special personnels for performing urban policy, which is under controls of the Official Appointment Regulations, 2) because of no official position status for specialist in the fields of LA, the Chonju City had been recruited them as Urban Planner status through an informal process, 3) the section of Park and Urban Forestry was established under the control of Department of Culture and multimedia Industry, 4) the fields of specialized works of LA are defined as the work of ecopolis design and planning, biotope networking, ecological bridge and ecological restorations, and 5) the professional positions for LA should be established in Official Appointment Regulation for the urgent needs of local Government sin South Korea.

The Error Back-Propagation(EBP) algorithm is widely applied to train a multi-layer perceptron, which is a neural network model frequently used to solve complex problems such as pattern recognition, adaptive control, and global optimization. However, the EBP is basically a gradient descent method, which may get stuck in a local minimum, leading to failure in finding the globally optimal solution. Moreover, a multi-layer perceptron suffers from locking a systematic determination of the network structure appropriate for a given problem. It is usually the case to determine the number of hidden nodes by trial and error. In this paper, we propose a new algorithm to efficiently train a multi-layer perceptron. OUr algorithm uses stochastic perturbation in the weight space to effectively escape from local minima in multi-layer perceptron learning. Stochastic perturbation probabilistically re-initializes weights associated with hidden nodes to escape a local minimum if the probabilistically re-initializes weights associated with hidden nodes to escape a local minimum if the EGP learning gets stuck to it. Addition of new hidden nodes also can be viewed asa special case of stochastic perturbation. Using stochastic perturbation we can solve the local minima problem and the network structure design in a unified way. The results of our experiments with several benchmark test problems including theparity problem, the two-spirals problem, andthe credit-screening data show that our algorithm is very efficient.

As the WTO system launches through the agreement of Uruguay Round, the Government has to revise the office regulations or reform the system. Also, Integrating and Coordinating the like affair in health care (i. e., children's home, industry health, school health, health manpower, the administration of health center, the administration on food hygiene, health environmental education, and so on.) which is now scattered into some government departments like the Ministry of Labor, the Ministry of Education, the Ministry of Home Affairs, the Ministry of Agriculture, and the Ministry of Environment, the Government has to prevent unspecialty, inefficiency, inconsistency, and uneconomy. The Government has to review and adopt above suggested the Proposal 1),2),3),4) of the Health Centers on the basis of the local autonomy law and it will help the successive settlement of the local autonomy system in Korea. According to the suggested proposal, the Central Government mainly takes charge of the Macro affairs as hardware, and transfer the Micro affairs as software into the Local Governments to attempt the appropriate functional allocation. To achieve it successfully, the Central Government also has to do the financial support, manpower training and technical support, allocation of health care resources, direction and control, research and development and the health care plan on the macro level. Local Governments which divided into the wide local government and basic local government also have to do their best for health improvement of the community societies like plan of health care program, implementation of health care service program, taking charge of the affairs of health insurance, activation of community residents' participation and security of health care resources etc. To achieve this goal, the Government have to be more active and reformative, the related social and health agencies and educational agencies have to cooperate and support for the goals, and especially, the community residents have to participate actively and voluntarily, When all these conditions promote, local health care administration will be developed, and health level of community residents will be secured. And going one step forward, the country and people will be more healthy

Background: The pain caused by local anesthetic injection can lead to patient anxiety prior to surgery, potentially necessitating sedation or general anesthesia during the excision procedure. In this study, we aim to compare the pain relief efficacy and safety of using a digital automatic anesthetic injector for local anesthesia. Methods: Thirty-three patients undergoing excision of a benign soft tissue tumor under local anesthesia were prospectively enrolled from September 2021 to February 2022. A single-blind, randomized controlled study was conducted. Patients were divided into two groups by randomization: the experimental group with digital automatic anesthetic injector method (I-JECT group) and the control group with conventional injection method. Before surgery, the Amsterdam preoperative anxiety information scale was used to measure the patients' anxiety. After local anesthetic was administered, the Numeric Pain Rating Scale was used to measure the pain. The amount of anesthetic used was divided by the surface area of the lesion was recorded. Results: Seventeen were assigned to the conventional group and 16 to the I-JECT group. The mean Numeric Pain Rating Scale was 1.75 in the I-JECT group and 3.82 in conventional group. The injection pain was lower in the I-JECT group (p< 0.01). The mean Amsterdam preoperative anxiety information scale was 11.00 in the I-JECT group and 9.65 in conventional group. Patient's anxiety did not correlate to injection pain regardless of the method of injection (p= 0.47). The amount of local anesthetic used per 1 cm² of tumor surface area was 0.74 mL/cm² in the I-JECT group and 2.31 mL/cm² in the conventional group. The normalization amount of local anesthetic was less in the I-JECT group (p< 0.01). There was no difference in the incidence of complications. Conclusion: The use of a digital automatic anesthetic injector has shown to reduce pain and the amount of local anesthetics without complication.

This paper resents a discrete-time model of an edge-following with accommodation force control. Since an irregular workpiece shape causes disturbances to the system while following an edge, the use of preview control is proposed to improve the system performance. The preview control employs future information of the workpiece contour shape, and it can be developed by LQ-optimal control principles. This study provides a general method how to utilize the local future information obtained by the finite preview to minimize an optimality criterion evaluated over a problem duration. The force controller is designed based on the preview control scheme, and then implemented on a VME-based computer. Experimental results using an industrial robot show that the preview control system achieves faster tracking speed and better force regulation than the conventional nonpreview control system.

Content-based image retrieval is the research of images from database, that are visually similar to given image examples. Gabor functions and Gabor filters are regarded as excellent methods for feature extraction and texture segmentation. However, they have a disadvantage not to perform well in case of a rotated image because of its direction-oriented filter. This paper proposes a method of extracting local texture features from blocks with central interest points detected in an image and a rotation invariant Gabor wavelet filter. We also propose a method of comparing pattern histograms of features classified by VQ (Vector Quantization) among images.

Grid technologies make it possible for IT resources to be shared across organizational and security domains. The traditional identity-based access control mechanisms are unscalable and difficult to manage. Thus, we propose the FAS (Federation Agent Server) model which is composed of three modules: Certificate Conversion Module (CCM), Role Decision Module (RDM), and Authorization Decision Module (ADM). The proposed FAS model is an extended Role-Based Access Control (RBAC) model which provides resource access capabilities based on roles assigned to the users. FAS can solve the problem of assigning multiple identities to a shared local name in grid-map file and mapping the remote entity's identity to a local name manually.
