Purpose: This study was conducted to examine the effects of the nurse-led one-on-one discharge education on the levels of symptom experience and self-care compliance among patients with chronic obstructive pulmonary disease (COPD) who had not previously participated in an education or respiratory rehabilitation program. Methods: This study used a quasi-experimental pre-and post-test design with nonequivalent control group. Sixty seven hospitalized patients (34 for experimental and 33 for control groups) were recruited from in-patient units of a general hospital from August to November, 2010. The one-on-one education session of symptom management and daily self-care was administered to experimental group for 50 minutes along with a follow-up phone call. Self-administered questionnaire was administered at the pretest and at 1 month after discharge. Results: The subjects were 67.43(${\pm}10.24$)years old in average. The mean differences of symptom experience (t=3.39, p=.001) and self-care compliance (t=-38.13, p<.001) in the experimental group was significantly higher than those of the control group. Conclusion: Nurse-led one-on-one discharge education was effective in reducing the level of symptom experience and enhancing self-care compliance at home within one month after discharge. Therefore, this form of one-on-one education provided by nurses might be applicable effectively for COPD patients who do not have access to respiratory rehabilitation programs.

Objectives : This study aims to investigate the background of, and theoretical system behind the Jinkuiyuhanjing that was edited and published at the same time as the Shanghanlun by the Jiaozhengyishuju (governmental publishing sector) of Northern Song. Methods : To determine the background against which Jinkuiyuhanjing was published, its position and meaning within the Medical Texts Editing Project of the Jiaozhengyishuju was firstly examined. For its theoretical background, the contents of Zhengzhizongli, which is considered to be an introduction to the Jinkuiyuhanjing was thoroughly analyzed. Moreover, to understand the unique philosophy of the Jinkuiyuhanjing, referneces were made to relevant contents in the 'Shinhyeong' chapter of the Donguibogam. Results : The findings of the study call for a re-evluation of the Jinkuiyuhanjing as holding a unique philosophical perspective and having an independent lineage instead of being a supplementary material to the Shanghanlun as it was once understood. Conclusions : The research of Zhangzhongjing's Classical Formulas(經方) revealed that the theoretical thinking and contents of Jinkuiyuhanjing hold much value and should be actively studied and applied. Furthermore, it lends important meaning in understanding the tradition of Korean Classical Formulas as represented in the Donguibogam.

The authors adopt the Unmanned Undersea Vehicle(UUV), which has taken the shape of manta(Sohn et al. 2006). They call here it Manta-type Unmanned Undersea Test Vehicle(MUUTV). MUUTV is designed with the similar concept of UUV called Manta Test Vehicle(MTV), which was originally built by the Naval Undersea Warfare Center, USA(Lisiewicz and French 2000, Sirmalis et al. 2001, U.S. Navy 2004). The present study deals with evaluation of extreme motion of MUUTV at large attack angles. Extreme motion contains, for example, rising and depth change due to operation of hovering thrusters attached to MUUTV, lateral motion due to ocean current applied to MUUTV at low advance velocity, and so on. Numerical simulation technique has been utilized. The previous mathematical model on manoeuvring motion of MUUTV(Bae et al. 2009a) is basically adopted. Based on the results of present model experiment on extreme motion, the mathematical model is revised and supplemented in order to describe extreme motion. The hydrodynamic derivatives related to extreme motion are obtained from present model experiment and the other derivatives are referred to previous work(Bae et al. 2009a).

In this paper, we propose a virtual action system based on information agents, We call the system the MultiHammer, MultiHammer can be used for studying and analyzing online actions. MuiltiHammer provides functions of implement-ing a meta online action site and an experiment environ-ment. We have been using MultiHammer as an experiment as an experiment environment for BiddinBot. BiddingBot aims at assisting users to bid simultaneously in multiple online auctions. In order to bid simultaneously in multiple online auctions. In order to analyze the behavior of BiddngBot, we need to pur-chase a lot of items. It is hard for us to prepare a lot of fund to show usability and advantage of BiddingBot. MultiHam-mer enables us to effectively analyze the behavior of BiddingBot. MultiHammer consists of three types of agents for information collecting data storing and auctioning. Agents for information wrappers. To make agent work as wrarp-pers, we heed to realize software modules for each online action site. Implementing these modules reguires a lot of time and patience. To address this problem, we designed a support mechanism for developing the modules. Agents for data storing record the data gathered by agents for informa-tion collecting. Agents for auctioning provide online services using data recorded by agents for data storing. By recording the activities in auction sites. MultiHammer can recreate any situation and trace auction for experimentation, Users can participate in virtual using the same information in real online auctions. Users also participate in real auc-tions via wrapper agents for information collecting

Early predictions of crop yields call provide information to producers to take advantages of opportunities into market places, to assess national food security, and to provide early food shortage warning. The objectives of this study were to identify the most useful parameters for estimating yields and to compare two model selection methods for finding the 'best' model developed by multiple linear regression. This research was conducted in two 65ha corn/soybean rotation fields located in east central South Dakota. Data used to develop models were small temporal variability information (STVI: elevation, apparent electrical conductivity $(EC_a)$, slope), large temporal variability information (LTVI : inorganic N, Olsen P, soil moisture), and remote sensing information (green, red, and NIR bands and normalized difference vegetation index (NDVI), green normalized difference vegetation index (GDVI)). Second order Akaike's Information Criterion (AICc) and Stepwise multiple regression were used to develop the best-fitting equations in each system (information groups). The models with $\Delta_i\leq2$ were selected and 22 and 37 models were selected at Moody and Brookings, respectively. Based on the results, the most useful variables to estimate corn yield were different in each field. Elevation and $EC_a$ were consistently the most useful variables in both fields and most of the systems. Model selection was different in each field. Different number of variables were selected in different fields. These results might be contributed to different landscapes and management histories of the study fields. The most common variables selected by AICc and Stepwise were different. In validation, Stepwise was slightly better than AICc at Moody and at Brookings AICc was slightly better than Stepwise. Results suggest that the Alec approach can be used to identify the most useful information and select the 'best' yield models for production fields.

In Korean language, 'changeu'(originality) and 'changjo'(creativity) has been used as almost same meaning, because these have similar pronunciation. However, originality means idea and creativity means process. The former is based on intuition, and the latter is on both of logic and intuition. Intuition process is not perceived very well, but logic has very clear one. We can find the due for that creating something is not difficult too much anymore, because the process is identified. The creation process is a problem solving process and it has the design on its center. Designer study the problem solving process and learn how to solve the problem with many cases on its studio class. Then we can call them as a creator. The meaning of design that it is a styling is very usual in Korean public and even designers. However, it will be not valid anymore in the upcoming digital age, which reproduction is possible with a little restriction. Design should be back as an original methodology for creation with the designer's own capability such as conception, intermediation, and visualization.

The purpose of this research is to evaluate the quality of Differential Police Response strategy. Although it has been approximately three years since these new police response systems were introduced, there is no research to evaluate them empirically. Using two types of statistical quality control techniques, Xbar-R control charts for variables data and P charts for attributes data, this study analyzes approximately 3,000 calls reported throughout the year 2012 to the 112 Integrated Dispatch Center in Ik-san police station. The Xbar-R control charts revealed that the police did not consistently respond to an emergency call for service (i.e., code one case) within 3 minutes. The P control chart also identified that there was a significant variation in the portion/number of defective calls where police failed to respond to non-emergency calls for service within 5 minutes. The results from this study suggest the police may need to review the target response time for code 1 and code 2 respectively.

Purpose: The purpose of this study was to investigate the relationships between the herbal medicines used for women in puerperium on postpartum care, Kami-Saenghwatang(SHT) and Kami-Bohertang(BHT) and postpartum body composition change. We also examined the influence of gestational age, the number of parity and the route of delivery for gestational weight gain and postpartum weight loss. Methods: 239 women followed by postpartum care center. Variety factor s were conformed and then checked body composition analysis. 8 weeks later, we followed up body composition of 36 women among the former checked. and additionally asked the body weight of another 42 former checked women by telephone call. Results: $Mean{\pm}S.D$(standard deviation) of pre-pregnancy weight is $55.22{\pm}8.98kg$, $Mean{\pm}S.D$ of gestational maximun weight is $69.26{\pm}9.77kg$, $Mean{\pm}S.D$ of weight loss in postpartum 8 weeks(means sub-tract postpartum 1 week weight from postpartum 8 week weight) is $57.86{\pm}8.60kg$. The number of parities had corrrelation with gestational weight gain. Age, number of parities and route of delive were not significantly correlated with postpartum weight loss during 8 weeks after delivery, and also it was not correlated with body water mass, body fat mass, body mass index and body weight on postpartum 8 weeks whether they treated with SHT and BHT. conclusion: It was not correlated with body water mass, body fat mass, body mass index and body weight on 8 weeks postpartum whether they treated with SHT and BHT.

Planarization of the free-standing diamond film surface as smooth as possible could be obtained by using the hydrogen plasma etching with the diffusion of the carbon species into the metal alloy (Fe, Cr, Ni). For this process, we placed the free-standing diamond film between the metal alloy and the Mo substrate like a metal-diamond-molybdenum (MDM) sandwich. We set the sandwich-type MDM in a microwave-plasma-enhanced chemical vapor deposition (MPECVD) system. The sandwich-type MDM was heated over ca. 1000 $^{\circ}C$ by using the hydrogen plasma. We call this process as the hydrogen plasma etching with carbon diffusion process. After etching the free-standing diamond film surface, we investigated surface roughness, morphologies, and the incorporated impurities on the etched diamond film surface. Finally, we suggest that the hydrogen plasma etching with carbon diffusion process is an adequate etching technique for the fabrication of the diamond film surface applicable to electronic devices.
