For guaranteeing the international competitive power of SW industry that is the core industry for the future, the training of SW technical manpower as an architect is needed. They must confront the change of worldwide technology and also lead the design and analysis of SW industry for the future. However, SW technical manpower based on regular career tends to change his employment as a general manager in current status. For solve this situation and reconsider the quality level of SW technical manpower, we need to propose the systematic and effective growth direction for them. Therefore, we propose the systematic and effective growth direction for domestic SW technical manpower and a plan to be realized by suggesting the carrier path of high level SW analysis/design manpower in this paper.

In order to realize the benefits of ITSM, it is necessary to institutionalize ITSM into the organizational culture. Currently, efforts to routinize ITSM lack in practice, and research in this area is also lacking. This study identifies the factors affecting the routinization of ITSM through literature review and interviews with experts, selects a company that has successfully routinized ITSM, and analyses the activities, methods, and procedures employed by the company on the factors in detail. The specific factors analyzed in the study include fulfillment of the customer requirements, top management support, communication, change management, training and education, quality of the ITSM system, and capability of the personnel. Important points verified in this study is that in order to realize organizational performance from ITSM, just the adoption of ITSM is not enough, but the routinization of ITSM through continuous and systematic management and improvement with the support of top management are required. Since this study is a descriptive case study, results of the study cannot be generalized. However, the study will provide practical information that can be referenced by the organizations attempting to routinize ITSM. In addition, results of the study will provide a basis of future research in ITSM.

The full automation of welding has not yet been achieved partly because the mathematical model for the process parameters of a given welding task is not fully understood and quantified. Several mathematical models to control welding quality, productivity, microstructure and weld properties in arc welding processes have been studied. However, it is not an easy task to apply them to the various practical situations because the relationship between the process parameters and the bead geometry is non-linear and also they are usually dependent on the specific experimental results. Practically, it is difficult, but important to know how to establish a mathematical model that can predict the result of the actual welding process and how to select the optimum welding condition under a certain constraint. In this paper, an attempt has been made to develop an neural network model to predict the weld top-bead height as a function of key process parameters in the welding. and to compare the developed model and a simple neural network model using two different training algorithms in order to select an optimal neural network model.

Rain attenuation and intercell interference are two crucial factors in the performance of broadband wireless access networks such as local multipoint distribution systems (LMDS) operating at frequencies above 20 GHz. Power control can enhance the performance of downlink CDMA-based LMDS systems by reducing intercell interference under clear sky conditions; however, it may damage system performance under rainy conditions. To ensure robust operation under both clear sky and rainy conditions, we propose a novel power-control scheme which applies an adaptive neuro-fuzzy inference system (ANFIS) for downlink CDMA-based LMDS systems. In the proposed system, the rain rate and the number of users are two inputs of the fuzzy inference system, and output is defined as channel quality, which is applied in the power control scheme to adjust the power control region. Moreover, ITU-R P.530 is employed to estimate the rain attenuation. The influence of the rain rate and the number of users on the distance-based power control (DBPC) scheme is included in the simulation model as the training database. Simulation results indicate that the proposed scheme improves the throughput of the DBPC scheme.

Purpose: This study was done to provide basic data for developing an in-service education program to improve nurses' quality. First, frequency of nursing activities and competency levels of emergency nurses according to their career ladders were compared through job analysis and then practical education programs were presented on based of the results. Method: Data were collected from 335 nurses working in emergency rooms in 31 tertiary hospitals. Data collection was done from September to November 2005 using the job analysis questionnaire. Results: There were 41 nursing activities that showed differences in frequency and 78 activities that showed differences in perceived competency level. Irrespective of emergency nurses' careers, activities that show high frequency but low competency were sputum liquefying therapy, assessment of cranial nerve function, identification of diagnostic radiology, and communication with various departments. In-service education content according to nurse's career ladders was presented by adding high frequency nursing activities and activities with low competency level even though having high frequency. Conclusion: There is a need to develop and provide in-service education programs, which consider nurses' difference in frequency and competency level for their career ladders.

Purpose: This study was to examine the effects of an exercise program for middle-aged obese women. Method: The exercise program combined folk dance and resistance training. The subjects group consisted of 85 middle-aged obese women between 40 and 60 years of age. Three 8 week sessions consisted of a $55-80\%$ maximum heart rate (MHR) exercise for 60-90 minutes a day and 3 times a week from March to November, 2004. Data was collected through a pre- and post-exercise test before and after each session. Data was collected with Inbody, dynamometer and blood. This data was analyzed by descriptive statistics, and a paired t-test with an SPSS/PC(10.0 version) program. Results: There were significant positive changes in body weight, body fat mass, body mass index, percent body fat, muscle strength, muscle endurance, flexibility, and balance quality, but no significant positive changes in skeletal mass, fat free mass, percent abdominal fat(waist-hip ratio), visceral fat area, agility, total cholesterol, high density lipoprotein cholesterol, or triglycerides. Conclusion: This study showed that an exercise program has partially positive effects for middle-aged obese women. The results of this study show that exercise at community health centers should continue for middle-aged obese women's health.

Purpose: The purpose of this study was to identify the differences and relationships among knowledge, attitudes, skill, self-efficacy (SE), and Job satisfaction (JS) of healthcare managers (HMs) participated in the 4 kinds of continuing education. Methods: The subjects were 152 HMs. Data were analyzed by Mann-Whitney U test, Kruskal-Wallis H test, and partial correlation. Results: There were significant differences in knowledge according to the amount of healthcare management experience (HME) and the training program level (TPL); in the attitudes according to gender, age, and the TPL; in the skill according to the amount of HME and the TPL; and in SE according to gender and the TPL. There was no significant difference in JS according to general characteristics. There were significant positive correlations among knowledge, attitudes, skill, SE, and JS. Conclusion: The TPL was identified as a significant common variable that affects all variables apart from JS. According to these results, knowledge, attitudes, skill, and SE are considered as intrapersonal constructs, whereas JS is considered as an organizational construct. Therefore, in order to improve the quality of healthcare management, organizational strategy to enhance job satisfaction of HMs are recommended.

Vocal tract resonances are of paramount importance to voice sounds. Resonance frequencies determine vowel quality and the personal voice timber. The aim of this study was to make an effective diction program according to tuning formant frequencies by adjusting the vocal tract shape in professional voice users. Twelve male student singers and eleven female student singers participated in this study. The subjects repeated five simple vowels /a, e, i, o, u/ in normal speech and singing. The spoken vowels and sung vowels were measured by formant frequencies and the singer's formant frequencies using CSL and DSP Sona-Graph. Separately, Plot formants program was used to draw the vowel chart. The results were as follows. (1) Total formant frequencies of female singers were 11% higher than those of males singers in singing. (2) The F1 and F3 of sung vowels increased compared to F1 and F3 spoken vowels. However, The F2 of sung vowels decreased in comparison with F2 of spoken vowels. (3) Posterior vowel /u/ were moved anteriorly. This phenomenon seemed to be due to head voice singing training. (4) Singer's formant frequencies in student singers appeared according to the part: 2560 Hz for baritone, 2760 Hz for Tenor, 2821 Hz for Mezzo soprano and 3420 Hz for soprano.

The This study aimed to evaluate the effects of the voice therapy we operated to the patients with age-related dysphonia. Thirty four participants who were diagnosed as age-related dysphonia in laryngoscopic finding from January, 2009 to December, 2009 completed the study. The participants were aged from 60 to 82 years old with a mean age of 70.6. All participants had received the abdominal breath technique, SKHPIP with laughter, and basic vocal training with description of their problem, the length of which ranged from four sessions to twelve sessions. We executed the videostroboscopy to compare the aspect of voicing change and the perceptual assessment, voice range profile, acoustic and aerodynamic measures to identify change of voice. Participants had glottal gap due to incomplete glottic closure during voicing on the pretest. After they took the voice therapy, the glottic gap became narrow and rough and breathy voice was reduced. There were significant difference in acoustic and aerodynamic measures. Jitter, Shimmer, MFR were reduced and MPT, Psub were increased(p<.05). Participants' pitch range and intensity range were increased on the posttest performance after taking voice therapy. Especially, most of them were showed that pitch range was increased significantly in high frequency area. The results of this investigation indicate that the voice therapy using abdominal breath, SKHPIP, and exercise together is effective for the patients who have age-related dysphonia to improve their voice quality. We recommend to apply this technique to functional voice disorders who are showed glottal gap.
