The purpose of this study was to investigate the effects of self-esteem and gender role attitudes on youth's psychological well-being. The subjects of this research were 408 young men and women. All respondents answered by self-report questionnaire. The data were analyzed with descriptive statistics, t-tests, Pearson's correlations, and multiple regressions. The major results of this study were as follows: (a) Self-esteem and psychological well-being of young men and women were high. (b) There were changes toward the non-traditional direction in gender role attitudes of the youth. The young women exhibited more non-traditional gender role attitudes than the young men. (c) Self-esteem and family socioeconomic status showed positive influences on the psychological well-being of youth. However, gender role attitudes were not associated with youth psychological well-being.

In this work, first, a multiuser detection (MUD) algorithm based on component-level soft interference cancellation and linear minimum mean square error (CLSIC-LMMSE) is proposed, which can enhance the bit error ratio (BER) performance of the traditional SIC-LMMSE-based MUD by mitigating error propagation. Second, for non-binary low density parity check (NB-LDPC) coded high-order modulation systems, when the proposed algorithm is integrated with partial mapping, the receiver with iterative detection and decoding (IDD) achieves not only better BER performance but also significantly computational complexity reduction over the traditional SIC-LMMSE-based IDD scheme. Extrinsic information transfer chart (EXIT) analysis and numerical simulations are both used to support the conclusions.

In this paper, we proposes the steps adopted to construct the neural network model for GMAW welds. Conventional, automated process generally involves sophisticated sensing and control techniques applied to various processing parameters. Welding parameters are influenced by numerous factors, such as welding current, arc voltage, torch travel speed, electrode condition and shielding gas type and flow rate etc. In traditional work, the structural mathematical models have been used to represent this relationship. Contrary to the traditional model method, neural network models are based on non-parametric modeling techniques. For the welding process modeling, the non-linearity at well as the coupled input characteristics makes it apparent that the neural network is probably the most suitable candidate for this task. Finally, a suitable proposal to improve the construction of the model has also been presented in the paper.

This paper deals with effectiveness of Object-Oriented Modeling and Design(OOMD) through GroupSystems V which is a typical groupware or group decision support system(GDSS) to aid group work. Objective and subjective evaluations between traditional non-GDSS face-to-face group and GDSS-supported group have been performed in terms of modeling accuracy and subjective ratings, respectively. Experimental results indicate that the GDSS group shows much better performance than the traditional group in the realm of OOMD. In particular, when a modeling task is not simple or not structured, the former outperforms the latter. Based on the questionaire, the GDSS group feel more equal status and have less dominant voices than do the non-GDSS group. These facts show that GDSS can be used effectively for OOMD under Korean cultures.

Two decision feedback equalizer structures employing recurrent neural network (RNN) used for non-linear channels with severe intersymbol interference (ISI) and non-linear distortion are proposed in this paper, which skillfully put the traditional decision feedback structure for linear channels equalization into RNN, replace decision feedback signal with training signal in the learning process and adaptively adjust the learning step. Simulative results of the first type of two new equalizer structures have shown that it has better equalization performances than traditional recurrent neural network equalizer (RNNE) under the same condition.

Innovation has become a key distinct feature of modern industrial society. It is generally recognized that new knowledge and technology are one of the most important sources of innovation. However, because of their limited resources, firms can not pursue all the promising new knowledge and technology that have possibilities to be developed into critical innovation. In this article, using the stakeholder theory, we try to establish a new conceptual model that can be used for understanding knowledge creation and innovation in society. In a society, there exist diverse socio-economic groups that have conflicting values and interests. Our stakeholder theory perspective on innovation claims that innovation can occur only when new solutions can satisfy their idiosyncratic stakeholder' values and interests better than current existing solutions. From the viewpoint of stakeholder innovation theory, there could be three different types of innovation: value improvement innovation, non-traditional value Innovation, and innovation for non-traditional stakeholder.

Psoriasis is a chronic disease that has no definitive cure. In this review study, the main sources of Persian Medicine (PM) such as the Canon of Medicine (by Avicenna) and Al-Havi (by Rhazes) were assessed to identify non-pharmacological treatments for psoriasis. Several treatments that are recommended for this disease include nutritional advice, lifestyle modifications, and manipulation therapy such as wet cupping (Hijamah), leech therapy, and phlebotomy (Fasd). These recommendations may help to prevent recurrence and be useful in improving psoriasis. The efficacy of PM recommendations to improve psoriasis should be evaluated in future studies.

Traditional Korean Medicine and Taoism think of the importance of a life nurturing for one's health and longevity. However, for a life nurturing, Traditional Korean Medicine aims at a person living up to one's natural life span. Taoism lays importance on ascending up to the sky to be a Taoist hermit with supernatural powers. Therefore, they both differ in the pursuit of their goals and their methods in doing respectively. In this study we have shown similarities and differences in the meaning and ways to practice su-seung-hwa-gang (body water rising and heat falling) which Traditional Korean Medicine and Taoism regard highly as a means of the practice of a life nurturing. Su-seung-hwa-gang is a concept that both Traditional Korean Medicine and Taoism set a high value on and at the same time it is a concrete method of a life nurturing demonstrating the possibility of 'non-disease treatment' through the active efforts of Traditional Korean Medicine.

Objectives The present study examined the recent domestic and international trends of non-surgical treatment of lumbar spinal stenosis (LSS). Methods The studies on non-surgical treatment of LSS were investigated via searching Korean web databases and PubMed. As a result, 39 studies were analyzed according to the authors, the types of study, the relationship to surgical treatment and the method of treatment. Results The first authors' occupations were identified as 17 doctors, 12 Korean medicine doctors, six physiotherapists, three chiropractic doctors and one doctor of science. The most common type of study in Korea was the case report and most of the studies were retrospective. Overseas, there were many prospective or experimental studies including randomized controlled trials (RCT). In Korea, non-surgical treatment was performed independently of surgical treatment in most cases. Among non-surgical treatments, the most researched treatment was traditional Korean medicine (TKM), followed by injection therapy, exercise therapy, and physical therapy. Conclusions Through this review, we can determine the effectiveness of TKM and its research direction. TKM should be studied experimentally including RCT and it should be conducted not only on acupuncture, but also on other treatment methods such as acupotomy, chuna, and herbal medicine. It is also necessary to conduct studies on TKM before and after surgery to compare the effects of surgery and TKM together, as well the effects on non-surgical treatments.

In this paper, a new type of precast perforated concrete block is presented to be used in the construction of a step seawall. The overtopping rate of the perforated step seawall is lower than that of the traditional non-perforated step seawall. In construction stage, the cost of total construction of the perforated block is cheaper than that of traditional block. The new type of perforated block may be used as an alternative for shore protection facility.
