In case of working for the construction of blocks of any ship in a floating dry dock, there may exist deflection in the pontoon deck of the floating dock due to the ballast loading and the self weight of the ship and the floating dock. This paper is on the development of the measuring system and the GUI program to show the real time variation of the deflections at even-spaced positions by several pressure gages and the calculated inclination of the floating dock. The measured and calculated data produced by this developed system could be used to prepare the protection plan on site like ballast adjustment to ensure the safety of working during the floating dock operation.

The purpose of this study was to examine the social support network for divorced single mother families. The data were gathered through in-depth interviews with seven divorced single mothers who had at least one school-age child. Qualitative analysis of data showed that divorced single mothers evaluated themselves based on other people's perception. There were mainly three different kinds of self-images, which were “a competent divorced woman,” “a bad child to my parents,” and “a socially weak person.” We also found that there were two factors that influenced the everyday lives of single mothers: all of them .;offered hardships in living as a divorced woman with children, and they also had to deal with the weakened solidarity with family of origin, relatives, and neighbors. Single mothers shared common problems yet their lifestyles and adjustment strategies were diverse. Therefore, diverse social welfare policies for education and counseling for single mothers are urgently needed to support and empower divorced single mothers.

The objective of this research was to examine the relationship between food habits and personality. Two kinds of questionaries were distributed to 130 American college students. The data showed high relationship between personality and food habits. Poor diet group showed lower personality scores in personal adjustment, Affiliation, and nurturance while the scores in lability and succorance were higher than better diet group. A Considerable correalationship between eating preferences and personality was found. Vegetarian had higher scores in self - confidence, achievement, endurance, and autonomy while meat group were more dominant more aggressive and more changeable. Most of sweet food group were obese and had higher personality scores in abasement and deference.

In this paper, a wide-range microphone system for lectures using dual 3D sensors is proposed. A previous work using a single sensor had lowering the detecting threshold to support wide-area. However it was found that an error occurred when lecturer wears clothes with low reflectivity or has small body size. When multiple sensors are used to expand the coverage it could be cause various problems. Each sensor could show different distance to the same target. We derive the rotation angle and and compensate for lecturing microphone system using sensors on the line. The proposed method shows a little improvement in performance by about 1dB compared to the previous works but the performance is uniform in all areas regardless of reflectivity.

Recently, elevator inspection and self-examination were strengthened through the revision of the Elevator Safety Management Act, but there have been no significant reduction in serious accidents and major failures. Therefore, the government intends to lay the foundation for reflecting the safety quality rating system, which adjusts the elevator inspection cycle, as a policy to induce safety management of preemptive and active management entities. This study systematically reviewed and classified the safety quality rating system for elevator inspection cycle adjustment in previous studies, collected expert opinions, and reconstructed the key items into realistic evaluation items, and evaluated and scored the relative importance of each factor through the AHP technique.

A reinforcement learning framework is proposed for the control problem of outlet steam pressure of the once-through steam generator(OTSG) in this paper. The double-layer controller using Proximal Policy Optimization(PPO) algorithm is applied in the control structure of the OTSG. The PPO algorithm can train the neural networks continuously according to the process of interaction with the environment and then the trained controller can realize better control for the OTSG. Meanwhile, reinforcement learning has the characteristic of difficult application in real-world objects, this paper proposes an innovative pretraining method to solve this problem. The difficulty in the application of reinforcement learning lies in training. The optimal strategy of each step is summed up through trial and error, and the training cost is very high. In this paper, the LSTM model is adopted as the training environment for pretraining, which saves training time and improves efficiency. The experimental results show that this method can realize the self-adjustment of control parameters under various working conditions, and the control effect has the advantages of small overshoot, fast stabilization speed, and strong adaptive ability.

The purpose of this study was to investigate the effects of individual psychology, family environment and social environment factors on adolescents' behavior problems. The subject of this study were 500 middle school students who reside in Incheon, Geonggi-Do and 483 self reported questionnaires were used for final analysis. The findings of this study suggested that there was no significant difference between male and female adolescents in externalizing behavior problems. However, it was found that female adolescents experienced more internalizing behavior problems than male adolescents. Secondly, low levels of self-control and more contact with delinquents. were associated with more externalizing behavior problems for male and female adolescents. Self-esteem, self-control, marital conflict and contact with delinquents were related to more internalizing behavior problems for male adolescents. In addition, self-esteem, parenting behavior and contact with delinquents affected female's internalizing behavior problems.

In this paper, we propose a self-organized frequency allocation scheme for femto-cell deployment to avoid intercell interference, thereby reducing cell-registration failure. The proposed scheme follows two steps which if necessary manipulate frequency-band reallocation of existing femto-cells to accomodate newly incoming femto-cells. In the first step named "initial frequency allocation", each femto-cell collects neighboring femto-cells' frequency usage state by listening the broadcasting channels, and then selects one of interference-free frequency-bands. If no inference-free band is available, the second step named "frequency adjustment" starts, where frequency-band reallocation is properly performed from the aspect of overall performance improvement. Numerical results shows that the proposed scheme outperforms the best SINR scheme, which has been practically applied to femto-cell deployment, in terms of cell-registration failure probability and system overhead.

The following results were obtained after data adjustment and analysis of a study consisting of self-writing, of oral check-ups and questionnaires of 356 students of the O middle school in Suwon in June of 2000. The purpose of this study was to discover the effects of the dental health types of middle school students on dental caries and to understand the specific teeth of dental health types due to educational experience. Based on such data, we want to develop a desirable educational program for middle school dental heath. 1. The DMFT index was higher in females (0.75+4.39) than males(4.99+3.67), so there was a significant difference(p=0.000) 2. The DMFT index increased from the ages of 12 (4.69+3.90). 13 (5.69+3.67), 14 (6.18+4.39) and 15(6.98+4.08) and were significantly different (p=0.011). 3. There was no difference in the DMFT index regarding the method of brushing, educational experience for dental health, oral hygiene index and plaque index in dental health types. Yet, the more snack-eating increased the higher the DMFT index increased; thus, there was found a significant difference (p=0.0006). The more fluoride use increased, the lower the DMFT index; thus, there was a significant difference (p=0.048). As for the self-awareness index of dental health, the ones who answered positively had a DMFT index of 2.14+ 1.83 and those who answered negatively had a DMFT index of 7.00+3.94; thus, there was a significant difference (p=0.000). 4. For those who had had educational experience in dental health, a rolling method was used in brushing, and the frequency of fluoride use was high; the self-awareness index of dental health was high as well.
