The purpose of this study is to investigate the relations between Wives' marital satisfaction and Divorce attitude as a basis building in marital stability . A measurement tools used for this study are marital satisfaction scale, which was adapted and reproducted from Dyadic Adjustment Scale(DAS) developed by Spanier and Divorce attitude Scale, which was developed by researcher refer to preceding study connected with a cause of divorce. The subjects were 354 married women dwelling in Seoul. Statistical methods such as frequency, percentile. mean , standard deviation, one way ANOVA, and Pearson Correlation were used for data analysis. The results of this study are as follows; 1) there is the tendency to high marital satisfaction group rather more than low marital satisfaction group and to permissional attitude group rather more than negative attitude group about divorce attitude. 2) There was difference in marital satisfaction by number of children, wives's educational level, parents marriage happiness. While, there was no difference in marital satisfaction by length of marriage, family income, wives employments status, marriage pattern. 3) There was partially difference in wives' attitude toward divorce by wives educational level, family income. Both there was no difference in wives attitude toward divorce by the other factors. 4) wives' attitude toward divorce correlates with marital satisfaction. The correlation coefficients is 283 significantly of .001 level. The more satisfaction wife feels about her own matrimony. the more negative a attitude she has toward divorce. This menas that attitude toward divorce depends upon their matrimony. 5) The four type of marital stability are as follows; high marital stability type, high subjective unstability type, high objective unstability type, high marital unstability type.

In recent years, data transmission using power lines has been much highlighted. Power line is known to be cost-effective communication medium because the entire cable infrastructure has been already established and it is entirely connected with any home. Recently, the target of researches is to communicate data reliably over power lines at the speed of at least 1Mbits/s over the frequency range from 1MHz to 10MHz. OFDM communication system has been used for the high speed data transmission. Next, the conventional and adaptive OFDM systems for high speed data transmission over power line channel are investigated. The performance of AOFDM(adaptive OFDM) over the frequency selective channel with impulsive and narrow-band noise are studied to be a nice solution for high speed data transmission over power lines. The simulation results show that data the rates of the AOFDM are improved about 47% more than the ones of the conventional OFDM over the frequency response of case 4. In the results, the data rate has been much improved by the proposed adaptive algorithm in the frequency selective channel.

Background: In Korea, there is low awareness of the respiratory health problems caused by the use of humidifiers, leading to a lack of governmental measures. Objectives: The objectives of this study were to review cases of varying degrees of humidifier lung and fever in connection with the use of humidifiers and to summarize the probable environmental agents causing these cases. Methods: We searched all articles reporting on humidifier lung, humidifier fever, and humidifier diseases caused by the use of a humidifier both at home and in the workplace. Results: We summarized a number of cases of varying degrees of respiratory diseases resulting from inhalation of water mist of humidifiers containing various species of bacteria and fungi and their toxins. Type of respiratory disease connected with humidifier lung includes interstitial pneumonitis, hypersensitivity pneumonitis, fever and several respiratory symptoms. Non-tuberculous mycobacteria (NTM), Actinomycetes, endotoxins and contaminated humidifier water were the most commonly suspected probable environmental agents causing humidifier lung. In Korea, the use of humidifier biocide is suspected as a likely cause of fatal lung injury including death and lung transplantation. Conclusion: Governmental policy should be devised and measures including a national surveillance system should be taken to prevent humidifier lung caused by the use of humidifiers.

Structure-borne noise and vibration is one of the main complaints of home appliances such as refrigerators, washing machines, air conditioners, etc. There have been many efforts to reduce the emitting noise and vibration. Mostly the efforts have been concentrated to optimize the mounts shape and its material properties realizing that the vibration power is mainly transmitted to the structure via mounts. It is known that softer mounts have the better vibration isolation effect. But mounts have another important function in addition to the vibration isolation. That is to support the motor and compressor safely. Thus mounts should be stiff enough to resist the supporting items. But the two properties, stiff and soft, are contradict each other. So the designer should compromise the two complicity properties properly in between. Noticing that, motors and compressors themselves are very quite until they are connected to the base structure via mounts, wire connecting idea was proposed in this work. Instead of using conventional mounts, as shown in Fig 4, compressor was mounted using six wires as shown in Fig 5. Since wire is very flexible in bending but stiff in tension, we can realize the ideal mount design requirements, stiff enough to support and soft enough to isolate vibration power. The suggesting idea was tested with an air conditioner outdoor unit.
