This study analysed marital comflicts, related factors, and adjustments to those conflicts described by urban Korean women. The purpose was to discover directions for resolution that would enhance the helpfulness of volunteers or prfessionals working with women in counselling settings. The investigator interviewed 20 married women, all mothers and housewives living in Seoul, attending marriage encounter programs and the Lifeline telephone counselling service. An interview schedule using six open-ended questiona guided the data colleciton which took place between May 31 and December 29, 1988. Content analysis of the data revealed, in order of reported frequency, the following areas of conflict: relationships between husband wife, relationships with children, relationships between the wife and her mother-in-Law, unsatisfied sexual needs, the husband's extra marital relationships, lack of self actualization and finacial matters. Analysis of the data suggested the following factors were related to the conflicts: reasons for marriage, traditional views about marriage and divorce including to accept a marriage arranged by the parents, the husband's traditonal attitude toward the sex role of the wife, the husband's patriarchical authoritarianism, and his attitude toward the wife;s empolyment outside the home. The women thought these conflicts severely affected their relationships within the famaily, particularly with their children. Literature suggests links with such poor parent-child-family relationships and adolescent or young people's social problems. Volunteers or professionals working with married women in counselling situation need to be conscious of the possibility of these conflict during assessment, and direct their guidance toward such conflict resolution. The researcher makes several suggestions which include the need for the husband to give emotional supports to his wife, to recognize the worth of housework, to share the work of the home, to fine ways to enhance the wife's self-actualization and to ease dreary housework routines by prviding modern appliances.

Interest in smart cities is growing; information and communication technology, urban planning, urban economy development, health, and many other areas are intertwined within smart city research and practice. The definition of smart city is evolving, and its vagueness is sometimes confusing. This review of the smart city literature tries to capture the big picture of this big idea. This review places into context work done since 2016, as earlier work is well reviewed in Albino (2015) and Cochia (2014). First is a review of the various smart city definitions. Second, an inventory of terms related to or subsumed by the smart city label are presented. Third, outcomes of indexes created to measure a city's smartness are presented. Fourth, the taxonomies used to organize the disparate content that falls under the smart city umbrella are discussed. Fifth, the most recent literature associated with six commonly recognized subgenres, namely smart economy, smart governance, smart living, smart people, smart environment, and smart mobility are reviewed. Sixth, important critiques of the smart city idea are presented.

The land treatment of sewage sludge is necessary because sewage sludge is increasing year by year. Therefore the research of sewage sludge solidification is underway as one of the land treatment methods. However, the problem with existing sewage sludge solidification is that the moisture content of sewage sludge is high and the dewaterability is low. Because of high drying cost the efficiency of energy production is low and the calorific value is insufficient. So the disposer is supplied with a filtration and caloric aid for improving dewaterability and calorific value. In this study, it is aimed to improve the fuel value of sewage sludge by confirming the feasibility of waste wood as a filtration and caloric aid. The dewaterability was measured by CST-test and the calorific value was measured by bomb calorimeter. As a result the dewaterability and calorific value are improved in all of the samples. The dewaterability was improved as the waste wood was added in the sewage sludge. By adjusting the waste wood adding rate into the sewage sludge the dewaterability and calorific value of sewage sludge will be improved. This study confirmed possibility of the waste wood used as filtration and caloric aid.

Web 3.0 is also called the "next-generation Internet" and is a new concept that started in 2018 and is attracting attention as the beginning of the "distributed Internet era". As Web 3.0 became mainstream, non-fungible tokens (NFTs) serving as content as services were distributed, and companies started to introduce NFTs in their marketing campaigns. This is because NFTs can be used to promote brands to new consumers. In this study, using Japan's 「HARTi」 NFT Art as an example, we investigate a new method using urban infrastructure and spaces, not NFTs that exist only in the Japanese art market and online. By analyzing social issues following the introduction of a new digital marketing method based on NFT Art, we will discuss issues and countermeasures in the domestic NFT Art market and present a positive outlook.

Resistivity cone penetrometer test (RCPT) can be employed at a relatively low cost for in-situ delineation of subsurface contamination. While the resistivity measurement has a potential to investigate the subsurface contamination, resistivity measurements alone will lead to some degree of ambiguity in the results. In this study, capacitance measurement was incorporated into the RCPT to overcome the ambiguity inherent in electrical resistivity measurements. This study is focused on verifying the applicability of resistivity and capacitance measurements of CPT module to provide information on subsurface contaminated by heavy metal and petroleum hydrocarbon. Laboratory model tests were performed to evaluate the sensitivity of the measured resistivity and relative capacitance on the water content and different types of contaminants. Test results show that simultaneous measurement of electrical resistivity and capacitance can give more reliable information on subsurface contamination. Electrical measurements of the CPT module showed high applicability to be used in detecting saturated soils contaminated by heavy metal and diesel plume floating above the groundwater table.

In this study, we examined the effect of high temperature of urban area on the physiological response of apple tree including the photosynthesis, shoot growth, and fruit quality of 'Fuji'/M.9 apple trees planted at Daegu urban area (DUA) and Gunwi rural area (GRA) for 2 years (2009-2010). During the apple growing season (April-October), the average air temperature of DUA was about $3.0^{\circ}C$ higher than that of GRA and the total rainfall of DUA was 130 mm more than that of GRA. During fruit enlargement stage (June-August), the number of days that recorded daily mean temperature of over $30^{\circ}C$ were ten on DUA in 2010, but there was no day when such temperature was experienced in 2009. Average air temperature of DUA during the maturation stage (September-October) was $19.8^{\circ}C$, which was $4.0^{\circ}C$ higher than that of GRA. The higher temperature of over $30^{\circ}C$ during fruit enlargement stage decreased the photosynthetic rate, shoot growth, fruit weight, and soluble solid content of 'Fuji'/M.9 apple tree. The moderate temperature of about $20^{\circ}C$ during maturation stage increased the photosynthetic rate and soluble solid content of 'Fuji'/M.9 apple tree, but decreased fruit red color. In regional comparison with GRA, photosynthetic rate of DUA was changed from lower before rainy season to higher after rainy season. Fruit weight was higher in DUA than that of GRA. However, fruit weight between DUA and GRA did not show the difference when accumulated days that recorded daily maximum temperature over $35^{\circ}C$ of DUA was increased. Compared to the GRA, soluble solid content of DUA was higher, but fruit red color of DUA was less. These results indicate that the poor red coloring is the most problematic in 'Fuji'/M.9 apple tree by global warming and urbanization.
