Nutrition surveillance can sometimes be a powerful tool for raising awareness of nutrition problems at national and community levels and for promoting improved policies and programs to improve nutrition. Whereas many countries have been collected nutrition surveillance data for several years, the experience is often discouraging in terms of converting this data into information deemed useful by decision-makers and in terms of demonstrating impacts on decision-making. This presentation will describe the results of multi-country review of this problem undertaken by UNICEF in 1992-1994, the revised concept of "Nutrition Informatin Strategies" that emerged from the review, and the efforts currently underway at communtiy level in upstate New York to implement this revised concept.d concept.

The purpose of this study was to analyze the impacts of consumers' demographic characteristics on their involvement in retired communities, under the assumption that consumers' involvement in retired communities would be a preceding factor of the consumers' preferences for retired communities. One of the major findings of this study was that there were statistically significant differences in the involvement in retired communities by several demographic variables such as age, gender, level of education, income, total family asset, consumer values, and pursuit of happiness. Second, such involvement was strongly correlated with consumer preferences. Third, the community management styles, such as sales and rental conditions, significantly influenced consumers' level of preference. The results from this study could provide useful information not only for understanding the residents of retired communities, buffer enhancing the welfare of residents of retired communities.

This study attempted to explore the characteristics of conflicts in marriage life, and to analyze their impacts on global marital satisfaction perceived by wives in rural areas. The survey data was gathered from 151 rural wives. The degrees of three types of conflicts were shown to be low. while in terms of the degree of seriousness, environmental, interpersonal and intrapersonal are in descending order. Especially the degree of the environmental types of conflicts were significantly different across the family life cycle. In order to analyze the relationships between the types of conflicts and the marital satisfaction, logistic regression were performed. It was found that the environmental type of conflict was negatively associated with the likelihood of satisfaction in the marriage life. On the other hand, one of the control variables, the degree of satisfaction on the husband's job, i.e., farming, was positively associated with it.

Objectives : The purpose of this study was to compare the characteristics of nursing work environments based on department type and to investigate the relationship between work environment and job satisfaction. Methods : The participants were 420 nurses from the ward, emergency room, intensive care unit, and operation room. The data were analyzed by descriptive statistics, ANOVA, Scheffe's test, and multiple regression test using the SPSS Win. 18.0 program. Results : The results were as follows: There was a significant difference in possibilities for development, meaning of work, recognition(reward), role clarity, and social community at work based on department type. The factors that influenced job satisfaction were influence, meaning of work, recognition(reward), role conflicts, and quality of leadership and these differed based on department type. Conclusions : The results of this study indicate that nursing work environments vary based on the type of hospital department. Therefore, it is necessary to develop diverse strategies for human resource management considering the type of department.

When a radial collector well is installed and operated for agricultural purposes, negative impacts may be observed over time due to the clogging of horizontal arms, such as reduced groundwater discharge and water quality deterioration. When radial collector well No. 2 was rehabilitated using the high-pressure impulse generation technique, the specific capacity and transmissivity were increased by 43.1 and 100.6%, respectively. In contrast, according to air surging, the specific capacity and transmissivity increased by 33.8 and 85.8%, respectively, compared to the initial rate before rehabilitation. During the operation of radial collector wells since construction, the time of well rehabilitation can be effectively determined by continuously monitoring the groundwater level and pumping rate of the radial collector wells, thereby preventing a decrease in productivity.

Volatile compounds (VOCs) are not only media for communication within a species but also effective tools for sender to manipulate behavior and physiology of receiver species. Although the influence of VOCs on the interactions among organisms is evident, types of VOCs and specific mechanisms through which VOCs work during such interactions are only beginning to become clear. Here, we review the fungal volatile compounds (FVOCs) and their impacts on different recipient organisms from perspective of distinct lifestyles of the filamentous fungi. Particularly, we discuss the possibility that different lifestyles are intimately associated with an ability to produce a repertoire of FVOCs in fungi. The FVOCs discussed here have been identified and analyzed as relevant signals under a range of experimental settings. However, mechanistic insight into how specific interactions are mediated by such FVOCs at the molecular levels, amidst complex community of microbes and plants, requires further testing. Experimental designs and advanced technologies that attempt to address this question will facilitate our understanding and applications of FVOCs to agriculture and ecosystem management.

To gain maximal benefit in a competitive environment, single-celled bacteria have adopted a community genetic regulatory mechanism, known as quorum sensing (QS). Many bacteria use QS signaling systems to synchronize target gene expression and coordinate biological activities among a local population. N-acylhomoserine lactones (AHLs) are one family of the well-characterized QS signals in Gram-negative bacteria, which regulate a range of important biological functions, including virulence and biofilm formation. Several groups of AHL-degradation enzymes have recently been identified in a range of living organisms, including bacteria and eukaryotes. Expression of these enzymes in AHL-dependent pathogens and transgenic plants efficiently quenches the microbial QS signaling and blocks pathogenic infections. Discovery of these novel quorum quenching enzymes has not only provided a promising means to control bacterial infections, but also presents new challenges to investigate their roles in host organisms and their potential impacts on ecosystems.

There are two main types of agricultural extension projects in Korea, the impacts and routes of each type on farm income are different. This paper empirically studies the impact of agricultural extension to farms' income, using Multi-level production function considering time lag. It is found that direct type of extension has positive effect to farms' income. Also indirect type on income is significant only when the level of education is high. Due to the characteristics of Korean agricultural structure, the technical level of farm is greatly influenced by the government's R&D investment and technology guidance. The result implies that indirect type of extension that take into account the educational level of farms should be emphasized for long-term technological advances.

Ethnic tourism is utilized by many countries to improve the economic status. Ethnic tourism in Xishuangbanna started from the 1980s and grew rapidly during the past 2 decades. Although many researchers had stressed economic and socio-cultural impacts of ethnic tourism on ethnic minority people, little was done to identify their subjectivities. This research revealed the social and economic benefits from ethnic tourism, representing the identity of ethnic minority people. This research investigated the ethnic groups' subjectivities toward ethnic tourism and identity in Xishuangbanna, Yunnan, China, using the Q-methodology. It was found that the community residents did not get much benefits regardless of the social welfare that ethnic tourism had brought about. Finally, this research also made several implications with regard to tourism management.

The rice blast disease, caused by the fungal pathogen, Magnaporthe oryzae (syn. Pyricularia oryzae), poses a significant threat to the global rice production. Understanding how this disease impacts the plant's microbial communities is crucial for gaining insights into host-pathogen interactions. In this study, we investigated the changes in communities of bacterial and fungal endophytes inhabiting different compartments in healthy and diseased plants. We found that both alpha and beta diversities of endophytic communities do not change significantly by the pathogen infection. Rather, the type of plant compartment appeared to be the main driver of endophytic community structures. Although the overall structure seemed to be consistent between healthy and diseased plants, our analysis of differentially abundant taxa revealed the specific bacterial and fungal operational taxonomic units that exhibited enrichment in the root and leaf compartments of infected plants. These findings suggest that endophyte communities are robust to the changes at the early stage of pathogen infection, and that some of endophytes enriched in infected plants might have roles in the defense against the pathogen.
