Compensation services that are indispensable during large-scale public utilities projects have been gradually increasing with the recent increase in construction, but there are no systematic compensation services due to the complicated procedures and manual work. For this reason, various problems such as construction period delays due to various complaints, corruption in compensation work, and impossible to trace the history of compensation data in the past are emerging. In this paper, in order to solve this problem, in-depth interviews and questionnaires were conducted to find out the problems of each compensation status. Based on this, 3 core technologies and 10 technical needs based on ICT were selected to improve the compensation work by deriving STEEP analysis and Issue Tree. The three core technologies are big data-based decision-making and prediction technology, advanced measurement technology, and open cloud-based compensation platform technology. In order to introduce the derived technologies to the institutions in charge of compensation, the possibility of technology diffusion by project operators was suggested based on the results of the current status of informatization by institution. Based on the core technology derived from this paper, it is necessary to make a prototype that can be advanced in compensation work and apply it to each institution and analyze the effect.

As home network is increasing to use, home network industry is developing too. Also, it is to be a popular subject in the network's topics. In this reasons, home network become a important thing because home gateway function is working between access network and home network. In the home network, it relates on the personal computer, home pad, and digital television. But, home gateway is not prepared standard point about techniques. Therefore, many kind of technique want to try for developing of home gateway's functions. Usually, we use ID/PASSWORD method in network control system. But, we found a lot of problems about classical network system while we experienced Jan/25 big trouble. We are considering about that home network system are using same network net. Therefore, seriously we have to check about security and safety at the home network's environment. This report focus on the home network's environment to control for using and efficiency and then it wants to find ways to protect from the internal and external attacks. Existing ID/PASSWORD method it used a electronic signature and the security against the approach from of external watch, the MIB structure of role base and the security of the Home network which leads the authority control which is safe even from the Home network inside it strengthened it used compared to it proposed.

As XML becomes popular as the way of presenting information on the web, how to secure XML data becomes an important issue. So far study on XML security has focused on security of data communications by using digital sign or encryption technology. But, it now requires not just to communicate secure XML data on communication but also to manage query process to access XML data since XML data becomes more complicated and bigger. We can manage XML data queries by access control technique. Right now current XML data access control only deals with read operation. This approach has no option to process update XML queries. In this paper, we present XML access control model and technique that can support both read and update operations. In this paper, we will propose the operation for XML document update. Also, We will define action type as a new concept to manage authorization information and process update queries. It results in both minimizing access control steps and reducing memory cost. In addition, we can filter queries that have no access rights at the XML data, which it can reduce unnecessary tasks for processing unauthorized query. As a result of the performance evaluation, we show our access control model is proved to be better than other access control model in update query. But it has a little overhead to decide action type in select query.

Purpose: The purpose of this study was to evaluate a community-based cancer patient management program (CBPCMP) which was collaborated between a hospice center and public health centers. Methods: The CBPCMP proceeded on four steps; 1) Signing agreements with three public health centers, 2) Enrolling the domiciliary terminal cancer patients, 3) Providing home hospice service, and 4) Inquiring patient's level of satisfaction. From February 1 to December 31 in 2009, 43 terminal cancer patients were referred and provided with home hospice service. The hospice team made a total of 605 visits. Medical records for each visit and data from satisfaction surveys were analyzed. Results: 76.7% of patients were older than 60 years, and 90.7% of the patients were alert. The level of functional status for 76.7% of patients rated as lower than ECOG grade 1. 62.8% of the patients or their caregivers signed hospice service agreements. On the initial evaluation, the most frequent reasons for referral were general weakness (86.0%), followed by anorexia (72.1%). Nurses visited the patients' most frequently (371 visits), followed by volunteers (216 visits). Nurses provided emotional support and health promotion counseling on 95.1% and 22.9% of visits, respectively. The mean satisfaction score rated by patients and their family was 4.45 out of 5. Conclusion: This study tested CBPCMP in collaboration with hospice centers and public health centers. CBPCMP showed a possibility to improve the quality of end of life care. To insure the quality care, however, the guidelines for home hospice service should be developed.

In Korea, there are four institutions related to atmospheric science: the university's atmospheric science-related department, the Korea Meteorological Administration (KMA), the ROK Air Force Weather Group, and the Meteorological Industry Association. These four institutions have developed while maintaining a deep cooperative relationship with the Korea Meteorological Society (KMS) for the past 60 years. At the university, 6,986 bachelors, 1,595 masters, and 505 doctors, who are experts in meteorology and climate, have been accredited by 2022 at 7 universities related to atmospheric science. The KMA is carrying out national meteorological tasks to protect people's lives and property and foster the meteorological industry. The ROK Air Force Weather Group is in charge of military meteorological work, and is building an artificial intelligence and space weather support system through cooperation with universities, the KMA, and the KMS. Although the Meteorological Industry Association has a short history, its members, sales, and the number of employees are steadily increasing. The KMS greatly contributed to raising the national meteorological service to the level of advanced countries by supporting the development of universities, the KMA, the Air Force Meteorological Agency, and the Meteorological Industry Association.

Experiments were conducted to find out the landscape effects and green manure production at the same time in farmland. Cornflower was grown in different soil texture with sand, sandy loam, loam, clay loam, and was sowing with autumn and spring respectively. The overwintering rate of cornflower was at 58.7% in average, and the treatment at sand soil showed 62.1% that was highest among other soils, which cornflower is possible to winter landscape crop. After flowering of cornflower, the contents of total nitrogen (T-N) and total carbon (T-C) in plant were 15.0 and $409.2g\;kg^{-1}$, respectively, and the carbon-nitrogen ratio (C/N) was 28.6. The yield of cornflower biomass, which will be returned to soil as green manure, recorded $1,210{\sim}3,920kg\;ha^{-1}$ at the spring seeding higher than the autumn seeding as $1,540{\sim}3,170kg\;ha^{-1}$, and the biomass treated by soil texture were showed that the treatments at the clay loam had been the largest yields both spring and autumn seeding among at other treatment of soil. The heights of cornflower regardless of soil treatments were 52.8 to 73.6 cm at the autumn seeding and 35.5 to 79.2 cm at the spring seeding although it was more significant variation at the soil textures than the seeding periods. The flowering periods of cornflower ranged from $17^{th}$ to $20^{th}$ in May at the autumn seeding and from $19^{th}$ to $20^{th}$ in June at the spring seeding, which was faster 30 days approximately at the autumn seeding than the spring seeding. In a view of the cornflower application as green manure after flowering, the autumn seeding, when considered to combine with following crops, was more suitable and various than the spring seeding, even though the yield at spring seeding was higher than one at autumn seeding.

Agriculture is strongly influenced by climate change such as increased temperature and carbon dioxide ($CO_2$). This study describes the effects of climate change elevated $CO_2$, temperature, and relative drought on growth responses and yield in potato (Solanum tuberosum L.). The assessment was conducted for spring seasons in Soil-Plant-Atmosphere Research (SPAR) chamber at National Institute of Crop Science (NICS). Potatoes exhibit a positive response to $CO_2$ enrichment but water stress primarily reduces potato canopy and tuber yield. Elevated $CO_2$ and temperature increased both dry weight and tuber yield. Elevated $CO_2$ and temperature influenced SPAR 2 plants to a larger, and tuber increased yield up to 28% of than in SPAR 1(30-year average temperature at 450 ppm of $CO_2$). Our study findings indicate that tuber yield increase in potato under high $CO_2$ concentration was due to an increase in the size of individual tubers rather than in the number of the tubers per plant. On other hand, SPAR 3(30-year average temperature $+2.8^{\circ}C$ at 700 ppm of $CO_2$ under water stress) was lower than SPAR 2(30-year average temperature $+2.8^{\circ}C$ at 700 ppm of $CO_2$) nearly 56% of tuber yield due to drought. The results confirm potato drought sensitivity in terms of yield response. The experiment also showed that, in the conditions of climate change, climate change scenarios that improve cropping systems with potato.

In terms of the story told, we see that Oh! Soojung(Virgin Stripped Bare by Her Bachelors) is a film of the ideololgy of masculinity. However, from the point of view of the manner of presenting story, Oh! Soojung is a film that aims to devalue this ideology. How will it be possible? This is the principle of the irony that the speaker, by saying P, wants to make Q listen that devalues and contradicts P. Our study is tempted to explain the process of interpreting the irony in the film. The ideology of the film occurs when the presupposed contents have become the subject. For example Cendrion who tells a story of a girl married to a prince presupposes that the girl, Cendrion, is obedient. The subject of this story is that the presupposition: /the girls who want to be happy must be obedient/, which represents the ideology of masculinity. Presupposed content thus imposes on the public a collective and conservative value, as its enunciator belongs to the collective voice. Since ironisation occurs when the utterance itself is annulled, one must also deny or cancel the story told of Oh! Soojng: /Jeahun who is rich and Soojung who is obedient and virgin have become lovers/. Since there is no semantic mark within the utterance, irony is a voice that comes from without; this is how we understand irony in a purely pragmatic way. The outer voices are two things: the way to build the story: question of focusing, ocularization and auricularization, and the way to present the story: question the order, the frequency or the plot. Our study is focused on the question of frequency at Oh! Soojung which has a repetition structure in which the memory of Jeahun and that of Soojung are represented one after the other. Since the memories of two characters are not identical, the repetition is accompanied by differences. The differences at first allow the public to build their own story from the di?g?se of the film and then make the audience fall into confusion where we can not be certain of what we see and know in the di?g?se of the film, and finally make their knowledge questionable. About repetition, so that it can have validity in terms of the informativeness of the utterance, it must deny the existence of the previous repetition. This is how repetition cancels itself and consequently the utterance. We see that the irony of Oh! Soojung occurs by repetition with differences that cancels the story of the film.
