  • With the increasing influence of online media, company websites have become important communication channels between companies and customers. Companies use their websites as a marketing tool for a variety of purposes, including enhancing their image and selling products or services. Many researchers have examined the criteria, methods, and tools for website evaluation, but most have focused on usability. Prior content analyses have focused not on text content but on website components, an approach likely to produce subjective evaluations. This study attempts to objectively evaluate company websites by utilizing text mining. We analyze the usefulness of company websites by presenting visualized outputs from a business perspective, allowing practitioners to easily understand the results of the website evaluation and use them in decision making. To demonstrate our method empirically, we selected a company with a number of affiliates in Korea and analyzed the text content of their websites to assess their usefulness using natural language processing and graphics packages in R. Practitioners can easily employ our objective evaluation method, and researchers can use it to gain a new perspective on website evaluation.

  • Agricultural water occupies the largest portion of total water use in Korea, and generally researches on the development of agricultural water have been stressed on the demand of agricultural water itself. But it is unavoidable to change a policy from the development of water resources to cope with the increase of water demand to the effective management of existing water resources. Evaluation of the decrepitude of irrigation facilities and their reasonable maintenance are important for the effective supply and use of agricultural water. Therefore it is necessary to develop evaluation technique that diagnoses the current condition of irrigation canals and suggest a countermeasure to improve the found problems. 25 items in 6 classes were selected for the evaluation of irrigation canal systems, and the weighted value between the items was calculated using AHP (Analysis Hierarchy Process) method. The current condition of the irrigation facilities was evaluated from the class evaluation marks, and ranking was decided from the total marks between the projects, and finally the priority of the project for the improvement was given.

  • The basis of the economic evaluation of vaccination is the balance between the use of the resources (input) and the improvements that result from the vaccination (output). Techniques used for economic evaluation of vaccination are cost analysis, cost-minimization analysis, cost-effectiveness analysis, cost-utility analysis and cost-benefit analysis. Cost analysis seeks to characterize the costs of a given vaccination program. Cost-effective analysis is to helps policy-makers decide on the best use of allocated resources, whether cost-benefit analysis is to helps policy-makers decide on the overall allocation of resources. Cost-utility analysis is a specific form of cost-effective analysis in which outcomes are reduced to a common denominator such as the quality-adjusted life year (QALY) or disability-adjusted life year (DALY). Many economic analyses have been conducted on vaccines in the world, but there have been a little studies on economic evaluation on vaccines in Korea. This paper reviewed the methodology used to economic evaluation on vaccines and immunizations and addressed some examples of the methods.

  • This study suggested practical application of decision aid tool on re-evaluation of current buildings with a focus on a energy and economics evaluation methodology. In Europe, over forty percent of all construction activities are for retrofit. For efficient construction, various tools for re-evaluating existing buildings have been developed and are in use. Legislations of relevant laws and studies are actively initiated. In particular, EPIQR (Energy Performance Indoor environment Quality Retrofit), which was developed through the EU's Third and Fourth Framework Programs laid a foundation on a new concept-based decision aid tool for re-evaluation of existing buildings. As for actual applications, based on this, EPIQR+ was developed to be in line with a building maintenance guideline (SIA 469) and is actively applied to public buildings. This tool quantifies the degree of damages of existing buildings and suggests alternatives to users in energy (SIA 380/1) and economical perspectives. This study examined these preceding tools and suggested some trenchant approaching for more comprehensive and efficient use of re-evaluation tools in building maintenance.

  • This study was carried out to propose the functional assessment and a wise use strategy on the ecologically valuable 'village wetlands' distributed in living area in Geumsan gun, Chungnam province, Korea. The targets of the functional evaluation were 24 wetlands, selected from 123 village wetlands, where villages and agricultural lands or core ecosystems are located within living area near the wetland and wetlands with historical and cultural significance. The functional evaluation was carried out by RAM (Rapid Assessment Model) and the conservation strategies were suggested. As a result of the functional evaluation, 9 wetlands were rated 'high' (2 'absolute conservation' and 7 'conservation' strategies), 14 wetlands were rated 'medium' ('enhancement' strategies), and one wetland was rated 'low' ('restore or enhancement' strategy). In consideration of the results of the functional evaluation, interviews with village residents, and historic meaning, 6 important village wetlands were selected that require additional management strategies, such as conservation, enhancement, and restoration. 2 wetlands were from "absolute conservation" strategy and 4 wetlands derived from "conservation" and "enhancement" strategy wetlands in consideration of the ecological connectivity of wetlands, the use of surrounding land, and the function as a biological habitat. The wise use and conservation strategy was specifically proposed respectively.

  • Recently, as a countermeasure to the buoyancy of a building, the use of permanent drainage methods have been on the increase, and these provide benefits both in terms of economical feasibility and efficiency. When a permanent drainage method is applied, some underground water can drain out. Korea has been designated by PAI (Population Action International) as a water-stressed country, and the use of outflowing groundwater is required for the efficient oversight of water resources. However, the evaluation process on the practical use of underground water is currently insufficient. Therefore, the amount of outflowing groundwater put to practical use and the standard for the water quality were examined in this research, with the aim of establishing anappraisal process on the practical use of underground water drainage. In addition, standards for the assessment of the treatment process and the application cost of underground water drainage were developed. On this basis, an evaluation process on the use of outflowing groundwater was developed and applied inthe field. The application result proved that it was possible to assess the initial investment cost and the maintenance and management cost in the field, and thesecan be compared to the costs when supplied water is used, which makes it possible to apply in the field.

  • This study focused on the production and usability evaluation of smart outdoor jackets that are designed to provide convenience to middle-aged people by embedding devices for lighting and location tracing. The results were as follows. 1. Jacket power supplier was a assembled system composed of battery, charger, controller and switch. A solar cell was attached on the upper arm, and a wire type EL on the center line of a raglan sleeve along with a GPS on the left sleeve with a transparent vinyl pocket. The total weight of the jacket embedded with devices was 385-520g. 2. Operation of function, activity, acceptability, safety, convenience for device use, appearance, practical maintenance were selected based on an analysis of evaluation criteria of previous smart wear research. Criteria were narrowed to three major categories of satisfaction, appearance and maintenance. 3. Use satisfaction criterion consisted of wearable device functionality and physical, psychological use convenience. The evaluation indicated actual functionality. EL functions were especially effective and necessary. Convenience of use showed that a smart jacket was thought to be safe and the size was moderate regardless of age and gender. Outer appearance was satisfactory and respondents praised the color. The practical maintenance evaluation indicated that there was no challenge in doing the laundry since the solar battery and GPS were detachable. The practical use of smart outdoor jackets confirmed by fabric that was washable and dried quickly.

  • Most companies are achieving economic benefits by producing products in the form of bi-national products, but there are also negative consequences such as reduced brand power, so strategic bi-national product planning and branding is essential. In order to actively reflect these practical needs, this study conducted a comprehensive and easy-to-generalize evaluation of Bi-national products that has been somewhat underdeveloped in previous studies. To this end, the selection and evaluation criteria of the products to be investigated were differentiated. This is to classify the products by place of use and the purpose of use so that the majority of bi-national products can be included, and then use the combination to derive the specific products to be evaluated for bi-national products. The evaluation of the product identified the phenomenon of psychological conflict among consumers due to the country of origin discrepancy at the level of decreasing brand authenticity. The above research design is an evaluation method that can encompass bi-national products as a whole, rather than an evaluation of a specific product or product line that is mainly reported in previous studies, and it is also very easy to apply to practice because it allows us to more carefully identify changes in psychological attitudes.
