The purpose of this study was investigating the managers' consciousness on the interior landscape in coffee shop, the actual measurement of the space size and greenary spaces of coffee shop for grasping the actual condition of interior landscape. The coffee shop was made and object of this research was 100 cases in the center of Taegu city. The major results of actual measurement of the ratio greenary and spaces are as follows; 1. The ratio greenary spaces in the indoor plants was account for 2.06% of the coffee shop area. 2. The managers recognized that the spaces area of the interior plantscape were narrow comparison with whole spaces area about the interior landscape. 3. A major arrangement type of the interior landscape was the dispersion type. 4. A major plants used for the interior landscape were foliage plants and also most of managers prefered foliage plant. 5.Generally, managers were high interested in the interior landscape but the experience knowledge and investment in the interior landscape were not sufficient.

생산입지의 결정으로 인한 투자, 생산 및 마케팅에 이르기까지 사업의 성과에 미치는 영향은 장기간 지속되기 때문에 합리적인 의사결정이 매우 중요하다. 특히 우리가 잘 알지 못하는 지역에서의 생산입지는 더욱 체계적이고 합리적인 방법을 적용할 필요가 있다. 본 실증연구의 대상 지역인 중국은 2050부터 미국을 앞지르는 세계최대의 경제대국을 표방하고 있는 상황임을 감안할 때, 수출의존도가 매우 높은 한국으로서는 대중국 직접 투자에 대한 연구가 매우 필요하다고 볼 수 있다. 본 논문에서는 생산입지선정에 대한 선행연구에서 중요요인으로 고려된 바 있는 요인들을 정리하고, 한국 및 중국의 기업인들 및 전문가들에 의한 브레인스토밍(brain storming)방식의 설문을 통해서 평가 항목 대상들을 선정하였다. 생산입지 결정을 비롯한 다양한 분야에서 활용되고 있는 계층분석과정(AHP: Analytic Hierarchy Process)을 이용하여 양국 기업인들 간 생산입지선정 시 고려하는 요인들에 대한 중요도 인식에 차이가 있는지 실증적으로 규명하기 위해서 중국의 상해 및 심양 지역을 대상으로 실증적인 연구를 하였다.

Leaf color and plant vigor are key indicators of crop health. These visual plant attributes are frequently used by greenhouse managers, producers, and consultants to make water, nutrient, and disease management decisions. Remote sensing techniques can quickly quantify soil and plant attributes, but it requires humans to translate such data into meaningful information. Over time, scientists have used reflectance data from individual wavebands to develop a series of indices that attempt to quantify things like soil organic matter content, leaf chlorophyll concentration, leaf area index, vegetative cover, amount of living biomass, and grain yield. The recent introduction of active sensors that function independent of natural light has greatly expanded the capabilities of scientists and managers to obtain useful information. Characteristics and limitations of active sensors need to be understood to optimize their use for making improved management decisions. Pot experiments involving sand culture were conducted in 2003 and 2004 in a green house to evaluate corn and red pepper biomass. The rNDVI, gNDVI and aNDVI by ground-based remote sensors were used for evaluation of corn and red pepper biomass. The result obtained from the case study was shown that ground remote sensing as a non-destructive real-time assessment of plant nitrogen status was thought to be a useful tool for in season crop nitrogen management providing both spatial and temporal information.

Cybrid virtual plant concept is defined as a cyber plant mimicking a physical plant by using plant engineering data and sensor data coming from sensors attached to facilities of the physical plant. Cybrid virtual plant is a new concept for plant industry so that plant managers and operators' requirements need to be captured for systematic application of the concept to the plant industry. The paper proposed an architecture of the cybrid virtual plant, and provided requirement analysis results for a specific plant company. A database, named smart-cube repository, for the proposed cybrid virtual plant is also proposed and its conceptual data structure is described.

K-Maryblyt has been developed for the effective control of secondary fire blight infections on blossoms and the elimination of primary inoculum sources from cankers and newly emerged shoots early in the season for both apple and pear trees. This model facilitates the precise determination of the blossom infection timing and identification of primary inoculum sources, akin to Maryblyt, predicting flower infections and the appearance of symptoms on various plant parts, including cankers, blossoms, and shoots. Nevertheless, K-Maryblyt has undergone significant improvements: Integration of Phenology Models for both apple and pear trees, Adoption of observed or predicted hourly temperatures for Epiphytic Infection Potential (EIP) calculation, incorporation of adjusted equations resulting in reduced mean error with 10.08 degree-hours (DH) for apple and 9.28 DH for pear, introduction of a relative humidity variable for pear EIP calculation, and adaptation of modified degree-day calculation methods for expected symptoms. Since the transition to a model-based control policy in 2022, the system has disseminated 158,440 messages related to blossom control and symptom prediction to farmers and professional managers in its inaugural year. Furthermore, the system has been refined to include control messages that account for the mechanism of action of pesticides distributed to farmers in specific counties, considering flower opening conditions and weather suitability for spraying. Operating as a pivotal module within the Fire Blight Forecasting Information System (FBcastS), K-Maryblyt plays a crucial role in providing essential fire blight information to farmers, professional managers, and policymakers.

Most of chemical plant are using toxic and dangerous materials, inflammable and poisonous. There are many accidental dangers by escaping of fire, explosive and poisonous materials in case of high temperature and pressure. The accidents lead to taking employer's and local people's life and environmental contamination. Therefore, 27 small-medium chemical plant, which size is 30 ∼ 200 employees out of safety management agent ill the area of A was selected in this study. The problems of safety management and several countermeasures at the chemical plants was indicated through the analyzed data. Prior to this analysis, top managers' concerns, equipment maintenance for the safety management are needed. For the future, calamity prevention countermeasures by industrial disaster analysis are needed and active safety management programs are investigated for the industrial disaster prevention and productivity enhancement at the chemical plant.

This paper presented a actual conditions on a false-tripping of ELB(Earth Leakage Breakers) and an assessment of the harmonics due to non-linear electronic equipment such as personal computers, rectifier, electric furnace and test equipments in plant installations. Actual conditions on a failure of ELB were surveyed and analyzed by making up a question to safety managers of plant installations. Also, power quality measurements such as harmonic currents, voltage and current waveform and current imbalance were made at various plant installations where nuisance tripping of ELB is often occurred. The results of this study can be used in making decisions regarding cause of ELB trip and operating and tripping characteristics test of ELB when subjected to distorted current waveform.

The goal of this study was to investigate some significant factors to influence level of safety at plant construction field and analyze degree of risk by work classification. Currently, there are lots of construction fields for the nuclear power plant for electricity generation, and our government also planned constructing more nuclear power plant in near future. However, much of the safety literature neglected the degree of risk factors on the plant construction field. Safety managers participated in the brainstorming session for drawing decision criteria of the degree of risk (i.e., significant factors). Then, they were asked to answer a structured questionnaire which was developed for drawing most important factors. Finally, the analytic hierarchy process (AHP) was used to analyze level of risk by work classification. The following results were obtained. First, total twelve factors judging degree of risk were found in the brainstorming session. Second, the questionnaire showed four significant factors, including number of workers, working environments, skill of craft and accident experience. Third, the results of AHP showed Architecture work is the most dangerous work among 6 work types. The results could be used to reduce degree of risk in construction field of the nuclear power plant.
