As the average temperature on Earth increases due to global climate change, crops are further needed to overcome this issue. Since sweet potato has high yield potential, can grow in harsh environments, and contains abundant nutrients, it is a potential substitute food in response to environmental crises. Compared to grains such as rice and barley, sweet potato has a lower glycemic load and contains various natural antioxidants, showing a variety of physiological functions. Thus, sweet potato is in the spotlight as a healthy food. Although domestic sweet potato production continued to decrease from 1990 to 2010, its production was maintained or slightly increased until 2020 due to the changes in consumers’ dietary habits that emphasize health. In this regard, steamed or roasted sweet potatoes were consumed as a snack substitute in the previous eating form. Furthermore, sweet potato starch has been used in various industries, including food. Therefore, this study intends to discuss the value of sweet potatoes as food, the production trend and cultivation method of sweet potatoes in South Korea, and the industrial application of sweet potatoes.

This study applied enneagram personality type system to improve the quality of life by efficient job placement for industrial workers. Applying the enneagram personality type system in a constantly changing business environment has a competitive edge in developing and utilizing workers' internal resources and capabilities. Each of enneagram nine type has characteristics such as core needs, motive and ability in job field, expression method and relationship. These characteristics can be used for efficient job placement of workers. In Korea, for the past 30 years when enneagram was introduced, educational programs for the public, teenagers and parents have been developed, but the professional programs for company were very poor. Therefore, educational programs development for professional business managers and workers are required.

Value creation is essential for successfully operating a firm and becomes a critical issue for realizing cross-firm competition and industrial performance distinctions. Tourism scholars have viewed tourism value-chain (TVC) as a useful tool to measure the efficiency and effectiveness of performance through controlling the impact factors in tourism products and services. However, few extant studies focus on the works of performance measurement in the tourism industry. This study applies Yilmaz and Bititci’s (2006 a, b) concept to develop novel performance measurement and value creation indicators for industrial tourism and customers through a crisp-set qualitative comparative analysis (QCA). The QCA approach considers asymmetric relationships—reporting conditions that are sufficient or necessary to cause an outcome condition. QCA allows exploring the causal-effect relationship between the variables. In-depth interview with five senior managers and five customers were conducted. The QCA results showed that industrial tourism and customer performance indicators have complex links with value creation. The main theoretical contributions of this study extends through four stages of TVC on both manufacturing and industrial tourism, developing causal-effect connections of industrial tourism, and customer performance on value creation. The study describes how proprietors and service providers promoted brand identification and firm’s reputation for achieving industrial tourism value. The findings beneficially provide practical implications for proprietors and customers for applying performance indicators once aiming to develop an appropriate marketing strategy and create industrial tourism and customer values.

In this study, the land use is analyzed by using the SWMM-LID (Low Impact Development) program to minimize the environmental damage caused by the development. In order to effectively utilize pre - development hydrological conditions, we analyzed the land use of existing industrial complex. The study areas selected were a completed industrial complex and an ongoing industrial complex in order to effectively identify the characteristics of the industrial complex and the water circulation system. Numerical simulation used SWMM-LID to enable quantitative hydrological impact assessment of penetration, storage facilities and LID planning elements. In the case of natural conditions, the infiltration amount was 16.3% and 1.5% of the total rainfall at B, C point, respectively. However, after applying the existing land use plan, the infiltration amount at point B was 12.1% and at point C was 3.9 %. In the case of point B, the amount of infiltration decreased due to the development of greenery as an impervious site. On the other hand, the amount of infiltration at point C increased as the existing industrial complex was replaced by greenery. Therefore, high infiltration amount can be secured when land use plan is redeveloped in green areas or parks in areas where the permeability coefficient is high according to the ground conditions in the complex. Two types of bio-polymer soil were developed to increase the LID effect and were tested to compare typical soil with these bio-polymer soils.

Volunteer is defined as a person who offer service for social welfare work without pay voluntarily and people who recognize the importance of volunteer activity and engage in volunteer work in government offices and non-governmental organizations. However, the disaster protection for the volunteers is still out of the law’s boundary. The volunteer in volunteer organizations, social welfare organization as well as teenage volunteer are now protected in nation through private health insurance but its coverage is limited and the guarantee level is not sufficient to protect volunteer. If volunteers cannot be protected from industrial accidents or paid proper compensation to realize their human dignity by assuring a basic right to live, it leads to serious loss personally and socially. If the volunteers are protected by occupational health and safety insurance that functions as social insurance and the industrial accident risk gets removed, it will contribute to invigorate the volunteer activities and thus, legal improvement and institutional strategy must be required so that volunteers enjoy various insurance benefits in Industrial Accident Insurance.

Unpaid family workers operate projects for business with my family is Officially, but are paid to the beneficiary of the joint cost of living in real terms or at a separate wage. In other words, as defined in employment laws that do not receive wages provide workers for the purpose of Labor Standards Act because they don't see that not be regarded as an employee. Therefore, unpaid family worker workers are excluded from the application of the statutory. Unpaid family worker are protected against the risk of an industrial accident or industrial disasters through Guarantee basic right to exist to them through appropriate compensation in the event. Safeguards to the realization of human dignity unless this is a personal level as well as social dimension in them a great loss and industrial insurance. There are subject to the need to expand to include social safety net.

Peak load rate(i.e., maximum daily flow/average daily flow) has not been considered for industrial water demand planning in Korea to date, while area unit method based on average daily flow has been applied to decide capacity of industrial water treatment plants(WTPs). Designers of industrial WTPs has assumed that peak load would not exist if operation rate of factories in industrial sites were close to 100%. However, peak load rates were calculated as 1.10~2.53 based on daily water flow from 2009 to 2014 for 9 industrial WTPs which have been operated more than 9 years(9-38 years). Furthermore, average operation rates of 9 industrial WTPs was less than 70% which means current area unit method has tendency to overestimate water demand. Therefore, it is not reasonable to consider peak load for the calculation of water demand under current area unit method application to prevent overestimation. However, for the precise future industrial water demand calculation more precise data gathering for average daily flow and consideration of peak load rate are recommended.

정삼투 공정은 에너지 소비율면에서 역삼투 공정 대비 1/10 수준이며, 고압⋅고에너지를 요하는 역삼투 공정의 대안으로 각광받고 있는 기술이다. 이러한 정삼투 공정은 저에너지 및 고효율화를 요구하는 산업분야에서 다양하게 적용 가능할 것으로 예상된다. 그 예로서, 선박 폐열을 이용한 유도 용액 회수, 산업폐수 재이용, 휴대용 비상 급수용 장치, 음식과 음료 및 의약용품 농축공정 등을 들 수 있다. 현재까지 정삼투 공정은 주로 실험실 규모에서 연구가 진행되었으며, 기술 상업화에는 아직 이르지 못한 실정이다. 국외에서는 미국, 싱가포르 및 호주 등에서 정삼투 실용화 연구가 활발하게 진행되고 있으며, 국내의 경우 FOHC 연구단에서 해당 공정의 기본 메커니즘 및 실용화에 관한 연구가 이루어지고 있다.

Zeolite membranes can be used as vapor separation membranes due to the adsorption properties of zeolite crystals. Recently, vapor separation membranes are paid attention in the petrochemical complexes by combining with distillation separation methods. Heat duty for separation can be reduced by the combination of distillation and membrane. Zeolite membranes are usually crystalized on porous ceramic substrates such as a porous alumina substrates. Here, we had paid attention to novel porous silica substrates. In this study, effects of porous silica substrates on preparation of MFI zeolite membranes were investigated to obtain high permselective membranes. Acetic acid vapor permeation tests were conducted for the typical application in the petrochemical complexes. Porous silica (pore size: 500 nm) or porous α-alumina (pore size: 700 nm) were used as ceramic substrates. The seed crystals were coated by changing the seed slurry (0.5g L-1) of pH from 2 to 12. MFI membranes were crystalized at 180 °C for 16 h. The parent gel compositions for the membranes synthesis were SiO2: TPABr: Na2O: H2O=1: 0.2: 0.04: 600 (mol/mol). Vapor permeation tests of acetic acid/water were carried out at 110 °C. N2 permeance through the membrane prepared on the silica substrate was 3.6 × 10-6 mol m-2 s-1 Pa-1, while that through the membrane prepared on the alumina substrate was only 1.4 × 10-6 mol m-2 s-1 Pa-1. The initial resistance through the alumina substrate was lower than that through the silica substrate. This shows that the effective MFI layer was thinner on the silica substrate. N2 permeances through all the membranes were similar at around 4 × 10-6 mol m-2 s-1 Pa-1. The maximum N2/SF6 permeance ratio was 79.3 through the membrane coated at pH 2. Thus, seed coating was important to obtain high gas permselective membranes. The separation factor of acetic acid through the MFI membrane was over 20. Thus, we have concluded the MFI membrane was acetic acid permselective membrane.
