  • There are many problems that occur currently in agriculture industries. The problems such as unexpected of changing weather condition, lack of labor, dry soil were some of the reasons that may cause the growth of the plants. Condition of the weather in local area is inconsistent due to the global warming effect thus affecting the production of the crops. Furthermore, the loss of farm labor to urban manufacturing jobs is also the problem in this industry. Besides, the condition for the plant like air humidity, air temperature, air quality index, and soil moisture are not being recorded automatically which is more reason for the need of implementation system to monitor the data for future research and development of agriculture industry. As of this, we aim to provide a solution by developing IoT-based platform along with the irrigation for increasing crop quality and productivity in agriculture field. We aim to develop a smart garden system environment which the system is able to auto-monitoring the humidity and temperature of surroundings, air quality and soil moisture. The system also has the capability of automating the irrigation process by analyzing the moisture of soil and the climate condition (like raining). Besides, we aim to develop user-friendly system interface to monitor the data collected from the respective sensor. We adopt an open source hardware to implementation and evaluate this research.

  • Purpose - This paper explores a new possibility of care ethics for social service. As the needs for care have been growing rapidly in various social fields, 'care' became an important concept in envisioning a welfare state. However, due to the lack of proper ethics and political stance applied to the newly arisen needs and challenges, there exist lots of confusions and difficulties. Research design, data, and methodology - Introducing the feminist ethics of care, this paper examines the relationship of care and justice in social service. As a main research perspective, this study has focused on Kittay's public ethics of care and Tronto's political ethics of care. Results - Drawing on the main research perspective, this study discusses on the necessity of a political conceptualization for an integrative care ethics. In the process, The specialty and professionality of care work as a relational labor was reconsidered. Kittay's care ethics provides a persuasive justification for social support for care workers as well as care receivers, and Tronto's ethics shows us the role of care politics for democratic citizenship. Conclusions - Tronto's ethics of care with Kittay's gives us valuable insights to envision a new public ethics for social service that takes into account both care and justice properly.

  • The purpose of this study was to examine the economic status of retired elderly households. This study especially looked for the differences in the economic status among retired elderly households and the level of subjective financial strain. The data were drawn from the data of 2000 Korean Labor and Income Panel Study (KLIPS) conducted by the Korea Labor Institute. The major findings are as follows: 1) The levels of income in the retired households were found to be lower than those of the employed elderly households, and the transfer income took the biggest portion out of 5 income types reflecting high economic dependency. 2) The levels of expenditure were found to be similar to the minimum living cost, and the food cost at home was 41.9% of the expenditure. 3) About 40% and 27.3% of households reported that they felt financial strain due to food expenditures at home and health care respectively. 4) Ninety percent of all assets were found to be real estate, reflecting the lack of asset liquidity. Further, retired elderly households were classified as 'not at all strained financially', 'moderate', 'seriously strained', and 'extremely strained' groups according to their subjective assessment. The last two groups showed the lower level of income and expenditures than the first two groups. In particular, 26.5% of retired elderly households belonged to 'extremely strained' group and showed very serious economic problems.

  • Through Information and Communication Technology (ICT), the growth of music streaming platforms has revolutionized music consumption. "Digital Shadow Work" (DSW) refers to unpaid labor in digital spaces, with some prior research on its aspects. However, a comprehensive understanding is hindered by limitations in existing studies such as a lack of universality and dynamic exploration. To address these gaps and enable a comprehensive investigation into the role of DSW within highly versatile digital applications such as digital streaming platforms, this study employs a grounded theory methodology, a qualitative approach well-suited for exploring the intricacies of DSW among users of Chinese music streaming applications over a two-month period, involving longitudinal interviews with nine participants. The study findings elucidate the dynamic nature of DSW perceptions, which fluctuate across different stages of use and change in intensity over time. This study uncovers mixed attitudes towards DSW tasks, and observes a waning enthusiasm for social features over time, prompting some users to consider switching platforms. This study highlights the importance of thoughtful and user-centric feature development to enhance user satisfaction and the understanding of DSW, providing practical design and enhancement implications for music streaming applications.

  • The purpose of this study was to find how economic structures differ among four different household groups('enough', 'so so', 'a little difficult', 'very difficult') classified by subjective evaluation on their economic conditions. The data were drawn from 2004 Korean Labor and Income Panel Study conducted by Korea Labor Institute, and $X^2$-test and F-test were utilized by SPSS for Windows 10.0. The major findings were as following. First, the economic levels of household groups of 'enough' and 'so so' showed to be higher than the average. This result implies that households tend to evaluate by themselves their economic conditions comparing to the others. Second, the deviations of average economic levels among four different household groups were relatively bigger in household economic elements of liquid asset, monthly savings and insurance than the others, and relatively smaller in household economic elements of total expenditure, especially expenditures in food at home, education, medical, communication than the others. Third, the households of 'a little difficult' and 'very difficult' showed undesirable economic structures resulting from lack of savings and insurance for their future.

  • Korean logistics industry have been focused on transportation business. However, with the expansion of the electronic commerce and on-line shopping, delivery service is now dramatically growing. Despite the expansion of logistics market, the domestic logistics industry have significant structural problems such as low productivity comparing with the advanced countries, relatively high cost and shortage of human resources and lack of professionalism of people in the industry. Logistics companies reallocate employees, use subcontractors, expand consignment and training the employees to overcome the labor shortages but it has some limits. In recognition of the importance of labor in the logistics industry, financial support and investment have increased. Logistics companies tend to hire consultants, set up logistics department or R&D center in order to establish highly productive logistics process and system so it is viewed that there will be considerable demands of human resources in the logistics industry. This study indicates implications and development direction of human resources in the logistics industry by looking into prospect and characteristic of the industry, employment status, training programs and qualification requirements.

  • Natural environmental protection system in North Korea is rarely understood mainly because of lack of information in scientific and legislative fields. Legislation is very important to achieve goal for protected areas, which are described in "Natural Protected Area Law(NPAL)". Cabinet of North Korea has authorities to lead the Central Agency for Land and Environment Conservation(CALEC). Designation and managements of natural protected areas are regarded as CALEC and local governments responsibilities. There are many differences between South and North Korea. Especially legislation system has many differences. North Korea's Labor Party is superior to the Government and Labor Party's order has at least the same authority to regulate and manage the national policy and means. With NPAL, CALEC organizes the national plan for natural protected area and regulate the activities of the Agencies for Land and Environment Conservation in the aspects of action plan, budget and other resources. For the reunification in the future, legislation system of North Korea should be understood.

  • Objectives : The study was to examine the empirical evidence concerning the effects of massage intervention for the laboring women and to investigate the effect sizes related to the characteristics of intervention. Methods : Meta analysis was performed. A total of 11 trials related to massage intervention between 2000 and 2007 were reviewed. Results : Massage intervention showed a beneficial effect on length of labor(1st stage : U=46.75, p=0.00, 2nd stage : U=6.13, p=0.01), perception of childbirth experience(U=12.57, p=0.00), intensity of uterine contraction at the active(U=6.34, p=0.01) and the transition phases(U=24.83, p=0.00), and interval of uterine contraction at the active phase(U=4.83, p=0.03). Massage decreased systolic(U=10.81, p=0.00) and diastolic blood pressure at the transition phase(U=10.60, p=0.00). However, massage had no effect on subjective and objective labor pain and anxiety. No differences were found in effectiveness of massage according to characteristics of intervention(massage material, massager, and massage site) except for anxiety(QB=4.82, p=0.03) and diastolic blood pressure at the active phase by massage site(QB=4.52, p=0.03). Conclusions :We found that massage intervention for the laboring women had an empirical evidence on improving perception of childbirth experience and shortening length of labor. These results should be interpreted with caution due to the lack of studies. More full-scale randomized clinical trials with reliable designs are recommended to further warrant the effectiveness of massage.

  • This study was conducted to survey and diagnose operation status of the agricultural machinery rental service, analyse and compare operational efficiency among 82 city and county ATDEC (agricultural technology development and extension center) using the DEA (Data Envelopment Analysis) method, and recommend future direction, for improvement of the business. Input variables were invested budget and labor, and output variable was rental return. Percentages of return to investment on the rental service were calculated as 68.3% and 63.9% when analyzed with CCR (Charnes, Cooper and Rhodes) and BCC (Banker, Charnes and Cooper) models, respectively, indicating inefficiency of the service operation. Increase of rental charge would increase efficiency by 63.9~68.3% depending on models, and decrease of financial and labor investment would improve the efficiency by about 11.3%. Technical efficiency would be more important than scale efficiency, therefore adjustment of over-invested budget and labor needed to be made together with increase of rental charge to improve the operation. Among the ATDECs providing the rental service, 6 (7.3%), 43 (52.4%), and 33 (40.2%) were in state of CRS (constant return to scale), IRS (increasing return to scale), and DRS (decreasing return to scale), respectively. These indicated public aspects of the rental system, over-investment, lack of output component for input component, meaning that scale income would be increased by qualitative expand of rental charge. Efficiency analysis of the rental system by region showed that efficient ATDECs to be benchmarked by others were in the order of DMU-70, DMU-54, DMU-29, DMU-5, DMU-22, DMU-2, and DMU-61. More comprehensive and extensive survey and analyses would be necessary in the future.
