  • Laws regarding to Arbitration in North Korea are Arbitration Act, Foreign Economic Arbitration Act, Regulations on the Foreign Trade Arbitration Commission, Regulation for treatment of cases in Arbitration Commission, Rules of Hearing. North Korea has enacted the laws related to Arbitration including Arbitration Act enacted in 1995 and Foreign Economic Arbitration Act enacted in 1999. In the North Korea's planed economy system, as there will be many disputes among organizations, companies, other Institutions Arbitration Act resolves the disputes to compete the economic plan. North Korea's Arbitration Act is different from Normal Arbitration Acts in particular other socialist states in view of arbitration agreement and selection of arbitrator and functions as the tools controlling the members of North Korea and have the characteristics such as national arbitration system and mixture of criminal trial and governmental control and strict legal control system on violent acts in North Korea's plan and plan regulation. And North Korea's Arbitration Act deals with the civil disputes and limits the parties and subject matter of arbitration. The parties in dispute such as organizations, companies, other Institutions could apply for arbitration to Central Arbitration Body and Provincial (City under the direct control of Government) Arbitration Body and Sectional Arbitration Body. The purpose of this paper is to contribute to the enhancement of the understanding arbitration in North Korea by studying the clauses in the Arbitration Act.

  • In this paper, characteristics of infrasound and low-frequency noise emission from large modern wind turbines are experimentally investigated. The sound measurement procedures of IEC 61400-11 and ISO 7196 are utilized to field test and evaluation of noise emission from each of 1.5 MW and 660 kW wind turbines using the stall regulation and the pitch control for the power regulation, respectively. It was found that the G-weighted SPLs of low-frequency noise including infrasound shows positive correlation with the wind speeds, irrespective of methods of power regulation. This highlights the potential complaint of local community against the infrasound and low-frequency noise of wind turbines. The comparison of measured data with the existing hearing thresholds and criteria curves shows that it is highly probable that the low-frequency noise from the 1.5 MW and 660 kW wind turbines in the frequency range over 30 Hz leads to the psychological complaint of ordinary adults, and that the infrasound in the frequency range from 5 Hz to 8 Hz causes the complaint by rattling the house fitting such as doors and windows.

  • In recent years, the rapid growth of portable electronic devices requires the high-energy density characteristics of batteries. Zinc air batteries have specific capacity as high as 820mAh/g. However, Zinc air batteries used for hearing aid applications only so far, because the atmosphere could affect it, and it has weakness in the rate capability. However, recent developments of electrode manufacturing technologies made us to overcome that weakness. And the efforts of applying zinc air batteries to portable electronic devices, especially in cellular phone application have been increased. In this paper, the effects of conducting material and polymer binder in cathode on the electrochemical characteristics were investigated. Our research team succeeded in producing 2.4Ah class zinc air battery for cellular phone application. Its volumetric energy density was 920 wh/l, and gravimetric energy density was 308 wh/kg. The volumetric energy density of our zinc air battery is two times higher than one of lithium secondary battery, and three times higher than that of alkaline manganese battery.

  • Objectives The purpose of this study was to examine the psychiatric characteristics of outpatients with tinnitus. Methods A total of 88 subjects were included in this study. According to Tinnitus Handicap Inventory (THI) scores, the subjects were classified into two group ; a mild tinnitus symptoms (mild-tinnitus) group and a severe tinnitus symptoms (severe-tinnitus) group. A questionnaire was used for an assessment of demographic characteristics, and the THI, the Visual Analogue Scale (VAS) about tinnitus, the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI) are applied for evaluation of other clinical psychiatric characteristics. Results Higher THI scores were positively correlated with tinnitus course, the number of accompanying symptoms, and the VAS. BDI total scores, BDI factors, and BAI total scores were significantly higher in the severe-tinnitus group than in the mild-tinnitus group. Also suicidal ideation, interpersonal problems, sleep problems, occupational impairment, and fatigue were significantly higher in the severe-tinnitus group than in the mild-tinnitus group. Conclusions Tinnitus is a common disorder of hearing which is associated frequently with psychiatric problems. This study suggests that psychiatric interventions should be taken into consideration in the treatment of patients suffering from tinnitus.

  • In recent years, Korean population aged 65 and over has grown faster(7.2% in 2000, 14.4% projected in 2018 and 20.0% in 2026) than the other age groups and average life expectancy has increased from 65.8 years in 1980 to 75.9 years in 2000. The Aging Simulation Center(ASC) was built for people to give educational chance for further understanding of the elderly and the environment for the aged. People are able to recognize the changes including hearing loss, vision changes, and changes in the ability to touch and move after experiencing the simulated daily life of older persons. In general, ASC is composed of residential setting area and exhibition area of daily commodities for the elderly and care person. Currently, there are four ASCs in Korea. The purpose of this study is to evaluate the characteristics of space design and design elements of ASCs and to suggest design implementation for better residential environment for the elderly. For the research purpose, design characteristics such as floor plans and spatial design elements of three ASCs were analyzed and compared. As a whole, space design of three ASCs was almost same without distinguished characteristics. The major finding of this study indicates that the ASC is considerably helpful environment to understand aging. However, some of design elements such as lighting should be supplemented for safety issue. It is recommended for future design of ASC to include exterior space including outdoor stairs, paths and roads and so on. In addition, reception and preparation area should be arranged with universally designed furniture.

  • Older drivers have an increased risk of accidents due to poor function, but they also develop self-regulation ability to check their own changes. Thus, information on whether the actual elderly driver responds to changes in driving ability and risk may provide a meaningful basis for the clinic and research of the elderly's driving ability assessment. Therefore, the purpose of this study is to provide basic data for the evaluation of elderly drivers by analyzing the driving risk self-perception characteristics in terms of driving behavior and function with Korean elderly drivers. A self-reporting assessment was conducted on 500 elderly drivers living in the community and the characteristics of driving risk perception were analyzed. As a result, it was confirmed that many elderly drivers are aware of the driving risk when their vision and hearing are impaired or when they find it difficult to adapt to changes in driving conditions. On the other hand, the characteristics of insensitive reactions to changes in medical health conditions, such as drug use or epilepsy, seizures, and loss of consciousness, were identified. The researcher hopes this study will contribute to the safety management of elderly drivers in Korea, where aging is accelerating.
