The manual handling of people (MHP) is known to be associated with high incidence of musculoskeletal disorders for aged care staff. Environment-related MHP interventions, such as appropriate seated heights to aid sit-to-stand transfers, can reduce staff injury while improving the patient's mobility. Promoting patient mobility within the manual handling interaction is an endorsed MHP risk control intervention strategy. This article provides a narrative review of the types of MHP environmental controls that can improve mobility, as well as the extent to which these environmental controls are considered in MHP risk management and assessment tools. Although a range of possible environmental interventions exist, current tools only consider these in a limited manner. Development of an assessment tool that more comprehensively covers environmental strategies in MHP risk management could help reduce staff injury and improve resident mobility through auditing existing practices and guiding the design of new and refurbished aged care facilities.

Handles on objects are very important to increase the safety and efficiency of manual handling of people who use them. In this study, four different prototype cartons combined with auxiliary handles were designed to determine the optimal handle position of cartons through the evaluation of user preferences. Twenty male students are participated in the experiment. Likert-5 point summated rating method was applied to evaluate the user preferences for provided handles of the carton among upper, middle, and lower position under the four different sizes and materials handling conditions(carrying positions). The results show that the subjects preferred upper part of the handle on the small cartons regardless of the carrying positions while upper and middle parts of the handle on the big cartons for handling above the waist height were preferred. An optimal handle position depending on the different sizes of carton and the different carrying positions were recommended based on the results of evaluation. It is thus recommended that the cartons provide handles on its relevant position depending on the size and materials handling condition to reduce the musculoskeletal stress and in turn to increase the user satisfaction.

In this study, a prototype liquid container combined with auxiliary handles was designed to increase the safety of manual handling and protect from contamination of hands of people who use these containers. Likert summated rating method as well as pairwise ranking test was applied to evaluate the user preferences for provided handles of the container under the conditions of different shapes and positions. The results show that the subjects preferred perpendicular orientation of the handle on the top of the liquid container while carrying the containers and the crosswise position of the handle at the side of the container while pouring the liquid were preferred. A prototype liquid container with provided auxiliary handles was developed based on the results of evaluation. It is thus recommended that the liquid container provide extra handles to reduce the musculoskeletal stress and in turn to increase the user satisfaction.

In these days many people have studied on the berthing problem. The operation rules differ from port so port and the problem is highly dependent on the environment of port. The purpose of this study is to develop a decision support system decision makers of the berthing problem for Inchon Port. The system is developed with graphic user interface(GUI) using user-interactive approach and some general and specific rules for Inchon Prot are considered. The system is composed of the following four parts ; the input/output part, the automatic berthing part by the system using rules, the manual berthing part by user, and the part for modifying results or handling exceptional events. The system is designed to assign ship to berths by matching the characteristics with environmental and operational constraints of Inchon Port. We expect that this system can provide decision makers with an efficient and fast way to berthing and can reduce wastes of time, space, and manpower in port operations.

Comparing with Seoul city's other administrative works, the work to arrange and collect monthly water rates with 470,000 faucets is tremendous in volume and simple repetition in quality. In order to cover the shortage of handling, it is urgent for us to replace the present manual system with EDP(Electronic Data Processing) system to mechanize a series of handling works of simple repeated calculation such as water consumption, rate calculation, statistics arrangement, bills and specification of water rate by computer. When this work is completely mechanized, inspectors of water meter just turn over their checking results to the Data Center and all data are processed through Input Media(OMR Card, Punched Card) and computer for programming final bills. Then, the delivery of the bills to citizens will be the only work to be carried out. such mechanization will bring about the following benefits: 1. Improvement of administrative work by efficiency and rationalization. 2. Improvement of administrative service with people. 3. Possibility of scientific with trustworthy multi-purpose policy-making data. 4. An effect to cover the personnel shortage of 252 persons (at all the water works offices) and save manpower of 166 persons (47,619 man-days). The application of the above mentioned mechanization will be started to only Chongro and Chung-ku water works offices as model cases out of all water works offices in Seoul. As the electronic calculating machines are inducted, this system will be gradually applied to other water works offices. The billing and collection works of water rates which are connected directly to the daily life of the citizenes, should be handled by the scientific EDP system as soon as possible in order to promote the convenience of consumers and effective operation. This study is to promote the sound and rational operation of this work.

The purpose of this study, during the lifting task was researching the difference and a relationship between the ground reaction force and the grip strength by change of position. After grip strength has measured in symmetry position and asymmetry position at 45cm and 75cm of height of hand, ground reaction force was measured by same attitude lifting wooden box. We analyzed the difference of grip strength and ground reaction force in each position change. The results of grip strength, the grip strength of both hand were significant difference that in study subject symmetry and asymmetry position (p<0.01). The results of symmetry lifting task, the study subjects was significant difference of the ground reaction force difference by height (p<0.05). Asymmetry lifting task was significant difference of ground reaction force difference by direction of rotation was changed (p<0.01). The result of it will rotate with non-dominant hand side of lifting tasks from height 75cm where it easily maintains a balance possibility and decreasing the load of the hand. Therefore, from the workshop in the work people, it will be between the height 75cm and non-dominant hand side of trunk rotatory direction in the lifting tasks. Future study is necessary researched about the change of grip strength when the height of the hand is higher, and the difference of the ground reaction force when the change of weight.

Purpose: The purpose of this paper is to analyze accidents and potential risks occurring at container terminals and to conduct on safety management plans tailored to container terminals. Method: A model for establishing a safety management plan is presented through a case study of container terminal risk assessment and literature analysis. Result: According to the 'Statistics of Accidents in the Harbor Handling Industry', 2,800 people were killed or injured during port work for 10 years from 2011 to 2021. This corresponds to an occupational accident rate of one person every 1.5 days. As a method of improving these accidents and disasters, a highly effective safety management plan should be established to prevent the recurrence of accidents in accordance with the Special Act on Port Safety. It is proposed to establish a safety management plan that reflects the risk assessment of container terminals, safety organization, safety budget, safety rules, and safety education.

Jo, Hee-ryong(1789-1866), who was given the title of "boss of the world handling a China inkt" in the late Joseon Dynasty, was from a noble family, but he claimed to be a yeohang-in himself. The byeoggyesa was formed based on Jong-in and they are engaged in literary activities. Hee-ryong Jo, "I do not follow people's back" is the art spirit of my life. The theory of the Holy Spirit has inspired emotion or inspiration as the essence of art. He pursued original aesthetics of painting with the true nature and personality as important. During his early 60s, the period of banishment for about three years had a profound impact on the identity and direction of his art world. During this period, he wrote four volumes, including "Hwaguamlanmug", "Uhaeagamgo", "Sugyeongjaehaeoejeogdog", "Hanwaheonjehwajabjon" and among his paintings with 19 paintings, eight paintings were produced, including "Hwangsannaengundo", "Bangunlimsansudo", "Maehwaseoogdo". These works reveal the Playful sokmi sprit, the grotesque of manual dexterity, and the aesthetic of painting through the natural divergence of natural nature.
