Deficiencies are present in records management during the production stage of long-term electronic records preservation. As such, this study seeks to address these issues by introducing Cloud On-Nara System (On-Nara Document 2.0) at records management sites and providing various systems and linked services. In particular, the factors that degrade the continuity of long-term preservation in the records management process, from the production to the utilization of electronic records, in On-Nara Document 2.0 were identified, and the causes were analyzed in compliance with ISO 15486-1:2016 and the Public Records Act. As a result, in redesigning the records management procedure, the organization of the records management hub between systems and the conversion of the document preservation format for long-term preservation were proposed. Moreover, the application of consistent production format selection criteria and the reinforcement of the production and management of granular metadata were recorded. These measures were proposed in an effort to reestablish management methods.

This paper suggests a procedure of decomposing a multi-stage dynamic location problem into stages with respect stage. The problem can be formulated as a mixed integer programming problem, which is difficult to be solved directly. We perform a series of transformations in order to divide the problem into stages. In the process, the assumption of PSO (production-system-only) plays a critical role. The resulting subproblem becomes a typical single-stage dynamic location problem, whose efficient algorithms have been developed efficiently. An extension of this study is to find a method to integrate the solutions of subproblems for a final solution of the problem.

In this study, we developed a machine learning-based model for predicting the production stage temperature of distillation process. It is necessary to predict an accurate temperature for control because the control of the distillation process is done through the production stage temperature. The temperature in distillation process has a nonlinear complex relationship with other variables and time series data, so we used the recurrent neural network algorithms to predict temperature. In the model development process, by adjusting three recurrent neural network based algorithms, and batch size, we selected the most appropriate model for predicting the production stage temperature. LSTM₁₂₈ was selected as the most appropriate model for predicting the production stage temperature. The prediction performance of selected model for the actual temperature is RMSE of 0.0791 and R² of 0.924.

Now, the proportion of musical was strength in the stage art part to the past considerably as called musical boom. After 1990's, as if it was rise as rise of musical exclusive theater, it was development seriously in Korean musical. But presently, the examined musical product state as the ratio of import musical and creative musical is about 6 to 4 or 7 to 3, it was a inferiority of creative musical in a flood of import musical. So, this study researched for example Kim Kyun Hyoung' writing and Yu Min Suck' production, creative musical 'This is my destiny...' - played by Dept. of multimedia and film, Honam University in september 2007 - this researcher should give much theoretical and substantial assistance to stage costume producer by studying about producing costume of a aria story, a mental state. As I have studied sofar, in designing a stage costume for musical, the overall comprehension of the musical actor's bodies have to be considered. Though performing the manufacture of the really performance work. It is a field that needs various professional knowledge, and only when a musical is produced based on such theories, it will be possible to deliver the theme of the me of the play more effectively, becomes help in the efficiently theatrical costume manufacture realistically and express the various symbolical meanings.

Objective: This study was conducted to suggest a proper administration system of the quality of herbal medicine. Methods: Related literature was carefully inspected and discussions among specialists in the field of herbal medicine's growth, production, circulation and administration were conducted. Results: 1. The administration of herbal medicine's quality should be done in each stage of its circulation; growing stage, harvesting stage, importing stage, production stage, quality examination stage, wrapping stage, circulating stage, and administration stage. 2. A safety standard should be established for items, parts and origins of each medicinal herb. A standard for the identification of forged products and objective standards for quality discrimination should also be established. 3. A national system for the training of herbal medicine quality administration personnel and herbal medicine discrimination personnel should be established. A data base of standardized product specimens should be established and a pharmacopoeia of herbal medicine should be published as a standard of quality administration in herbal medicine. 4. Research into the following preliminary areas should be conducted to investigate quality adminstration of herbal medicine: research related to herbal medicine's raw materials and herbal medicinal drugs; quality estimation of raw materials and drugs; quality administration in oriental medical hospitals; herbal medicine administration law; herbal medicine administration organization; herbal medicinal pharmacology; and policy-related research for the quality improvement of domestically grown medicinal herbs. Conclusion: For the proper administration of herbal medicine's quality, governmental support and intensive research among specialists should be done for the supply of good quality medicinal herbs and the improvement of the efficacy of herbal medicine.

This study was carried out to investigate the growth responses of Pinus densiflora seedlings to enhanced UV-B environment for 16 weeks in the field condition. The seedlings were treated with one of three levels of UV-B dosages - ambient UV-B, ambient + 3.2, and ambient + 5.2 KJ m$^{-2}$day$^{-1}$ and the irradiation was performed at the stage before the germination, the fully expanded cotyledon, and the primary needles grown more than 0.8cm in length of the seedlings, respectively. Enhanced UV-B irradiation reduced the height and the root collar diameter growth, and dry mass production of the seedling, and T/R ratio was increased by the UV-B treatment. Difference in seedling growth was observed by difference in time of the UV-B treatment. Among the seedlings which were treated with ambient - 3.2 KJ m$^{-2}$day$^{-1}$, height and root collar diameter growth was relatively high in the seedling received the UV-B treatment at the stage before the germination. The lowest dry mass production was observed in the seedlings received the UV-B at stage of cotyledon both in two levels of enhanced UV-B treatment. Chlorophyll concentration was reduced by enhanced UV-B irradiation, and chlorophyll a/b ratio was increased by the UV-B treatment.

The cultivation area of rice as staple grains is decreasing in the domestic situation in Korea. Import volume of a duty in foreign rice is 409,000 tons for a year regardless increasing of production per unit area and decreasing of rice consumption. The total stock of rice is increasing cumulatively despite the effort for production mediation of rice. Therefore, maintenance of cultivation area and reduction of production are necessary for national foodstuffs security problems. Development of environment-friendly and low-carbon technology as alternative of global warming and aging of farm labor power is very important responsibility for descendants with creation of sustainable agriculture environment. As alternative for demand and supply stabilization of rice from all angles, first stage: extension of environment-friendly cultivation area as 17% Jeollanam-do level with maintenance of cultivation area under the present circumstances, second stage: extension of environment-friendly cultivation area as 25%, third stage: extension of environment-friendly cultivation area as 35%. From above mentioned scenario, reduction of rice production (60,000 tons), increases of production cost (59,200,000,000 Won), and reduction of income (201,500,000,000 Won) are estimated in first stage. Reduction of rice production (90,000 tons), increases of production cost (122,100,000,000 Won), and reduction of income (313,700,000,000 Won) are estimated in second stage. Reduction of rice production (380,000 tons), increases of production cost (222,000,000,000 Won), and reduction of income (464,500,000,000 Won) are estimated in third stage. From analysis results for partial tillage in transplanting cultivation complex (10ha), rice production is decreased 1.3~1.5 ton by complex. Production cost of rice is decreased and increases of income cultivation type. Gradual extension of environment-friendly agriculture and low-carbon partial tillage could be expected for environment maintenance of the territorial integrity, confidence of consumer, and high-efficiency of low-cost.
