This study was carried out to investigate factors influencing on the groundwater quality at controlled horticulture in Honam area in 1995. The deeper groundwater sampling, the lower concentrations of $NH_4-N$ and $NO_3-N$ were observed. There was no difference in concentrations of $SO_4\;^{2-}$ and $Na^+$ in the groundwater below 15m. Contents of $NH_4-N$, $NO_3-N$ and $PO_4\;^{3-}$ in groundwater were the highest at rice transplanting season(the late May) and that of $SO_4\;^{2-}$, $Na^+$ and $Cl^-$ were the highest at dry season(the mid-February). Continuous cultivation of horticultural crops showed higher concentration of $NH_4-N$, $NO_3-N$, $PO_4\;^{3-}$, $Na^+$ and $Cl^-$ in groundwater than rotational culture with rice. The longer cultivation years with horticultural crops, the higher concentrations of $NO_3-N$, $PO_4\;^{3-}$, $SO_4\;^{2-}$ and $Cl^-$ were shown, and constitutional ratio of $NO_3-N$ among the anions increased gradually. Nitrate-N level, exceeded 20mg/l, the critical level for agricultural usage, frequently at Yongjinmyeon Wanju and Janglockdong Kwangju, and $PO_4\;^{3-}$ levels were higher at Seogtandong Iksan than the other places.

A bibliographical review of Gy sampling theory for particulate materials was conducted to provide readers with useful means to reduce errors in soil contamination investigation. According to the Gy theory, the errors caused by the heterogeneous nature of soil include; the fundamental error (FE) caused by physical and chemical constitutional heterogeneity, the grouping and segregation error (GE) aroused from gravitational force, long-range heterogeneous fluctuation error ($CE_2$), the periodic heterogeneity fluctuation error ($CE_3$), and the materialization error (ME) generated during physical process of sample treatment. However, the accurate estimation of $CE_2$ and $CE_3$ cannot be estimated easily and only increasing sampling locations can reduce the magnitude of the errors. In addition, incremental sampling is the only method to reduce GE while grab sampling should be avoided as it introduces uncertainty and errors to the sampling process. Correct preparation and operation of sampling tools are important factors in reducing the incremental delimitation error (DE) and extraction error (EE) which are resulted from physical processes in the sampling. Therefore, Gy sampling theory can be used efficiently in planning a strategy for soil investigations of non-volatile and non-reactive samples.

Sasang Constitutional Medicine (SCM) suggests the concept of health condition which is owned of different properties by each Sasang Constitution. But SCM theory has concentrate to explaining different symptoms that distinguish health condition, not much concerned with practical methods like face features, pulse diagnosis, skin surface properties and voice features. Physical properties of practical diagnosis methods from literature finding have been researched. As a result, complexion and face moisture were described to be physical properties related to health State. In scope of pulse diagnosis, depth, rate, contour, width and pressure are related. Skin surfaces' elasticity, moisture, fraction properties were also suggested as factors of health State of Sasang Constitution. We assume that this study would contribute further studies for objectifying and quantifying diagnosis methods to evaluate health state grades of Sasang Constitution.

For civil servants in the legal sector, the best performance that must be shown is not how they carry out activities following standard operational procedures but what is more important is how they show Organizational Citizenship Behavior (OCB) in daily activities. This study aims to examine what factors influence the formation of OCB civil servants in the legal sector in Indonesia. The study was conducted on 145 civil servant respondents who were involved in secretarial activities, each from the Judicial Commission Secretariat, the Attorney General's Office, the Ministry of Justice, the Supreme Court, the Police Headquarters, and the Constitutional Court. The research methodology used Partial Least Square (PLS) Version 3.0. The empirical findings of the research show that organizational culture has a significant influence in shaping transformational leadership that can build OCB among civil servants in Indonesia. This effect is much larger and more significant than the compensation system, which is widely believed to be the main factor in forming OCB, such as the results of previous studies. The results of this study imply that the formation of an organizational culture with values that can create high work productivity which has an impact on transformational leadership styles in building OCB.

In order to secure practising rapid pattern(證, zheng) differentiation against acute infectious diseases like corona virus disease-19(COVID-19) showing rapid variation and contagion, a simplified classification of stages centering on the exterior-interior pattern identification with 2 step-subdivision by cold, heat, deficiency, excess pattern and pathogens is proposed. Pattern differentiation by compound patterns of 8 principles is made for the non-severe stage of general cold and the early mild stage of epidemic disease. Compound pattern's names of 8 principles about external infectious diseases are composed of three stages, that is disease site-characters-etiology. Based on early stage symptoms of fever or chilling etc., exterior, interior and half exterior and half interior patterns are determined first, and then cold, heat, deficiency, excess patterns of exterior and interior pattern respectively are determined, and then more concrete differentiation on pathogens of wind, dryness, dampness and dearth of qi, blood, yin, yang accompanied with constitutional and personal illness factors. Summarizing above descriptions, 4 patterns of exterior cold, exterior heat, exterior deficiency, exterior excess and their secondary compound patterns of exterior cold deficiency and exterior cold excess and so on are classified together with treatment method and available decoction for a standard measure of eight principle pattern differentiation.

Modern logistics significantly influences the globalization and internationalization processes. Logistics systems are becoming increasingly important in today's rapidly changing environment. On the other hand, the development of global economic integration, business globalization contributes to the creation and development of international logistics systems and global supply chains towards the international market. The aim of the article was to investigate the national logistics systems of developing countries in the context of their integration capabilities. The main methods used in this study are statistical analysis, index, graphical and analytical methods, methods for estimating structural dynamic shifts, comparisons. Commonly used methods of economic research, as well as statistical analysis and interstate comparisons, economic modelling (trend analysis to determine the forecast level of LPI for Ukraine), etc. were also involved. It is noted that the problem of development of logistics systems in developing countries was insufficiently covered in scientific research. The study suggests that the integration capabilities of national logistics systems are determined by the logistics performance of each country and the favourable logistics environment for integration transformations. This allowed analysing the state of the logistics systems of Poland, Bulgaria, India and Ukraine, and identifying the factors that determine it. The logistics environment of Poland, Bulgaria, India and Ukraine, as well as the factors of its formation are evaluated. The components of the logistic portrait of the country in the context of integration capabilities of the logistic system are offered. Trend analysis of LPI was carried out on the example of Ukraine, which showed positive trends in the logistics system and allowed drawing conclusions about increasing integration into international logistics channels based on its geopolitical location, improving the characteristics of the logistics environment, including customs regulation, and improving the efficiency of the national logistics system. Prospects for further research involve studies of the impact of pandemics, globalization, digitalization on logistics systems, including that of developing countries.

The primary reason for the uprising interest and research concerning constitutional medicine is due to a shift in paradigm; from one that treats based on symptoms to one that emphasizes unique personal traits such as living conditions and psychological factors. Of the Cheoninseongmyeong(天人性命), the components of Seongmyeong(性命) theory on constitutilnal medicine, this study discusses how the Hyegak(慧覺) of Juchaek(籌策), Gyeongryun(經綸), Haenggeom(行檢) and Doryang(度量), the 4 components of Sung(性), and the Ja-eop(資業) of Sikgyeon(識見), Wiui(威儀), Jaegan(材幹) and Bang-yak(方略), the 4 components of Myeong(命) are assigned to each of the 4 different constitutional types. Ultimate Hyegak[絶世之慧覺] and Goodman's Ja-eop[大人之資業] can change according to the individual's will to overcome one's shortcomings despite the correlations made between Hyegak(慧覺) and Ja-eop(資業) of the 4 elements of given Seongmyeong(性命) and the 4 constitutions. The focal point in the discussion of Dongmu's Jihaeng theory is that any flaws one might have ought to be overcome by following in the footsteps of others who are better and any gifts ought to be shared with those who don't have the privilege to enjoy it. Thus, from the fact that Dongmu's Jihaeng theory is not one that confines one to a certain body type but is meant to be the basis for realizing which paths, or Seongmyeong(性命), ought to be taken, we can learn how to overcome disadvantages due to body constitution. Furthermore, Dongmu's Suyang(修養) theory is significant and valuable in that it can not only be utilized to bring personal welfare and longevity but also to achieve a healthy and moral society.
