Recently, the government provided about 35 trillion won to start-ups through a large amount of start-up support funds from the Korea Credit Guarantee Fund and the Korea Development Bank, and more than 100 trillion won to start-ups over the past three years.(2015-2018) The Ministry of SMEs and Startups announced that a total of 1.4517 trillion won will be supported by 16 ministries (90 projects) after surveying start-up support projects by ministries in 2020 to create a start-up country. Indeed, among the budgets supported by the Ministry of SMEs and Startups, startups accounted for 85%, while scale-ups (growth and maturity) were only 15%. However, the survival rate of Korean start-ups was far lower than that of developed countries. The survival rate for the three years after the start-up was 39.1 percent, with only about 4 out of 10 surviving, with 27.5 percent surviving for five years, and only 3 out of 10 surviving. On the other hand, overseas start-ups have a survival rate of twice as high as that of Korea for five years. Accordingly, this study aims to empirically analyze and examine the need for research on nascent entrepreneurs, which have recently been actively supported by the government, as well as the impact of start-up motivation and start-up preparation on the intention to continue business. The survey was conducted from April 1 to May 15, 2020 for nascent entrepreneurs nationwide, and 222 of the total 245 copies were analyzed, and the questionnaire was measured using the Likert 5-point scale. As a result of the analysis, first, all factors constituting start-up motivation were adopted by significantly affecting start-up satisfaction. In addition, among the sub-factors of nascent entrepreneurs' preparation, item preparation was adopted as a significant influence on start-up satisfaction. Second, the nascent entrepreneurs' satisfaction level was adopted by having a significant impact on the business continuity. Third, some of the motivations for self-realization of the motivation for start-ups were adopted by having a significant impact on the business continuity. In addition, the preparation of items for the start-up preparation of nascent entrepreneurs was partially adopted as they had a significant impact on the business continuity. Fourth, it was adopted by the mediation effect of start-up satisfaction between the motivation of the nascent entrepreneurs' preparation and the business continuity. In addition, it was adopted by the medium effect of start-up satisfaction between the nascent entrepreneurs' preparation and the business continuity. Based on the results of these studies, it is intended to draw practical implications, and to provide useful policy implications to increase nascent entrepreneurs' satisfaction and continue to carry out their start-ups.

A result of Hardy and Littlewood relates Holder continuity of analytic functions in the unit disk with a bound on the derivative. Gehring and Martio extended this result to the class of uniform domains. We call it the Hardy-Littlewood property. Langmeyer further extended their result to the class of John disks in terms of the inner length metric. We call it the Hardy-Littlewood property with the inner length metric. In this paper we give several properties of a domain which satisfies the Hardy-Littlewood property with the inner length metric. Also we show some results on the Holder continuity of conjugate harmonic functions in various domains.

We introduce the notion of the mean Bocce dentable and provide the geometric characterization of the CCP. We show that X has the CCP if and only if every bounded subset of X is mean Bocce dentable.

Identification theory for linear discrete system has been presented by a great many reference, but research works for identification of continuous-time system are less than preceding identification. In fact, a great man), systems for engineering are continuous-time systems, hence, research for identification of continuous-time system has important meaning. This paper offers the following results: 1. Corresponding relations for the parameters of continuous-time model and discrete model may be shown, when single input-output system has general characteristic roots. 2. To do identification of single variable continuity linear system with stability constraints from samples of input-output data, it is necessary to use optimization with stability constraints. 3. Main results of this paper may be explained by a simple example.

In general relativity, analyzing causality is central to the study of black holes, to cosmology, and to each of the major recent mathematical theorems. By causality we refer to the general question of which points in a space-time can be joined by causal curves; relativistically which events can influence (be influenced by) a given event. Various causality conditions have been developed for space-times of the problems associated with examples of causality violations (2, 4). Causally continuous space-times were defined by Hawking and Sachs (5). Budic and Sachs (3) established causal completion. A metrizable topology on the causal completion of a causally continuous space-time was studied by Beem(1). Recently the region of space-time where causal continuity is violated was studied by Ishikawa (6) and Vyas and Akolia (8). In this paper we show characterization for reflectingness in terms of continuity of set valued functions. We investigate some properties of the region related to a causally continuous space-time where distinguishingness is violated, and characterize the chronology condition in terms of distinguishing-violated region.

In order to model blending surfaces with curvature continuity, in this paper we apply sixth order partial differential equations (PDEs), which are solved with a composite power series based method. The proposed composite power series based approach meets boundary conditions exactly, minimises the errors of the PDEs, and creates almost as accurate blending surfaces as those from the closed form solution that is the most accurate but achievable only for some simple blending problems. Since only a few unknown constants are involved, the proposed method is comparable with the closed form solution in terms of computational efficiency. Moreover, it can be used to construct 3- or 4-sided patches through the satisfaction of continuities along all edges of the patches. Therefore, the developed method is simpler and more efficient than numerical methods, more powerful than the analytical methods, and can be implemented into an effective tool for the generation and manipulation of complex free-form surfaces.

Landscape structure is important to understand a complex patterns and interaction with adjacent habitat in rural area. The aim of this study is to analyze relationship between landscape structure and insect spatial distribution in rural area to suggest applicable possibility of landscape structure as biological indicator. For this purpose, first, four landscape structure criteria such as distance from the forest; density of farmland-forest ecotone; landscape continuity; and field size are selected. Secondly, these criteria are applied to Gangsang-myeon, Yangpyeong-gun where mosaic feature are conserved at various spatial scale. Thirdly, application of landscape structure criteria is verified using correlation with species number, species diversity, and species richness of insect. As a result, it could be suggested that the landscape structure criteria are useful for explaining insect spatial distribution.

The purpose of the establishment of corporation's Business Continuity Plan(BCP) is to maintain corporations' own business and establish the response plan in order to resume operation in a short time period when crisis situations occur due to natural disaster and human error. This study has presented all types of procedures and criteria which are needed to establish the airport crisis response system in order to maintain the business continuity by utilizing BCP technique. Basically the risk response procedures must be established in the process of (1) preparation stage, (2) plan development stage, (3) documentation stage, (4) test & maintenance stage. The guideline has been suggested that each stage must be carried out in the sequence of Policy & Planning Responsibility, Business Impact Analysis, Recovery Strategy & Plans, Emergency Plan & SOP, Training Awareness and Maintenance & Review

For topological spaces X, Y and the function f : X → Y, it induces a function gr(f) : X → X x Y defined as gr(f)(χ) = (χ, f(χ)), for every χ ∈ X. It deals with some preliminary investigations relating to the behavior of functions and its graph functions. It has also been found that continuous functions are homotopic if and only if their graph functions are homotopic.
