This paper examines how the concentration of ownership in firms influences the R&D investment decision and whether the type of a firm's management (i.e, the owner-manager or professional manger) differentiates the relationship between the ownership concentration and R&D investments by using data of Korean pharmaceutical companies between 2004 and 2008. The results show that the share of the largest shareholder and R&D investment have an inverted U-shaped relationship, and whether a CEO is an owner or a professional manager affects the curvature of the inverted U-shaped relationship. Specifically, when a firm's CEO is a professional manager and the share of his stock is small, increase in the CEO's share increases the R&D investment in the larger amount than when a firm's CEO is an owner. This is because the increase in ownership reduces agency cost; However, when the share of his stock is large, the increase in CEO's share decreases R&D investment in the larger amount than when a firm's CEO is an owner. This is because a professional manager gets concerned over excessive risk exposure more than an owner-manager does.

Accident prevention plan it a construction site should be analyzed and made with risk evaluation and management, from recent year, in Korea. Accidents occurred in construction site are related to all parties such as owner, main and subcontractor, labour. But analyzing some relationship between main and subcontractor is very important to estimate what risk between then are existed in a site. There are some different aspects concerning with risk management between them. Everywork has its own risk in there, This is the reason why everywork which are made by subcontractor himself should be evaluated for risk level. And main contractor should provide for subcontractor to prevent each risk at the work, all the time.

To prevent the use of one's smartphone by another user, the authentication checks the owner in several ways. However, whenever the owner does use his/her smartphone, this authentication requires an unnecessary action, and sometimes he/she finally decides not to use an authentication method. This can cause a fatal problem in the smartphone's security. We propose a sustainable android platform-based authentication mode to solve this security issue and to facilitate secure authentication. In the proposed model, a smartphone identifies the current situation and then performs the authentication. In order to define the risk of the situation, we conducted a survey and analyzed the survey results by age, location, behavior, etc. Finally, a demonstration program was implemented to show the relationship between risk and security authentication methods.

Multi-trade Contract Method was introduced as a means of cutting down construction cost of public housing for low income people. Before a specific project delivery method is applied to large public construction project, it is necessary to discuss all the issues raised up from all the parties in construction industry and all the issues which can impact project performance. Thus the interviews were conducted with industrial professionals from diverse organizations and previous studies were investigated to figure out how this newly introduced project delivery method may impact owner's role and responsibility and project performance in terms of cost, schedule, quality and risk. Under the Multi-trade Contract Method, project owner's management tasks will be highly increased, so it should be checked out if the owner can do its role and responsibility. Public owner's organization also needs to be changed and proper project management procedure and system need to be established. In addition, for efficient application of Multi-trade Contract Method, public owner should consider diverse management approach to deliver the project, and how to select and maintain qualified specialty trades.

The study investigates the impact of family ownership heterogeneity on the internationalization decisions of family-owned enterprises from ICT sectors in South Korea. The study uses prospect theory to explore the relationship between ownership structure and internationalization. The study finds that as performance improves, the ultimate owner (CEO) is negatively related to internationalization, while other family members are positively related, demonstrating the heterogeneous behavior of family members. The study suggests that the ultimate owner (CEO) tends to avoid risks associated with internationalization, while other family members are willing to take risks. To better understand the various risk behaviors of family firms regarding internationalization, the inherent heterogeneity of family firms, particularly in light of different risk behaviors between the ultimate owner (CEO) and other family members, may explain the inconsistent results in studies on the effect of family ownership on internationalization.

This research is a case study that focuses on how conglomerate illegality and corresponding penalty affects corporate performance and strategy. The research aims to provide base information for policy-makers as well as the general public about the corporate environment. The analysis results can be summarized as follows. First, profitability is represented as an M-curve. Profitability falls from indictment to the final pronouncement of the corporate head and increases upon his or her return. The result suggests that the absence of a corporate head could result in low profitability as the firm is exposed to owner risk. Secondly, significant effects on investment were not found. Investment showed a continuous increase from indictment to final judgment. This could have resulted from investment decisions made prior to the indictment, which are generally long-term. Meanwhile, the rate at which investments rose for core subsidiaries were lower, which makes it reasonable to suspect dwindling executive capacity due to the absence of a corporate head. Thirdly, employment showed a slight increase, but the rate was found to be greater during the periods following the final judgment. From a political perspective, this increase can be inferred from a give-and-take tradeoff between corporate employment and the pardon of the corporate head.

The Multi-family Residential is one of the most famous building types for a rental property in the US. Often times it includes multiple residential buildings and some amenity facilities, including a clubhouse or leasing office, swimming pool, dog park, and garages. Since the building type is built for rental purposes, the construction planning is phased and it makes the project complicated. Detailed planning and execution are important for successful construction management. This paper provides some management practices that are applied to one of the multi-family residential construction projects in Phoenix, AZ. The Front End Planning (FEP) process performed by both owner and contractor is the first key to a successful construction project. Specifically, the early review of phased turnover strategy, grading, fire/Americans with Disabilities Act (ADA) compliance, and Mechanical/ Electricity/Plumbing/Technology (MEPT) will provide absolute benefit to the project. Second, using a scheduling method to control short-term schedules and long-term can provide the ability to manage the issues with agility. Third, material delivery and procurement dominate the both project schedule and cost. With this COVID-19 circumstance, it is hard to expect the material, equipment, and labor forces to be delivered on time with the contracted price. Managing floats are more than important to managing construction productivity. Risk management should work to share the risks fairly. Lastly, turnover is directly linked with the profit of the project for both owner and contractor. The communication between the owner and contractor to re-schedule the proper turnover schedule is important for the phased construction project.

Background: Long-term comparisons of phacoemulsification with topical medication are limited in canine diabetic cataracts. Objectives: To compare outcomes of eyes submitted to phacoemulsification with those of topical medication for canine diabetic cataracts and identify risk factors for complications. Methods: Through medical records review, 150 eyes (76 dogs) with diabetic cataracts were included; 58 eyes (31 dogs) underwent phacoemulsification (phaco-group) and 92 eyes (48 dogs) received ophthalmic solution alone (medication-group). The medication-group was divided into owner-led and vet-led groups depending on who elected not to perform surgery. Comparisons involved time-to-complications, vision, and the number and type of ophthalmic solutions administered. The association between complications and pretreatment clinical findings was investigated. Results: No difference was found in complication risk between the phaco and owner-led medication groups. Conversely, the vet-led medication-group had a higher complication risk than the other groups. At the last follow-up, 94.8% of the phaco-group had vision, whereas 7.6% of the medication-group restored some visual axis. Poor glycemic control in the medication-group and younger age in the phaco-group increased complication risk. At 1-year post-treatment, the average number of ophthalmic solutions administered was 1.7 and 2.6 in the phaco and medication groups, respectively. The medication-group used anti-inflammatories the most throughout the follow-up, whereas the phaco-group used anti-inflammatories the most until 1-year post-treatment and lacrimostimulants at 1.5-year post-treatment. Conclusions: For canine diabetic cataracts, phacoemulsification is recommended because it is superior to topical management alone in terms of maintaining vision and reducing the number of ophthalmic solutions required in the long term.

The purpose of this study is to derive the risk factors that occurred during the construction of the temporary aircraft runway and to analyse the risk costs and loss costs. For this purpose, actual construction data made during the construction of the aircraft runway were investigated. And the risk factors that occurred during the construction work were derived. So the increased construction costs and loss costs due to risk factors were analyzed. The results of this study are as follows: 1)The number of risk factors that occurred during the construction of the aircraft runway was derived from eight. 2)It was calculated that the total risk cost of 5.2million won, the risk cost of the owner's should be 243 million won and the cost of the contractor should be 277million won. 3)Owner's was up 2.36% from its planned budget and the contractor lost -277million won out of its planned profit of 443million won, resulting in a residual profit of 165million won. The results of the study are used as a reference for estimating risk factors and contingency that should be considered in aircraft runway construction.

We need the contingency cost in order to deal with the uncertainty to be accompanied inevitably at the construction and an every kind risk not to forecast in advance. And also the contingency colt needed for the change order and we need it for reduction of the delay and reduce the trouble between owner and constructor. This study, through checking and analyzing the risk factor, in the step of domestic construction, suggests optimal management reserve to specific business about the contract type and the scale. The main results of this research are summarized as follow. First, I investigated the recognition about the contingency cost, grasped the risk to be happened at the construction step and found out the frequency occurrence, through making up question to engineer are carrying out their job in the domestic construction. Second, I computed optimal contingency cost rate by the statistics investigation, and proposed an improvement plan and problem when compute a contingency cost.
