Advances in technology have made it easier for organizations to share information and collaborate. However, collaboration systems where multiple entities share and access information are vulnerable to security. The concept of Software Bill Of Materials (SBOM) has emerged as a way to strengthen information security by identifying and transparently managing the components of software programs. To promote the adoption of SBOM in Korea, this study investigated the intention to use of collaboration system managers. This study was based on the theory of planned behavior and the integrated technology acceptance theory. The results of this study confirmed that performance expectations from SBOM adoption were an important variable for intention to use, and positive attitudes toward security also had an indirect effect through performance expectations. We found that SBOM adoption has an important causal relationship with performance due to the fact that it is targeted at enterprises, and that positive attitudes toward security and social climate can have a strong effect on intention to use.

With the development of ICT, the use of software has become essential for organizations to exchange information or manage operations. However, security and software management issues that have increased with the development of ICT are issues that need to be continuously addressed. In 2021, the U.S. government has standardized and established SBOM as one of the countermeasures for software security. This research was initiated as a study to lay the groundwork for the introduction of SBOM in Korea. Based on the effects of SBOM characteristics on adoption intention, we tested management support and institutional support as moderating variables. As a result, security management was found to be a significant moderating variable for management support, and transparency was found to be a significant moderating variable for government institutional support. This study verified that SBOM adoption requires both corporate and government efforts, and the variables that are important from each perspective are different. We hope that this study will contribute to the development and adoption of SBOM.

Even though rarely recognized as a separate approach, the institutional approach in geography is defined as an attempt to seek an explanation of the phenomena of geographical interest through focusing on the effects of institutional structure and actions. It can provide interdisciplinary links with other works and can offer complementary explanations for geographical interests. The concerns for institutions in geography can be found in early studies, the study of the state, the managerial approach, and the regulation approach. The Korean financial systems can provide good examples to apply institutional concepts into creating spatial outcomes, as it has been regarded as a useful tool to promote Korean economic development. Behind the current spatial pattern of financial systems, four different stages of institutional changes are identified in Korea. Each stage has different institutional features reflecting unique spatial implication.

Twenty four weaner lambs, eight each of Marwari, Patanwadi and Merino${\times}$Patanwadi breeds (9.9 to 10.8 kg) were randomly divided into two dietary treatments on body weight basis Viz. $T_1$-conventional (Maize-38%, GN Cake-25%, Rice Polish-24%, Jaggery solution-10%, Mineral mixture-3%) and $T_2$-supplemented non conventional group (GN Cake-25%, Rice Polish-14%, Mango seed kernel-25%, Babul Pods chuni-23%, Jaggery solution-10%, Mineral mixture-3%). The Jaggery solution was prepared by mixing 6.5 kg Jaggery and 3.5 kg water. The average final body weight at the end of the experiment was recorded to be $19.33{\pm}0.76$ and $19.72{\pm}0.8kg$ in conventional and non-conventional groups, respectively. The total dry matter intake (DMI) during the entire experiment period was recorded to be $89.56{\pm}5.19$ and $95.08{\pm}1.06$ (kg/head) and $532.83{\pm}9.94$ and $566.75{\pm}10.49g/d$ in conventional and nonconventional groups, respectively. The body weight gain and body measurements did not influenced by diet. The ration effect was found to be significant when the DMI was expressed in terms of g/d. The crude protein (CP) and digestible crude protein (DCP) intake/head and per kg gain observed during experiment under conventional and non-conventional treatment group did not differ from each other. However, the total digestible nutrients (TDN) intake per kg gain was significantly (p<0.05) higher in supplemented non-conventional group. The intake values of DCP and TDN were more or less in agreement with Indian Council Agricultural Research (1985) recommendations. The estimated total feed cost (Rs./animal) for experimental lambs was $274.16{\pm}8.57$ and $242.67{\pm}5.10$ in conventional and non- group, respectively. The non-conventional group had significantly (p<0.05) lower feed cost (11.6%). The return as percent of feed cost and feed cost/kg dressed weight were $92.89{\pm}5.58$ (%) and Rs. $35.40{\pm}1.11$ and $122.61{\pm}5.06$ (%) and Rs.$30.47{\pm}1.71$ in conventional and non-conventional group (p<0.05), respectively which is the reflection of significantly lower total feed cost incurred during feeding in non-conventional group. Lambs fed non-conventional based diet had similar live weights as those fed conventional diets but costed less money to achieve those weights.

Trend surface analysis (TSA) was selected to estimate a natural trend in precipitation and to examine urban influences on precipitation over five urban areas (Houston, Dallas, and San Antonio, TX; New Orleans, LA; and Memphis, TN) in the southern United States. TSA was applied to monthly, seasonal and annual normal precipitation data for the period of 1961-1990. Winter and spring have more trends than summer and fall and the period of November through March have more marked trends than the period of April through October in all study areas except the Houston area. Residual maps for Houston, Dallas and San Antonio have positive residuals in the city and downwind during summer indicating that urban effects on precipitation enhancement in these areas do exist during these seasons after eliminating the natural precipitation variations. Summer residual maps for New Orleans and Memphis have no distinct precipitation increases due to urban effects. The June residual map in New Orleans and the July residual map in Memphis have positive values in the city, but the magnitude of values is smaller than other cities.

This study aims to examine the effect of leader' behavioral integrity on subordinate's change-oriented OCB via their team commitment along with the moderating effect of LMX. For this, 395 soldiers from military organizations where external factors were relatively well controlled besides their personal characteristics were selected and surveyed using hierarchical regression methods. First, the results showed that leader' behavioral integrity was positively related to subordinate's change-oriented OCB. Second, the positive relationship between leader' behavioral integrity and subordinate's change-oriented OCB was mediated by team commitment. Third, the aforementioned mediated relationship was moderated by LMX. Although this study targeted members of military organizations with more restrictions on behavior than private organizations, such as corporations, it could be meaningful in that it confirmed that the leader's behavioral integrity lead to subordinate's voluntary behavior of change-oriented OCB, which should be followed by efforts to make it more general by comparing a variety of public and business organizations.

The Last PlannerSystem (LPS) has been implemented on construction projects to increase work flow reliability, a precondition for project performance againstproductivity and progress targets. The LPS encompasses four tiers of planning processes:master scheduling, phase scheduling, lookahead planning, and commitment / weeklywork planning. This research highlights deficiencies in the current implementation of LPS including poor lookahead planning which results in poor linkage between weeklywork plans and the master schedule. This poor linkage undetermines the ability of theweekly work planning process to select for execution tasks that are critical to projectsuccess. As a result, percent plan complete (PPC) becomes a weak indicator of project progress. The purpose of this research is to improve lookahead planning (the bridgebetween weekly work planning and master scheduling), improve PPC, and improve theselection of tasks that are critical to project success by increasing the link betweenShould, Can, Will, and Did (components of the LPS), thereby rendering PPC a betterindicator of project progress. The research employs the case study research method to describe deficiencies inthe current implementation of the LPS and suggest guidelines for a better application ofLPS in general and lookahead planning in particular. It then introduces an analyticalsimulation model to analyze the lookahead planning process. This is done by examining the impact on PPC of increasing two lookahead planning performance metrics: tasksanticipated (TA) and tasks made ready (TMR). Finally, the research investigates theimportance of the lookahead planning functions: identification and removal ofconstraints, task breakdown, and operations design.The research findings confirm the positive impact of improving lookaheadplanning (i.e., TA and TMR) on PPC. It also recognizes the need to perform lookaheadplanning differently for three types of work involving different levels of uncertainty:stable work, medium uncertainty work, and highly emergent work.The research confirms the LPS rules for practice and specifically the need to planin greater detail as time gets closer to performing the work. It highlights the role of LPSas a production system that incorporates deliberate planning (predetermined andoptimized) and situated planning (flexible and adaptive). Finally, the research presents recommendations for production planningimprovements in three areas: process related, (suggesting guidelines for practice),technical, (highlighting issues with current software programs and advocating theinclusion of collaborative planning capability), and organizational improvements(suggesting transitional steps when applying the LPS).
