Forecasting daily box-office performance is critical for planning the distribution of marketing resources, and by extension, maximizing profits. For certain movies, the number of viewers increases rapidly at the beginning of their theatrical run, and the increments slow down later. Other movies are not popular in the beginning, but the audience sizes grow rapidly afterward. Thus, the audience attendance of movies grow in different trajectories, which are influenced by various factors including marketing budget, distributors, directors, actors, and word of mouth. In this paper, we propose a method for predicting the daily performance trajectory of running movies based on the hierarchical linear model. More specifically, we focus on the effect of online word of mouth on the shape of the growth curves. We fitted the mean trajectory of the cumulative audience size as a cubic function of time, and allowed the intercept and slope to vary movie-to-movie. Moreover, we fitted the linear slope with a function of online word of mouth predictors to help determine the shape of the trajectories. Finally, we provide performance predictions for individual movies.

As the use of electric vehicles perspectively increases, infrastructures for charging car batteries need to be properly planned for satisfying new requirements. This study aimed at theoretically investigating the relative laws, size of existing parking lots, and diverse car sizes for suggesting parking places for electric vehicles. In addition, potential problems for changing existing parking lots to new parking lots for electric vehicles were thoroughly considered. Based on the problem recognition, the feasibility, in particular, of the change of existing parking place to new place equipped with electricity charging systems was investigated. The comprehensive reviews and surveys revealed that additional systems for charging electricity need to be developed to be suspended on the ceiling for existing parking lots in order to prevent changing current layout of the space. This system will alleviate the perspective problems when the charging systems are located on the floor such as contamination, electric shock, and damage by cars. Further study will be followed for testing performance of the suggested systems in the actual parking lots.

This study analyzes relevant data based on the mid-sized rental unit. It focuses on how we can set up appropriate mid-sized rental unit plan as its supply has been accelerated over time. The questionnaires used in this study cover a series of categories including site environment, unit plan, neighborhood, economy, and management. The 342 respondents are from the 3-year old apartments at Cheongju. The key findings are as follows. 1) As the average indices including number of family, life cycle, and income under the survey are different in terms of the rental unit sizes between 20 and 30 pyeongs. 2) In general, residents present comparatively high level of satisfaction in terms of residential environments. Their evaluation on the site environment unit plan, and neighborhood is around the average. In contrast, the economic and management efficiency categories are under the average. This study suggests residential guidelines should be derived from tenant differentiation policies dealing with diverse socio-demographic characteristics and satisfaction level. 3) In terms of improvement priority, residents present, higher preference on the management system and site environment. This study advises to establish an appropriate alternative to guarantee effective tenant participation. Considering the lower satisfaction level in the green space, common facilities, and resting space, this study also urges to secure quality control for desirable planning of the mid-sized rental apartments.

This study established a lower garment sizing system for abdominal obesity adult women aged 30-59 based on 277 females selected from the 7th Size Korean Anthropometric survey. The criteria for subjects in this study were over 25 kg/㎡ of the BMI, over 85 cm of waist, and over 0.8 waist hip ratio. The results are as follows. The lower body analysis of abdominal obesity adult women showed that average circumference items were larger than the ordinary size, and the average length items were smaller. The standard deviation was applied around the average values of waist circumference and hip circumference for the suggestion of a lower garment sizing system for abdominal obesity adult women. The interval between the designation was ±1.5 cm with a waist circumference of 100 cm and ±2.5 cm with an average hip circumference of 100 cm. We established 13 designation sections in consideration of the cover ratio and cover efficiency. The cover ratio in the 13 nominal sections was 71.5%. The segmental distribution rate presented in the results will also be useful for production planning in specific sizes that helped enable rational production.

Morotoge shrimp Pandalopsis japonica is caught by pot and others in the eastern coastal waters of Korea. Comparative fishing experiments were carried out in the eastern coast of Korea, using the dome-shaped pots with different five mesh sizes (17.1, 24.8, 35.3, 39.8, and 48.3 mm) in order to estimate the mesh selectivity of the pot for the morotoge shrimp, Pandalopsis japonica. The SELECT (Share Each Length's Catch Total) analysis method was applied to the catch data. The master selection curve of the pot for the shrimp was estimated to be s(R) = exp(15.770R-10.573)/[1+exp(15.770R-10.753)], where R is the ratio of carapace length to mesh size. From the selection curves, the carapace lengths of 50% retention were 11.6, 17.0, 23.9, and 34.1 mm for 17, 25, 35, and 50 mm mesh-size pot, respectively. It means that the pots of larger mesh size allow more shrimp of small size to escape.

The purpose of the study is to analyze the residential mobility effects and planning discrepancies of home-owning households and renting households. The data for the empirical analysis were collected from 248 units residing in Ulsan and were studied using descriptive statistics, chi-squared tests by cross-tabulation and multiple regressions. The majority of the households did not experience a change in types of housing structure or ownership after the residential mobility. However, the housing size increased after residential mobility, showing that most moves were due to the deficit of housing sizes. In terms of future mobility plans, there were significant differences between home-owning households and renting households. More than two-thirds of the renting households were willing to move within 2-4 years to obtain home ownership. On the other hand, most home-owning households were willing to move for housing size, education of the head, and investment purposes. Compared to the forty-four percent of the home-owning households, seventy-two percent of the renting households were willing to relocate, which shows the effects of unstable housing circumstances.

Temporary scaffold systems in the construction site play an important role for ensuring the safety of the workers and for constructing the stable structures. To assemble the scaffold, the pipe scaffolding system, the wedge binding scaffolding system and the particular materials have been utilized. To design the material arrangement of a scaffold, firstly the configuration was determined considering the construction geometry. Then, the strength of the scaffold was confirmed and the quantity of the material was accounted. In this paper, the design method of the temporary scaffold was proposed for intending the semi-automatic procedure. In the proposed design method, the geometric design and the safety requirement were specified by the safety standard and the design flow was followed by the designer's knowledge. The size and the quantities of the materials were calculated by referring to the relation between the scaffold and the constructing structure. In the calculating procedure, three dimensional positions of each scaffold materials were calculated and recorded simultaneously. Then, three dimensional scaffold structural was drawn semi-automatically on the CAD software by using the obtained material sizes, positions and directions. The proposed design method provides us the precise quantities of scaffold materials and enables us to reduce the design effort and the cost estimation processes. In addition, the obtained results can be applied to BIM software after converting to IFC format.
