This study was performed to investigate purchasing practice and size satisfaction in order to establish marketing strategy and produce free-size clothes for the male and female in their 20s. Results were as follows; first, regarding the size selection method, it has been found that 71.5% of subjects answered that they buy clothes as a sales clerk chooses for them without knowing the old size name or notation. Second, 47.5% of subjects answered that free size is the size, which fits well to 55~66 size. Meanwhile, 36.1% answered that free size fits well to any body type; while 4% answered that free size fits well to 77 size. Third, regarding the clothes kind, which consumers buy most as free size, consumers buy shirts and sportswear by free size. Fourth, they were observed to purchase free-size clothes "free-size clothes what I want" and to not purchase clothes "due to the lack of right sizes." The size notation of clothes products is basic information, by which consumers can tell whether the clothes fit to self or not before the consumer would wear the clothes and confirm its fitness. Therefore, it is suggested that all clothes products would be manufactured by having KS clothes size as basic data and they would use standard size notation so that consumers would not have confusion. Standardized size notation by proper education and utilization on new KS notation method and attitude change of companies and consumers on size are suggested.

This paper proposes a real-time dynamic storage allocation algorithm QSHF(quick-segregated-half-fit) that provides various memory allocation policies. that manages a free block list per each word size for memory requests of small size good(segregated)-fit policy that manages a free list per proper range size for medium size requests and half-fit policy that manages a free list per proper range size for medium size requests and half-fit policy that manages a free list per each power of 2 size for large size requests. The proposed algorithm has the time complexit O(1) and makes us able to easily estimate the worst case execution time(WCET). This paper also suggests two algorithm that finds the proper free list for the requested memory size in predictable time and if the found list is empty then finds next available non-empty free list in fixed time. In order to confirm efficiency of the proposed algorithm we simulated the memory utilization of each memory allocation policy. The simulation result showed that each policy guarantees the constant WCET regardless of memory size but they have trade-off between memory utilization and list management overhead.

Background : Hospitals in Korea are in trouble at ecomomic matters because of low cost of medical insurance, and consumers' demand for high quality. The management of inpatient clothing is very difficult. Especially the management of patient's clothing size is very difficult because the case mix of patients in wards is very different from the stocked clothing size. Because of the economic matters, the ward does not prepare enough size of clothing. The nurses in ward are in trouble with managing the clothing. So the nurses want free size patient clothing for ease management of clothing size. Method : The experimental inpatinets clothing is designed for in 170cm height refer to Korean standard. The fit of 8 subjects from 150 cm to 185 cm wearing experimental were evaluated by clothing specialists, nurses and patients. Result : 75.8% of evaluators like free size clothing. This results show that the fit of subjects from 160cm to 180cm was good in general but subjects with 150cm, 155cm, 185cm height showed poor fit.

Hardware implemented ring buffer systems and methods are presented for the effective management of the ring buffer in TCP/IP communication. The layer interface of the ring buffer systems transfer free buffer and used buffer size information to the TCP/IP stack upper or low layer. The pointer updation interface calculates a temporary pointer from the data size which is needed by the present pointer of the ring buffer and upper or lowyer layer. The pointer manager of the ring buffer systems is responsible for saving the present pointer of the ring buffer, updating the ring buffer pointer to the new pointer, calculating the free buffer size and used buffer size of the ring buffer, and transferring the information to the upper layer. The ring buffer systems help the TCP/IP layer and TCP/IP upper or lower layer to decide the sending or receiving data size effectively. The delay of transferring data can be lowered by the ring buffer system.

Hospitals in Korea are having trouble with economic matters because of the low cost of medical insurance and the consumer's demand for high-quality care. The management of patient clothing is very difficult Especially for the management of size is very difficult because the mix of patients in the wards is very different from the stocked clothing sizes. Because of economic matters the ward dose not prepare enough clothing for every size. The nurses in the wards have trouble managing the clothing. Therefore the nurses want free-size patient clothing for all patients. The problem of managing the patient's clothing were surveyed by nureses in the wards. It was known that the free-size patient clothing was needed. The clothing designed from 150cm, to 180cm by 5cm were made. The different sizes of clothing were pretested. The experimental clothing were selected. The experimental patient clothing are designed for between from 165cm and 170cm in height which refers to Korean average. The fitness and sensory test were made by medical personnel outpatient who will be future client for hospital and by specialist in clothing. Finally The free-size patient clothing was made. It was said that there is no difference between the C-type (170cm) and the D-typer(165cm) clothing by specialists in clothing. The outpatient future client for hospital liked the C-type was selected. The questionnaires of the C-type patient clothing was tested by outpatient patients and by medical personnel. Eighty-four point-eightprecent(84.8%) of evaluators liked free-size clothing 75.8% liked unisex use.

In this paper, the effects of ground size on the characteristics such as input resistance, fractional bandwidth, and radiation efficiency of epsilon negative (ENG) zeroth order resonance (ZOR) antennas were investigated theoratically. Two types of ENG ZOR antennas were studied: mushroom ENG ZOR antenna with via and via-free defected ground structure (DGS) ENG ZOR antenna. It was confirmed that the ground size had more effects on the characteristics of a Via-free ZOR antenna than those of mushroom ZOR antenna with via. The via-free antenna could radiate properly with the required size of ground plane since the size of ground plane should exceed some critical value for DGS to suitably operate. As a height of substrate of mushroom ZOR antenna with via increased, the fractional bandwidth and radiation efficiency were improved. On the other hand, as a height of via-free ZOR antenna increased, the fractional bandwidth and radiation efficiency were degraded. Finally, a via-free ZOR antenna had an advantage of compactness even though its fractional bandwidth is narrow and its radiation efficiency is poor, compared with thoses of mushroom ZOR antenna with via.

The size distributions of smoke particles from fire are prerequisite for the studies on fire detection and adverse health effects. Above the flame of the fire, coagulation dominates and the smoke particles grow from 1 to 50 nm up to 100 to 3,000 nm, sizes ranging from the free-molecular regime to the continuum regime. The characteristics of the agglomeration of the smoke particles are well known, independently for each of the free-molecular and continuum regimes. However, there are not many systematic studies in the entire regime by the complexity of the mechanisms. The purpose of this work is to find the characteristics of the development of the size distribution of smoke particles by agglomeration in the entire size range covering the free-molecular regime, via transition regime, to the near-continuum and continuum regime for each variation of parameters such as fractal dimension, primary particle size and dimensionless coagulation time. In this work, the dynamic equation for the discrete-size spectrum of the particles was solved using a nodal method based on the modification of a sectional method. In the calculation, the collision frequency function for the entire regime, which is derived by using the concept of collision volume and general enhancement function, was applied. The self-preserving size distribution for the entire regime is compared with the ones for the free-molecular or continuum regimes for each variation of the parameters.

In this present paper, a new two dimensional (2D) and quasi three dimensional (quasi-3D) nonlocal shear deformation theories are formulated for free vibration analysis of size-dependent functionally graded (FG) nanoplates. The developed theories is based on new description of displacement field which includes undetermined integral terms, the issues in using this new proposition are to reduce the number of unknowns and governing equations and exploring the effects of both thickness stretching and size-dependency on free vibration analysis of functionally graded (FG) nanoplates. The nonlocal elasticity theory of Eringen is adopted to study the size effects of FG nanoplates. Governing equations are derived from Hamilton's principle. By using Navier's method, analytical solutions for free vibration analysis are obtained through the results of eigenvalue problem. Several numerical examples are presented and compared with those predicted by other theories, to demonstrate the accuracy and efficiency of developed theories and to investigate the size effects on predicting fundamental frequencies of size-dependent functionally graded (FG) nanoplates.

Purpose - This study analyzes the effect of internationalization represented as exporting on firm performance on the subject of SMEs operating in Masan Free Trade Zone which has shown poor performance recently despite its status as the oldest and largest free trade zone in Korea. We also analyze the effect of firm size on firm performance, and the moderating role of firm size in relation to internationalization and firm performance. Design/methodology - This study uses multiple regression models for unbalanced panel data as the empirical tools for the estimation of the effect that internationalization has on firm performance (ROA or ROS). Our sample consists of 91 manufacturing SMEs among all 110 companies located in Masan Free Trade Zone as of 2017. Findings - The degree of internationalization has a negative impact on firm performance. However, firm size turns out to have a positive effect and play a positive moderating role in the relation to internationalization and firm performance. This seems to be because most tenant companies operating in Masan Free Trade Zone are small firms whose costs of internationalization may exceed the benefits. Empirical results also show that longer CEO tenure has a greater negative effect on firm performance. Originality/value - The originality/value of this paper can be found in 3 aspects. First, we conducted an empirical analysis on the relationship between the internationalization and firm performance of SMEs in a specific region, namely, Masan Free Trade Zone. Second, while most previous studies focused on listed medium companies, most of the sample of this study are small and medium non-listed enterprises. Third, it is witnessed that firm size has a positive moderating effect on the relation between internationalization and firm performance.
