Objectives The study was designed to find out the relationships between short stature and low weight among children and teenagers. Methods This research was performed in 21 children and teenagers from August 2006 to June 2007. We measured height, weight, body mass index, obesity rare, bone age, and HTMA. Moreover, we analyzed correlation with height, weight, mineral concentrations and ratios obtained from HTMA. Results There were significant correlations between HTMA and short stature and low weight. 1. Most subjects(76%) had slow metabolic types. 2. Ca, Mg, Zn, Ca/P, and Cr had significant differences between high bone age group and high chronological age group. 3. Fe/Cu had significant differences between a group that recent height is more smaller than inherited height and a group that recent height is more taller than inherited height. 4. Ca, Mg, Ca/P had significant differences between a low weight group and a normal weight group classified by obesity rate. Conclusions Children and teenagers with short stature and low weight have specific mineral characters.

Objective : The purpose of this study was to analyze the origin of Meretrix. Method : Bibliographies about Meretrix were examined focusing on the origin. Based on this analysis, the list and characteristics of the origin-mineral were presented. Results : Based on the Meretrix, the Korean and foreign literature were investigated to make a list, and the process of changing the origin was organized in chronological order. Based on these results, the shape of the currently cultivated or distributed drugs, the status of the distributed drugs and the status of the distributed products were summarized. In addition, the results of summarizing the adverse effects and sensitivities of the efficacy and prestige are as follows: 1. The origin of the Meretrix corresponded to the fall of the mollusks Merethrix metrix L. and Cyclina sinensis Gmelin, which are mollusks belonging to the reference family Veneridae. Their Herbal name is CONCHA CYCLINAE SEU MERETRICIS and they have therapeutic effects on cough, asthma, thirsty and chest heavies. 2. Munhap (文蛤) is a different name of GALLA CHINENSIS. It has therapeutic effects on various skin diseases. Conclusions : The Meretrix means two herbs. The first one is CONCHA CYCLINAE SEU MERETRICIS, the other is GALLA CHINENSIS. They should be used separately according to their clinical use.

Purposes: Speech acceptability means the subjective judgement of listeners regarding the naturalness and normality of the speech. The purpose of this study was to determine the predicting variables for speech acceptabilities of children with cochlear implants. Methods: Twenty seven children with CI participated. They had profound pre-lingual hearing loss without any additional disabilities. The mean of chronological ages was 8;9, and mean of age of implantation was 2;11. Speech samples of reading and spontaneous speech were recorded separately. Twenty college students who were not familiar to the speech of deaf children evaluated the speech acceptabilities using visual analog scale. 1 segmental (articulation) and 6 suprasegmental features (pitch, loudness, quality, resonance, intonation, and speaking rate) of speech were perceptually evaluated by 3 SLPs. Correlation and multiple regression analysis were performed to evaluate the predicting variables. Results: The means of speech acceptability for reading and spontaneous speech were 73.47 and 71.96, respectively. Speech acceptability of reading was predicated by the severity of intonation and articulation. Speech acceptability of spontaneous speech was predicated by the severity of intonation and loudness. Discussion and conclusion: Severity of intonation was the most effective variable to predict the speech acceptabilities of both reading and spontaneous speech. A further study would be necessary to generalize the result and to apply this result to intervention in clinical settings.

Species like insects and fishes have, in many cases, non-overlapping time intervals of one generation and their descendant one. So the population dynamics of such species can be formulated as discrete models. In this paper various discrete population models are introduced in chronological order. The author's investigation starts with the Malthusian model suggested in 1798, and continues through Verhulst model(the discrete logistic model), Ricker model, the Beverton-Holt stock-recruitment model, Shep-herd model, Hassell model and Sigmoid type Beverton-Holt model. We discuss the mathematical and practical significance of each model and analyze its properties. Also the stability properties of stationary solutions of the models are studied analytically and illustratively using GSP, a computer software. The visual outputs generated by GSP are compared with the analytical stability results.

Animal bones excavated with earthenware from the shell mound at the Jeju Jongdali 1819 archeological site, where three consecutive chronological layers covering the Neolithic (B.C. 15C-B.C. 10C), early Tamra, and late Tamra periods have been identified, were morphologically classified. The majority of the bones from all three periods were broken or split. The major fauna of the mammalian bones in all periods were Cervus spp., Sus scrofa, and Bos taurus. In the early and late Tamra periods, bones of small animals including Mustela sibirica coreana, Meles meles, Rodentia, and Aves were also found in small number. The excavated bones were from all parts of the animal bodies, including head, trunk, forelimb, and hindlimb. Collectively, these findings suggest that the major fauna from the Neolithic to late Tamra periods consisted of Cervus spp., Sus scrofa, and Bos taurus and that the fauna was dissected and carried to the shell mound site after hunting. Information from the bone remains in the shell mound are useful data for study of the wildlife and domestic animals living during the prehistoric period of Jeju Island.

The study focused on residents' preference for planning components according to preferred size of high-rise condominiums. After being examined not only a brief chronological review of spatial composition and planning components in high-rise condominiums but also residents' attitudes toward and preference for current planning components, this research developed a wide range of planning components included in the questionnaire. The main survey was designed to find out the needs of residents for planning components in relation to high-rise condominiums. Descriptive and factor analysis were utilized to find out the residents' different preference for planning components. The findings of this study showed that residents were very aware of healthy housing, environmental friendly housing and digitally equipped housing, and their preference was different according to preferred size of condominium housing. In other words, residents preferring condominium housing with 99m$^2$ or smaller considered features of safety and healthy housing as important, those with between 102.3m$^2$ to 115.5m$^2$ recognized experiential space, and those with 118.8m$^2$ or larger regarded features of housing management and storage as important. It is suggested that the needs and wants of residents for housing have been various to be customized.

The purpose of this study was to increase the current understanding of the acoustic characteristics of voices with advancing age. The relationship between age-related changes in body physiology and certain acoustic characteristics of voice was studied in a sample of 80 men representing four chronological age groupings (20-29, 50-59, 60-69, 70-79) who were all of good physical condition. Each subject was asked to phonate the vowel /a/, /i/, and /u/ for as long as possible at comfortable frequency and intensity level and read the sentence. A promising voice analysis program (Multi-Dimensional Voice $Program^{TM}$) was used to measure the fundamental frequency ($f_0$), jitter, shimmer, $f_0$ variation, peak-amplitude variation, smoothed pitch perturbation quotient, smoothed amplitude perturbation quotient, soft phonation index, $f_0$-tremor intensity index, amplitude tremor intensity index, and noise-to-harmonics ratio from the samples.

This study analyzed the changes in explanatory power of the modified Jones model(1995) for estimating the amount of accruals for Korean Stock Market listed companies from 1990 to 2019. We hypothesized that if the properties of financial variables used in the existing model change over time or change in discretionary ratios, the model's explanatory power will change. As the result of regression models, I found that the explanatory power of the modified Jones model(1995) gradually declined over time. The results may be derived from the increase in accruals itself and the changes in the distribution of variables contained in the model. The results of this research's chronological approach are expected to give important implications to both academic researchers and accounting information users.
