The aim of this essay is to illustrate Sunjung Manhwa in the 1970s which has been alienated in comics studies. This essay analyses the articles and the serial comics in Schoolgirl, the magazine in the 1970s, and examines the ideal representations of the girls at that time. Sunjung Manhwa is really different between the 1960s and 1970s. It cannot be explained on this gap just by analyzing Sunjung Manhwa in book form alone. Even though the censorship on comics was the element that has hampered the development of comics as a whole, the slumps of Sunjung Manhwa in the 1970s were very excessive compared to other comics genres. This article can gain the answers to the reason of the changes of Sunjung Manhwa by studying the magazines which was the main mass media aimed at girls with Sunjung Manhwa. While the articles in magazines show the editing direction and its characteristics, they reflect the values and ideologies at that time. The same is true for the comics in the magazines. Especially, the comics in the magazines was relatively free from the censorship. This essay examined how the articles and the comics in the girls' magazine in the 1970s represented the images of girls at the time by focusing on feature articles and comics in the magazine, Schoolgirl. This article explored Um, Hee-Ja's Blue Zone and Bang, Young-Jin's Mini March among a full-length serial comics in the magazine, Schoolgirl. Both Blue Zone and Mini March reveal the images of an ideal girl that has been emphasized by the articles in Schoolgirl. Blue Zone draws the appearances of an earnest and obedient daughter, and Mini March represents the figures of a cheerful and bright girl. Through this study, it can be recognized that the magazines in the 1970s highly appraised girls who are obedient to a given society and serve to a harmonious family as ideal ones, and it might be guessed that the ideal images of girls that was characterized ceaselessly by the magazines were the standard of the censorship on comics and its creativity and had also a huge impact on the contents and the expressions of a great deal of works. The 1970s was the times when its importance has been lost in the history of the comics studies by the censorship on the comics and the monopoly of "Hapdong(합동) publisher." The limits of expression in terms of censorship were awfully distinct, so its result was few of good works in quality, and there are still many blanks in the study on 1970s' comics. This study has a meaning which fills up a blank in the comics studies.

Using a linear loss function, this paper considers the one-sided testing problem for the exponential distribution via the empirical Bayes(EB) approach. Based on right censored data, we propose an EB test for the exponential parameter and obtain its convergence rate and asymptotic optimality, firstly, under the condition that the censoring distribution is known and secondly, that it is unknown.

Some rank tests for comparing r treatments against ordered alternatives are proposed when some of data are randomly cemsored, which are the weighted logrank tests based on pairwise-ranking scheme. The covariances of the proposed test statistics are explicitly obtained from the results of the counting process theory and the test procedures are illustrated by a numerical example. Simulation studies are also performed for comparing with the other well-known tests.

To test the equality of survival distributions in the presence of arbitrary right censorship, the choice of weights which are functions of the number of individuals at risk at the time of each death is very important in increasing the power of the test. In this paper a weight by probit scale is derived and the efficiencies relative to the other weight's are also investigated.

The objective of this study is to investigate the problem of goodness of fit testing based on nonparametric function estimation techniques for the random censorship model. The small and large sample properties of the proposed test, $E_{mn}$, were investigated and it is shown that under the proportional hazard model $E_{mn}$ has higher power compared to the powers of the Kolmogorov -Smirnov, Kuiper, Cramer-von Mises, and analogue of the Cramer-von Mises type test statistic.

In this paper we considered the problem of estimating the bivariate survival distribution of the random vector (X, Y) when Y may be subject to random censoring but X is always uncensored. Adapting conditional Koziol-Green model, simplified estimator for bivariate survival function is proposed. We perform simulation to compare the proposed estimator with popular estimators and discussed the performance of it.

In this paper, we consider two components system which have bivariate weibull model with bivariate random censored data. We proposed large sample test for independence based on maximum likelihood estimator and relative frequency estimator, respectively. Also we derive asymptotic properties for the large sample tests and present a numerical study.

In this paper, we consider two components system which have bivariate weibull model with bivariate type I censored data. We proposed maximum likelihood estimator and relative frequency estimator for the reliability of series system. Also, we construct approximate confidence intervals for the reliability based on the two proposed estimators. And we present a numerical study.

In this paper, we demonstrate the more accurate confidence intervals for median survival time under the simple proportional hazard model of Koziol and Green (1976) via the Edgeworth expansion for the distribution of the studentized ACL estimator derived in Jeong (2000). The numerical results show that the intervals, so-called test-based and reflect intervals (Slud et al., 1984), outperform normal approximating method in the small sample sizes and/or heavy censoring.
