The development of webtoon accelerated with development of smart devices. It became a daily life to enjoy digital contents such as webtoon using smartphones on the streets and subways, not just for the novelty of the new generation. With the advent of smart devices, the webtoon market has grown rapidly and webtoons of various themes and genres are pouring out. The growth of webtoon market is a good opportunity for artists, but competition is getting worse and it is difficult to satisfy readers with low quality. In order to create webtoon that can satisfy the readers, the artists are considered as important homework that can show the interesting story and show it effectively. In this study, I tried to prove that the method of directing using shot among the elements of animation can be utilized for directing webtoon effectively. In order to explain this, I have tried to explain the characteristics of webtoon and its relation with animation, and I chose the most important example of webtoon, 'Ko Soo(Ryu Ki woon, Moon jeong hu, 2015)', which has been popularized with successful storytelling and directing, and described character shot and time transition shot.

As a background for qualitative research, the concept of bricolage is very common in the North America. As a movement of art area, because, it has characteristics of criticality and existence which is very close to the definitions of qualitative research. However, regardless of recent rapid wide-spread of qualitative research with the world trend of research methodology, it is very unusual that scholars are rarely discussing on the concept of bricolage in South Korea. In literature review, scholars conceptualize bricolage in literature, art, and so on except qualitative research field. Thus, I realize that it is necessary to discuss the concept of bricolage in qualitative research. Through it, scholars will understand more about the definition of qualitative research. Accordingly, I try to prove the thesis 'qualitative research is bricolage' in this article. In conclusion, scholars commonly define qualitative research to involve the meanings of 'reflection', 'understanding', 'deconstruction', and 'reconstruction' and illustrate also the concepts of bricolage in a praxis of interpretation and understanding with getting together of rigorousness, complexity, and criticality. I realize that these notions are very close to each other in this study.

LDD structure is widely accepted in fabricating short channel MOSFETs due to reduced short channel effect originated form lower drain edge electric field. However, modeling of the LDD device is troublesome because the analysis methods of LDD region known are either too complicated or inaccurate. To solve the problem, this paper presents a nonlinear resistance model for the LDD region based on teh fact that the electron mobility changes with positive gate bias because accumulation layer of electrons is formed at the surface of the LDD region. To prove the usefulness of the model, single source/drain and LDD nMOSFETs were fabricated with 0.35$\mu$m CMOS technolgoy. For the fabricated devices we have measured I$_{ds}$-V$_{gs}$ characteristics and compare them to the modeling resutls. First of all, we calculated channel and LDD region mobility from I$_{ds}$-V$_{gs}$ characteristics of 1050$\AA$ sidewall, 5$\mu$m channel length LDD NMOSFET. Then we MOSFET and found good agreement with experiments. Next, we use calculated channel and LDD region mobility to model I$_{ds}$-V$_{gs}$ characteristics of LDD mMOSFET with 1400 and 1750$\AA$ sidewall and 5$\mu$m channel length and obtained good agreement with experiment. The single source/drain device characteristic modeling results indicates that the cahnnel mobility obtained form our model in LDD device is accurate. In the meantime, we found that the LDD region mobility is governed by phonon and surface roughness scattering from electric field dependence of the mobility. The proposed model is useful in device and circuit simulation because it can model LDD device successfully even though it is mathematically simple.

On the basis of Sternberg's theory of mental self-government, this examined the difference in thinking style between gifted science students and non-gifted students, and their earth science concepts by the different types of thinking styles. The subjects were consisted of 120 students from the Busan Science Academy and 122 students from two general high schools in Busan, Korea. All participants responded to the Thinking Styles Inventory which is a self-report test consisting of 65 items, and essay questions for examining the students' earth science concepts. The results are as follows. First, the gifted science students prefer legislative, judical, anarchic, global, and liberal styles, where non-gifted students prefer executive, oligarchic, and conservative styles. Second, Type I thinking style group prove to have more complex concepts in relation to the geological and astronomical areas than those of the Type II thinking style group in both of the gifted and non-gifted students. This indicates that Type I thinking style students use a deep learning approach where Type II thinking style students use a surface learning approach.

With the widespread use of the obstetrical ultrasound, identification of a fetal suprarenal mass becomes more common. Most of these masses prove to be congenital neuroblastomas (CNB) postnatally. However, the diagnosis is often confused with other benign lesions and the post-natal management remains controversial. The medical records of 13 patients that underwent primary surgical excision for an antenatally detected adrenal CNB, between January 1995 and April 2009, were reviewed retrospectively. The clinical, radiological, surgical, and pathological data on the suprarenal mass were collected. Staging evaluation was performed after histological confirmation of the CNB. Most of the CNBs were stage I (N=11), with 1 stage IV and 1 stage IV-S. Four patients (3 stage I and 1 stage IV-S) had N-myc gene amplification. The stage I patients were cured by surgery alone, and stage IV patients underwent 9 cycles of adjuvant chemotherapy and currently have no evidence of disease after 39 months of follow-up. The patient with stage IV-S is currently receiving chemotherapy. There were no post-operative complications. For early diagnosis and treatment, surgical excision should be considered as the primary therapy for an adrenal CNB detected before birth. The surgery can be safely performed during the neonatal period and provides a cure in most cases. Surgical diagnosis and treatment of CNB is recommended in neonatal period.

Digital games are generating various types of virtual landscape and the importance of virtual landscape has been arises. However, there has not been any research done how to design the virtual landscape. To establish virtual landscape design methodology, establishing the classification system and suggesting the representative type of virtual landscape is needed. With this research, I collected the classification standard and established five standards; story, cooperation, interaction level, dimensions and shape of the space. With that system, I classified digital game and could prove the effectiveness. Also by classifying cases through 20 years of timeline, I could come out with three representative types. This result will work as a reference to the future research; establishing design methodology on virtual landscape.

Objectives : Shanghanlon is based on the Hwangjenaegyeong(黃帝內經)'s theory. Therefore, the contents of the Naegyeong can interpret Shanghanlon's provision, Chengwuji(成無己) followed the same way. Therefore, I studied the relationship between the symptom of Shanghanlon and the defensive Gi(衛氣), I try to prove that the Naegyeong is the theoretical basis of Shanghanlon. Methods : Naegyeong explains that defensive Gi protects the outer parts of the body, and runs the outer parts of the body. So I will explain the spontaneous sweating(自汗) aversion to cold(惡寒) pain(痛症) fever(發熱) difficulty of urination(小便不利) using the function of defensive Gi. Results & Conclusions : The defensive Gi and the nutrient Gi(營氣) run together, if the defensive Gi is weak, can not protect the nutrient Gi. If the defensive Gi does not perform the function of inducing astringency(固攝), the symptom of spontaneous sweating appears. If aversion to cold is caused by the weak of defensive Gi, we use the treatment of warming the Yang(溫陽). If aversion to cold is caused by the defensive Gi can not run, we use the treatment of activating the Yang(通陽). If the Gi and Blood(氣血) is not feeding properly, the pain occurs. In this case, we use the treatment of activating the Yang(通陽). The fever is caused by the stagnation of defensive Gi. If the defensive Gi is weak, the symptom of difficulty of urination appears.

Let ${\Delta}$ be a simplicial complex, $I_{\Delta}$ its Stanley-Reisner ideal and $K[{\Delta}]$ its Stanley-Reisner ring over a field K. Assume that ${\Gamma}(R)$ denotes the zero-divisor graph of a commutative ring R. Here, first we present a condition on two reduced Noetherian rings R and R', equivalent to ${\Gamma}(R){\cong}{\Gamma}(R{^{\prime}})$. In particular, we show that ${\Gamma}(K[{\Delta}]){\cong}{\Gamma}(K^{\prime}[{\Delta}^{\prime}])$ if and only if ${\mid}Ass(I_{\Delta}){\mid}={\mid}Ass(I_{{{\Delta}^{\prime}}}){\mid}$ and either ${\mid}K{\mid}$, ${\mid}K^{\prime}{\mid}{\leq}{\aleph}_0$ or ${\mid}K{\mid}={\mid}K^{\prime}{\mid}$. This shows that ${\Gamma}(K[{\Delta}])$ contains little information about $K[{\Delta}]$. Then, we define the squarefree zero-divisor graph of $K[{\Delta}]$, denoted by ${\Gamma}_{sf}(K[{\Delta}])$, and prove that ${\Gamma}_{sf}(K[{\Delta}){\cong}{\Gamma}_{sf}(K[{\Delta}^{\prime}])$ if and only if $K[{\Delta}]{\cong}K[{\Delta}^{\prime}]$. Moreover, we show how to find dim $K[{\Delta}]$ and ${\mid}Ass(K[{\Delta}]){\mid}$ from ${\Gamma}_{sf}(K[{\Delta}])$.

A simple measuring device is proposed, and its performance is examined in an adsorption process separating a gas mixture. The sensor is made of a quartz crystal resonator and solid adsorbent to detect the target component. Micro-particle carbon cryogel(MCC) is utilized as the adsorbent, and the gas mixture of air and i-butane are separated in a column containing bamboo activated carbon. Two devices are placed at the inlet and outlet of the column. The measurements are compared with those of GC outcome to prove the measurements are effective. The experimentally proved system is simple and capable to be implemented in an in-line system with on-line measurement.

In the field of finance, Trading System of Securities is a very vulnerable application when it faces any small problems just for one minute. Since Trading System changes its environment from mainframes to client/server, its safety becomes the most important factor. Even though most If systems are configured by general guidelines currently, Trading System is an exception that it is configured by specific and rather ad hoc guidelines in order to ensure its safe management. In this thesis, I will prove the validity of specific and ad hoc configuration in the environment of Trading Systems where I use both XA interface system and Non-XA interface to configure its system based on 3-Tier Client/server computing environment through middleware, TP-Monitor, in the X/Open DTP Model. In order to validate the Trading System, I will compare and analyze the error of data of an order and ability to restore using both XA and Non-XA interfaces while testing take-over scenario on the assumption of the system's failure.
