This study used the results of the 2022 national survey of forest welfare facilities and space users conducted in the Republic of Korea to identify the associations and combination patterns among use of forest welfare facilities and various user characteristics. In addition, a correspondence analysis-namely, a categorical data analysis-was performed regarding four facilities: National Natural Recreation Forest, National Soopchewon, National Forest Trail, and National Healing Forest. The cross-analysis revealed highly significant differences (p < .001) in the age, household income per month, means of transportation, companion type, path to information acquisition, and purpose of visit among the users of forest welfare facilities. Moreover, the results of the correspondence analysis demonstrated that users of National Soopchewon and National Healing Forest were distinguished from users of the other forest welfare facilities based on demographic characteristics such as age and household income per month. In addition, the means of transportation of National Forest Trail users differed from that of users of the other forest welfare facilities. Moreover, users of National Soopchewon were associated with the type of public group visit, acquisition of information from the websites of related institutions and facilities and via online portals, and the purpose of participating in education and experiencing education programs. Therefore, the companion type, path to information acquisition, and purpose of visit on the part of users of National Soopchewon could be differentiated from those of users of other forest welfare facilities. The findings of this study revealed the associations and combinations among forest welfare facilities and the characteristics of users of such facilities, with the scope of utilization of the forest welfare facility user data being expanded via correspondence analysis.

최근 인터넷의 가용성을 위협하는 대형 침해사고는 줄어들고 있으나 스팸, 피싱, 금전적 이익을 위한 분산서비스거부공격 등 악성행위의 양상은 더욱 정교하고 교묘해지고 있다. 이러한 변화는 인터넷 이용에 수반되는 잠재적인 위협을 크게 증가시켰으며 악성행위자와 이에 대응하는 보안전문가 간의 비대칭성을 크게 증가시키고 있다. 네트워크 포렌식은 보호하고자 하는 자산에 대한 직접적인 위협과 잠재 위협을 정확히 산정 할 수 있는 수단을 제공하여 기존의 대응 방법에서 발생하는 비대칭성을 상쇄시킬 수 있는 수단을 제공해준다. 본 논문에서는 네트워크 포렌식의 동향과 기술에 대해 설명하고 이를 이용한 분석 사례를 통해 네트워크 포렌식의 효용을 설명하였다.

In order to effectively communicate the fragrances of commercial perfumes to consumers, it is important to apply congruent colors to their bottles and packaging. This research investigated the cross-modal associations between colors and fragrances through two experiments. In the first experiment, bottle colors of more than 200 popular perfumes in the market were analyzed. Distinguishable color design patterns of the bottles were revealed in accordance with their fragrance types. The second experiment expanded the use of color-odor matching task to a test population of Korean participants. Participants selected colors evoked by fragrances of three test perfumes in a blind setting. These three perfumes had characteristic hues and their associated hues were similar with the real colors of their bottles. In addition, there were significant variations in color tone across fragrance notes, viz. the top notes, middle notes, and base notes. The results of the two experiments suggest the existence of robust cross-modal associations between particular colors and fragrances in commercial perfumery.

이중편파 강우레이더는 차등반사도, 차등위상차, 비차등위상차 등 다양한 변수를 관측하여 호우의 공간적 규모, 호우를 구성하는 강수입자, 호우의 이동방향 등 종합적인 강우 정보를 제공한다. 이러한 이중편파레이더를 이용하면 단일편파레이더에 비해 보다 정량적인 강수 추정이 가능하다. 일반적으로 이중편파 강우레이더의 강우추정 관계식은 DSD 및 강우입자 모형을 기반으로 물리적으로 유도된다. 그러나 DSD는 호우 사상에 따라 그 양상이 다르며, 동일 호우 사상 내에서도 시공간적으로 변화가 크다. 이러한 DSD에 내포된 변동성은 결과적으로 레이더 강우에 큰 불확실성을 유발하게 된다. 이에 본 연구에서는 확률대응법을 이용하여 이중편파레이더의 강우추정 관계식을 추정하는 기법을 개발하고자 한다. 확률대응법은 실시간으로 강우추정 관계식의 매개변수를 추정하는 기법으로 단일편파레이더의 Z-R 관계식에 적용된 바 있다. 이러한 확률대응법을 이용하면 시공간적으로 변하는 DSD 등 호우사상의 개별적인 특징을 반영하여 호우사상별 강우추정 관계식의 매개변수를 실시간으로 결정할 수 있다. 따라서 본 연구에서는 이중편파레이더의 강우추정 관계식 중 R(KDP, Zdr), R(Zh, Zdr) 관계식을 위주로 매개변수를 이변량 확률대응법을 통해 추정하고, 기존의 강우추정 알고리즘 및 관계식의 레이더 강우 추정 결과와 비교를 통해 적용성을 평가하였다.

The purpose of this study was to study what effect providing the patient with preparatory concrete information had on the state anxiety depending on coping styles of patients undergoing cardiac catheterization. State Anxiety scores for 32 patients who had cardiac catheterization were examined after information was provided about the test using an audio tape. The state anxiety of patients who had a high trait anxiety level was compared to that of those who had a low trait anxiety level. The state anxiety of those who had a monitor type were compared to those of patients who had blunter type. The Trait and State Anxiety Scale of Spielberger, Miller's Behavioral Style Scale, and Krantz's Health Opinion Survey and Visual Analog Scale (Ⅰ, Ⅱ) were used. Findings were as follows : 1. Among the demographic characteristics, gender difference of the patients was significantly different for the trait anxiety level. Female patients had higher trait anxiety level than male patients. 2. Analysis of state anxiety scores indicated that the mean score of the state anxiety prior to the test was higher than the mean score of the state anxiety examined after the test. The difference was statistically significant. 3. Among the patients, 14 patients (43. 7%) used monitor type, while 18 patients (56. 3%) used blunter type. The means of preference for information measured on the Krantz' subscale was 2. 45. 4. The study results indicate that the state anxiety level of those who had a low trait anxiety level was lower than that of those who had a high trait anxiety level. 5. State anxiety levels depending upon the kind of coping style which patients used during the test were not significantly different. This study did not identify the influence of preparatory concrete information on the state anxiety depending on coping styles, and there fore a quasi-experimental study using a large sample according to different types of information, and the amount of information, coping styles is recommended.

This study was aim to provide rheumatoid arthritis patients the basic data of development of nursing intervention to help psychosocial adaptation of rheumatoid arthritis patients as exploring the relationship among causal perception, coping pattern, psychosocial adaptation of rheumatoid arthritis. As the results of this study the mean score of causal perception of the subjects was 3.37. The score of the internal-unstable was the highest. which was followed by extra-stable, internal factor, internal-stable, external factor and external-unstable in order among the factor of causal perception. The mean score of coping pattern was 2.64. The type of coping patterns the score of the receptive coping was the highest, which was followed by wishful coping active coping and negative coping in order among the type of coping pattern. The mean score of psychosocial adaptation was 3.28. The subconcept of psychosocial adaptation the score for personal relationship was the highest, which was followed by role function and mental state in order among the psychosocial adaptation. The analysis of the relation among causal perception, coping pattern and psychosocial adaptation showed significant negative correlation between causal perception and psychosocial adaptation(r=-0.3219, P=0.002). The analysis of the relation between the type of coping pattern and psychosocial adaptation showed significant negative correlation between psychosocial adaptation and active coping(r=-0.3210, P=0.002), negative coping(r=-0.2296, P=0.032). Only causal perception(-.36) and period of illness(-.26) effected on the psychosocial adaptation were shown to the negative direction significantly. The psychosocial adaptation was explained the 17% by these two variables. Based on this study results the factor of causal perception and the type of coping pattern of rheumatoid arthritis were shown significant relations between psychosocial adaptation. We suggests that nurses in practice apply to assessing the factor of causal perception of individuals illness and the type of coping patterns when nursing interventions in rheumatoid arthritis patients.

There are many institutions, organizations, and sites related to responding to infectious diseases, but as the pandemic situation such as COVID-19 continues for years, there are many changes in the initial and current aspects, and accordingly, policies and response systems are evolving. As a result, regional gaps arise, and various problems are scattered due to trust, distrust, and implementation of policies. Therefore, in the process of analyzing social data including information transmission, Twitter data, one of the major social media platforms containing inaccurate information from unknown sources, was developed to prevent facts in advance. Based on social data, which is unstructured data, an algorithm that can automatically detect infectious disease threats is developed to create an objective basis for responding to the infectious disease crisis to solidify international competitiveness in related fields.

This study investigated the mapping errors induced in learning the concept of reaction rate with analogies, and compared these mapping errors by the analogy presentation types. Tenth graders (N=418) at a high school were assigned to the four groups by the target concepts and the analogy presentation types. The target concepts were 'concentration and reaction rate' and 'temperature and reaction rate'. In presenting analogy, the verbal and the verbal/pictorial analogs were used. After the students learned one of the analogs, a mapping test was administered. From the analysis, eight types of mapping errors were identified: overmapping, artificial mapping, failure to map, rash mapping, mismapping, mapping of a superficial feature, retention of a base feature, and impossible mapping. According to the analogy presentation types and the features of the target concepts, there were some differences in the frequencies of mapping errors. Educational implications of these findings are discussed.
