The co-occurrence of congenital central hypoventilation syndrome (CCHS) and Hirschsprung's disease (HD) is termed Haddad syndrome, which is an extremely rare discorder. It was reported first by Haddad in 1978 and there are approximately 60 cases reported in the worldwide literature. Recent studies described that congenital central hypoventilation syndrome had deep relation to the mutation of the PHOX2B gene in its diagnosis and phenotype. This article presents a case report: Dental treatment of a 3-year-old male patient with Haddad syndrome under outpatient general anesthesia. The special considerations of dental care, especially caries theatment of the patient with Haddad syndrome are discussed.

Adrenoleukodystrophy (ALD) is a rare, inherited disorder that leads to progressive brain damage and failure of the adrenal glands. It is passed down from parents to their children as an X-linked genetic trait. Therefore, it affects primarily males especially under the age of 10. People with ALD have excessive accumulation of very long chain fatty acids (VLCFAs) in their brain because they do not have the enzyme which break down these fatty acids. Special method for treatment of ALD is not available. Eating a diet low in VLCFAs and taking special oils, called Lorenzo’s oil, can lower the blood levels of VLCFAs. But this oil cannot stop the destruction of nerve cell. This article presents a case report: Dental treatment of a 11-year-old male patient with ALD under general anesthesia. Careful management must be required during treatment procedure because of difficulty in cooperation, seizure disorders, gastroesophageal reflux, pulmonary aspiration and airway complications.

When designing a ship, ergonomic considerations are crucial when minimizing a navigator's fatigue due to the burden of work, and to appropriately operate the navigational equipment for each given situation by helping the operator to understand the surroundings as well as the physical functions of the ship. However, insufficient consideration of ergonomic elements in the actual design of ship Bridges is lowering the performance of safe navigation and allows for the possibility of operation or readout errors. Consequently, these errors lead to an increase in maritime accidents. Therefore, this study conducted a usability evaluation on the importance of and the usage frequency of navigational equipment, their influence on actual navigation, and the possibility of error upon operation or readout between training ship officers, to derive an optimized layout that includes the consideration of ergonomic factors for on-Bridge navigational equipment, which are currently arranged differently according to their type or size. The optimized layout of on-Bridge navigational equipment was carried out based on the evaluation results, using the Lingo program. Through the process of optimization, revised layouts of on-Bridge navigational equipments(control and display device) were suggested, considering emergency situations(ship collision, stranding, fire and explosion, sinking, etc.) during navigation.

朝鮮世宗期1·2차 通信使와 對日政策의 기조

장준혁(Jang, Jun Hyuk) 역사실학회 2019 역사와실학 Vol.69 No.-

조선은 고려 말부터 계속된 왜구의 침입을 극복하고 안정적인 對日關係를 형성할 필요가 있었다. 이를 위해 조선은 일본에 사신을 파견하거나 對馬島를 정벌하는 등 다방면으로 노력하였다. 그 중에서도 對日政策의 정비를 통해 왜구들을 왜인으로 전환시키고자 한것은 태종시기부터였다. 도서·문인제도를 시행하여 왜구들을 통교왜인으로 전환시키려 노력했으며, 이는 세종시기로 이어지게 된다. 세종은 태종의 정책들을 계승하여 對日政策에 나서게 된다. 하지만 통교왜인은 세종시기에 와서 그 숫자가 더욱 증가하였다. 조선의 경제적 부담은 계속 커져갔고, 세종은 우선적으로 통교왜인들에게 제공되는 과도한 혜택들을 개선해 나갔다. 하지만 조선 경제 부담의 근본적인 원인은 도항해오는 왜인들의 숫자가 많은 것에 있었다. 세종은 신중하게 왜인들을 통제할 필요가 있었으며, 그러기 위해서는 내조해오는 九州 및 對馬島에 대한 정보가 필요했다. 이로 인해 처음으로 조선통신사가 일본에 파견되었다. 1428년(세종 10) 1차 통신사의 파견 이후 얻은 정보를 바탕으로 세종은 본격적으로 통교왜인들의 통제에 나섰다. 북방문제로 발생한 두 차례의 파저강정벌 이후에도 세종은 새로운 정책들을 통해 적극적으로 왜인들을 통제해 나갔다. 하지만 九州는 계속해서 內戰상태에 있었고, 세종은 이러한 상황에서 1439년(세종 21) 2차 통신사를 파견하였다. 그리고 이 시기를 전후해 조선과 對馬島는 몇 차례의 조약이 성사되었고, 1440년(세종 22)인 경신년을 기점으로 對馬島와 체결한 조약들이 법적으로 효력을 발휘하기 시작했다. 그리고 2차 통신사가 복귀한 이후에는 孤草島에서 왜인들의 어업활동에 대해서 논의가 있었다. 이 시기는 조선 북방의 야인들의 명의 황제의 허락으로 다시 세력을 합치게 된 상황이었다. 두 차례 정벌을 통해 안정시킨 북방변경이 또 다시 위협받는 상황에 놓이게 된 것이다. 세종은 상대적으로 중요한 북방정책에 집중하기 위해 對日關係를 확실하게 안정시키고자 했다. 그 과정에서 對馬島主의 위상을 강화시켜 왜인들을 통제하고자 했는데, 島主중심의 도서·문인체제 및 왜인들의 孤草島 어업활동은 이러한 흐름에서 등장한 것이었다. 조선은 對馬島를 통해 우선적으로 왜인들을 통제하면서, 이를 바탕으로 북방정책에 집중할 수 있었다. 이 시기 조선 북방정책의 흐름은 1443년(세종 25)을 전후로 완성되는 四郡六鎭으로 이어지게 된다. 한편으로는 계속된 對日政策의 흐름 역시 1443년의 癸亥約條 체결로 이어지게 되며, 조선은 남북의 적절한 대외정책을 통해 의미있는 결실을 맺게 된 것이다. Joseon needed to squash invasion of Waegu which had been frequent since late Goryeo and form stable relations with Japan. To achieve these, they tried various tactics like sending an envoy and conquering Tsushima, ect. Especially, a new attempt had been tried in King Taejong’s reign; changing social position of Waegu to Waein through a reorganization of relations between Joseon and Japan. King Sejong inherited the policies of King Taejong. However, as the number of Japanese traders kept increasing in King Sejong’s reign, he sorted out the benefits offered to Japanese trader first of all. The basic reason of the Joseon’s financial burden was too many Japanese who sailed over to Joseon. Thus, information about Kyushu and Tsushima which brought a tribute to Joseon was necessary to control the them. This is the reason the first Joseon Tongsinsa was sent to Japan. King Sejong started to control Japanese traders with that information. But the full implementation had to be postponed owing to the two conquests of Pajeo-gang caused by Northern area problem. After the conquests, various policies had been enforced actively. Although Kyushu and Tsushima were in the middle of a civil war, King Sejong sent the second Joseon Tongsinsa to Japan in 1439 to get information of both island and figure out which one would more advantageous in the diplomatic strategy. Finally, Joseon and Tsushima signed several treaties, and they had come into effect since 1440. There was a discussion on Japanese fisheries in Gocho-do after the second Joseon Tongsinsa’s returning as well. Meanwhile, despite of two conquests, the barbarians from Ming reunited and threatened Northern domain of Joseon again under their emperor’s permission. King Sejong needed to settle the amicable relations with Japan to concentrate on solving the problem in Northern domain which was relatively important. King Sejong planed to control Japanese by reclaiming diminished authority of the ruler of the Tsushima caused by continuous civil war. Thus, it was allowed for Japanese to fish in Gocho-do and to share the benefit of Doseo·Munin policy. Later, Joseon focused on calming down the commotion of Northern area, it led to 4gun 6jin policy which was completed around 1443. Meanwhile, Joseon and Japan signed the Gyehaeyakjo in the same year.

Recently modern people spend more than 80 percent of our day indoors, so the importance of indoor air quality is increasing day by day. Tobacco smoke, one of the things that has a bad effect on air quality, is one of the lingering. Among the harmful substances in cigarette smoke, radon, formaldehyde, carbon monoxide, carbon dioxide and fine dust are the main factors that adversely affect the quality of our air. Measurement of air quality through moisture content to solve this problem shows that moisture does not affect air quality reduction, given that substances such as fine dust, carbon dioxide, and formaldehyde increase during humidification.

본 연구의 목적은 코로나바이러스 유행이 대학생들의 불안, 우울, 공포 및 스트레스와 같은 부정정서에 미치는 영향을 알아보는 것이다. J대학교에 재학 중인 대학생을 대상으로 인터뷰를 실시하였으며, 시간에 따라 부정정서의 변화 양상을 살펴보고자 2019년 3월, 2020년 3월, 2020년 11월 세 시기를 측정하였다. 조사 시점이 2020년 11월로, 2019년 3월과 2020년 3월에 겪었던 정서 기억 회상을 돕기 위해 연구 참여자에게 당시 겪었을 법한 상황에 대한 구조화된 인터뷰 질문을 하고 답변에 대한 요약정리를 하도록 요청하였다. 세 시기의 부정정서에 차이가 있는지 살펴보기 위해 반복측정 변량분석을 실시하였고, 부정정서의 변화 양상을 살펴보기 위해 다항식 추세 분석을 실시하였다. 연구 결과 세 시기의 부정정서에 차이가 있었으며, 2019년과 비교하여 2020년 3월에 대학생들이 우울, 불안, 공포 및 스트레스를 더 느끼고 있었으며, 이러한 부정정서가 2020년 11월까지 지속되었음을 알 수 있었다. 이러한 결과는 코로나바이러스의 영향이 지속되고 있는 현재에도 대학생들이 부정정서를 겪을 수 있음을 시사한다. 본 연구의 결과는 코로나바이러스 유행 상황에서 대학생이 겪을 수 있는 부정정서의 양상을 나타내며, 결과를 바탕으로 대학생을 위한 스트레스 관리 지침 및 심리 상담과 같은 심리지원체계 제공의 필요성이 제시되었다. This study aims to investigate the effect of the coronavirus disease 2019 (COVID-19) epidemic on negative emotions, such as anxiety, depression, fear, and stress, in Korean college students. The study recruited students from J University and conducted interviews across three time points, namely, March 2019, March 2020, and November 2020. For three time points, the participants responded to structured questions about situations they may have encountered and they were asked to summarize their responses. Repeated-measures ANOVAs were performed to examine whether differences exist in negative emotions between time points. Furthermore, polynomial trend analyses were conducted to examine resultant patterns over time. The results revealed that negative emotions displayed significant differences between time points. Moreover, trend analyses revealed a curvilinear pattern, which indicates that negative emotions increased and were then sustained. These findings suggest that negative emotions may continue to become prevalent among college students with the increased impacts of the ongoing COVID-19 pandemic. The study discussed the need for psychological support systems, such as stress management and psychological counseling, for college students.
