Spontaneous and isolated dissection of the limb arteries without involvement of the aorta is extremely rare, and has been reported previously in pregnant patients in association with collagen vascular disease, and in cases of high-energy trauma or intensive activity in athletes. There is no consensus yet on indications for medical or surgical therapeutic modality. Due to the rarity of spontaneous dissection of external iliac artery, its natural history has been poorly described. A healthy 50-year-old male with normotension was admitted with an acute onset of left flank pain. Left external iliac artery dissection was diagnosed by abdominal computed tomography.

Thoracic splenosis is a rare disease that develops as a result of autotransplantation of splenic tissue into the thoracic cavity following splenic and diaphragmatic injury. We report the case of a 53-year-old man with a chief complaint of heartburn and cough. He had a history of traumatic diaphragmatic rupture treated with surgical repair and splenectomy 15 years ago. Imaging studies revealed a paraesophageal mass, and surgical resection was performed considering the possibility of Castleman disease or an esophageal submucosal tumor. Pathologic results showed findings of normal splenic tissue. The patient was discharged on postoperative day 5 without any complications.

The food life of Korean people during the establishment of Republic of Korea and the Korean war was reviewed. After liberation in 1945, the division of South and North Korea, the establishment of the governments, and the ensuing Korean War made Korean society extremely chaotic and transformed. Consequently, data on Korean dietary life during this period (1945-1960) are scarce and unreliable. The author tried to reveal the food situation and health and nutritional status of Koreans during this period by examining the data released by the US National Archives and other review books. Regarding the nascent period of the food industry after the Korean War, data from the recent 50-year history of the Korea Food Industry Association has been compiled.

Acute rupture of the tibialis anterior tendon is rare, but the diagnosis is often delayed when it occurs. Acute rupture of the tibialis anterior tendon is often caused by minor trauma or it occurs spontaneously. Therefore, the diagnosis is more likely to be delayed. Among ruptures of the tibialis anterior tendon, longitudinal ruptures are less common and difficult to diagnose. Thus far, there are no reports of ruptures of the tibialis anterior tendon caused by direct trauma in Korea. This paper reports a case of chronic longitudinal tear of the tibialis anterior tendon caused by trauma in a 50-year-old male patient with no specific history of the disease, along with a review of the relevant literature.

Gardner syndrome has head and neck manifestations that may be recognized during dental visits. Features such as multiple gnathic osteomas, impacted supernumerary teeth, and multiple foci of idiopathic osteosclerosis can be easily identified on dental radiographs, prompting the clinician to refer the patient for further investigation. A dental examination and routine radiographs play a vital role in revealing the extracolonic presentation of Gardner syndrome, which facilitates timely screening and detection of colorectal cancer and other malignancies associated with this condition. This report discusses the case of a 50-year-old Caucasian man who presented with a hard swelling of the left angle of the mandible and was diagnosed with Gardner syndrome based on abnormal findings from an oral examination, dental imaging, and medical and family history.

Marfan syndrome (MFS) is an inherited connective tissue disorder with a mutation in the fibrillin-1 (FBN1) gene. Fibrillin is a major building block of microfibrils, which constitute the structural component of the connective tissues. A 10-year-old girl visited our hospital with the chief complaint of precocious puberty. According to her medical history, she had a pulmonary wedge resection for a pneumothorax at 9 years of age. There was no family history of MFS. Mid parental height was 161.5 cm. The patient's height was 162 cm (>97th percentile), and her weight was 40 kg (75th-90th percentile). At the time of initial presentation, her bone age was approximately 11 years. From the ophthalmologic examination, there were no abnormal findings except myopia. There was no wrist sign. At the age of 14 years, she revisited the hospital with the chief complaint of scoliosis. Her height and weight were 170 cm and 50 kg, respectively, and she had arachnodactyly and wrist sign. We performed an echocardiograph and a test for the FBN1 gene mutation with direct sequencing of 65 coding exons, suspecting MFS. There were no cardiac abnormalities including mitral valve prolapse. A cytosine residue deletion in exon 7 (c.660delC) was detected. This is a novel mutation causing a frameshift in protein synthesis and predicted to create a premature stop codon. We report the case of a patient with MFS with a novel FBN1 gene missense mutation and a history of pneumothorax at a young age without cardiac abnormalities during her teenage years.

The aim of this study was to review the history of dental hygiene education in Korea on its $50^{th}$ anniversary in 2015. Internal resources and documents from the Korean Dental Hygienists' Association and other accessible resources were examined to verify the historical facts of dental hygiene education in Korea. From 1965 to 1967, the first class of four dental hygiene students graduated, and the legal basis for dental hygiene as a profession was established, which led to the start of the profession Registered Dental Hygienist in 1971. From 1977 to 1993, 13 higher educational institutions started dental hygiene programs. The Korean Dental Hygienists' Association (1977) and Korean Association of Dental Hygiene College Professors (1987) were established in this period. From 1994 to 2006, the duration of major-intensive course programs in dental hygiene was extended to three from the two years of 1994, and the first bachelor's degree program in dental hygiene started in 2002. In this period, studies on dental hygiene became significantly active owing to vigorous activities by academic societies. The master's degree program in dental hygiene was established in 2007. Academic dental hygiene journals, the Journal of Dental Hygiene Science, and Journal of Korean Academy of Dental Hygiene Education were promoted as the registered journals of the Korean Research Foundation. From 1965 to 2015, dental hygiene education in South Korea expanded both quantitatively and qualitatively and is now ready for further progress in the future.

This paper aims to examine from various perspectives how domestic research studies and projects related to climate change have been conducted to mark the 60th anniversary of the Korean Meteorological Society (KMS). The 『50-year History of the Korean Meteorological Society』, published more than a decade ago, has never dealt with the history of development of individual fields of meteorology such as climate change. Therefore, it is of significance to look at the history of research activities and studies achieved by KMS members in the area of climate change over the past 60 years. The research on climate change in KMS is classified by era from the beginning to the latest and the contents are examined by major research projects at that time. During the past 60 years, climatological research in KMS has been mainly focused on general climate, synoptic climate, and applied climate (urban climate) until the 2000s. However, since the 1990s, climate change has become an important area for climate research. The 2000s are the beginning era of climate change research, since the major projects and researches for climate change has begun in the period. The 2010s can be a time when climate change prediction and monitoring are expanded and refined to meet the rapidly increasing demands for climate information from a wide range of areas. We concluded that the development of the research capabilities of the society over the past 60 years, in particular in the past two decades, in the field of climate change research is remarkable.

The formation of design in Korea and the consensus on it's necessity began in 1960's. Industrial design started to be realistically recognized and formed with the establishment of The Korea Industrial & Packaging Design Center. Later on, the industrialization in 1970s has contributed to industrial design campaigns. Now industrial design in Korea shows almost 50-year-long history respectively, and the nation's GNP soars over $ 10, 000. This study focuses on the promotion of effective advances in graphic design, which is said to be most essential in the industry. For this, graphic designer's view on their occupation and the world with their anticipation towards further development of graphic design has been discussed.
