This study examined the relations among toddlers' temperament, maternal parenting, and toddlers' social withdrawal and aggression. One hundred and two mothers of two-year-old children (49 boys and 53 girls) completed questionnaires and Q-sort. Data were analyzed by correlation analyses and regression analyses. First, toddlers' pleasure was negatively related to social withdrawal, while social fearfulness was positively related to social withdrawal. Also, toddlers' activity level and anger proneness were positively related to aggression. Second, the encouragement of independence in maternal parenting was negatively linked to toddlers' social withdrawal, and maternal rejection was positively linked to toddlers' aggression. Third, toddlers' pleasure and interest/persistence were positively associated with mothers' encouragement of independence, and toddlers' activity level and anger proneness were positively associated with mothers' rejection. Finally, mothers' encouragement of independence acted as a mediator between toddlers' pleasure and social withdrawal. Also, toddlers' activity level and anger proneness influenced aggression through maternal rejection. These results indicate that toddlers' temperament and maternal parenting play crucial roles in the development of toddlers' maladaptive behaviors such as social withdrawal and aggression.

Plummer-Vinson syndrome(Paterson-Kelly syndrome) is characterized by dysphagia due to upper esophageal or hypopharyngeal web, iron deficiency anemia, and atropic oral and glossal mucosa. This syndrome is usually known as precancerous lesion that develops into postcricoid carcinoma. Universally, the clinical manifestations of this syndrome were markedly improved after oral iron replacement therapy or endoscopic balloon or electrocautery treatment. 63 year-old woman was received a short segment, free jejunal transfer to be released from esophageal stricture. After the operation, the stenotic lesion proved to be Plummer-vinson syndrome with carcinoma in situ by pathologic study.

Objective: The aim of this study was to introduce gastric dysmotility as a common cause in patients with concurrent functional dyspepsia and chronic atrophic gastritis. Method: Dyspeptic symptoms, the Rydoraku score, gastric motility (electrogastrography, bowel sound analysis), gastric mucosa (gastroendoscopy), and blood and blood chemistry were all evaluated. For the treatment method, Pyengwi-san (solution) and Banwhasashim-tang (extract) were used as herbal drugs. Both ST36 electrical stimulation and simple immersion stimulation of CV11, 12, and 13 in the abdomen were applied. Results: Dyspeptic symptoms including indigestion, headache, and insomnia were all relieved. Gastric myoelectrical activity and gastric pyloric function were additionally improved. The condition of the gastric mucosa was changed from atrophic to erosive. Other side-effects of the treatment were not noted. Conclusion: The traditional Korean treatment showed effectiveness in the relief of dyspeptic symptoms and mucosal improvement of chronic atrophic gastritis. Gastric dysmotility is a common cause of the condition being concurrent with both functional dyspepsia and chronic atrophic gastritis without Helicobacter pylori infection.

In case with severely atrophied mandibular ridges, it may be difficult to achieve adequate retention and stability of dentures through the normal functional impression process of complete dentures. In these patients, an approach using the neutral zone raising technique may be an effective alternative. The neutral zone is defined as the area where the pressure of the tongue towards the outside of the mouth and the pressure of the cheek and lips towards the inside are balanced during the normal oral function of the muscular-nervous system. Complete dentures made through neutral zone impression not only improve retention and stability, but also provide adequate tongue space in the posterior teeth area. Additionally, food residues are reduced in the area around artificial teeth, and aesthetics are improved through appropriate facial support.

방위산업은 기간산업의 성격을 지닌 분야로서 범 정부 차원에서 관심과 지원이 필요한 산업이다. 방산업체의 가동률 저하, 수익성 악화 및 제도의 경직성 등으로 방위산업 전반에 걸친 경영환경이 침제될 경우 이는 방산업체만의 문제가 아니라 국가 산업기반이 위축될 수 있는 상황을 초래할 수도 있다. 따라서 업체는 경영 합리화를 통해 생산의 효율성을 극대화하고 낭비적 요소를 사전 제거할 수 있는 선행관리 활동을 강화하여야 하며, 이러한 업체의 자구노력에 정부도 연구개발 사업을 확대하고 중장기적으로 수요의 균형이 이루어 질 수 있도록 공동 노력하여야 한다.

성이 넘쳐 나는 시대, 성의식 개방과 더불어 이를 모티브로 한 사업은 그다지 경기영향을 받지 않는 특성을 가지고 있다. 최근 이러한 성관련산업이 크게 발전하고 있는 가운데 성인용품자판기 시장 역시 지난 한해 큰 시장성공을 일구어 냈다. 성인용품에 대한 인식확대와 수요확산과 더불어 익명성이 보장이 되는 유통수단이라는 제품성격이 모텔 등의 숙박업소의 니즈와 절묘하게 맞아 떨어진 점이 인기의 비결이다. 그러나 이러한 시장 인기가 지속력을 보이지 못한다는 데 문제가 있다. 최근 들어 성인용품 자판기 시장은 설치 로케이션의 제약성, 기대만치 높지 않은 운영수익성 등의 문제로 시장이 위축되어 가는 양상을 보이고 있다. 금호 테마기획에서는 성인용품자판기 시장의 현황을 살펴보고, 지속적인 유망시장으로 자리매김하기 위해서는 어떠한 선결과제들이 있는 지를 살펴봤다.

Silage yield Potential and some agronomic characteristics of Korean improved and introduced corn hybrids from the United States were tested for five year in Gyeongsan, Gyeongsangbug-do and for one year in Hongcheon, Gangwon-do. 1. At 20 days after emergence, plant height and dry matter of hybrids were different, while the early growth of the hybrids was not correlated to the culm length and silage yield. 2. In Cyeongsan, silage yield potential of Suwon19 was relatively high, while most susceptible to rice black-streaked dwarf virus (RBSDV) disease and leaf senescence at harvest time. In contrast, silage yield potential and resistance to RBSDV of Cwanganok were moderate, while susceptible to leaf senescence at harvest. Generally, Suwon19 showed similar or higher yield than most introduced hybrids, while some introduced hybrids showed lower silage yield than Korean improved hybrids. Most introduced hybrids were more resistant to RBSDV and leaf senescence at harvest time compared to Korean improved hybrids. 3. In Hongcheon, silage yield of three Korean improved hybrids were lower than that of NC+5514 and DK729, while similar or higher than other introduced hybrids. af senescence of all Korean hybrids was severer compared to introduced hybrids.

Vascular malformations may typically present with palpable mass that can be either asymptomatic or can present with symptoms including swelling and pain. On rare occasions, vascular malformation of muscle may produce joint deformities caused by contracture of the involved muscle. When vascular malformation involves the flexor muscle of the leg, ankle equinus deformity may occur. However, there are no reports of toe deformities secondary to intermuscular or intramuscular vascular malformations of flexor muscles of toe. Thus, we report a case of vascular malformation of flexor hallucis longus muscle with flexion contracture of toes in a 40-years-old woman who was treated with surgical excision.

The purpose of this study was to examine validity of the Korean-Child Behavior Checklist: K-CBCL) as measures for emotional and behavioral problems for use with children with autism spectrum disorders. In present study, the factor of the K-CBCL was investigated, using data of 248 children with autism spectrum disorders, with 11.17 mean ages. The two factor model of Internalizing problems (Withdrawn, Somatic Complaints, Anxious/Depressed) and Externalizing problems (Delinquent Behavior, Aggressive Behavior) was investigated by the confirmatory factor analysis. The two factor model of K-CBCL was adequate for children with autism spectrum disorders. The inter-item consistency for the sub-factor of K-CBCL demonstrated on adequate reliability of the measure. Although the inter-item consistency of Withdraw, Social problems, Delinquent Behavior was not acceptable, the inter-item consistency of Internalizing, Externalizing and total problems were good. This results supported validity and reliability and suggested that K-CBCL is used to assess for emotional and behavioral problems in children with autism spectrum disorders.

This study is objected to identify the influencing factors of adolescents' smartphone dependency and to determine the degree of influence on smartphone dependency through direct and indirect channels acting between factors. The data of the 2th Korean Child-Youth Panel Survey(KCYPS 2018) was analyzed using the SPSS 26.0 and 26.0 AMOS program. Six paths proved to statistically significant. Self-esteem and depression were the influencing factors of adolescents' smartphone dependency. Social withdrawal and the school environment influenced smartphone dependency through self-esteem and depression as mediators. Self-esteem and depression acted as mediating factors. Adolescents' smartphone dependency was influenced not only by personal factors but also by external factors such as the school environment. The results of this study will be presented as evidence for developing programs that can prevent adolescents from smartphone dependency.
