In this study, we conducted the levels of pesticide residue as well as the risk assessment for pesticides which exceeded maximum residue limits(MRLs). A total of 345 Agricultural Products (239 Vegetables and 106 Fruits) for raw juice were distributed from the southern area of Seoul from January to August in 2021 for 280 types of pesticides were analyzed by multi-residue method in Korean Food Code. As a result, Occurrences of violation Max Residue Limits(MRLs) of pesticide residues were found in the 4 samples(3 kales and 1 celery, 1.2%). However, the levels of residual pesticides in Fruits were not exceeded MRLs. Pesticide residue levels in 60 cases(33 fruits and 27 vegetables, 17.4%) reveal to the below the standard limits. The detection rate of pesticides in fruits for juice was 31.1%, which was about three times higher than the 11.3% of vegetables. The most commonly exceeded their MRLs pesticides residues were three types of pesticides(paclobutrzol, fluopyram and vinclozolin). The safety levels of these residual pesticides that exceeded MRLs was assessed using the ratio of estimated daily intake(EDI) and acceptable daily intake(ADI). The results showed that their ratios were between 0.34~1.43% of ADI, which indicated that these pesticides were within the safe limits.

Unilateral pulmonary agenesis is uncommon congenital malformation which refers to total absence of pulmonary parenchyma and blood vessels as well as bronchia beyond the tracheal bifurcation. And, it is rarely to make prenatal diagnosis. Indirect prenatal sonographic findings in this malformation include mediastinal shift of the heart together with lack of evidence of diaphragmatic hernia. And more reliable diagnosis is obtained by Doppler sonographic finding with lack of branching of the pulmonary artery. Its prognosis depends largely on the presence of associated other congenital anomalies. But unilateral pulmonary agenesis does not result in the death of the infant and is compatible with long-term survival. So, selective termination is not recommended. In the case herein, right pulmonary agenesis of one fetus in a monochorionic twin pregnancy was diagnosed by prenatal sonography. We describe this case with a brief review of the literature.

The hypopharyngeal gland (HPG) of the honeybee worker produces royal jelly (RJ) and has a developmental cycle closely related to the division of labor. In this study, we investigated to compare the HPG acini diameter of differently aged worker bees with high royal jelly producing colony (HRC) or less producing colony (LRC). Additionally, we also evaluated whether the fresh weight of the head is a reliable indicator of the developmental status of HPG. The HRC showed a significantly higher RJ production about two-times as compared with those of the LRC. We measured the HG-diameters on days 1, 3, 6, 9, 12, 15. The microscopic analysis revealed that the acini size of the HRC was significantly larger than the LRC. In addition, the acini diameter of HRC was 15% longer than the LRC on the first day after emerging. It was shown that the fastest development during 3 days which is preparing for nurse the brood. The HPG acini diameters increased in both colonies in a similar fashion until day 12 and then decreased. We also compared the fresh head weight of the experimental colonies, differences were similar to the development of HPG. Therefore, high royal jelly production may have a positive correlation between HPG acini size and the fresh head weight.

Retroperitoneal inclusion cysts are uncommon mesothelium-lined cysts seen in the pelvis of reproductive-age women. It presents as a pelvic mass or with pelvic pain and may be misdiagnosed as an ovarian malignancy. Although benign, local recurrences are common, often requiring repeated surgeries. We report a case of retroperitoneal inclusion cysts, which was diagnosed clinically as benign multilocular cyst of ovary; however, it turned out to be retroperitoneal mesothelial inclusion cyst on histopathology. A 55-year-old postmenopausal woman referred to our outpatient department with intermittent lower abdominal pain. Results of routine blood investigation and CA-125 were within normal limits. A pelvic MRI showed a cystic ovarian tumor, approximately 7 cm in diameter with numerous septated small cysts. We performed a laparoscopic surgery on April 19, 2016. First, we removed extensive adhesions on pelvic wall. After confirming no abnormalities in both ovaries, we opened the peritoneum to investigate retroperitoneal space. There was a cystic multiloculted mass firmly attached to the right ureter and the pouch of Douglas. The lesion was friable and to avoid rupture of the cyst and spillage of the cystic fluid, meticulous care was taken. Complete resection of the lesion was performed. Postoperative recovery was good and the histopathology showed benign cystic mesothelial lesion. We present this case along with a video clip.

Objective To analyze the preoperative diagnostic clues to ovarian pregnancy (OP). Methods This study conducted a retrospective chart review of 23 patients with OP and 46 patients with tubal pregnancy (TP) from October 1, 2003 to September 31, 2016 in Hanyang University Hospital. Results There were no significant differences in demographic and clinical characteristics between the two groups. The presence of an ectopic gestational sac and hemoperitoneum was significantly higher in the TP group (13.0% vs. 95.7%, P=0.000; 13.0% vs. 54.3%, P=0.001, respectively) in preoperative ultrasonogram. The OP group had more ruptured ectopic gestational sacs than the TP group (73.9% vs. 45.7%, P=0.039) in surgical findings. Conclusion For the patients in whom a gestational sac is not detected in the uterus or the fallopian tubes, it is important to be aware of the possibility of OP and rupture of an ovarian gestational sac to promote early diagnosis and surgical intervention.

이 연구는 예비공학교육을 통한 미국의 국가 경쟁력 제고를 위하여 만들어진 프로그램의 내용을 살펴보는데 있다. 미국의 PLTW(Project Lead The Way)는 대학의 공학을 준비하기 위한 예비 공학 프로그램으로서 정규 교육 과정으로서가 아니라 공학을 위한 지식과 직업과 관련된 기본적인 경험을 제공하는 프로그램이다. 주요 내용은 미국의 과제중심 진로교육(PLTW)을 소개하고 초ㆍ중ㆍ고등학교 프로그램을 조사함으로써 우리나라 교육과정에 도입, 적용하는 방안을 모색하는데 있다. 이 연구에서 조사된 내용을 종합하여 다음과 같은 결과를 얻었다. 첫째, PLTW는 교육 시스템으로부터 졸업한 공학자와 공학 기술자의 양과 질을 늘이기 위한 공립 초ㆍ중ㆍ고등학교, 단과 대학 및 종합 대학의 고등 교육 기관과 민간 부문 사이의 협력을 맺은 프로그램이다. 둘째, PLTW는 예비공학 프로그램으로 6-12학년(초등학교 6학년~고등학교 3학년) 학생을 위해 공학에 기초 훈련을 제공한다. 이 프로그램은 공학과 공학 기술을 위해 2-4년제 대학이나 공업학교(technical school)에 입학하기 위한 필요한 것으로 학생들에게 제공하는 프로그램이다. 셋째, PLTW는 공학과 공학 기술 프로그램을 추구하여 2-4년제 공과 대학의 학위를 필요로 하는 학생 수를 증가시키고, 성(gender)이나 인종적 태생과 관계없이 배우고자 하는 학문적 자격 있는 학생들에게 공정하게 모든 기회를 제공하여, 미래에 공과 대학이 감소하는 비율이 작아지도록 하는데 필요한 프로그램이다. 넷째, 우리나라도 실업계 및 공과대학 인력 흡인책으로 PLTW와 같은 프로그램을 초ㆍ중ㆍ고등학교 교육과정의 도입을 검토할 필요가 있다고 인식된다. The purpose of this study was to investigate the Program which was made to enhance the national competitive of America through Pre-engineering eduction. PLTW(Project Lead The Way) of America is Pre-engineering Program to prepare engineering of the university, not as a regular school curriculum but as a Program offering basic engineering knowledge and occupation related with essential experience. The main contents of this study were consisted of introduction of PLTW, and to survey the Program of elementary, middle and high school of U. S. A and furthermore using the above results, we try to reasonably find the way to apply the U. S. A PLTW to our schooling system The main findings of this research were as follows: l) PLTW is the Program forming partnerships among Public schools, higher education institutions and the private sector to increase the quantity and quality of engineers and engineering technologists graduating from education system. 2) PLTW as Pre-engineering Provides basic training of engineering for 6-12 grade student(i.e., 6th grade of elementary school- 3rd grade of high school in Korea). This Program was made to give opportunity to the students who wish to enter to two-and four-year college or technical school. 3) PLTW was made to increase the number of students who wish to earn bachelor or associate bachelor of engineering, to fairly give equal opportunity to all the students regardless of gender and race who wish to study engineering field in the future, and then to make the rate of reduction of the application for engineering colleges less than before. 4) PLTW is also required for the our schooling systems in order to increase the application and technical high schools and engineering college in Korea.
